Been doing this long enough to have owned and used NiCad batteries, tray dischargers, motor lathe (with a tabbed motor option), and brushed motors with rectangular brushes! Shoot, I remember racing a...

Thanks fellas.

Here’s a riddle. What rattles, keeps your engine from idling even with the wheels off the ground, but stops rattling if you grab the heat sink head? If you said a rear crank bearing you’re a winner!...

Had problems with adapters in a friend’s UDR, but it was immediate, not after a month like yours. Would be worth borrowing a set with actual Traxxas connectors if you can. Just to test.

Put the batteries on to discharge and check the voltage under load. Won’t be as high an amp dar as your motor but might give you some useful info. Do you storage charge your batteries?

Looking good. What did you finally go with for steering servo?

Great info. Thanks, fellas.

Yes. Thicker, covers more, and is actually attached to the chassis.

My best guess from what you described is the original stripped gear problem came from a bad bearing. Did you ever replace those?

Given a choice between erring on slipper being too lose or too tight, I’d choose too loose. Easy enough to tighten on the truck if it is.

Download the exploded views from the Traxxas website. They have them for both the 2.5 and 3.3 T-maxx. They're a big help in seeing how the cars are put together. Then you have to decide just how much...

+1/ There's a learning curve with RC no matter how good a mechanic you are. Nitro adds even more. The 3.3 is a good engine. Run it and learn how to tune, then drop in a big block if you want. High HP...

When you install the new slipper adjust it so it takes some force to turn the spur by hand when you lock the shaft. Can fine tune from there after you put it back in the truck.

Heat shrink it.

4910 should have the 2.5 engine already. Unless it was used a lot the starter motor is probably ok. Spray it out with motor spray or electronics cleaners and oil the bushings, will probably work...

Glad you got it solved. Sidewinder is good fuel. I don't think you'll be disappointed if you try it. As an aside, after running one truck on 20% and one on 30% I've decided I like the 3.3 better on...

Laughing so hard right now. Friend of mine was working in AK for a bit and put studded tires on his 1/8 nitro. Things were great until he lost radio signal and it went WOT and turtled. He starts...

And in keeping with that theme, M2C clutches for the T-maxx and Revo are on the way. :D

If you haven't already, Steve Bess wrote an article years back about not being afraid of your mid-range needle. Good read if you haven't seen it already. He can tune.

Mr. Paris says leave that 3rd needle alone LOL! Unless you really know what you’re doing. I remember years ago someone (Thunder Chicken maybe?) made a MT with a ringed heli engine. A beast when it...

You don’t need metal gears for what you’re asking that servo to do. You can buy the replacement gears for $4.00. If that solves your problem, awesome. If not, I would just replace it with stock.

Hey mrtwohands, I talked to Mitch at M2C today and he has braces back in stock. As good a $20 as you will ever spend on your Revo.

Google Ron Paris "Tuning bible" and you'll find a post somewhere by a man that knew more about nitro RC engines than most people ever will. It explains a lot of what nebulous.cow is talking about....

Thank you, I did. Just need to pick out a new body, paint it and get his name on the passenger door and we’re done. Well, done as you get with an RC car anyway ha ha ha.

I don't know anything about Traxxas fuel. Long as you're seeing smoke on the top end you should be okay, but obviously the more smoke the safer. Sounds like you're a little rich on the bottom. Only...
