Enough BS about the Traxxas maxx trucks. First off they are not true monster trucks. Watch them race on TNN and when was the last time you saw a truck with 4 wheel independant suspension.

the 1:1 scale trucks use 5 ton military axels and then modify them

I am happy to see that Tamiya has finally built a cantalever truck. I mean the last time I saw leaf springs on a 1:1 scale mosnter truck was back in the early 1990's

I am waiting on a new discount code from Tower to order mine. If I recall they occasionally offer a 10% or 15% off the order codes. Or something like spend $300 and save $25... That is when I will buy my TXT-1

Now is this thing the new mayor of Monster Truck City or what?

You can't touch a Clod or Jugger with cantalever kits for the same price. Yea the swaybars have tie wraps but.....

Have you all seen the video of the TXT-1 jumping a 1:1 Scale Accord? It is on Tamiya Americas web page!

So what puts the "Monster" in Monster Truck anyways? Is it the tires? Is it the axles? Is it the ground clearance? Is it the overall huge size of the vehicle? Or is it all of the above? Does a R/C "Monster" truck have to look like a full size counterpart? Does it have to look like a truck? Can it have a car body or a van body on it? Does it need a body at all? Could it be a bare frame and roll bars like an old style buggy? Why can't a Monster Truck have independent suspension? Maybe, just maybe the what makes a Truck a "Monster Truck" is different for each of us.

Basically I am dumbfounded how anyone can say that the T-Maxx is not a Monster Truck, or how the Monster Pirate is just a buggy with big wheels. Again, it all boils down to a matter of personal opinion.

BTW: A monster truck needs to meet the following for it to be a Monster Truck in my opinion.

Large Diamater tires
High ground clearance
Any body you can fit on it, even a fur covered doggy body. ;)
Good suspension articulation
A gross amount of Horsepower, Full size MTs that is. .15 - .21 for R/C
Any type of drive axle the owner wants or prefers, this is a free country after all. ;)

But this is just what it takes to put the Monster in Monster Truck for me. I don't think there is any "cookie cutter" rules to determine if a truck is a Monster or not.

Just my thoughts,
Jerry

The day I see a 4 wheel independant suspension on a 1:1 scale truck on TNN is the day that I will accept the t/E Maxx and the ofna as true monster trucks. The object of Radio Control models is exactily that a miniature replica of a 1:1 scale car or truck that you drive remotely via radio.

As to the car bodies, van bodies. In the 1:1 scale world both have been done. There was even a "truck" with a hughie helicopter as the body. It was called the Helli-monster.

Jeep,
I think that your TXT-1 is broken or something. It looks like the suspension or chassis is all twisted. :D :p ;)
Thanks for the picks too.

DrDiff,
I agree with you as concerning "competion" 1:1 Monster Trucks. And as far as R/C trucks are concerned I think that there are two classes of these trucks. Scale trucks like the Clod, TXT and Jugg. And then the just pure Monsters like the T/E-Maxxes and Monster Pirate. Which is why I consider the T/E Maxxes "Monster" trucks.

The version of that quote that I usually use is "Opinions are like arm pits, everyone has them and they all stink". That is actually the clean version. :D

11-23-2001, 11:23 AM

I have been seriously thinking about getting one too, but its very hard to justify the cost of one of these toys.

TXT-1 - ~$360 (WITHOUT Bearings)
High Torque Servo - $50 - $100
New Motors - $100

Ok, thats $500 WITHOUT any radio gear, batterys, or a charger.

I've already got my radio gear, so its not an issue, but how many people are going to go out and spend most likely around $800 to start out from scratch with one of these?

I know I wouldn't. Not when you can get a RTR EMaxx for ~$400.

Hmmm.... I think Tamiya needs to re-think the pricing of this baby.

Well, the wife finally OK'd the purchase of a TXT-1 next week. *SWEET*

Now I've got a few questions for you all. (Mainly Jeep, but anyone can contribute)

What servo should I use? I know I need a High Torque one, but there are so many out there, and so many different price ranges. I use Ko Propo radio gear (EX1 Mars), and I'd love to get a Ko Servo, but if you've ever seen the prices of there high torque servos, well, you'd understand. :)

And how about any other MUST HAVE upgrades that I'm going to need from the get-go. Thinking about the Traxxas (Novak) EVX Speedo, but the Super Roster also looks good. Any thoughts?

Maybe some motor heat sinks? I'm going to use the <slow> stock motors for a little while, because I'm building this thing on a somewhat limited budget. :( But at least I get to buy the truck.

All I know is that I had a Clod Buster years ago, loved it to death, almost cried when it disapeared (I'm not kidding, *POOF* gone with the wind) over the years, and now I can hardly wait to get another monster.

Any other recommendations would be greatly apprecaited!

I don't have a TXT-1, so I can't help on all the points, but I do have an E-Maxx, which is similar in weight and also uses either of the two ESC's you mentioned, depending on what motors you use.

First off; servos. If you want some inexpensive, high torque servos, I would highly suggest looking at the Hitec 645MG, 925MG, or 945MG. The 645 is ~$50 and the other two are ~$90. The 645 and 925 have ~120-130 oz/inch of torque(at 6 volts, i think), and the 945 has ~150 oz/ich of torque(again, at 6 volts, but I'm not too sure on that, however the only other way would be 4.8 volts, which makes it even better:))

Second:ESC's. Either of the ESC's you mentioned will work, but there are some significant differences between the two you should consider(other than price). First, the EVX is designed to be run with 12 cells, and delivers 14.4 volts to EACH motor. The EVX is also designed to be run with the 550 type motors, not 540's, though it should work with the 540's(but I'm not guaranteeing anything with your motors...hehe ;) ). The SR is also a great ESC, though I don't have any hands on experiance witht he SR, I know people with it, and love it. The SR is designed to be run with the 540 motors, but it can be used with 550's(I'm not sure on performance with the SR and 550's). Also, the SR cannot use as many cells as the EVX(it has a 10 cell limit...if someone owns an SR or knows otherwise, feel free to correct me). So, in short, if you are going to use the stock motors I would suggest getting the SR, but if you want to try out 550's, go for the EVX. They are both great ESC's.:) Hope that helps, lol.:D

Thanks for the reply Jeep. No worries about being a little late to reply. :)

I just got my TXT-1 yesterday. I was crusin a somewhat local hobby shop, and they had one that was already put together and mever used. Seems the guy didn't realize what he was buying. It was a price I coulnd't refuse. hehe

One thing I noticed though, with the body off, the front end sits a little higher than the rear. Is this normal? Or was my truck built by a guy who didn't know what he was doing?

TXT-1
No bearings
Slow (but this is really cool for the climbing torque and realism)
Shocks are weak
No foam in the tires
Expensive
Skid plates that the steering servo mounts too are plastic and weak
The rails that the skid plate connects to is plastic and flex when you steer
Cheap cheesy motors
No ESC included
No radio included
Very poor customer service (no 1-800 number and if you contact Tamiya by e-mail they tell you sorry about your luck we already got our money)

The TXT is one awesome truck after you spend the extra money on bug fixes and modifications. I love mine but my wallet doesn't.

Hairball

11-25-2001, 08:49 PM

Wow, thanks for the offer Jeep! (about the spare parts that is)

Mine still has the plastic shocks, and I have the C-Clip thingys, but there are none on it right now, and it still sits higher in the front (about 1/4" I think).

I was looking at the instructions (a little confusing IMO) and it looks like one set of push-rods for the cataliver setup is longer than the other? Am I reading that right?

I didn't get the extra clear body with it (seems the original body basically ruined it with automotive paint). But everything else seems to be in good working order.

A few more days, and its off to the hobby shop to finish this truck! (Or at least get it running that is)

So mine is set up backwards then? Neat, now I've got a reason to tear it apart! :) Woohoo!

What kind of run time did you get with an eight cell pack Jeep?

I'm lost on wether to get a Traxxas / Novak EVX and run E-Maxx motors, or get a Novak Super Roster and run Speed Gems (like 18T or something).

thanks in advance

11-27-2001, 01:20 AM

Well, after tearing my truck apart and comparing the front and rear rods, one set is WAY smaller than the other.

I'm starting to think the guy who built my truck was a moron. :(

Gives me somthing to do though!

I went out and bought a Traxxas/Novak EVX and a Hitec HS-5925MG Servo tonight. They didn't have the 945 in stock, and I refused to wait till next week. I guess 102 oz of torque is just going to have to do. :)

Hairball

11-27-2001, 08:29 AM

Thanks Jeep. That one looks just like the one I have right now, except mines white. I'm not sure if its the kit's original or not. The more I get into this truck, the more "mickey-mouse" stuff I'm finding. Nothing major, just little things.

I'm thinking about replacing the catilever pushrods with a set from lunsford, so they all match.

Hairball

11-27-2001, 11:43 PM

Had my first run today! Just ran it around the house a little, trying to get it to run correctly.

First of all, is the servo supposed to make a high pitched sound when its *idle*? This is my first digital servo, so I'm not sure what to expect.

Next, I'm running two 2000 packs, the EVX Speedo, and the stock motors (didn't have the cash for mod motors. *soon*). The EVX was starting to get really warm, and the motors were just plain HOT. I'm not going to run this setup again. Don't want to burn anything up.

The steering wasnt what I had hoped for. It seemed to turn a little slow, and the wheels didn't seem to "move" as far as I thought they should. Probably why most monster trucks have four wheel steering.

Jeep - When you hit the gas with your truck, does the whole chassis seem to lean to one side while your driving around? Could just be a bad case of torque-steering, but it doesnt feel right.

What weight shock oil are you running? I've thinking thicker is better. The stock weight feels weak. Maybe some stiffer springs too.

I think I need to re-mount the servo too, and get a better servo saver like you mentioned before.

Rats.... after a bunch of pleading and begging I finally had my wife convinced that I REALLY needed a TXT for Christmas. Then I went to my LHS to check it out. That thing looks awesome but they (the LHS) can keep it..... They had it priced at $699.99CDN. Even with the exchange rate it is still about $125 over priced. I tried to talk a deal with the manager but to no avail. He said that if I wanted the only one in town I had to pay the premium price for the "honour"...... pffffft to him. :p :p :rolleyes: :(

I don't understand how a monster truck that does 5 m.p.h, comes with a MSC, has nothing special motors, has no radio (cost care less about this feature), but cost $500!!! Gimme a break.
My other opinion is that tamiya isn't a very good R/C company. I mean just look at their stuff. What do they have that is cool?

Hairball

11-28-2001, 10:43 PM

RC - You obviously don't own a TXT-1. If you did, you'd understand what Jeep is talking about. I just got mine running LAST NIGHT, and IT ROCKS!

Its like, the coolest thing since sliced bread or somthing. :cool:

It is a little pricey, but life is short, and remember, you can't take your money with you when you go, so spend it while you can! hehe

Jeep - Fixed that little HOT ESC problem I was having. Installed a 1 1/2" 12vdc ball bearing fan right on top of the esc. It keeps the heat sinks nice and cool. :) No more worries about overheating this EVX!

Now I just need some motors. E-Maxx motors, or standard 540 size mod motors.... geesz, life is so complicated some times. ;)

Hairball

11-28-2001, 11:35 PM

My biggest question is, weren't these motors designed to work on 7.2v? Is 14.4v going to hurt them / rapidly shorten there life span?

And how about the TXT-1 drivetrane? Is it going to hold up to the abuse of TWO mod motors? I know its going to be balistically fast, buts that only fun if you don't ruin the truck in the process.

*Update*

Well, after many hours, my Txt-1 now has full ball bearings, and is running two Trinity Speed Gems 2 19T Doubles, and I installed Ofna Monster Pirate foams in the tires.

HOLY CR*P is this thing fast! Run time has been cut down a little, I'll try and time it later.

But a word of advice. SLOW DOWN before even atemping to turn. Hehehe. Its a bit top heavy, and likes to roll over when turning at high speeds. Guess I'm just too used to driving a buggy. :)

I bet you can pull wheelies at will, even after moving pretty good.

Be sure to order a few sets of those Peak brushes I mentioned (pek2151). The factory brushes in those speed gems motors are HEINOUS.

Hey Jeep-

2 Packs, EVX, yes. :) Wheelies like its going out of style. :cool: Actually, if you hit full throtle from a stand still, it'll do a back flip on you. hehe

For my first run, I just used the stock brushes, my LHS didn't have any Peak 2151 brushes in stock. :( They recommended Trinity 4380 (Serrated Hard Brush, Hard Copper Compound). What do you think about this?

The motors were getting a bit warm, almost hot. I'm using 18 tooth pinions right now. I want to try some 19 tooth ones.

I think I need to get some heat sinks on them to be honest. A cool motor is a happy motor. I'm running a 1 1/2" fan on the EVX, so I don't have to worry about it overheating any time soon.

Oh, I also adjusted the timing on the Speed Gems to zero degrees. I did this because the truck run in both forward and reverse, and the manual recommended doing so to prevent ESC damage.

Speedie105-
I put my packs in vertically side by side. I'll try and post a pic of it later tonight (that is, if my digital camera will behave). I use Trinity power pole connectors and this was the only way to get them in.

Bluesy-
Congrats! Its good to see the TXT-1 getting some more support! Just be warned, this truck is VERY addicting, and be ready to drop some serious cash on it in the future. hehe I think I've got around $650 - $700 in mine so far.

Bluesy - One quick suggestion. Before you start building this bad boy, if you can afford to, buy the rest of the bearings to complete the truck. Its so much easier to put the bearings in from the get go, instead of building it with bushings, then tearing it apart later to install bearings (like I did).

You'll need -

16 - 6x12 bearings for the axles (8 each)

8 - 5x11 bearings for the axles and tranny.

11 - 5x8 bearings to finish up the axles, tranny and cantilever system.

I can't wait for christmas to get here. I asked for hopup parts but do not know exactly what I going to receive. Hopefully an EVX. It sounds from you guys it is the way to go. Did anyone get a set of the Trinity 550 motors to use in the TXT?

Hairball

12-03-2001, 10:08 PM

I read somewhere that due to the cost of Trinity 550 motors, and there realativily short life span, that they were not worth the money.

And the fact that most lathes won't cut 550 armatures (I know mine won't).

When you choose a set of motors, think about how much its going to cost you in the long run, not how much the cost up front.

speedie105

12-04-2001, 09:06 PM

Hairball:
How about the EVX with Trinity Speed Gem 16 triple? Or a pair of Novak rooster esc with the Trinity Speed Gem 16 triple?

I took out the stock motors and put on 2 Chameleon motors. It ran for about a minute and overheated the stock speed control. Can't wait to get the evx.

Hairball

12-04-2001, 09:36 PM

The EVX says it has a motor limit of a MAXIMUM of 19 turns. I know that the Trinity Monster Maxx Pro motors are 17 turns, so I'm guess any 17 turn motor would be ok.

But to be honest, I wouldn't go lower than 18 or 19 turn myself.

Trust me, mine with two 19T Doubles pushing it it INSANELY fast, almost to fast.

I'd try that first, and if you want more, go from there. Also remeber that the lower the motor turn, the faster your packs are going to run out.

I'm thinking I get about 10 minutes of run time right now with TWO 2000s.

Think about charging time too. I'm lucky enough to have two Millinnium Pros to charge my packs, so I can charge two in about 35 - 40 minutes. With one charger, you're looking at about an hour and a half of charging time for 10 - 15 minutes of play time.

Hairball

12-04-2001, 10:56 PM

Jeep -

It says

"Motor Limit..........19 turns minimum (550 size)"

Now that I'm looking at it again, I'm not sure I understand it. hehe

If its saying that 19T is the lowest you can go, why does Trinity sell 17T motors to work specifically WITH the EVX? I'm lost.

Another question Jeep, about those PEK2151 brushes. My LHS didn't have any in stock, but they told me Trinity Hard Copper Brushes would work the same way. What do you think?

Mods????? Thanks, my wife was reading your post and said mods ====$$$$$. LOLOLOL. Not sure about mods. I kinda like long run time and I'm okay with the performance for now.

I'm gonna get rid of those mickey mouse sway bar tie downs. I found some tiny hose clamps at an auto supply store. NOt quite as sophisticated as mini gear clamps but I think they will be just as effective. Pix later this evening.

Bad news guys. Today I blew out one of my tranny gears. The Top-most gear (not the spur, the one that spur messes with) pretty much destroyed itself.

Maybe 19T motors wasn't such a good idea after all. Hehe

Whats even worse is that I'm 600 miles from home right now, and my spare set of gears is there. :( So i've got one dead truck right now.

Has anyone considered getting a set of METAL gears made for the tranny? I'm thinking this would be the way to go, could be expensive though. But then again, one set, and you'd never need another. :)

I'f I get my FTP site to work, I'll get some pics of the blown gear up soon. its missing like 8 teeth. :eek:

Hairball

12-09-2001, 12:04 AM

I'd bet money on the fact that they broke due to weak gears / too much torque. Probably the reason Tamiya included 540 stock motors, nothing fancy.

The teeth broke off right an the base (hard to explain). And there was very little left of the peices that broke off. Wierd. My tranny seemed to be well lubed, and it wasnt heating up at all, plus I install full ball bearings in the tranny just last week. Ugh.

I'll post some pictures when I get back home tomorrow and tear the tranny apart again. I bought a worthy digital camera today, so the pics will be very good. (Nikon Coolpix 995, hehe)

I'm planning on getting a set of metal gears made for this truck if it doesn't cost too much. If the cost is insane, I'll probably be installing an E-maxx tranny pretty soon. :rolleyes:

Sorry to hear about your gear troubles Hairball. I have been running Trinity 17-turn motors with 14 degrees of advanced timing, an LRP F1 Pro Reverse ESC and the stock pinions for about 2 months now in my TXT; to date, I have had zero gear problems and have broken nothing on the truck. I don't baby my truck either - I trash my truck hard and take wild jumps.

Here are a few photos of my truck with an E-Maxx body and New Era Center Skid Plate:

By the way, I put up a TXT FAQ page a few months ago. Some of you might find it of use :D

Dr. Doug's TXT-1 FAQ ... (http://home.att.net/~dgelowitz/txt_faq)

12-10-2001, 01:18 PM

Dr.Doug.... Thank you for the time and effort you put in making your TXT-1 FAQ page. I just finished reading it and found a bunch of useful stuff there. Thanks again. Please check out an earlier post for pix of my humble solution to the cheesy anti sway bar tiewraps that Tamiya shipped with the kit.

BTW... I love this beast... I have been rock climbing it quite a bit. I don't get it as dirty as Jeepinator gets his. (Guess I am a wuss).

Thanks again..... bluesy aka Doug:cool: :cool:

Doctor Doug

Thanks, bluesy! I really like the TXT too, but it definately needs faster motors and an ESC to be really fun :D

Oh, and your sway bar fix is cool too.

I just ordered my TXT.I am going to be runing Monster Maxx mild motors in it.What would be the pinion pitch to run with these motors.T.I.A. P.S. all you guys trucks look great.

Doctor Doug

12-10-2001, 10:59 PM

The TXT-1 comes with 15-tooth, 32-pitch pinions. I suggest 18 to 20 -tooth, 32-pitch pinions for 550-size, 14.4 volt motors. The larger pinions improve the top speed, plus you'll still have more torque than you'll ever need :D

Hairball

12-10-2001, 11:19 PM

Hey Jeep, I thought I put 18s on it, and you were the one sticking with the stock pinions. :confused:

Hairball

12-11-2001, 12:49 AM

STILL WAITING!?!?!?!?! Are you kidding me?

Your EVX was DOA, and Traxxas then made you send it to them for repair, and now you've waited like 3 weeks, with still nothing.

Novak would have had it back to you within the week.

Anyway.

My motors do get a bit warm during operation, maybe I should gear it down a bit, go back to the standard pinions and give it a try or something. But then again, I JUST (like 2 mins ago) got done putting the truck back together after replacing the blown gears. I don't think I'm ready to tear it apart again just yet. Need to get a few runs on it first. :)

Oh, and check out my new Ballistic Stupidity skidplate. :cool:

Thanks for the clarification Jeep.

I bought the BS Skidplate because it bolts onto the frame of the TXT-1, instead of bolting onto the tranny case like the New Era Models does. It was cheaper too. :)

Jeep is correct about the New Era Center Skid. I have this skid installed on my TXT. The U-shaped brackets bolt to the metal frame, not to the plastic center gearbox. The skid is well made, it looks great and New Era shipped it to me in record time :D

Hey guys.......... I'm using a Hitec HS-645MG servo for my steering. The specs on the box list it as having 133.31 oz-in of torque. I haven't been able to try it outdoors for the last few days.... tons of rain here.... but when I try to run it on the carpet in my living room the servo doesn't seem up to the task of turning the beast. As well, the servo-saver??? fell apart tonight. What's going on with the steering on my beast. Is the traction on the carpet just too much for the servo and should I just be running it outside???

BTW Jeep..... check out the connectors.........

Here (http://www.projecttwin.com/txt.htm) is a bit of info and a few pics of my TXT-1 with E tranny and dual battery set-up. There's also a list and pics of a few changes I made to the truck.

I'm using 1500 packs with a Tempest ESC. I made a lexan tray (plate) to mount the batteries and radio gear. Before I made the plate, I ran 2 stick packs in the stock battery tray, just flip them on their side and zip-tie or velcro them down. Tamiya even molded slots into the tray for you to do this. :D

There are more threads on the TXT in the monster trucks forum....

I have been reading this thread for a couple of weeks now trying to make a decision on what MT to purchase. I already own a T3 and my RC geeking buddy owns a E-MAXX. It seems that every time we run our cars he is making a trip to the LHS to replace broken parts after our run. At first I couldn't figure out why anyone would run one of these beasts until about the 32nd time he ran over my T3 laughing out loud:mad: I decided it was time for a change. However I do love my T3 and dont like the thought of going to the LHS after every run. So to make a long story short how does the TXT hold up compaired to the E-maxx.

mustardplug

12-15-2001, 04:11 PM

I spend 99% of my driving time with my friend and we have a blast. I just want something diffrent but functional equal but not the same ya know? everyone knows that in real world applications solid axle suspension smokes independent suspension.

bluesy

12-15-2001, 04:22 PM

I just got back from my favourite "rock garden". This place has grass all around with many rocks sticking out. Some of these rocks are 5 to 6 feet high with all kinds of cool contours. The TXT performed as billed. A true super star. The only thing that stopped this beast was when the incline was too steep at the beginning. Once it got onto a rock (no matter how steep) it would go wherever I wanted it to go. I had my E-Maxx along at the same time (for its first run after some aftermarket stuff). This is an entirely different truck. Very quick on the level to lumpy stuff and a blast in dirt or sand. Climbing.... let's just say the TXT could have pulled the E-maxx up the rocks faster that it did by itself. I have a feeling the suspension is set up way too soft. I glued the tires on the TXT and WOWW... it will wheelie on command and with no tire slip it just keeps on climbing.

BTW... jeep... the servo does just fine in all outdoor conditions, I guess we were right about the carpet indooors being to traction(y). I now have Dean's plugs on all my batteries and ESC's. I hard wired the motors on the E-maxx today. This is sure a way to a neat wiring job.

Hairball

12-15-2001, 08:47 PM

As far as hanging with an E-Maxx as far as speed and stability, good luck. I've got two 19T Doubles in mine, it it flies, no doubt about it, but try turning at full speed, and your going to have one very upside-down truck. :D

I was thinking about playing with the suspension, and maybe lowering the TXT via the cantalever pushrods (installing shorter ones), that would give it a lower CG, and help it corner better.

You could also install a E-Maxx tranny like some others have done, that would give you some nice advantages. But that would also get away from the original purpose of this truck.

And when you go with bigger motors like I have done (and Jeep, and Clayton, and a few others), make sure you install FULL ball bearings in the beast, to cut down on wear and heat build up. And to be on the safe side, I COVERED (and I mean I used a ton by this stuff) the gears in the tranny with Pennzoil Synthetic White Marine Grease. You can buy small (well, sort of) tubes of it at Walmart pretty cheap.

This grease will last a LONG time, and hold up to just about anything you throw at it. I'm sure some of you are going to say this is overkill, but once you blow a set of tranny gears like I did, you'll start to think twice about it. :) Heres a picture of the stuff I used...

12-16-2001, 11:27 AM

Anyone of you had a problem with binding in the diffs? Both of mine seem to be very smooth for half a round of the tires and then get real tight for the rest of the round. This is only when turning one wheel while holding the other so I believe it's in the bevel gear assembly in step 10 because if I turn both wheels loose and turn the input to the diff by hand both wheels turn very freely. I have full bearings installed and plenty of the supplied grease. This seems to be with both diffs. Thanks for any help.

I picked up a new servo saver at the lhs yesterday. It has a logo that is a diamond with KP inside. The hobby guy said it was Kimbrough. I haven't had chance to run it outside but I gave it the carpet test and I got full steering movement. Thanks for the tip Jeep.

It's good to see the thread back on topic were it belongs. Thanks to Clayton and Jeep.

Clayton.... I notice that your location line is Richmond, BC... mine is Victoria. Maybe we could hook up when I hit the mainland???

StevePond

12-16-2001, 12:03 PM

The servo savers I've used for trucks (T-Maxx mostly) are those from the Serpent 1/8 on-road cars. The have very strong springs, which makes for precise steering movement, but you need to be running a sptrong servo.

bluesy

12-16-2001, 12:22 PM

SteveP... I'm using a HitecHS-645MG listed as 133.3 oz-in of torque @ 6vdc. I've been told this is powerful enough for most MT applications. The Tamiya servo-saver was easily over powered by the servo and the traction generated by the huge tires on my living room carpet. Outdoors it worked until I got into a rock climbing bind..... .. just when you DON'T want it to "save the servo".

Thats exactly what I was thinking. But I'm a total perfectionist, so I'd end up buying all four, and I'm not sure that I want to dumb another $100 into my TXT-1 right now. hehe

(give me a few days to convince myself its worth it, then I'll do it)

But for the rear, I'm really looking for something more like this -

Its more than just appearance. Its functionality too. The Clod (and all versions / mods of it) still have the motors on the axles, not very realistic. The TXT-1 uses a gearbox, and drive lines to transfer the power to the axles. Its beefy too. Uses metal gears in the axles so you know they'll hold up.

It guess it all comes down to how much you love you monster truck though.

And saying the you already have a Clodzilla IV, not a cheap toy by any means, sounds like your already pretty commited to the hobby, so the price of getting into a TXT-1 won't be a big shock to the system. :D

Why is it that there are no f'ing hobby shops that carry replacement parts for the TXT-1? Even Tower doesnt have anything.

I mean, ask for a E/T Maxx part, and they'll sell you 100 of each, but TXT-1, you get a response like, "I've never heard of that before"

I've already had to order a few parts from Tamiya directly, and they don't even have them!!!!!!! *** is going on here? Someone's ***** needs to get kicked for this, I just wish I knew who.

I was going to post this before and forgot to before I went biking...
The gears from what I understand arent actually cast..

Same problem applies though..

They take a chunk of some sort of alloy mixture and compress it into a mould forcing it into the shape of a gear, I looked into this last year for the Bruiser, the gears were cheap, the form was thousands of dollars..

I cant remember what is it called.. it does the same thing though, imperfect gears..

Jeep, we agree... we should leave it one though, one small step at a time..LOL!!!

As for the link braces, they retail about $10.00 a set of 4..

Ok, nobody laugh. :rolleyes:

I started looking at my broken truck, and came up with this -

http://pweb.jps.net/~hairball/fix.jpg

Its Ghetto, but it works, and it'll work until my new parts come in. I turned the broken mount upside down, and super glued it back together. The broken part is now on top of the axle, so it won't be stressed by the suspension so much.

I basically copied Jeeps idea, but used what I had on hand to complete it. Clear plastic lexan and all.

But, and my last run, I'm getting a clicking noise when I hit the gas. It could be a driveline slipping, or a gear going out again.
I'm just praying its not another gear. :confused:

I'm going to tear it down later, I'll let you guys know what I find.

Clayton

The truck will click sometimes, however, check the allen screws holding the drive shafts together, one may have come loose.

My truck clicks up to a certain speed then stops clicking..

Hairball

12-16-2001, 08:56 PM

I have a Dremel. hehe

The tie rods are slightly different lengths. And you can laugh all you want. It works for now. I spent about 10 minutes throwing it together, so not a lot of planning and thought went into it. I didn't want to spend any cash either, and the nearest hobby shop is 45 mins away, so I didn't want to drive.

This was a, "how fast can I fix my truck" project. hehe

Ya know, now that I look at that pic a little closer, I wonder If I have the hubs mixed up? Maybe thats why the rods are so jacked up.

And the clicking noise is the loudest when I hit the gas from a stand still. It sounds like a snap almost. Oh well, somthing else to fix. :)

Oh, and spare parts? What are those? You mean the parts you order from Tamiya when the originals break right? hehe

No, I didn't get much of anything with my truck, and what I did get was screwed up to begin with. My TXT-1 has been more of a rebuild project than anything else. :)

Hairball

12-16-2001, 10:13 PM

You've got a garage right? I HIGHLY suggest getting an end mill. Or even a "Smithy" (Mill lathe combo machine). Its a bit of an investment, but wouldn't having your own mill / lathe combo just rule? You wouldn't believe the stuff you can do with those two peices of equipment.

Check out www.smithy.com and look under metal working. But be careful, you might end up adding it to your christmas wish-list. hehe

I'm lucky enough to have both (in Sacramento, but hey, there still mine) and I've used them for countless projects. Before I joined the Corps, I was really big into firearms, so I got the equipment, and basically turned into a gunsmith. :) Thats what I originally enlisted for (armorer) but the USMC thought I'd make a better Motor Transport Mechanic. Funny how these things work out.

Heck, if you really want to go nuts, pick up a MIG welder (got one of those too) and just think of the R/C stuff you could build. hehe

If you don't want to go totally nutso, you can get a good sturdy drill press, and then bolt an X-Y vise onto it, and but some end mill bits, that would make your graphite cutting projects a lot easier. I've used this type of setup a number of times. Works great for cutting soft materials, but anything harder than aluminum, and you'll need a real mill.

When I get my New Era parts in, I'm going to have my guy at work copy one set of them, but cut up to work like your setup. I'll try and get a set made for you as well Jeep (since I stole the idea from you in the first place). They may not be CNC perfect, but they'll be 10x stonger than the plastic you've got on there now.

Be sure to dust of metal particles before rebuilding ;)
I had some of that in there.

To make building faster (get to the rocks/dirt faster), build up the axles with half the screws tightened down. you don't have to install them all. Then chuck up the input shaft on the axle to a drill and give it a go. Your gears will be "run in", you won't have to tear your whole axle apart, and you won't have to rip the entire truck apart. You'll just have to do it the first time.

Well, more bad news from Hairball.

Blew ANOTHER tranny gear tonight. This time instead of tearing teeth off, I SPLIT one of the other gears, and in the process messed up the gear at the very bottom of the tranny.

AND I broke one of the front support braces the same way I broke the rear one a few days ago. (No pics tonight, too tired to get the camera out).

This is really starting to bother me. I'm just about ready to give the TXT-1 the WUSS truck of the year award. I don't think I've had a day yet without breaking something.

My plan now is to install an E-Maxx tranny (don't hear about guys running them blowing tranny gears).

So, now to install my THIRD set of gears (I replace all four when one goes) in the truck, and start building a E-Maxx tranny on the side.

I wonder if Tamiya is listening?

Yes, but I'm heard of people bolting in 12T Doubles and not having problems. Why are these 19T motors KILLING my gearbox? -sigh-

I havn't cut my comms yet, but I do take a good look at them every time I tear the truck apart (which is about every third run), and they seem to be wearing nicely. I'll try and get the motivation tonight to break out the lathe and cut them, so I can give you a report on it.

I would say that I've got around 10 - 12 runs on the motors now since I installed them along with the EVX.

Jeep. I'm sorry to hear about your problems with Traxxas. I've never liked Traxxas myself, and I only bought the EVX because its a "one-of-a-kind" item. I'm jus hopeing mine doesnt blow anytime soon.

Oh, I'm still running the 18 tooth pinions. I was thinking that is I increased the size by a few teeth (like 20 - 21) I would cut down stress on the gearbox. Any thoughts?

Well, the motors get hot as it is, so I'm not really worried about it. Going to put some heat sinks on them soon anyway.

And.... I got my New Era Lower Supports today. All I can say is *SWEET*. They fit perfectly, are really beefy, so if I break these, I've got problems, and just look damn cool. I love aluminum. :) They seem to weigh only a hair more than the stock plastic ones too.

I can honestly feel that this should have come with the truck in the first place. Plastic should NOT have been used.

On another note, is anyone out there running TWO Novak Super Rosters in a TXT-1? I'm wondering is this setup would better than an EVX because of the over voltage problems with running an EVX with 540 mod motors. Maybe I should run some E-Maxx Stock motors? Any thoughts?

I'm going to start building an E-Maxx tranny on the side, so when I complete it, I'll be installing it in my TXT-1. Maybe it will be worth it, maybe it won't. Only one way to find out right? :D

Hairball, the Super Rooster can handle two motors out of the box. This is the ESC I have on my Clod running to two 17T singles in series. In series there's still no motor limit while in parallel (positive lead goes to both motor's positive leads and negative leads go to both motor's negative leads) you shouldn't go less than 15 turns. Make sure the motors are the same!

Are your batteries wired in series or parallel? Parallel gives the ESC 7.2V but twice the capacity of a single stick pack while series gives the ESC twice the voltage with the same capacity of a single stick pack. A standard stick pack has six 1.2V batteries wired in series giving 7.2V (6X1.2=7.2).

As for your geartrain problems, since you didn't build the truck, is it possible that the guy who built it put something in wrong in the axles or the tranny?

I didn't build is out of the box, but I've built, and rebuilt the truck about 5 or 6 time now, so I'm sure everything is right. :)

I'm running a Traxxas / Novak EVX which supplies 14.4 volts to each motor. I'm running two Trinity Speed Gems 19T doubles. At 14.4 volts each, these motors put out a TON of power. Way more power than the TXT-1 gearbox was designed to handle. The EVX uses two six cell packs in series.

I was thinking about TWO Novak Super Rosters for two reasons.

1) Having a dedicated ESC for each motor. That would give each motor the 7.2 volts it was designed to handle.

2) Still being able to run two battery packs, so that the truck would get better run times. Having two motors suck on a single pack is just no good.

I have two other options that include keeping the EVX speed control installed.

A) Have a skilled machinist make me a set of steel gears for my TXT-1. Then I could pretty much put any motors I like in the TXT-1, because I know the gears will hold up. I have a friend looking into doing this for my right now, but becuase the project is very complicated and would take many hours to complete, it looks like he's not going to be able to complete the project for me. :(

And if you've ever delt with a commercial machine shop, you know that most don't have the time for something like this, and if they have the time, they want something like $50 - $150 AN HOUR for a project like this. That would leave me with a beautiful set of precision gears for my TXT-1 that set me back anywhere from $300 - $700 (Please correct me if I'm wrong on the prices). I can afford this, but it would be absolutely insane for me to pay that kind of money for something like this.

B) Spend somewhere around $100 and install an E-Maxx tranny in my TXT-1. This makes more sense because the E-Maxx was designed to run on motors running at 14.4 volts so it has a MUCH stronger drivetrane than the TXT-1. And it would also give my a 2 speed tranny. Very cool.

Any others ideas / thoughts? What would you guys do?

And a questions for you E-Maxx owners out there. Can the 2 speed be shifted on the fly? Like while your driving it? Or do you have to come to a complete stop, and then shift it?

PCC

12-21-2001, 04:25 PM

Hairball, are you sure the EVX puts out 14.4VDC to the motors? If so then the batteries are wired, internally, in series. To test this connect one battery pack to the EVX and see if you can turn it on. If so then they are wired in parallel. If not then series. Parallel gives 7.2VDC to the motors.

As for running two Super Roosters, I wouldn't. It's designed to handle one or two motors so you won't do any damage to it and, because ESC's have some voltage losses, you will have a slightly longer run time running one ESC.

As for wiring two stickpacks to the ESC, if you wire the batteries in parallel (positive to positive, negative to negative) you will get twice the run time compared to a single stickpack. This opens up the option to run a single battery for those times you want to just do a quick blast. Wiring it in series will give too much voltage to the Super Rooster and possibly damage it. You need to run both sticks when wired in series because the second stick completes the circuit, unless you put in a jumper.

Well, I went out and bought an E-Maxx tranny tonight. Just got through building it too.

All I can say is Tamiya could learn A LOT from Traxxas. This thing is BUFF. BUFF with a capital "B" even. AND IT HAS A SLIPPER CLUTCH!! WOOHOO!!!

I'm going to install it this weekend, after I have time to build the mounts on my mill.

I have one question though. The shifter shaft comes with a rubber seal, which leaves my to ask why? I mean, the shaft fits very nicely into the tranny housing, so I don't think it needs a seal. Then it hit me. Is this tranny filled with fluid? Can anyone shed some light on this? I put a light coat of grease on all the gears, but I'm still feeling weird about it. HELP!

I'll try and get some pictures up this weekend after I get the thing installed. And I'll post a full review of my findings while running the E-Maxx tranny. :D

Hmm, Maxx speed control, Maxx Tranny, what am I going to steal from the E-Maxx next? ;)

ProjectTwin

12-22-2001, 06:21 AM

Sounds good Hairball!

Next thing to steal from the E....driveshafts! (and Titans, of course)

The rubber seal is there to help prevent dirt/sand/whatever from being on the shaft and working it's way into the tranny.

When you put that E tranny in...make sure the pinions face the front of the truck...I goofed and made that mistake, the whole time thinking my radio was reversed on throttle channel...:rolleyes:

Get pics man!

12-22-2001, 07:19 AM

Whats wrong with the stock TXT-1 driveshafts? All I have to do is shorten them a little right?

And I've going to stick with the Speed Gem 19T Doubles I'm running for now. I have great faith in the Maxx tranny, so I don't forsee any problems with it.

Now all I need is a 3ch reciever and a place to mount the servo. :)

Hairball

12-22-2001, 09:13 PM

What kind of battery are you running? E-Maxx motors were designed to run on 14.4 volts. A super roster only puts out 7.2 volts, so you are under powering then, and that could cause them to be slow.

ProjectTwin

12-22-2001, 09:19 PM

Hairball,

I was just trying to guess what the next Maxx part you use would be. The Maxx slider conversion is pretty popular with the Tamiya MTers, due to the yokes fitting the 5mm shafts and being simple to install. It' also easier (and cheaper) to pick up a bag of Traxxas slider shafts than to buy new Tamiya shafts.

About the E tranny being strong...They'e been handling dual Modeltech brushless for quite a while now. I'm about to stick one in my Jugg on the stock Juggy tranny until I find another E tranny.

Dunaway18,

How many cells are you running through the 'Rooster? The Trinity motors you are using are designed to work at a higher voltage, 14.4 volts. Your motors probably aren't getting enough voltage.

I'm gearing down a bit...
http://www.projecttwin.com/images/txt/gearingdown.jpg

Going to 10 tooth pinions (pictured on left) with 72 tooth spur.

The 540 shafts are a bit short (but they will fit Titans great), and these aren't even pinions, they're part of some gearset for a Korean made R/C. I drilled them out, tapped them, and stuck a grub screw on. I might try them tomorrow, but I still need to make a new top plate.

Hey ProjectTwin, whats up with you only running half of the slipper pegs in your tranny?

Oh, and I'm almost done with my E-Maxx tranny install, I'll get some picks up soon. I just need to size and cut the drive shafts to the proper length, and mount the shifter servo (ugh).

Whats the advantage of running Maxx drive shafts?

ProjectTwin

12-24-2001, 12:18 AM

Hairball,

I need to order some slipper pegs...I'm also going to get the 76 tooth spur. While I'm at it, I'll order some Robinson pinions.

Advantages to Maxx driveshafts...

Will compress/extend as much as you want them to. The stock TXT driveshafts compress/extend about 1/2" only. Maxx sliders will go as far as your suspension will stretch them.

The BIG advantage is cost and availability. TRA4951 is available pretty much anywhere.

Got my TXT-Maxx running last night. Felt a little funny to be honest. I think the gearing is off a bit.

The biggest thing I noticed was that it was quiet. Almost no noise compared to the old tranny.

I havent got the extra sevro mounted up yet, so I can't shift into high gear right now. I'll soon fix that though.

Merry X-Mas Everyone.

P-Twin - WOW! Nice work bud. What did you use to cut the plexi-glass?

I think once you bolt it all together, that rig belongs in the readers rides section of RCCA. :) Maybe you should have used colored plexi. Transparent Blue TXT-1 anyone?

Its funny that you made a new top plate / "radio tray", I was doing the same thing last night, and out of clear lexan at that! I needed to redesign the radio tray to accomadate my extra servo and extra channel unit (Ko Propo gear). Now I just need to run the cable / push rod to the tranny so I can shift between high and low gear. Woohoo!!!

What to modify next? :D :cool:

12-27-2001, 11:29 AM

Dunaway18, the Super Rooster is only supplying the Monster Maxx motors with 12 volts(If you are running 10 cells), which is not enough volts for the motors. Those motors are made to handle 14.4 volts, and run their best at that voltage.

Doctor Doug

12-28-2001, 04:21 PM

Anyone try a single 550-size motor run at 14.4 volts in their TXT? This should still provide plenty of torque and top-end speed, but your run time will be greater than using two 550-size motors. And, yes, the EVX works with a single motor. I am going to try a Traxxas EVX ESC (14.4 volt) with "one" Trinity Monster Maxx Wild (19-turn) motor in the near future :D

Hairball

12-28-2001, 08:11 PM

Jeep tried just one motor once. Worked pretty well, just didn't have the "get-up-and-go" of two motors.

You'll loose a lot of the torque the truck has, which was the the truck was designed to have.... :confused:

Try it, and let us know how it turns out. :)

I just recieved a Novak Super Rooster for Christmas. I hooked it up in the TXT with 2 Trinity Chameleon 19 turn single motors. I wired them in parallel and I used 18 tooth pinion gears. Not a whole lot of torque and the top end is not that great either. I am looking for more top end but still want some torque. I was thinking of goin to the Trinity Speed Gem 16 turn triple with the 15 tooth pinion. Does anyone have any ideas about a motor slash pinion gear setup? How should they be wired to the Super Rooster in parallel or series? Has anyone seen the big brush conversion for the Trinity Speed Gem motors? There was an article about them in February issue of R/C Car Action Mag, but I cannot find them anywhere.

What can I say? I spoil myself rotten I suppose. :) You'd actually be surprised at how cheap you can pick up a simple milling / drilling machine like mine. It's not a percision tool by any means, but for simple tasks it works GREAT! I just wish I had room for it down here in Oceanside. :( It's back home in Sacramento....

The cable works pretty well. I was actually surprised at that it actually worked in the first place. I ran into a snag though. My Ko Propo EX1 Mars doesnt have end point adjustments for the 3CH, so it "over-shifted" and binded the linkage pretty good. Still works, but puts a strain on the servo.

After a little research, I realized that my Ko Propo EX-11 Presto (4Ch FM Radio) actually has programmable end points on it, so I just need to set it up to get everything working right.

But check this out, I had a brain storm while reading my Presto's manual. You can set a maximun of four "stops" for channels 3 and 4. So, I was thinking about getting another high torque servo for the rear stearing pod, hooking it up to channel 4, and then I'll have selectable four wheel steering. I know it won't be perfect, but it'll still be cool. :D I can also set channel 4 to be "linear" where it has 260 stops, one for each press of the button (its a 2-way switch).

Too bad it doesnt have channel mixing like a JR R1 does... Hmmm. But the R1 is only 3CH. DOH! Maybe I'll try it anyway when it gets here next week. :)

I guess 14.4 volts it like WAY too much for these motors. hehe

Off to the hobby shop to get some E-Maxx Titan motors.

Hairball

12-29-2001, 04:24 PM

Well, the bad news get worse. :(

My EVX is ok (whew), but one of my brand new Trinity 3000HV packs is dead. Straight smoked. There goes $75 down the drain.

**UPDATE** (Dec 30) **Update**
3000HV Pack lives! After cycling it a few times, its back up to specs, or at least close enough to make me happy. I just bought some single cell clear shrink wrap and re-wrapped each cell due to the original shrink getting all screwed up. :)

It took about 5 cuts to get the comms back to normal. The Brushes actually melted onto the comms, causing them to short, and I think thats what killed my pack. I think the only reason the EVX survived was the cooling fan I had mounted on it. When I got the the truck it was HOT, I mean way hotter than any ESC should ever get. Buts it lives, so I guess its all good.

One endbell on the motors is gone (the one in the pic above). The other looks ok, but I'm not sure its worth messing with again.

I'm beginning to see why Traxxas used 550 FAN COOLED motors. :)

Now I just need to find some.

12-31-2001, 08:19 PM

Well, if you're looking for a truely Unique truck, and want everyone that sees it ask you a million questions about it, get a TXT-1. Its got awesome torque and climbs better than anything else out there.

Whats your budget for this project look like? And how much work are you willing to put into it? I'm not saying it needs work, but a truck this cool has so many possibilities!! :D

But on the other side with E-Maxx's as low as $300 RTR these days, they are a great bargain!

The TXT-1 will set you back quite a bit more to be honest. ;)

bluesy

12-31-2001, 10:46 PM

I've got both of the trucks you are considering. The TXT-1 has a ton of "cooool" factor going for it as well as climbing "virtually" anything. The E-Maxx is cool in its own right but everyone and his kid has one, so they aren't so unusual. The E-Maxx is far better that the TXT-1 for pure speed but doesn't climb nearly as well. BTW, both vehicles I have are stock as far as the motor-drive train are concerned. If I were making the decision now that I made a month ago I wouldn't have purchased the E-Maxx. I would spend a little more money on the TXT-1. hope this humble opinion is of some assistance. :cool: :cool:

The stock motors hold up alright running at 14.4 volts. Try and get some heat sinks on them though, as they will get HOT !!!

And be sure to give it lots of cool-down time between runs. Or else you'll end up with some nice melted motors like me. :D

You can get the EVX cheaper from www.hobbypeople.net.

I would get a higher torque servo than that, at least 100oz. I'm using the Hitec HS-5925MG Servo, and Jeep uses the one above that for 150oz of torque.

And save money and buy stock emaxx motors, the Titans. The Trinity 550 motors wear out too quck and just arent worth the money. If you have a lathe that will cut 550s, will then MAYBE they are worth it, but its still a long shot. The stock emaxx motors are still way cool, and only like $20 a piece.

And what do you need the standard servo for?

Fetztang

isnt that servo like 130 or more at 6v. the standard servo was an accident i was thinking that i need one for the msc but i already had the evx. also i can get an evx of ebay for like $70. right now if i had the money there is a txt-1 with a radio a super rooster and other stuff for like $330

Fet - No problem at all, happy to help!

I still havent figured out the gearing for the E-Maxx tranny install in a TXT-1, but I can say it is much stronger. If you plan on running anything lower than a 23T motor (and thats even pushing it in my opinion) the stock tranny won't hold up. I blew two sets of gears in the stock tranny (The third set was getting ready to give, has wear marks on the teeth).

I wanted to play with my truck, not blow gears every fews runs and tear it apart. The E-Maxx tranny is built strong and can take one heck of a beating. As far as it being a two-speed, well, thats just an added bonus. :) I had mine locked in 1st gear (low gear) for the first few runs, and it worked just fine. Being able to shift it from the transmitter is cool, and gives it a bit more top end, and in reality, once the TXT-1 gets going that fast its not really stable, trying to turn it on a high tractaion surface results in a roll-over about 85% of the time. :(

But its still cool. New Era Models is going to be realeasing a conversion kit soon to install a E-Maxx tranny in a TXT-1 with bolt on parts. I made mine out of aluminum stock. Machined to fit. :cool:

If you have anymore questions or need help getting a Maxx tranny installed (Like servo linkage hookup, or mounting problems, the parts you have to *modify* to get everything, etc) please ask!

How is the TXT-1 stock? I just sold my XXX-T, and my KE XXX is on order but I can still have it canceled. I'm been thinking about monter trucks for the last couple weeks and I'm thinking of getting one instead of the buggy, but it's pretty pricey. If I was to get the TXT I would trade in my Cyclone 2 for an EVX, use one Panasonic 3000 or two 1500s.

Are the stock motors okay? I wouldn't have money for 2-3 months for upgrades. Also, I should use Titan motors instead of the stock motors or save up that money for some Speed Gems? Thanks for your help.

skribble you realy should get a esc and motors unless slow is all right for you(i dont really know but i read like this whole thread:D )

hey project twin didnt you make some ladder braces out of lexan? how are they holding up?

Yes its slow stock, but monster trucks are supposed to be slow. They just climb over stuff like its cool. :)

Its not hard to speed up though.

As far as "must have" upgrades, an ESC is a must. A high torque servo is a must. And motors above the stock ones are mando for the fun factor.

You don't need really fast mod motors though. Like 23 turn mods would be perfect.

Nice work Jeep. Saved about $20+ on those. :)

Do you have a lathe that can cut 550s? I've read the wear like Trinity D4s, so they need to be cut like every 4 - 6 runs. Should give you a TON of power though. (And I've got a spare gearbox for you when you blow your's to peices!!) :D :D

So are you enjoying your EVX yet?

Hairball

$20 total I think. They're $49.99 a peice from Tower. Plus shipping I suppose.

I'm not really sure what lathes will turn 550s, but if you're planning on spending some cash I would get a Hudy or a Fantom.

I'll post more in a bit, my wife is dragging me from the computer at the moment to grab some food. :)

jeep............. you who counsels others not to let your significant other in on your spending plans..... seeking rationale from others...... the "blue moon" must have risen last night.

JK man, If your existing lathe is old and worn out it MUST be replaced.

"Replaced with what?", she might ask.

"Why, my darling, when you chose me you showed your preference for the BEST.... so the BEST must have the BEST".

Any further advice can be obtained from Dr. bluesy (at minimal cost).....LOLOLOL...... :cool: :cool:

BTW, I am keeping my 19 turns in for a while. I want to see if Hariball's problem is replicatable.. No offense good buddy Hairball, but I think preventative maintenance might be the key here. Another reason for not putting in the new motors is that I do not yet have a lathe that can turn them. Soon, I tell myself, soon ... :)
The replacement EVX is working. I selected the 25% reverse profile. Not real impressed thus far. Resolution sucks on the low end. I just won a Tekin G12c on Ebay ... it just might find it's way into my TXT-1 if this EVX continues to not impress me.

Preventive Maintenance on what? I take great care of my TXT-1. The motors melting down was probably my fault, not cutting them as much as I should have, and running then at twice there rated voltage didn't help much either. :)

But that doesnt explain 2 (and the third was getting ready to go) sets of gears in the gear boxes dieing on me. The TXT-1 comes with 540 stock motors for a reason. Thats all those gears can handle for very long. It's almost like they were designed to go out, so Tamiya could make money off replacement parts... :D j/k
I installed full ball bearings in the gearbox, so overheating was not likely the cause.

And congrats and the Tekin G12c off ebay, I've got one too (a G12C III) that I was thinking of using, but I think reverse is more important. :) Getting stuck on a rock, then having to walk over and move the truck my hand is no fun.

And speaking of ebay, I just bought two stock E-Maxx motors. I really feel these are going to be the ticket. FAN COOLED 550s to go with my groovy E-Maxx tranny. Lots of power, heat problems addressed and hopefully taken care of, and motors designed from the get-go to handle the 14.4 volts the EVX puts out.

As always I'll have a full review of my finding once I get it all together. :) Oh, and I just got my GPM Racing Oversized 4 inch shocks in the mail today. I'm going to install them in the morning, I'll have some pics up as well. :) :cool:

You know guys I just have to say this... This is one of the coolest threads around here. Even though I don't even really want a TxT-1. This one of the only long threads that I actually read all of... Now lets see some action shots (of the TxT-1;))!

I'm running a Super Rooster right now, and will be using a couple of Magnetic Mayhems. Using the EVX forces you to run dual batts all the time, not so with the 'rooster.

Mag Mayhems are also 550's, 22 singles I think. :)

...and only one batt per run.

I know the speed won't be as great as with an EVX set-up, but if I want speed, I'll run the EVX powered (Soon to be Brushless) Juggy. TXT, to me, is a better low-speed crawler than an all-out speed vehicle.

And for you guys considering buying the Trinity Pro 17 singles...The motor limit on the EVX is a 19 turn 550. I ran the pros on the VX12 (which never died on me) and I actually preferred the Titans to the pros. The wilds I ran on the E in Augusta were a better set of motors than the set of pros I had.

Thanks Mason. :)

When I get my Titans installed next week, maybe the wife and I will head down to the beach with the digital camera and get those action shots you asked for. :cool:

Here is some more pics as I promised. They arent *action* picks, put I'll get those soon enough. :)

This first shot is some heat sinks I installed on the motors. These were the biggest ones I could get to fit with the Maxx tranny installed. Remember folks, heat is the enemy!

And this shot is my new GPM Racing Oversized Threaded Shocks. I think they were designed for the Maxx trucks, but they work nicely on the TXT-1 as well. If you look closely, you'll notice I had to hack up the center shock mounts a little (basically cut off the outer mounting holes to allow access to the inner mounting holes)
