Trying to find out setup for grip driving for Traxxas Rally VXL standard configuration.
From the box, the car is spinning all the time, which may be its purpose, but I cannot handle it.
As proposed in manual, I have changed front and rear differential oil to 10k. I have 2 degrees camber, as well as 2 degrees toe-in both in front and rear. Now the handling seems to be fairly balanced, when cornering, I can control understeer with throttle. The car will accelerate to straight line quite easily.
The main problem left is when lifting the throttle (even without braking), the car will spin out very easily. I tried to loosen the slipper clutch 1,25 - 1,5 turns hoping to have less braking power in rear, but that did not help me noticeably. Maybe I have to loosen it even more. Even just turning the car too much with high speed (without changing the throttle), sends it to spinning out (rear of the car gets loose).
Perhaps I need center differential? What benefit it could have?
Or maybe this car is purposely heavyweight in rear and I must sell it and try something else?
