My tranny has been flawless bone stock. And I run a V-Twin on 3s LiPo much harder than most will. Never had a tranny failure.

Edit- Actually I did have a failure. I used a light-weight output shaft that bent and broke under the power of the dual VXL system, no gear issues though. If you want to upgrade, just go with some RC-Monster steel idlers and be done with it.

Well, the dual vtwin must not be as strong as you think. I have killed the roll pin on the top gear, broken input shafts, stripped lower gears, broken the 2 speed sliding dog clutch, and broken tranny cases. The rcm steel idler, and a gmaxx single speed are mandatory. Plus modding a revo input shaft to use the revo spec slipper on the old tranny is a good idea.

All of my damage was done with a single motor setup, 3s to 5s. God knows how many diffs I have killed. Now I have the lst diffs and the modded single speed tranny mentioned above and it can hold up to a 1515 on 8s lipo...

What KV was the 1515 you were running? What ESC?

I am running a lt10s esc, and an aveox 36/38/2, identical to a 1515 2y.

I am definately putting the tranny and lst diffs thru some hell. And I plan to gear up for stupid speed. Just need to put a decent body on it...

It holds up just fine if you drive it right. My Twin on 3s will outrun a 1D on 4s in a Revo, I've already done it. I'm sure you have seen my videos, the truck is plain fast and has too much torque. I use 1st gear at lower speed bashing and 2nd gear on speed runs and racing. If you have had bad luck building your trannies, thats no reason to say a Twin doesn't have the power. I run my truck very hard and it has yet to fail. Single speed isn't mandatory, nor even recomended if you ask me. A V-Twin really benefits from 1st gear at low speeds. I broke a roll-pin way back when the truck was a single VXL, replaced that with a bent hex key and its been off to the races ever since. My recomendation is go with the RCM idlers(I have a set I never installed because my stock ones have never failed) and replace them when your stock ones break. Here is my twin.

Bit contradictory...

I have to say that most who run brushless find the stock idlers wear out fast, or the teeth come off. Then when you throw in the steel idlers, the lower gears will loose teeth. Maybe you are not jumping the truck, or have the slipper set loose. Or you are running stock tires on a lower grip surface. I broke many parts, and so have a bunch of people. Run larger tires, jump with a tigher slipper, or just run on the street hard. I can break most things on the street, good traction and plenty of power will do that.

Plus, I would like to point out that if the velineon motors were that powerful, they would snap the 1/8 shafts. i do realize there are 2 of them... They are only feigao s can motors after all.

Smaller motors have less torque, and torque breaks stuff. Run a kb45 motor in something and you will see why they have a 6mm shaft...
