I am using a special body for my evo III - can the rear body posts be mounted on the chassis (i will drill the holes) or will this affect performance or cause the body to roll.

I'm a die hard Tamiya belt fan, have a ta03,04, and m2 but wen i saw the evo3, using m2 suspensions, got me wanting one, but when i saw that motor mount again, it changed my mind. Why dont Tamiya make the motor mount easier like the TC3, its evo3 already and still they didnt change that motor mounting, maybe on the evo4, hoping.....

Yes I agree..TC3 motor mount is the best I've seen.
Even on the upcoming HPI Pro4...motor mount is similar to the EVO-III.

anybody have those part # for the diff gears that keep on stripping...

50979 TB EVOLUTION III ONE WAY GEAR
If anyone is planning to buy the Evo3, make sure you get a few of these, you will need them.


Does anyone know why David Jun runs his Evo 3 with a raised (2mm) rear roll center??? Thinking of trying this out but would like to know the idea behind it.

Raising roll centers lessens chassis rolls on corners. When you lessen roll, you lessen weight transfer from inner wheel to outer wheel (this is during cornering). Lesser normal force (weigh on a wheel) equals less traction. Overall, your chassis starts to slide around sooner.

Usually this is done to add steering. Raising the roll center is similar to installing roll bars...

I have found with rasing my roll center on my TC3 that it helped the car rotate better mid corner. It seemed the same entering and exit just rolled better in the middle of the corner.

Jun's car has 2mm raised roll center in the rear. I believe the front is stock. Also, he moved the upper shocks to the outside position and is running 40weight oil I believe.

Did some test runs today with the Evo3 and got the car to turn much better through the tight infield at Socal. Unfortunately, I roached the front gears and will have to do a rebuild before I take it out again. When i disassembled the front gear box, I noticed that the four screws holding the gear in place have backed out. Did anybody else experience this? Other than that, the car is almost dialed, it's the nut behind the wheel that needs help.

Exclamation screws

That is why your gear failed.The one way screws loosen aand that extra play when stressed causes the failure.The tolerances of the front box has to be perfect.....When you take a hit in the front and power is applied,then your gear strip or break teeth.Been through 3 already.Finally got it figured out and haven't had a failure since. I race on carpet with some pretty unforgiving track rails.

What's wrong with Evo3's motor mount?
