Thread started by request, go nuts!

[Joe Brinduse]

I got one and love it . it needs new tires

[fezzy]

Have you guys got any pics or detailed reviews? I have seen very little on what appears to be a promising truggy.

[Imavol]

Just got one this weekend I love it already, agree on the tires they are horrible, put a set of Meat Grinders on it made all the difference in the world. Also put 60k diff fluid in the center looks like it is going to help too. Has anyone tried to mount a wing on theirs yet? It look like it will bolt right up but have not gotten one yet to try.

[Ball Racing]

I put the wing off the buggy on mine.
Had to remove back bumper and put the little buggy skid plate on the back.
Used the buggy wingstay on it too.
I had to cut the body off before the wing for this to mount.

I put 30,000 in my center.
45wt in front shocks, 40 wt in rear.
I put 3,000 in the rear diff, along with the aluminum cases.

I put the jr 650 servo on my steering and the 590 on my throttle

I put the quad brake kit on it.

I put the bigger chassis braces on it.

I put the graphite diff plate, front plate, and servo tray on it.

I put the center cvds on it.

Also I added the threaded shock collars, and rubber boots.

I also put the buggy pro chassis on it, along with the aluminum suspension mounts on it that allow the anti-squat shims in the rear..

I added ball bearings to the steering post.

Thats about all I did to mine so far.

[Imavol]

Which bigger chassis braces did you put? I was looking at mine and thought they looked a little small.

[Ball Racing]

The round rod style.

[Imavol]

Do they mount where the current chassis braces mount or are they mounted on top in additon to the current braces? There is really no explination on Horizions website about them. Thanks

[Ball Racing]

They are a replacement and not a add on..

[Monsterbrad]

post some pics guys

[Imavol]

Don't know how if I email them to you will you post them

[Ball Racing]

Check you steering rack screws for looseness after a few runs.
add a drop of loctite...
add a drop of ca glue to the upper front arms around the hingpin and let it dry.
It will take some of the slop out of them. When dry and you move the suspension it breaks free on the pin , and stays on the arm...

[Imavol]

Thanks for all the great info. I am racing Saturday if the weather will hold off. Cannot wait. Tried your 45wt/40wt shock oil tip out today handled a little better also put a set of Kyosho Blue Springs on the back helped alot too. Chassis Braces, wing mount/wing, Shock Collars are all on order but will not be here by Saturday unfortunatley. Will let you know how I do. Also got a new pair of the Panther Boas mounted up tonight going to try them out this weekend.

[Ball Racing]

Yeah, I had those tires on mine and loved it. I put the blue sport werks spring on the back of mine.

[astainback]

What kind of tires are best for racing with a truggy?? I was just wondering. I have the mayhem buggy, and I have thought about converting it.

[Imavol]

Raced this weekend 1st time out with new truck. Came in 4th not too bad should have done a little better but could not stay off the rails. Nothing to do with the truck though it was the driver. Loved the Panther Boas though. Anybody tried the Proline Crimefighters?

[Ball Racing]

One thing about those tires (panter)
If you can't get glue on the bead area of the boa, your in bad shape :)

[Imavol]

No Doubt.

[Imavol]

Hey Ball, have you tried any other bodies on your truck yet?

[Ball Racing]

Not yet, I would hope a crowd pleser of some kind would fit.
Thats about the only thing I don't like on the truck is the body.

I did lower the mounts as far as I could and cut about a 1/2" of the bottom of the sides, to help with it's bulky look.

[Imavol]

Going to Hobby store this weekend will see if I can fit a CP body to it. Hey have you replaced your stock clutch shoes mine seem to be self destructing.

[NITROSENSE]

Hi all, Are the Chassis the same for all of the sportwerks?

[Ball Racing]

The newest of the chassis have the new extra bolt holes for the extended motor mounts.
Other than that they are the same length and bolt patterns.
Just a alloy grade difference between RTR and PRO

[NITROSENSE]

Ok Thanks :)

[Imavol]

Went to the hobby store and could not find a body that fit really well. Revo/Tmaxx body a little to small, Mgt/Tnx body too big.

[Imavol]

Ball are you and I the only two who have these Trucks? Raced again on Saturday was running in first for the first 6min then had a flame out at pit worked my way back up to 3rd but I should have won. This is a great truck. Did you have to do anything special to put the pro chassis in your truck. I am thinking of getting a starter box and heard it works better with pro chassis.

[Ball Racing]

No, the pro chassis just bolts up.
I still clearanced a little around the flywheel opening for my linking for my box.

You can use a bump box on the standard chassis, but you have to use lowered motor mounts., and cut a little around flywheel opening.

[Satoch]

Any one seen this ext. ST chassis up close: http://cgi.ebay.com/Sportwerks-mayhem-st-1-8-truck-extended-chassis_W0QQitemZ6009083838QQcategoryZ44028QQssPag eNameZWDVWQQrdZ1QQcmdZViewItem or this one: http://files.upl.silentwhisper.net/upload8/fcg_chassis_SWK9126-450.jpg

I'm thinking of just putting a Mayhem together from e-bay parts. A couple of people here in Chicago are running mayhem buggies and one guy the ST. It's a toss up between the ST and the Ofna Jammin CRT.

Hi All... Hang in There, I think You will like the
New Pro Mayhem "ST"RACE TRUGGY CHASSIS We have in development.
It is long and very stable.
This is a example of the style of chassis
I will post new pics Of the "ST" SOON :D

Email me for pre orders..

raceum@earthlink.net

[Imavol]

Good looking chassis, would like to see some pictures mounted up when it is done before I bought one but looks good. How much does it stretch length?

[oswald]

i'm thinking of the new ST sportwerks has released. it comes with spektrum radio for, I think, $550. is that a good deal?

http://www.sportwerksrc.com/Products/Default.aspx?ProdID=SWK1211

[Imavol]

Yes it is.

[1 BADD LOSI]

Just got a ST and I was wondeing what the easiest wing was to mount on it.
Anyone know if the buggy wing will fit it?

[1 BADD LOSI]

Just saw the post by Ball Racing.Was that a direct bolt on?

[Ball Racing]

Yes this truggy uses basically everything the buggy does,
so take off the rear bumper brace, and buy the wing stay and wing for the buggy, and bolt it up.

You will have to cut the body up for this.

[Imavol]

I did not even have to take off the Rear Bumper but did have to cut off the rear of the body.

[Ball Racing]

Right, I just did not want the extra weight of the rear bumper...

[Pat Fierle]

okay, I am sort of considering a new truck and it will definetly be a truggy but was not sure which one. I dont know if i am totaly sold on the Mayhem St but i do like the new radio and the engine is strong from what i hear. So, here is the question, does the Mayhem handle, is it durable, would you recomend it or would you recomend a different truggy. Any help and suggestions are greatly apreciated.

[performula]

How much wider and longer is the ST compared to the Mayhem?

[RVROD]

Hi guys brand new to the forum, just bought an ST about a month ago and gave my stepson my REVO. I absolutely love this truck but can't find much in the way of aftermarket / hop-up parts support for it. Can anybody point me in the right direction.

[performula]

sportwerksrc.com

[RVROD]

sportwerksrc.com
thanks performula, I have gone to their site before but as you can see they don't carry much at all compared to some of the other truggies that have come out after the mayhem st, what gives just does not seem to be much aftermarket support for these

[performula]

Sportwerks has some very good stuff, so I cannot judge by options; however, they have a ton of stuff that is coming up on their site that doesn't have pictures yet. I had the Sportwerks Mayhem RTR - it was blistering fast and gorgeous.

[NITROSENSE]

Hi Mayhem Guys, I have not seen much in racing The ST?
I have parts and a proto Chassis here That I am working on getting
out and start running.
Do You Guys like the idea of running a longer Version with wider arms?
I think This truck has a lot of racing potential.
I love the diffs and beefy parts.

Let me know what you guys think. :)



Bill

[GasGod]

I would def buy a longer chassis.I think that it's probibly the only "shortcomming" on this truck.The buggy is def competitive and the truggy version needs some xtra length on most tracks. JMHO :D

[RVROD]

NITROSENSE
How is the extended wb chassis for the st coming i am very interested in one

[NITROSENSE]

Hi I am just finishing up the Mugen Project .
Here is a pic of that Chassis. The mayhem project will be done after that
I am setting up a shock tower for it also.
I am looking foward to runing it .I like the componets that it comes with. :D

http://i20.photobucket.com/albums/b222/rnucell/msr1x.jpg

[Satoch]

Just traded my spare Revo for a RTR buggy and am converting it to an ST with parts off ebay. I'm keeping the 17mm hexes/8mm axles and running the Ofna CRT wheels w/Boas. I love the .26!!! Great bang for the buck!

I wish someone would make the thicker 5mm shocktowers for the ST. I know Sportwerks is coming out with the extended chassis next year so I'll just use the RTR chassis for this winters indoor season at Leisurehours (where the ST was developed).

I know that Derek Weatherholt and Brian Kadow run this truck but I don't know if they are going to all of the Pro Series races. Some wins at the big races is what's necessary for the attention this truck deserves. The marketing dept. at Horizon has seriously dropped the ball on this truck and that's why no aftermarket companies are making parts. Also why not as many people are running the truck.

Nitrosense, where's the holes on the EXT chassis for the extended motor mounts?

[NITROSENSE]

Hi Satoch
The Chassis still in development, not all of the components
have been set up. The Chassis below is our Pro M Mugen
Truggy replacement . I just put that in so you guys could
see what a finished ver looks like. I am thinking about
some other ideas for the ST , I feel bad about the lack of interest
with it. I speak with a lot of racers, and hobbie shops ,they just
don't get to excited? Also when you look at the new trucks
coming out ,its like everybody wants to jump ship.
anyway tanks for your ideas, I still want to finish up My St project..
I think it will do very well, I will post all of the new pics as soon
as they get done.

[jackace66]

love mine ! 50wt shock oil ft & rear 50k center stock springs blue too stiff w/heavy oil moved stearing servo to throttle and a airtronics 93458 slaps the front wheeles around pretty good tore the bumpers off along w/that ugly body ....literaly ! ugly 1st race with it to much fun to let off the throttle used the buggy body clipped off the nose and used the stock buggy body muonts and also added a wing pro shock towers 23mm pro line hubs hpi dirtbones W/ trinity 3 stage foams cant wait for the weather to break i'm gonna smoke those long truggies on our tight turning track

Hi Mayhem Guys your request have not gone unheard.
Here is a extended balanced racing chassis for your
Sportwerks ST. Some of the features will include
Ofna Tank option (150cc) Billet towers Billet braces,
and a custom 1 piece motor mount.
Pictured is a first run proto. More pics to follow.
Pre order sales will be available soon.

any info raceum@earthlink.net


Thank you Bill

[jackace66]

does any one have any info on set up tips,camber ,caster,shock angles that sort of thing? I cant find anything. thanks

[Ball Racing]

I cut my front arms and moved them ahead one spacer like I did on the buggy.
It all depend on how ,and where you run.
you can use 40wt oil, and run 2 degrees camber, or whatever..
Trial and error........................

[Racerxx]

Finally got try the mayhem out in real race conditions this weekend. To start off it was 54F outside and it was at a major race with about 50 entries in the Truggy class with about 4 mayhems running in. Only running prior I did with this truck was break in. Here are some obvious problems with the Mayhem that all of us were having, or had before and sort of fixed
1. Rear arms are just too weak – Fixed with Alum ones (most opted to go alum all around)
2. Rear shock tower just to flimsy – Fixed with 5mm one front and back
3. Chassis flexes too much – Fixed with custom brace
4. Bumper braces break way too easy – last longer when you boil the bumper + braces
5. Clutch is garbage – went to ofna alum setup
6. Wheel base adjustment spacers kept falling out – fixed by using plastic washers
7. Sloppy suspension - add thin spacers were needed

Comparing the stock Mayhem to Stock Jammins, HB LSP, TT St-1 all under same conditions I would say it is at a serious disadvantage due to having durability issues. The others truggy’s could take bigger hits and keep going than the mayhem in stock form. Handling wise the mayhem with a bit of tuning can keep pace with rest in the infield but high speed sections it gets out of shape. Engine wise I couldn’t be happier, so easy to tune and power that gives some of the more expensive motors a run for their money.

Parts tally for just me was (these all being stock parts) 3 rear arms, 1 Rear shock tower, 1 lower arm, clutch, 1 front bumper and at least 3 of those braces, and lost about 3 wheel base spacers (all in about 30 min of practice running and one qualifier). And a Inner rear suspension mount and 2 hinge pin braces after going alum. Imagine the list if I did not add any hop ups or do any of the fixes to it!

So what’s my opinion on the mayhem St? It is a good rc for some one who wants to mostly bash around with it and maybe do a bit of club level racing. If you go my rout you will end spending more and having a heavy ass truggy that is still at a disadvantage compared to the rest.

Setup
Front - 45w, Stock position, stock spring, 5000 diff, dog bones just below level, -2 camber, 0 degree toe
Center - 7000 diff
Rear - 45w, Outermost upper hole on shock tower and middle on arm, Kyosho blue spring, Inner most lower hole camber link, long wheel base, 2000 diff, dog bones just below level, -2 camber, stock toe in

Pro-line Crime fighters on Rpm stbl maxx “Monster Claws”, Sidewinder 30%, Hitec servo’s

[Ball Racing]

I went up to 30,000 in the center, tires just balloon too much.
I actually cut my rear arms for added wheel base adjustment, and it has been jumped 10 plus feet up, and 30 foot out, and hasn't broke them, even though it came down bad and bent the rear tower.

I put the aluminum suspension mounts on mine.
Alot of the chassis flex is in that factory brace,
I toke the rear bumper off, and bolted on the buggy wing.

I never really broke anything, just upgraded for the sake of doing..
just buy the upgraded round style. I also used teh pro buggy chasssis on mine which is stronger, and milled out.

[jackace66]

this weekend will be the first racing test of mine thanks for all the tips wish me luck

[prc23]

Could you please explain to me how to put bearings in the stearing set up please?

[fsh_62]

Just spent half the day breaking in and tuning my new Mayhem ST. What a beast, I can't even imagine trying to drive the thing with the nine mm carb. insert.

[Philster]

There is a Pro Chassis over at Horizon Hobby from their Sportwerks brand. It looks like it is longer, especially since it is pictured with new dogbones (drive shafts).

Anybody know about this deal? Mayhem Pro FCG Chassis Kit
SWK9126 by SPORTWERKS :confused:

[fsh_62]

I don't know if the chassis is longer, it does look that way but since it's a forward center gravity things are moved, hence the need for different length dog bones.

[Philster]

Right you are.

[NITROSENSE]

Hi All,, Yes the extended ver, will requier longer shafts.

[Philster]

I'm picking up an aftermarket extended chassis (1.5" longer) that comes with thicker shock towers, stronger braces, and a longer rear dogbone for 80 bucks.

LST Crowd Pleazer and Mugen truggy bodies fit it perfectly.

[fsh_62]

That sounds great. Where are you getting it?

[Philster]

Over at RCUniverse market place.

http://www.rcuniverse.com/market/item.cfm?itemId=190171

[fsh_62]

Good Deal, Thanks. I just might have to get one for myself.

I was thinking of getting 1 of these, as it comes with a DX2, but am reconsidering due to this post.....I would hate to buy the truck, and then have to deal with replacing a bunch of parts just to get it to the same level as the others........

Then again, having the "underdog" vehicle can be fun as well....

[Y2KGTP]

Does anyone have close up photos of the body off? I can't seem to find much to look at.....

[rob_s]

Thought I'd bump this since I'm considering an RTR.

[jacquesb]

Hi all, I recently bought a Mayhem ST and would like to now some do and don'ts? You guys have pics of your Mayhems?
