GS Racing Storm Unlimited Truck

[sutman]

Yeah, you know the weather in england always raining :( . I have put 100,000 in the centre diff, 60,000 in the front, and 10,000 in the rear.
As for hop ups ive gone for hitec, throttle servo 5625 and 5645 for steering. I have changed the shocks for pro ones,(i found the standard ones kept popping the top). Fioroni chassis braces, pro steering plate and standard plate glued together. Front and rear sway bars, and added a rear wing from the storm.And hinge pin support bars. Also two brake discs, front and rear. And a Fioroni turbo clutch with carbon shoes. Ive kept the standard engine and pipe,I keep looking if i can find anything better, but i can't!
One modification i had to do to the bumpers is a nut and bolt through the diff case to stop them ripping off.
Just ordered a Fioroni chassis as ive found the suspension hinge pin screws are starting to wear through the edge of the plate. I'm waiting on that hopefully tomorrow as ive got a race on sunday, and i need to rebuild it.

[erikderaaf]

wheather in the netherlands isn's much better at the moment, still waiting for the summer....

what kind of plug is everyone using in their sut? are nr 3-4-5 best for the engine?
i dont know what plug is used standard in the rtr version!

[PhsykoManMKAO]

after 5 tanks i was suprised to find that a product from gs had a pin hole in the fuel line. lol, so i replaced the fuel line and havent had a problem since.
i set my battery pack up on the front brace, the switch in the rear shock tower and the reciever + failsafe on the chassis where the box used to be. i ran the wires around the left side of the engine using a slit piece of fuel tubing.

wonder if that works...

[erikderaaf]

I would reccomend that you put your elektronics (reciever) in a balloon or something to keep dirt and water out (I almost wrecked my synthesizer reciever yesterday because of mud)

[sutman]

PhsykoManMkao why have you spread the radio gear around the truck? Be careful of the wires running by the flywheel, if the wire breaks you will lose power to your failsafe making it u/s and truck will be off like a rocket

[PhsykoManMKAO]

well i wanted a little more weight in the front and also, the battery box is to cramped. im going to continue the slit fuel tubing up the rest of the way of the wires also.
a little dust wont hurt the radio gear, and dont worry, the truck wont ever be seeing mud or water. (until the failsafe fails and it shoots off across the road into the pond next door. )

[nitrojunk]

does anyone know is GS will have a 2 speed for the SUT? has anyone tried a 2 speed from like a Ofna Buggy?

[erikderaaf]

i'm still wondering what type of plugs you are using in de r25mt...
im still using the standard one, works well, but i dont know the type or a part no of it, and still no reply from gs...
does anyone here know the part no of the standard plug

otherwise i think i'm going to use a GS or rossi 4 maybe 5, what would be better??

and nitrojunk, i don't think a 2 speed would be neccesary because mine can keep up with savages, even outruns them on acceleration and top speeds!

im using an o'donell plug but i think i need to run a colder plug. im not sure what o donell it is, i got them off my uncle.
and about the 2- speed... i REALLY dont think thats nessacary... lol

[Monsterbrad]

I run MCCOY #9 plugs
I also use rossi c-6 s
They both work very well in all conditions.

[PhsykoManMKAO]

.. starter box wont turn over the mt25... and my pullstarter broke
will one from an xtm .18 fit on it. it looks like it, im going to have to try it out.
its a dynamite starter box, hooked up to a 12v car battery.
wouldnt turn the motor over... so i tried jumper cables instead of 16 gauge wire... LOL i had those little 550's smokin... till they quit workin.
still didnt turn it over.

[Monsterbrad]

I would say try taking the plug out and turning it over a bunch of times make sure it is not flooded.
Sounds like you flooded it badly thats why its not turning over.
Or you blew it up and something broke inside.
HOw old is the engine??

[doesgo]

Monsterbrad, you are so right. The SUT is a GREAT jumper! I never really tried it before except a little on the track, but I ran it this past weekend on my homemade wood jump and it flew beautifully! Very little throttle/brake correction needed for perfect landings, it was so much fun.

[doesgo]

Is the Storm Pro chassis a direct bolt-in for the SUT or do I need to do some mods to it to make it work? Will the stock engine mounts work or do I need Pro mounts?

[doesgo]

I can't find an SUT piston/sleeve set (GS-9921361) for sale anywhere, nor can I find anything about an SH .25 engine. Is the XTM 24.7 truly the same internally as the GS R25MT? In other words, could I buy a piston/sleeve for an XTM 24.7 to go into my R25MT engine?

[Monsterbrad]

Call Speed Zone raceway in TN
1-866-590-0763
Mike might be able to help out.

[doesgo]

Thanks Monsterbrad.

brand new. and no i didnt even prime it so it shouldnt of been flooded.
oh well i got the pullstarter on it now and it'll start... after a while, still need to get the fine adjustments in.

edit: and guys the sut is a number one free style jump. back flips front flips. wheelies and 2 wheel turns. ive done them all with the sut, havent mastered any though yet :eek: lol i cringe everytime i dont plant a front or back flip.

[Monsterbrad]

i do like jumping this truck also but the suspension is just not there.
Don't get me wrong I love this truck but its more of a buggy on steroids than a monster truck.
Have my eye on a new LST though
back flips with this truck are easy as long as you can land them I landed on the lid to many times trashed the body and wrecked the radio tray. Broke it next to the throttle servo.
Still a great truck though easy to work on and simple un like all these other monster style trucks.I sold my savage cause of the crappy set up for working on it.

[thedarkness]

Ok im bored and this is just an idea but would it be at all posible to transplant savage suspension on this truck?I have both trucks sitting beside me and feel like doing something dumb.If anyone has any ideas for my mutant project feel free to shout them out and thanks in advance.

[nitrojunk]

Hey getting a SUT on friday.. I cant wait .. I already have a Savage, but the SUT always called my name when ever I saw it.. Well its on its way to my house... I have a Sirio .27 to drop in it. Anyone know how I can setup the diffs to accamidate this beast of an engine? 10,000 7,000 3,0000 sound ok?

10 front 5 middle and 3 back i heard is good.

[Monsterbrad]

I run 10,000 in the front
100,000 in the center keeps the front tires from unloading under power.
and 3,000 in the rear
All works great just still having problems with clutch bearings and the shoes over heating.

[doesgo]

I run 10K, 30K, and 5K with very good results.

[Monsterbrad]

Has anybody tried the pro conversion kit for this truck yet?

[nitrojunk]

QUick QUestion..

What clutchbell size come on the RTR SUT?

What clutchbell size would you guys recommend for a .27 Sirio in the SUT?

[doesgo]

I'm not going to do the full Pro conversion, but I'll be putting on a Pro chassis and probably shock towers in the near future, along with hinge pin braces (but those will probably be from Holeshot Engineering since I can't get the GS Pro parts anywhere). My chassis is slightly bent at one of the arm mount screws but I've got a race tomorrow so I won't have time to convert before that, but hopefully shortly thereafter. I'm hopeful the thicker(?) and stronger Pro front shock tower will prevent bending and also keep the hole through which the upper arm hinge pin passes its proper size. Both my Storm's and SUT's upper inner hinge pins are slightly loose in the shock tower hole. Then again, if the tower is thicker, my hinge pin won't be long enough. Argh!!!!

I think the stock clutch bell has 12 teeth. I'd start there and see what your Sirio likes. You could probably bump it up by a tooth or two depending on the characteristics of the Sirio engine, but the stock GS25 is quite torquey and the 12t works well with it. It's a good place to start, at least!

[thedarkness]

Ive done the math and with stock gearing and a sirio .27 you should be seeing 50 mph.Doesgo i seen in the heat video what happend to your sut i would have been angry but then again thats racing.Looking over my sut the rear shock tower is bent and im missing a rear dogbone and something is up with the front diff.Oh well time to order parts to bad i live in northern canada and i will have to wait 2 weeks to drive any of my cars(savage stripped spur order that too)

[doesgo]

50mph with a single-speed truck! That's awesome.

I was really pissed at first about the incident, but like you said, stuff happens. He shouldn't have pulled out of the pit right then, but to his credit he stayed way right. I didn't expect him to and tried to to go to the right of him and we hit, then I hit the fence post, and I broke a rear arm mount screw. It was just a qualifying race and I got it fixed so it wasn't the end of the world.

Two weeks for parts? I think I have an extra 52t Savage spur, would it get there any faster than from the mail-order places if I sent it to you?

[thedarkness]

Your in minissota right Doesgo?How much would you want for the spur gear?I would gladly purchase it from you.Thanks for offering the spur gear, your a life saver.Looks like i owe you one now.(well more than one but whos keeping track)

[doesgo]

We can settle up later, the main thing is to get your Savage up and running! Shoot me an e-mail at doesgo@slapmafro.com so I can get your address.

[erikderaaf]

QUick QUestion..

What clutchbell size come on the RTR SUT?

13T should be your standard clutch bell

i personally think this will do very wel with a sirio, as this engine will have more torque then the r25 and that one is already very fast.

maybe soon i'm going to bolt in a picco p3 from a friend and see how that goes.....

[thedarkness]

Has anyone seen horizons online price for the blue rtr sut?
heres a link to the red one: http://horizon.hobbyshopnow.com/products/description.asp?prod=GSC2005
And heres the blue one: http://horizon.hobbyshopnow.com/products/description.asp?prod=GSC2005E

Both prices are high to begin with but $200 more for a blue body.Horizon also has a pro spec rtr listed.Will this be the pro sut in a rtr?

[doesgo]

That's hilarious! Even the $520 price for the red one is crazy. i got mine for $440 at an LHS that's known for high prices!

[nitrojunk]

Hey Doesgo..

Do you get any tire ballooning in the front with 10,30, 5 diff oil setup?

I was driving mine around this weekend and even with the stock engine the front tires balloon.. Very hard to control it like that..

If you get ballooning then what would you recoomend for my sirio?

[doesgo]

At first I got quite a bit of ballooning with the stock tires with no diff oil, now even with soft Bowties and Mulchers I get no ballooning. I don't really know that running a more powerful engine typically requires thicker lube or not.

Marty Korn (GS factory racer) runs 10/30/3 for the SUT. Now that I think about it, I think that's what I have as well (rather than 5K in the rear). For anyone who hasn't seen it, here's some other stuff he said about racing his SUT (this pulled from another forum):

"These are the things that i changed on my mt........i put med. Shocks
In the front instead of longs. I doubled the steering rack for
Strength, i cut coils off the springs for a lower ride height, can't
Remember how many,mounted the gas tank on pieces of fuel line for
Safety,tightened the servo saver way up,added swaybars,changed to a 12t
Clutchbell,removed mt bumpers,they are unnecessary,changed to
Universals everywhere,and put nuts on top of the suspension mounts for
Safety.with these changes you will have little if any problems. Instock
Form you will have little if any problems. Here is my setup.50wt front
Shocks,30wt rear, 30,000cent diff,10,000 front diff,3,000 rear diff,all
Shocks in middle hole on arms,middle hole on steering rack,that should
Be good to get you going. Oh yeah, i ran alum chassis braces."

The only things I would add to this "To Do" list are to use stronger/thicker shims under the shock pistons (Yokomo hardened stainless steel diff thrust bearing washers are perfect) and get some high-grade arm mount screws. I've been having problems pretty much every race or bash day with at least one arm mount screw shearing, but after installing eight high-quality 10.9-grade M4x20 screws from Tony's Screws my SUT held together perfectly for an entire race day and several tanks of bashing and some jumping the day after the race. The screws and chassis all look great still. Previously, often even the screws that didn't break did bend, which can lead to messed-up screw holes in the chassis. All eight screws in my SUT still look perfect. I did the same in my Storm which also performed flawlessly this weekend.

[nitrojunk]

thanks .. Im going to tray that

[garen]

guys, you can email your questions to me at garenh@gsracing.com . it is much easier for me to answer through email than to sift through the conferences...especially since rcca reshuffled the threads.
-Garen

[nitrojunk]

are there ant carbin fiber pieces to replace the blue aluminum ones on the SUT? Like the servo tray and such?

[doesgo]

Thanks Garen, that's really cool of you.

I'm happy to say it was a GREAT weekend for GS in my little part of the world! I TQ'd and won the Monster Truck Unlimited class with my SUT AND the Sportsman Buggy class with my Storm last Saturday! I was actually getting slightly better lap times with my SUT than my buggy for some reason too. Surprised me because I've not felt as comfortable driving the SUT as the buggy until now, but I'm really learning the SUT lately. I love it! My next race isn't for a month so I did some jumping with the SUT yesterday....man that thing flies nice! :) I'm gunning for the series championship with both of these vehicles in September, things are looking good so far!

[nitrojunk]

Can anyone list online shops that sell stuff for the SUT? Im looking for the Long Shock Spring Kit and Stormers is out fo them.. were else can I check?

Do any buggy springs fit?

[doesgo]

The SUT RTR uses rear buggy shocks on all four corners, so the rear buggy springs do fit.

[nitrojunk]

thanks.. WHat does the pro Use ? I saw on stormer they have Short, Medium, and long shocks for the SUT

[doesgo]

That I don't know! Garen? Fidelio? Monsterbrad? Anyone?........Bueller?

[thedarkness]

Wow no posts here in a long time.Anyways i was chatting with clayton from vertigo performance I asked him if he would make parts for the SUT.Long story short he is now looking into it.Just need to find everyone that has an SUT or storm And see if there interested.Also what sh/xtm engine is the gs 25? I thought it was the xtm24/7 regular, but i tokk of my head today and theres 6 ports would that make it the pro?

[doesgo]

Sounds good to me! I love my SUT and Storm and I don't see parting with them anytime soon, so I see myself as a future customer of Vertigo.

GS Pro parts are pretty good and address most of the shortcomings of the RTR Storms, I believe, but they sure are tough to get!

[doesgo]

Well, the XTM 24.7 Pro is a six-port engine, right? Hmmmm, very interesting!

[Monsterbrad]

I will have to say for a single speed truck the stock 25 engine is great runs awesome but I think the truck needs a little more.

[thedarkness]

Has anyone done the front arm mod to get more travel yet? I was thinking about doing it today since i blew my clutch bell bearings.Did you gain more downtravel when you did the mod?
Also has anyone tried the adjustable off-road clutch(centax)?If you did try it how much was it cost wise? and how good does it work?

[thedarkness]

i found an online shop that carries the gs SUT pro upgrades heres the link http://www.suzannegammage.com/products.php?id=68&pg=1
The SUT parts start at the 3rd page then they have the fioroni stuff after.They seem to be the only ones with the parts in stock

[nitrojunk]

Took the SUT out yesterday and broke in the Sirio .27 .. Boy does this thing rip, my only problem is as soon as I touch the stearing wheel to turn no matter what direction the opposite side front whell lifts and balloons like crazy..

[doesgo]

With that kind of power I can imagine! Have you filled your diffs? If so, you might want to consider sway bars, I believe they'll help.

[nitrojunk]

Yes i have 10,000 front, 30,000 Center and 3,000 rear.. Now i was driving on pavement so Im going to try it on the dirt this week..

I agree with the swaybars

[doesgo]

Just messin' around... :)

http://www.doesgo.com/rc/sutps1.jpg

[Monsterbrad]

Nice pic!
I love my storm its awesome.
Great performer in all aspects.
Mine is stock with the motor saver air filter and the stock Servo's from JR racing.
Super Truck.
Going to start some up grades here soon.
I was thinking about the full up grade kit for the truck to go pro with it. Anybody else done this yet>?????

[KrisP]

Where is the cheapest place to buy a SUT online?

[Monsterbrad]

Check with Speed Zone Raceway in TN.
Talk to mike and see what he can do for one of these trucks.
1-866-590-0763
I buy all my stuff from there he is a great person to deal with and knows about all the trucks and racing and all that.

[KrisP]

Thanks man. I will give him a call tommorrow.

[nitrojunk]

im selling mine if youd like.. tony.martins@bbh.com

Excellant condition with a Picco .26

[KrisP]

Nitrojunk ygm.

[RMG]

im selling mine if youd like.. tony.martins@bbh.com

Excellant condition with a Picco .26

Can I ask why you are selling your SUT?

I have been racing my Savage a few months now and am looking to move to an Unlimitied Class truck like the SUT. Is it a good truck, or are you having to many problems?

http://home.comcast.net/~pelletgunn/rage1.jpg

[nitrojunk]

Hey no problem.. Its a great truck, I also have a Savage and for what I do (BASH) the savage is better for me. But if you want to rip up dirt like nothing else this is the truck.. I have a Picco .26 in mine and let me tell you.. The forst time I raced my brother in law..he also has a savage with Fantom .27.. He took off first and I hit him so hard from behind I sent his Savage 3-4 feet in the air.. This thing will eat a 1/10 on road if they aint packing a Nice Italian Engine..

[RMG]

Thanks for the reply Nitrojunk, I'm thinking very seriously about the SUT as my next racer :)

[Monsterbrad]

Hello all
I have a GS SUT for SALE!!!!!!
I have 2 trucks the one is all parts and the other is almost ready to run.Needs a radio unless someone wants the traxxas radio I have, there are 2 engines and many extra parts.
This is great for racing because parts are hard to get for this truck.
Feel free to email me and or call me
ExExCR@aol.com
814-450-6973

[doesgo]

Why the sale, MonsterBrad? Based on all your posts in this thread, you really seem to love your SUT!

[Monsterbrad]

Well I do love the truck alot but I am going to move on.
I would like to sell it on here to someone that is going to race it or something like that.
I have 1 complete one and another one that has been used for parts.
They are going to go on ebay if nobody wants it off here.
I do love this truck alot but I have a Menace,LST,T-4,SUT and now a Revo.
Just to much for my little hobby area.
So the Sut is getting moved out as well as the Menace did.
Anybody interested.
I will send pics to anybody interested.

[vbgagnon]

How much do you want for them?

[Monsterbrad]

I am looking to get around 400.00 for everything.

[illbreakit]

Well, after 2 months of waiting, I finally recieved my SUT from Ebay. MAn, what a piece this thing is, I got took hard. $400 part's chassis is what I bought. Me sooo mad.

Anyway's, this person figured the SUT would work better with Integy Tmaxx shock's on it. Now, there buttery smooth, have the cool looking, but useless piggyback resevoir's. But most of all, there to short. reduces my travel bigtime. Is the SUT shock's standard 1/8 buggy rear leingth's? Just wondering so I can expand my search on ebay for other than just SUT/Storm.
Thx for the help, now anyone want a set of 4 Integy shock's LOL

[doesgo]

That sucks! Sorry to hear of your bad luck, illbreakit.

The SUT's shocks consist of four standard Storm rear shocks, as you suspected. From what I understand the best ones out there are off the Kyosho Kanai buggy. Storm shocks are okay, but not great.

[Monsterbrad]

Hey my truck is going to be for sale here soon!
350.00 for a rtr truck and a parts truck with many many parts.
XR3i radio with the servo's
Email me at ExExCR@aol.com
Somebody has to want this truck!!!!

[illbreakit]

Thx Doesgo, I think I'll get some OFNA shock's. My last buggy was a MBX Pro and the shock's weren't to bad on it, I allso have some spare rebuild stuff for them and there cheap on ebay. Alot better than $50 for 2 Kyosho shock's :o

[doesgo]

GS Racing takes two more wins! I posted basically this same info on the Storm buggy thread, but here goes...

Well, it's on my local track so it's not exactly national news, but I TQ'd and won the A Main with my SUT last weekend! Those were my second TQ and second win in the 2004 summer series which gave me the series championship in the Unlimited Monster Truck class!

Not only that, but after having engine problems in the qualifiers with my Storm buggy, I won the B Main, bumped to the A Main, and won that by four laps with my ultra-reliable GS Storm. Okay, okay, it was the Sportsman class, but my lap times were very competitive with those in the Pro class, so I'm fired up to move up to Pro next year with my Storm. In four series races this year I TQ'd three of them, won three of them, had one second-place finish, and won the series championship.

I sure do love my SUT and Storm! They've treated me very well for my first year of racing. :)

[illbreakit]

Right on!!!!

I finally got my SUT out in the dirt yesterday. And let me say, With a REALLY finicky WS7II, To short, under damped Tmax shock's, and steering and suspension component's that are all beat to heck, it handled great. Way better than I expected. I can't wait til my part's get off of backorder and get here, then I can build a serious rig :D

Oh well, I might as well paint a Elcamino body for it then while I amwaiting

[Monsterbrad]

Hey I have a parts truck you want to buy it?????

[doesgo]

I'm glad you're liking it, illbreakit! They're really fun to drive once you get it dialed in to the terrain and your driving style.

[illbreakit]

Monsterbrad, you have PM

[Monsterbrad]

I think around a 100 for the parts truck will be good.
Its a roller with no engine or anything.
Doesn't have tires or wheels either but has cv drive shafts all the way around difs are like new center dif radio tray stuff.
Its missing some of the steering parts.
I will throw in a pair of 9.5 Ofna shocks.

[illbreakit]

OK, was going through my truck, doing the 'raced out' mods that are on the GS site. I have TMaxx shocks on there right now, there to short. I noticed in the front though, there compressed at max suspension droop. The front aand rear use the same shock tower, right? I am totally unsure what this guy has done to this thing. I have deduced that he converted the buggy somehow. I don't know if he got thie kit, or just bought some pieces. If the front uses the same shock's as the rear, and the shock's I have on there now are to short for the rear. They are compressed about 1/8" I guess in the front. Is that normal? I have goten a bit more down travel in front, but I just wanted to make sure thing's aren't totally screwed up.
Man, last used thing I buy off Ebay, New or nothin now.

[Monsterbrad]

I know stock like mine still is ...
The shocks are the same thing.
I would say take the t-crap shocks off and get a pair of good 1/8 scale buggy shocks on there.
I have heard that the 9.5 ofna shocks fit also.
You have to be careful about ebay.
Things are not always what they are put up to be look carefully at the pics and make sure they have at least 95% or better feed back.
I bought a set of 9.5 shocks complete with springs for 35 bucks.
Had oil in them also.
Pretty much ready to bolt on.

Ya, I have a set of shock's coming, I was just wondering about the comppressed leingth at ride height of the front's to the rear's. But, on closer inspection, I see that the lower shock mounting holes are more inboard than the rear's. That will cause the added compression in the front that I was concerned about.

And as far as Ebay, I have been dealing on there for over 3 year's now. This is my first time at really being burned. I was shorted a $15 item once because Ebay acctually banned someone when I had a transaction in progress, and they never told me they were banning him :confused: . All, in All, Ebay isn't bad, but like you say, you have to research a little, I thought I did on this one, but the guy changed alot of stuff from AFTER the ebay add/picture was taken.

Ohh well, ya win some, you loose some. I am just tickled pink with my MACH 26 right now. I am in the process of testing a bunch of different pipes for it right now. I do haveone thing to state. I have one of GS's Silicone Exaust deflector ipe thing's, and with ALL pipe's I tested on the MACH, it LOVES to have the extender thing on. Like night and day performance difference with little to no temp change. The only explanation I can see is that the MACH 26 needs more backpressure than most other engine's. If you are runnig the 26, get one of these extender's, you won't be sorry. :) :D :cool:

[Monsterbrad]

Do you mean a stinger extension.
The thing that goes on the pipe tip the extends it out to deflect the oil and stuff normally.

[illbreakit]

Yup, that's exactly what I am talkin about
These

http://www.gsracing.com/gsracing/images/products/GS-P21BL.jpg

[Monsterbrad]

Hey what kinda dif did that tip make for performance????

[illbreakit]

With the RB 63 and OFNA Pirate pipe, alot of performance difference. With the RB pipe without the extender, it was like it was running 50-70 deg cooler in performance, but it was not running cooler. It acctually fell of when I was running it with the RB pipe and I was like "***, what happened? It would barely get moving, soulded like it got really rich, like the HSN just fell out or somehting. I kept it running, A bud found the extender and put it back on while it was running and instantainously I was back on the power. We were like "whoa, that's strange" That's what prodded me to test the concept even further with all 3 pipes I have.

On a side note, Here's a link to a vid I just made with me and a buds Savage at the local pit. My first vid so bear with it :D Ohh, it's at RC_pics.com so you'll have to delete the - from the URL to make it work. (it's the only place I know of to host it)

WOW.
I was going to sell it but I have so many extra parts I use this truck as an I'll try that truck before I try it with the REVO or LST.
Broke a fron a arm finally after extreme pounding.
I hope GS comes out with longer arms or something to get rid of the wheel extenders.
Like the new HB truggy has.
Looks like GS has there first bit of competition!!!!!!

[illbreakit]

Did I waste $80????? I just got my OFNA buggy rear shock's, assembled them and put them on the truck. Now, I think they are a mile to long.
What the heck is going on?

I thought all buggy shocks were the same leingth? :confused: :( This is really beginning to tick me off, about ready to sell the whole works and take a huge loss in $$$$$ :eek: Someone please help me :o

[illbreakit]

Them compressed

[Monsterbrad]

They look good the stockers are a little long also.
It doesn't matter what they look like before they go on the truck.
I run mine like that no problems.
I think that you are used to everything fitting good like on all other vehicles but this thing is different because its a truggy.
Just run it don't worry about the shocks.
I have the same shocks and run them with out a problem.

[Monsterbrad]

Ok I just went over a looked at the travel of the stock shock compared to the ofna one.
I would say change the bottom mount to the gs one that looks like that will bring the travel to where you want it.
Try that!
I hope I can help here.
Also with the travel limited I know it stinks but you will not slap the chassis as much either, i like mine the way it is.

[illbreakit]

Thx MB, I acctually made some shock tower extension's out of aluminum last night at work. I am gona try them, maybe refine them a little to incorporate the body mount lift kit I made. I had to lift the bost post's 1/2" to make my ElCamino body look good. If I get these tower extension's working/looking good, I be sure to post pics. I will also get a set of GS shock ends. I see now after you said that that they appear long there, and shorter ball ends might make it just right.

[Monsterbrad]

Sounds good ......
Take pics and lets see what those towers are like.
I am still in stock form with this truck.
Going to make it pro here eventually.

[erikderaaf]

has anyone tried proline 40-series tires and wheels on his sut yet??

[illbreakit]

I have a pair, never mounted them yet. I think I am going to sell them. The gearing would be to high IMO. If you could get a larger spur, then ok, but I am running a 12 tooth with a Mach .26 for hillclimbing. with the 13 tooth, even on the flat's I think it would smoke clutches pretty easily.

[illbreakit]

BTW, got some cool footage of me and my bud at the sand hill last weekend. It'll be alot better than the last movie I made. We cot a new capture card. Seem's the one we was usin was screwed, that's why the last vid was so blurry/choppy. Man, the SUT outclimbs the Savage too :D I locked the center diff with 2 small chunks of rags rolled up in the slaces between the gear's. Works great for climbing. My bud had to put paddle tires on the rear so he could have a chance at highmarking me LOL

[strechm]

I'm considering dropping a higher hp big block into my SUT. Without going out and breaking the bank on torsen diffs do you think that going to higher viscosity than 10,000wt in the front diff may help distibute the power better?

I currently have the stock .25 and for fun was thinking about dropping my Sirio .27 pro into it. The diff fluids now are 10,000 front, 30,000 center and 3,000wt rear. The 10,000wt fluid in the front diff is barely doing the job at this time with the stock engine. One of the local techs suggested I move up to as much as 30,000wt in the front.

I lack the experience with this one so any feedback will be appreciated.

[doesgo]

It only takes a few minutes to do the job, so.....why not try it?

[illbreakit]

You might want to up the center too, depending on what you are running on. If your bashing, I found 50,000 was the minimum for the center. That also works good for racing too. Especcially if you race in loose condition's. You could stiffen the front more, but remember, stiffening the front will let it pull harder exiting a corner, but push entering it, and thicker in the rear will turn better entering the corner and push exiting it. It's all abouit finding a ballance that you like, each driver is different.

[strechm]

I do not race and we bash on hard packed dirt this time of the year.

[illbreakit]

well then stiffening up the center is more what you want to do I would think. Try the 30 in front, 10 in rear and 50 or more in center

[Monsterbrad]

I have 100,000 in the center.
I was going to sell this truck but I am so glad that I didn't.
I had it out tonight for a few hours and man does this thing take a beating.
I was doing back flips and all kinds of high speed stuff hitting huge piles of dirt wide open and it just kept comming back for more.
This truck is AWESOME!!!!!!
Lost a front drive shaft broke the drive pins off by the out put yoke.
Other that bending the chassis again is still was going strong in three wheel mode.
Sweet
me and my buddy were laughing so hard I could hardly drive it.
Just aim for a pile of dirt and run it WOT right over it huge air and smashes back onto the ground.

[doesgo]

Ahhh, that's what I like to hear, MB! My racing season is over and I'm pretty fired up to do some bashing with my SUT! I've resisted all summer long, but not anymore... :)

[Monsterbrad]

Just make sure you up grade the steering arm.
That way you won't have that problems with that.
Have fun this thing is tough......

[doesgo]

The steering plate? If that's what you're talking about, I've got that triple-thick right now. No problems there.

[illbreakit]

OHH YA, I have some sand hill climbing footage that I'm makin into a vid. That SUT just shot up the hill, then, when I'd shoot to far into the lip, it would cartwheel all the way down. a good 40-50ft down :D AND, there is a few backflips 14ft off the ground in there. SOme, I never completed. But the only damage was a lost screw holding a front body mount and my air cleaner fell off from the hard tumble's. I made 2 climb's before I knew the cleaner was off :( Cleaned the motor on site, assembled and ran another 3 tanks. No noticeable loss in compression. It's a Mach .26 with a picco carb I run, awesome engine, totally reccomend.

I hope, if this weekend goes right, I should have a vid out by early next week, stay tuned, I'll post a link for sure.

PS, wa the steering plate, it's freakni weak. I carved a new one out of 1/4" alum(cheap alum I have at work) till my 7075 BB one get's in from Back order. It seem's beefy enough to hold, but hit's the upper hing pin holders a bit. Nothing serious though. I have some pics of my shock tower extensions I made, but need new camera batt's now. They piced a right time to go dead {mad**

[strechm]

Thanks for the info, I'll give it a try.

[xdamxincx]

can anyone tell me the fix for the gs stock shocks ?

[doesgo]

Uhhhh, what?

[strechm]

Are you guys breaking a lot of cva's. I am, three in the last 2 weeks. The strange part about it is that its happening while setting up the truck, not under bash/race conditions. I finally did a shiny ofna #36052 front cva mod and drilled the holes for the pins out enough to fit the stock setup then used spacers to keep rounded joint in from wearing on the bearing race (I belive that is what you call the inner part of the bearing). We shall see if this holds up.
http://www.lightninghobby.com/clients/lightninghobby/ecommerce/catalog/prodImg10134.jpg
In addition I have upped the front diff to 50k, center 100k, front shocks 80k, rear shocks 100k. Now it tracks as straight as an arrow on dirt and pavement.

[illbreakit]

Haven't broken an axle yet. Where are you breaking them? The dogbone, or CV end? What powerplant do you have in there? I am pretty brutal on mine, as you can see in the vid.

[strechm]

[QUOTE=strechm]front shocks 80k, rear shocks 100k.QUOTE]Correction, 80wt and 100wt respectfully. The shock oil wt had the consistancy of slightly thicker than water. After changing the weight the front diff unloading problem was corrected.

illbreakit,
I cannot get your vid to work....Three in a row. Two on the right and one on the left. The hobby shop wehere I had purchased the second set could not believe it either. I haven't hit anything. It appears that they were poorly made. We can see where there may have been bubbles or hollow spots in the metal when they were manufactured. Here is an exploded view of a set to give you an idea. The left hand side ball portion of the axle that houses the coupling broke.

Got it that time. Great vid. Bash em and trash em!

[Monsterbrad]

I thrashed mine so bad that the header got smashed when the chassis brace let go and the chassis go t bent up pretty bad in the back.
Still ran till I lost the front cvd then it was still running but hard to control.
I am also slipping the clutch alot kinda stinks but this thing is great for aim and full throttle jumping.

[doesgo]

I've only broken one CVA through an entire season of racing and some decent bashing. Sounds like maybe you did get a bad batch.

[illbreakit]

Man, weather has goten COLD. A severe snowfall warning has been issued:( Just all of a sudden. Hmm, I just watched Day After Tomorrow, wonder if that has anything to do with it LOL. Well, I guess it's time to go waterproof my SUT, get her ready for some snow action

[Monsterbrad]

I thought about the snow thing I think I am going to skip the SUT do to low chassis height.
The LST on the other hand thats going to get some snow action.
Maybe some new tires.

[illbreakit]

[extreme jealousy] Man, I wish I could have a SUT and a LST [/extreme jealosy]

[Monsterbrad]

I have to say that I had this truck out a few nights ago I tried to break it and I could not.
THis thing is just crazy.
Just shoot for the jumps a keep the throttle pegged back flips like crazy landing 5 foot up 40 foot long jumps just awesome.

[erikderaaf]

i like my sut very much, but there are two problems that I have with this car.
I've already wrecked two rear bumpers, thats more because of my bad jumping.

the other problem is that the metal hinge pin mounts on the chassis plate (sorry don't know the exact word, I'm dutch..) keep coming loose
i already treadlocked them, but eventually they come loose.
maybe a stronger type treadlock.

has anyone had this problems and found solutions?

[Truggy]

I was wondering, is the Pro Chassis longer than the rtr Chassis?
I have to say that I just love this damn truck, bought it for racing, but it bashes just as good....
Thanks for the help.

[illbreakit]

The hinge pin mount's should have screws that protrude through them enough to get a nut on the topside. I use a Nylock nut. I have never lost one, have broken them though LOL

No, the Pro chassis isn't longer, it's stronger and lighter :)

I am just about to recieve my brand new Taig CNC milling machine. What part's would you guy's like to see made for the SUT? I have some shock mount extender's on mine that allow full travel from OFNA 1/8 shocks. I'll be tooling those up for sure. OFNA shocks are really cheap and plentifull on Ebay, and I have never had a problem with them when I ran 1/8th, I used OFNA. I am also working on drawing a center diff mount that is 2 pieces, and 1/4" taller. Alowing for better motor placement and yo don't have to take the bottom screws out, just pull the top plate and lift the diff out. I could also adapt the mount's to fit any 1/8th style center out there. Like, umm, a 2 speed :) Just idea's I'm toying with. I'll also be doing Savage part's, but that's for another thread LOL

[Truggy]

OK, thats what I thought.
I just got both of my PRO Shock towers, the look sweet, strong too lol.
Is there a steering upgrade for that week stock steering plate or arm..?
I would guess that they make rear aluminum hub carriers?? I can use em..

[thedarkness]

double or even triple stack the stock steering plate for more durability

[Truggy]

Ok, now what about the rear Hub carriers. Is there an upgrade out there...

[thedarkness]

If there is a hop up youll find it at www.gsracing.com. Look under fioroni they make very high quality parts, but are expensive as they are imported from italy

[Truggy]

Hmm, dont see any. But thanks for the help.

[doesgo]

Hmm, dont see any. But thanks for the help.

Fioroni does make SUT (Storm) rear hub carriers, I've got a pair. They call them rear knuckles, part number OT-GS07, $93/pair.

[doesgo]

I've taken to bashing my SUT now that the racing season is over and loving it! I pulled off a triple backflip with it this past weekend, the video should be up shortly. I'll post a link when it is.

[illbreakit]

A tripple, Man. I'm jealous. I managed to squeek a double outa mine, but a tripple Sweet. They are great for bashin though. Lock the center diff, too. I put 120000Wt in there, wasn't enough. Cut some squares out of a old rag, and layed them on the side gear's. above and below the 4 spider gear's. Seel's to be holding up well. Awesome for climbing then, and does 4wheel drift's well :D

Gonna be taking some more footage this weekend, so I'll have a vid up soon myself.

[Truggy]

Great thanks, I will look for them again.
Damn a triple..SWEET!

I'm down right now myself, waiting for Pro Line to send me new 40 series Volec wheels.
The hex stripped out of 2 of them the first time out, they are replacing the rims and my bowties too...

[thedarkness]

I just seen the vid.That last rotation just snapped around.Good job doesgo.I noticed you were running the stock body, is the carrot body dead?Keep up the good work.

[Truggy]

Wheres the vid link???

[doesgo]

http://www.slapmafro.com/images/backwoods-poster.jpg
Please right-click here (http://www.slapmafro.com/movies/SMF-BackwoodsBash.wmv), then save to your computer.

Thanks thedarkness. Yeah, the rotations came faster and faster! The carrot body isn't quite dead, but doing the jumping did a number on it, it's getting pretty cracked up. Hadn't run the stock body since about the second tank of fuel went through the truck last winter so I ran that body for a change this past weekend. But for jumping I'll stick with the thick carrot body until it's dead.

[illbreakit]

Cool Doesgo!!! Tripple backflip. Man, now I gota go for 4 for my vid LOL I just got the GS part's I have been paitently waiting for for month's. BB 7075 steering plate, Brake pads, and diff part's. Just takin a brake from putting her together. Gonna lay a smackdown on a REVO and S-Maxx this Sat. We figure the REVO driver will be out first, so he'll run the camera for the rest of the day LOL

Illbreakit
Screwed Up Productionz

[doesgo]

Go for four, man! If I had more motor I think I could do it, but I'm still running an O.S. .21 RG in mine. Nice little engine, but not a total screamer.

Good luck this weekend.

[illbreakit]

That's the RG, wow impressive. I was going to get one of those, but settled on the Mach.26 instead. :D

[Truggy]

What other bodies will cover the sides like the stock one, and look good?

[doesgo]

Yeah, I didn't expect this much out of the RG, that's for sure. It's getting old, too. I bought it in August of 2003 for my Savage and must have 4-5 gallons on it. Super reliable, too.

My SMF cohort has a Mach 26 in his Savage and is liking it pretty well. You like yours, right?

[doesgo]

I can't tell you much on bodies, Truggy. I've only tried the old Chevy pickup body and the stock body on mine. Bodies designed for T-Maxxes and Savages are supposed to fit, but not if they're pre-cut. The engine, fuel tank, and body posts are all in the wrong spots.

[illbreakit]

I can't say for bodies either, I run a HPI ElCamino, it's a little long, and had to raisw the body post's up to make it look good.

Ya, I like my Mach.26. I put a Composite carb from a Picco X21 onroad on it though. That carb really woke it up. Tell your friend, if he hasn't goten a different carb yet to look for one. I also ported mine. The engine responded well to that too. I have porting job's for sale occasionaly on ebay, but if anyone's interested, drop me an PM.

[illbreakit]

OK, SUT all suited up, ready to lay some down on Traxxas :D
One thing tho that ticked me off. I got mine used, the previous owner passed a converted buggy off as a SUT. So I was stuck with stock 1/8 hexes. I ordered the Pro axle extender's. Got them on Friday after 2 month's waiting. There's no pin's or the long setscrew :mad I had to fabricate my own. I plan on running Panther paddles today and there on MT rim's, I needed the extenders.
Well, after I got the pin's to fit etc, I noticed that the extender's acctuallt sat about 1mm ou from the bearing. This caused alot of play/axle slop. I cut thin slivers of fuel tubing to space it out for today. I'll have to make some metal shim's next week I guess. Are all your extender's like this? I got new pro CVD's all the way around????
Just curious.

[Monsterbrad]

There is some play in the axles but not a major amount.
My truck has been beat pretty good so there is a bit of slop but it still runs great.

[Monsterbrad]

HEy anybody want to buy a SUT with tons of spare parts?????
I have one well almost 2 trucks

Thought you was gona keep them? After you realized how well they jump

[Monsterbrad]

Well the new Hot Bodies truck jumps better....
PLus I do hate to get rid of this truck just cause its so reliable but this on and the revo are going.....
They are both going to be on ebay after next week if they don't sell at the track next sunday!!!!!!
Don't get me wrong people this is a great truck I just have to many at this time.....

[maxmod]

hey guys
i just built my sut pro the other day and i didn't haave any 30k diff oil so i just went with my usual buggy setup of 5k front 7k centre 3k rear what the benifit of running 30k in the centre and 10k up front.
also i want to remove the wheel extenders and put normal buggy hexs on and get some dominator wheels is it that easy.
i am thinking i will get the fironi chasis as i need alot more droop in the front.
and some mp777 sp1 rear shocks all round.
i am going to put on a wing and remove the sut bumpers and replace them with the buggy ones.
anything else that i should do it will be pure racing truck.
also what about sway bars and shock oils.
i am running a rody c5 with a fironi turbo slider at the moment but i should have a os v-zb v-spec in there soon.

[thedarkness]

Wow sut pro must be nice.With a thicker center oil the diff will put power to the front and back more evenly and wont unload to the front.For the wheel adapters use buggy hexes and use ofna offset dominator wheels.I found for shock oild 50wt in the front and 45 in the rear.

[maxmod]

thanks yeh the sut pro is a great truck.
i want to make is a race beast and also today i am going to try and put my mbx-5 cvd's in there and if they work i am getting hyper 7 universals.

thanks for clearing the reason u use such high diff oils for me i am going to also use panther lp komodos i run komods on my buggy so i now they have great grip but i heard the make it handle better in the air.

do any of you guys have msn as i would like to discuss the sut more i have no real experience with mt's i have had a savage but it was crap and sold it before i even went through a litre of fuel.
my msn is lachlan_r1990@hotmail.com
i would love to talk to you guys more

[Monsterbrad]

Come on guys !!!!!!!
One of you readers out there needs one of these trucks..
I have one RTR with the xr3i and a complete well almost complete parts truck also.....

or ExExCR@aol.com

[maxmod]

hey monsterbrad can u try and put the hb arms and stuff on ur sut i want to try it but since u have both can u see if it will work without to many mods.
thanks

[Monsterbrad]

It does not look like that will work but I am selling the entire rig so I don't want to mess with that sorry.
The arms are different in the middle.
The stock mounts will not work as far as I can see...
The Hot bodies stuff might work if you change to all HB mounts and that...
If you go that far just buy the Hot Bodies truck instead...
Anybody want a SUT
I have a sweet deal!!!!
RTR with xr3i radio and tons of extra's
$350.00

I really, really, really wish I could, MB! I love my SUT and my Storm and having another on hand with tons of spare parts sounds great to me, but alas, somehow my wife doesn't agree! :(

[strechm]

So do I MB, that's a great buy. I'd make you an offer just to have all of the parts along with a 2nd truck but I'm currently building 2 1/18th scales, a Mini T and RC18T(on order) with a Mamba 6800 brushless, 3 cell lipos along with all of the critical upgrades. A small fortune but what the heck. Put up some threads in all of the forums on XMas day. You'll may be suprised how quick they will move. The XMas cash always gets spent quickly.

[Monsterbrad]

I'll take 50 bucks off for ya...
tell your wife that its a 600 dollar truck and you are getting basically 2 for 300 bucks..
I have pics comming tonight or tomorrow...
Plus you get a great radio tooo

[Nitro Quad]

Hi my name's Jerrod. I've been following this thread for some time now, and I finally broke down and bought a storm sut. I would love to go run my new truck, but it's freezing cold outside and since I live in Wyoming it'll probably be that way for a long time. So I was wondering if you guys can help me out with some general things like, shock oils, differential lubricant and other things that will help me get a jump on next season. I'm not completely new to this but I am a quadriplegic and that makes even easy things difficult and time-consuming.

I don't have any immediate plans to race my truck as we don't have a track here in Cheyenne. So she will mostly be a basher but with any luck, we may have a track built by next summer. Thanks for any help.

[doesgo]

Check out Garen's write-up on how to set up an SUT, it's excellent. Since you're a basher rather than racer I'd just go through the basics and use the guide for shock oil and diff lube and other such things rather than measuring droop and whatnot. But it's still interesting reading.

Go here: http://www.gsracing.com/web/page.asp?pgs=downloads and then click on the "How to race-tune your SUT" or something like that. It seems to be down right now but will hopefully be back up soon. If not, I could send you a copy in Word format.

There are a few other things the SUT should have for good racing or bashing use/abuse and I've written up what I suggest for a couple other people and saved it as a text file, but I don't have a copy at home. Shoot me an e-mail if you want it, I can send it to you tomorrow: doesgo@slapmafro.com

Have fun with your SUT!

[Nitro Quad]

Thanks man, I appreciate any information I can get, but I'm still really new to this e-mail stuff, and I have no idea how to use the Wizard thingy to e-mail you directly. So would you please e-mail me at jguerney@bresnan.net sorry for my ignorance, my girlfriend is trying to teach me, but I'm a slow learner. Before I got hurt, I was off-road mechanic and I never had the use a computer.

By the way, you guys have a great web site. I've downloaded several of your videos, and my three-year-old son won't go to bed at night, unless he gets to watch one or two.

Thanks again.

[doesgo]

Thanks for the kind words, Jerrod! I'm glad you and your son like the videos. We sure enjoy making them!

By the way, you've got e-mail.

[Nitro Quad]

Thanks for all the information that should keep me busy for a while. I also want to put an in-line fuel filter on my truck but I'm not sure which one to choose. I have a sirio 18 in my TMaxx and all summer long it bogged out at full throttle I finally discovered the fuel filter was restricting the flow and I don't want to make that mistake again. So if anybody has any ideas drop a line.

Thanks.

[doesgo]

Any R/C car fuel filter will work fine. Most of mine are from Dubro.

[Monsterbrad]

Hey guys I have pics of the SUT...
ANybody interested ?????
For Sale Still

[Nitro Quad]

Wow, this forum guy really quiet. I guess it must be the weather, because it sure is cold here, which is driving me nuts because I have a brand-new SUT and I can't drive it. Although yesterday I found something that'll break up the winter monotony. Most of you guys probably know about it, but it's just so cool I had to tell you guys anyway. It's a web site called virtualrc.com.

Basically, what it is is an RC videogame, but you get to choose the cars that you race, and you can customize and tune your car just like you would in the real world, and then as if that weren't enough, you can use your own radio equipment by purchasing a special USB adapter. Now before you start sending me hate mail, there are no monster trucks, and you have to drive touring cars, but you get to compete on real tracks and even race people online. I don't know all the specs on the equipment you need to run the game. But go and check it out. It's really COOL!

[illbreakit]

Hey, I've been waiting for that to be ready. I'll have to go check it out after new year's.

Oh, BTW, I am getting pretty proficient with my new CNC milling maching :D Got some SUT part's that will be ready soon. Some diff spool's, new shock towers that will use the ready availible and cheaper OFNA shock's and increases availible shock travel. Stay tuned for more info.

[Monsterbrad]

Come on somebody has to want these trucks I have here
I sold the revo
FOR SALE
2 trucks
one rtr and the other parts
many many extra's

[stonesavage]

I have just completed my sut pro what an awesome kit.added the fironi rear bulkhead brace{a must for storms]m8 radio novarossi 28.this truck is insane it will eat my monster gt racer for breakfast i never thought a monster truck could handle so well if your into racing trucks get an sut pro you will not regret it.

[Monsterbrad]

or try the LSP
its better yet

[stonesavage]

anyone know if the front of the sut should bottom out or not mine will not bottomout any way i set it up the rear works great.and will this affect the overall durability like bent tower broken arms. :cool:

[doesgo]

Yes, it will bottom out just like 1/8-scale buggies.

[stonesavage]

It is fact that gsracing is now testing longer arms for us sut racers i saw a pair there kinda like the hot bod lsp arms not sure when they will be ready for shipment hopefully summer2005.

[Monsterbrad]

I have had both this truck and the LSP and I have to say that this truck is really really tough probably the toughest truck I have ever owned besides the Savage.
The LSP on the other hand I feel is a little bit better of a racer than this truck but with longer arms and a longer wheel base there might be some competition.....

[Nitro Quad]

Monsterbrad-what's the LSP I've heard of the LST, but not the LSP. Just curious.

I was hoping you guys could settle something for me. I'd like to take the pull starter off my RM 25 and go to some sort of shaft starter but, I don't know who the original manufacturer of the RM 25 is. The only thing I've been able to find out is that it's possibly an XTM 24.7. I know I could just call GS directly but I thought I would see if you guys know anything first.

Thanks.

[doesgo]

The LSP is a Hot Bodies Lightning Stadium Pro.

The GS R25MT is built by SH Engines, which also makes XTM engines. The Roto-Start that comes on a Savage will work, as will the starter unit offered by OFNA. OFNA sells them with the starter shaft socket in a couple different places, but the Savage version worked fine for me on my SUT.

[Monsterbrad]

Pul starts do suck..
and with all this new starter system stuff comming out and what already is out there will be no need for the pull start anymore....
I did like the engine in this truck it was a rock solid performer!!!!
Just did not have the power that others do...

[stonesavage]

Warning if you take off the pull start make shure to use a spacer in the roto starts back plate or you'll kill the one way bearing and mabey your engine I learned the hard way(only for engine's with internal one way's) :)

[doesgo]

Good call, stonesavage. OFNA makes the necessary spacer and includes it with their 24.7 starter unit.

Hey guys i'm new here and was curious to how true it is about GS going to release a set of longer A-Arms. I love my SUT and that would make it alot better. I just put a Sirio .27 in it and I can't wait to take it to the track! I have been looking at the HB Stadium and it is sweet but, If they are going to come out with the longer arms I can stop looking at that Lightning Pro!

Thanks!

[Nitro Quad]

Thanks guys, I've got a starter box, but it's set up for my TC3 and I don't want to move the pegs around. I know, I'm lazy, but those shaft starters are so COOL :cool:.

100%truth also an extended chassis is being tested{HI-TORQUE'S R/C CAR] magazine feb2005 has photo's :)

That's awsome man I can't wait till They come out! That will make a huge difference in the SUT. I really like the car know I could imagine it with these new additions! Thanks for the info!!!!!!!!!!

[doesgo]

Can someone explain these lower arm mounting blocks to me? I know they have different angles for different anti-squat and kick-up, but the labeling has me completely confused.

The plastic ones (Storm RTR) are labeled "1" or "2".
The cast aluminum ones (SUT RTR) are labeled "A1", "A2", "B1", or "B2".
The billet aluminum Pro ones are labeled simply "A" or "B".

How the heck do I select which ones to use front and rear and left and right on my SUT and Storm buggy?

[jmangler1]

Got me their! I could use that info also! Can be a big help with setting my SUT up!

[jmangler1]

any idea when the extended chassis/ a-arms are comming out?

[doesgo]

Hopefully around the same time extended CVA shafts, dogbones, and upper links come out. :)

[jmangler1]

Yeh that would be nice huh! I dont know if I can wait I might sell the SUT and get the LSP!

[Monsterbrad]

the LSP stock will run the pants off this truck.
The only thing I can say about this truck is that its really really tough with the right stuff done to it.
I had one and pounded it like slap ma fro does there rides.
It was AWESOME!!!!!

[doesgo]

Why is the LSP so much better on the track than the SUT?

[jmangler1]

Well the longers chassis will definately help! I have a MGT and I drove a T-maxx and a savage and the MGT handles alot better the both of them being it is alitttle longer. Its alot smoother through the rough stuff!

Also on the LSP it looks like the shock are on more of a angle horizontle angle and the GS SUT Pro is more Virtical. I wonder if that make a difference. Even with those 2 things I don't think their is that much of a difference with the 2 trucks. I would imagine that the SUT is lighter so I would give the speed to the SUT, but l then again I never drove the truck(LSP). The stock motor that comes with the SUT kicks butt
from what I hear. I never used mine still brand new I never even broke it in I had a Sirio .27 that went in immediatly and I must say that this motor makes so seriuos power! Alot of people dislike the SUT because of those cheesy wheel adapters, but other then that the truck is rock solid and fast as hell! It destroys my MGT in pure acceleration! I just dont see the much of a difference for people to be putting the SUT down and sayin It will distroy it.

[doesgo]

Thanks, jmangler.

I agree about the wheel adapters too. They look cheesy, but I've never had any reliability issues with them at all!

Either way, I like my SUT and I can't afford an LSP, so I guess there's no decision for me to make! :)

[stonesavage]

THIS APPLY"S TO THE RTR AND SUT PRO i spoke to a rep at gsracing and he told me both factory sut driver's use medium shocks up front to increase bottoming out that is what the chassis is designed for right!you want the bottom to take the force not the shock and or tower's I have just done this to my sut and what a HUGE differance it's work's Like it should have in the first place O well by the way the staff at gs racing are AWESOME first class all the way if any off you have had to deal with ofna you know how crappy some of these company's can be!and by the way longer arm's and chassis due summer05 as per gsrep.part#gs-25074medium shock bodies.gs-25071medium shafts.peace :D

[doesgo]

The medium shocks are the same as off the front of the Storm buggy, right?

[stonesavage]

I Have Had My Savage For Bout 2 Years It"s Totally In Race Mode Lite As It Can Get Werks Picco26 Tough As Hell Raced Last Summer 20) Or So Mains Broke Twice Minor **** Monster Gt Broke A Dozen Or So My Buddy"s gs Storm Pro With Monster Conversion Never Broke All Season No Bs That's Why I Got My Sut Pro Only Drivin Mine A Couple Of Time's On the Track But I Can Tell thatThis Truck Is Tough Handles Incredable Crazy Fast Lap Times Anyone Who Bad Mouth"s The Sut Does Not No What There Talkin About.ps After Today's Run Are Local Hobby Store Owner Is Ordering 3 Sut Pro"s One For Himself>long Live The sut.

[stonesavage]

The medium shocks are the same as off the front of the Storm buggy, right?
NO!those shock's are small the rear are large and these are medium they are atotal must trust me on this other wise you will blow your front shock's and bend the tower /crack front arm ect..these medium shock's are fairly knew to fix the problem with the sut not bottoming out up front.a little inside info.peace :)

[jmangler1]

Stonesavage, thanks for that info on the chassis&shocks! I have kanai 2 rear shocks all the way around on my SUT Pro I guess I should give those medium shocks a try and see how they compare. Anything to help out with handling!

doesgo, Dont you have a Storm Bug also? If so I just want to see what you think of the new Avenger Storm MK2? I would like to add a bug to my collection!

[doesgo]

Yeah, thanks stonesavage!

I do have a Storm RTR, jmangler1. I had GREAT luck with it last year after a few minor hop-ups to fix the weak steering plate and thin shock piston shims it made it through the entire race season with flying colors. My first year of racing and I took first place for the entire season series with it. In four races I TQ'd three times and took first place three times. Granted it was in the Sportsman class, but my RTR was posting lap times that would have put me in the top 5 in the Pro class, too. Needless to say I really love my Storm! Ultra reliable.

As for the Avenger....I liked what I saw at the iHobby Expo last October. They had one there and it was quite interesting. Not just the same old plastic texture revisions that so often seem to be the case. Will it work? I just don't have enough experience with buggies to really know what might work and what won't. I'd surely love to try one out sometime, but I'm enjoying my Storm so much right now I can't justify buying a new Avenger just because it's new. The Avenger definitely addresses some of the Storm's weak points, which is good, but how well it really works remains to be seen.

[jmangler1]

Cool Thanks!

very nice huh.the extended chassis will be out very soon like 2 months max.sooner that's just the latest date native will have one also gsracing is testing one for production(almost 2 inches longer as per gs rep) this truck is going to be un beatable. i love my **** sorry sut. :cool:

[jmangler1]

Yes it will be unstoppable!

[stonesavage]

come on guys post let's keep this #1 like the truck :)

[jmangler1]

I hear you stonesavage, I enoy when people are posting!

I have a question for you on the SUT. I never had a truck that has a metal spur gear before,are the generally noisey? I seems to make a little like tinging sound when I roll it back then forward.

[doesgo]

No, you really don't even notice any extra noise over the exhaust sound.

[stonesavage]

I hear you stonesavage, I enoy when people are posting!

I have a question for you on the SUT. I never had a truck that has a metal spur gear before,are the generally noisey? I seems to make a little like tinging sound when I roll it back then forward. HOW's your gear mesh ie.any ware on teeth /YOU should be able to hold the cb and rock the spur just a( Little) almost zero play a little noise is common on a metal to metal drivetrain. ;)

[Monsterbrad]

So any of you guys have this truck done up with the long chassis and arms????????
Lets see pics

[jmangler1]

Ok I took a closer look and their is a little wear on my cluth bell. I guess it will be time for a new one soon.

I'm going to order the suspension soon as work picks up again. We just got hit with some heavy snow over here in New Jersey and I haven't worked since. I will post pic's when I get it done!

[Nitro Quad]

I'm not sure how true this is, but I was always told to use a plastic spur gear. That way, you only ruin a cheap piece of plastic, instead of the transmission or the entire driveline if anything ever moves around or gets stuck.

[doesgo]

Depends on the vehicle, Nitro. Virtually all 1/8-scale buggies and truggies use metal spur gears with no problems. As long as you set things up right and do even minimal maintenance you should be fine.

I agree that steel spurs aren't always necessary in most vehicles, but they usually don't cause any undue harm.

hey jmangler why do you wana sell such a sweet racer in a month or so the extended chassis will be out plus tons of new parts from gs.by far this is the toughest and fastest truck i have ever owned and i work at a hobby shop so you no that i :) own several trucks.

[stonesavage]

I have to say that I had this truck out a few nights ago I tried to break it and I could not.
THis thing is just crazy.
Just shoot for the jumps a keep the throttle pegged back flips like crazy landing 5 foot up 40 foot long jumps just awesome.
THIS GUY WAS PRETTY HARD ON HIS SUT RTR AND SAY"S IT"S ONE OF THE TOUGHEST TRUCKS HE HAS OWNED!

[jimmimaxx]

Check out the long arm conversion for the SUT from Native Racing.This is the answer to the best handling storm. www.remotecontrolhobby.com

[jmangler1]

Well this is one of two storms that I have! I would like to sell this one and get a LSP or a LST! I don't need 3 trucks sittlng around! It is a great truck. I had a Picco Werks .26 in it and absolutly ripped!

[stonesavage]

Spoke to a gs rep today about the new chassis ''he said it will be a little longer than the LSP'' and will be out real soon :D p.s this truck with the x tended/and native arm kit ''forgetbout it'' i will be kickin the wife out of bed and sleeping with my sut.

[jimmimaxx]

Heard the exact same thing myself today.Cant wait.

[jmangler1]

hey guys,
I was looking at a LSP today and it looked like the shocks are on more of a angle then the SUT is, do you think that it will work better like that? Also will the shock angle change with the tomahawk suspension?

[stonesavage]

hey guys,
I was looking at a LSP today and it looked like the shocks are on more of a angle then the SUT is, do you think that it will work better like that? Also will the shock angle change with the tomahawk suspension?
The tomahawk kit will allow many! more shock positions allowing the storm to bottom out up front n rear without having to purchase medium shocks for the front. shock angle on the sut and most jt hybrids are set up that way for a reason/to crazy of an angle and your shock shafts will be more likely to bend.I set up my sut just like garren's and this truck is crazy!!fastest lap times ever/only complaint is it's a little twichy in the rough ;But the new x=tended chassis will fix that! Out of the dozen or so trucks I have raced The sut pro wins hands down.LONG LIVE THE SUT!! :D

[rgross]

stonesavage,

I recently bought a used SUT RTR and want to set it up for my local track which is a small tight track, very bumby/rutty, and one large triple jump, not much straight section.

You said you have your truck set up like garren's, what exactly have you done to the truck?

I am looking at the tomahawk suspension, and I am wondering if the extended chassis is really going to come out. What should I do to my truck to match your setup, and is your track setup any thing like mine....http://www.dirtrunners.com/Gallery_Workdays04.html

Thanks for any help that you could give me.

rgross

[Nitro Quad]

Congratulations! you bought a great truck. I can't really help you with stonesavage, personal setup, but if you go to gsracing.com and select the FAQ there's tons of information on how to set your truck up. I don't want to put him on the spot, but doesgo sent me a lot of information that got me going on the right path without a lot of trial and error. I'm sure he would help you out if you ask.

Good Luck.

[rgross]

Well, Doesgo, do you think you could help me at all. I would really appreciate it. As you can see from my earlier post, my track is no where as large or fast as fisk farm.

By the way, I love the www.slapmafro.com I have been watching the vids when you were mostly bashing, then I thought it was awesome when you went to the farm to start racing and filming vids there. It inspired me to race at my local track. Thanks

If you don't want to post it here and it's easier for you, then you can use my email....rgross98@hotmail.com

rgross

[doesgo]

Thanks for the SMF support, rgross! We definitely had a great time racing last year and look forward to 2005!

Here's what I put together for people asking me about eliminating the weak points of the SUT RTR. I thought I also had Marty Korn's truck's specs on file, but I can't find it. Must be on my work computer. I've also got the Word document version of Garen's full SUT write-up on race-tuning your SUT on file, I can send that to you if you want. It's about 550Kb in size. If you want that, e-mail me at doesgo@slapmafro.com.


The things I've done to mine and recommend you do to yours, assuming it's a stock RTR, are as follows:

1) Get the Storm Pro/SUT Pro steering plate (#GSCSTP04) or get another RTR plate (#GSCST035) and stack two together. The stock single RTR plate is too weak and will bend after a couple nose-down landings. I made two out of some scrap aluminum I had so mine is basically triple-thick. You'll need to countersink the holes and use flat-head screws to clear the upper arm hinge pin holder. The Pro plate (with bearings) is around $23, an RTR plate is $8.

2) Buy a 20-pack of 4mm x 20mm flat-head hex-drive grade 10.9 screws and use them to replace all of the stock lower arm mount screws. I've sheared the heads off at least six stock mount screws, but since I replaced them all with these screws I mentioned I've had ZERO problems. Do this ASAP, too, because the longer you wait and the more screws you bend or break, the harder it is on your chassis. $4-$5 for a 20-pack of screws. I've got one extra pack of 20 screws, let me know if you want it.

3) Buy two Yokomo diff thrust bearing sets (ZS-507, I got mine direct from Yokomo) and use the washers (two washers per kit) to replace the thin shims under the pistons in the shocks. The stock shims are way too thin and WILL bend and slide down the shaft allowing the piston to do the same, which means there's no shock absorption. I'd also suggest buying a GS shock rebuild kit (comes with o-rings and bladders) (GSCSH8) and some extra shock pistons (GSC10063), I've torn shock bladders and broken one piston so far, so it's nice to have the spares on hand. The repair kit bladders seem thicker than the RTR bladders for some reason, too. I think I've torn three RTR bladders but since I replaced those particular ones with rebuild kit bladders, I don't think I've had any problems with the kit bladders at all.

The Yokomo kits are about $3/each, the shock repair kits are around $3/kit. Not sure on the pistons, I haven't bought any of those yet.

Another option for the shocks is to just buy Kyosho or OFNA buggy shocks. Kyoshos are spendy, around $100 per set, but the OFNAs are cheaper I believe. I think they're pretty much a direct bolt-on but I don't think they'll go to full extension with the SUT shock towers.

4) I'd strongly suggest shimming the stock servo saver spring to make it tighter. It's too weak stock. I used a nylon washer that's about 1/8" thick, maybe slightly thicker. You have to take apart the steering to do it, so while you're in there replace the steering post bushings with bearings, I think they're 6mm x 10mm. An alternative to adding a washer to stiffen the servo saver spring is to buy the Pro servo saver setup. It's like a threaded shock, you just turn the knurled ring to adjust the tension.

5) Electronics-wise, if you got the JR stuff you're probably okay. If it's the GS stuff, you might want to be prepared to upgrade the servos. They're not bad as far as power and speed, decent for RTR, but mine didn't last too long.

6) Be sure to Loctite everything as with any car. I found most things Loctited on mine, including the steering post screws, engine-mount screws, but I don't believe the king pin screws (vertical screws that hold the steering knuckles in place) were Loctited. Make sure you Loctite those and put them in snugly, but only put the Loctite on the screw threads, don't get any on the bushings! I've had 2-3 screws come out so far, a couple even with Loctite!

7) Remove the body mount post screws and drill through the mounts and install long screws that go all the way through and put nuts on the ends.

That's about it for durability and such. I've had one front CVA cross pin come loose and have broken a couple rear axle dogbones (one sheared pin and one pin slid out), but that's through an entire season of racing and some pretty good bashing and jumping as well. I'd try to have a couple spare front c-hubs on hand as well as rear dogbones, and if you can buy a set of shocks for cheap off eBay, get them. It's nice to have spares just in case. I managed to score a full set for $12 one time!

As for sources for parts, Horizon Hobby has the most and Stormer Hobbies has quite a bit as well, but I get most of my replacement parts off eBay from guys parting out brand-new RTRs. Definitely cheaper than buying new if keep your eyes out for the best deals.

Slap Ma Fro! is planning to have a couple SUT hopups coming out in early spring, too. Can't say much about them now, but keep your eyes open...

[rgross]

Thank you Doesgo for all your help and time....that must have taken awhile to type. I know I appreciate it, and others will too. I also sent you a short email.
Over the next couple months, I let you know how it's going.

rgross

[doesgo]

No problem. Definitely keep us posted!

[Nitro Quad]

I've addressed most of the issues that doesgo listed above, and I've got my engine broken in and making good power, but I still want more. I know gearing is the way to go, but for now I like to find a good pipe to match the power curve of my R25MT. I still don't know much about these engines, but I do know the right pipe makes all the difference. So if anybody has any suggestions or opinions I would love to hear them.

Thanks.

[thedarkness]

I would go with either a fantom steel pipe or an RB086(or one of its ofna ripoffs).

[gotspeed_2000]

You might want to consider the Ofna Jammin JP1 pipe for added torque, or the JP2 for more revs. These are great pipes and I'm running one in my buggy. The stinger is reinforced so there is less chance of it bending and the metal thickness seems to be fairly thick so it's also strong. Good luck

[Nitro Quad]

Thanks Got speed, I've been leaning towards the JP-1. Although I've heard they dent real easily have you found this to be true or not?

[gotspeed_2000]

Thanks Got speed, I've been leaning towards the JP-1. Although I've heard they dent real easily have you found this to be true or not?


Actually, I've found the exact opposite to be true. These pipes are a bit heavier and that's because the wall of the pipe are thicker. Plus the stinger area is highly reinforced so it would resist pushing in even more than conventional pipes. The JP1 pipe is more for torque, but with the bigger displacement engine you plan on running, you might want to consider the JP2 to let your engine breathe better and allow your engine to stretch it's feet more. Between the two pipes, you really can't go wrong, but I would recommend you get the hard coated versions. It's better at keeping clean and I think it looks better than a polished pipe. Good luck.

[Nitro Quad]

It's starting to sound like I might have two pipes in my future. I like the characteristics of both pipes and the more I find out about them, the more I want both of them. :D

There's so many toys and just not enough time to play with them all.

[stonesavage]

These engines are the same as xtm 24/7 pro there both made by sh engines.

[thedarkness]

These engines are the same as xtm 24/7 pro there both made by sh engines.
Essentually your right but the porting is a little diffrent GS uses the sh.25 they just put there head on it while the xtm has allitle bit differnt porting on the sleeve.The gs engine is tuned for a more agressive bottom end while the xtm .247pro is tune more mid to high rpm.These have just been my observations using the same clutch on both.

[Nitro Quad]

So what you're saying is the GS version has a little bit more bottom end power than the standard XTM version? I know this all sounds a little silly when you can just replace it with an RB and have a rocket. Except I can't afford an RB 21 right now, but believe me, it's on my list.

BTW. It's good to see this thread is starting to come back to life. Personally I think GS did a good job marrying a buggy and a truck. Hopefully it will stand the test of time like the Tmaxx or the Savage has.

[doesgo]

According to an SH Engines guy, they're the same engine but for the head and the labeling on the side of the case. I've never had the two engines apart to compare them personally, however. As for the characteristics of each....tough call. As inconsistent as 2-stroke R/C engines can be, I wouldn't be surprised if you took two 24.7 Pros side-by-side and had one with a stronger bottom end and one that screamed more on top. You just never know, unfortunately.

NitroQuad, we're talking about the 24.7 Pro vs the R25MT, not the standard 24.7.

BTW, I just got my R25MT back from the pinching man, can't wait to drop it in something and DRIVE!!!

[Nitro Quad]

Sorry, my bad. Sometimes I get excited and miss small details. I hope you enjoy the R25MT. I finally got mine broken in, and it's AWESOME! :eek: :D .

[doesgo]

Very interesting! So much for my trust in the SH guy! Thanks for posting that.

[Nitro Quad]

I'm probably getting annoying to some of the old salts around here, but can someone break those pictures down for me? It looks like to me, the only difference is the porting and the polishing. Is that correct? If so, what are the advantages of the different porting and polishing techniques?

[thedarkness]

the diffrences there are 3 types of port conifguration in there 5 port engines.
The gs has its transfer ports so the front 2 are open at TDC but not the 2 closest to the exauhst port.This limits top end power but when ports are not open at TDC you gain bottom end.
The sportwerks and the mach have a design where the transfer ports are open at TDC, the shape of the port also allows unburnt fuel to leave the sleeve and go back to the bottom of the crankcase.This increases higher rpm power because the engine doesnt have to work as hard because there is a place for the unburnt fuel to escape.
The xtm pro has what appears to by a hybrid of the other 2 types.The port closest to the exauhst is larger at the top this allows for more port volume when both ports are open at BDC.
I dodnt claim to be an engine expert so I could be wrong on some things.

[Nitro Quad]

So if I understand you correctly, an engine that has more ports would have a much broader power band than an engine that has fewer ports. Or to put it another way a three port engine would be real torquey but not that fast. While a seven port engine would be real fast with a broad power band, but not much low-end torque.

Sorry, I'm starting to get a real hunger for all this tech stuff. I'm trying to get my hands on that nitro engine book, but Tower is out of stock and I can't find it anywhere else. Thanks for putting up with my endless questions :) .

[thedarkness]

Yes fewer ports equals a more torquey engine, while more ports offers more a powerband suited for rpms.This is a good read too http://www.rcnitro.com/rn/articles/engine_timing.asp

[Nitro Quad]

Thanks Darkness that and some of the other articles should keep me busy for awhile. I do appreciate everybody's help and patients. :)
