Help required please
We have recently moved to the XB4's running them in 4wd, I have 2 buggies both with 6.5t orca motors, orion R10 pro, I am running a 19t pinion on stock spur at surrey & Hants, however if the driving gets a bit aggressive on the throttle side the car thermals
. At both Silverstone & Telestar I ran 21t pinion and the same result. I moved to an 8.5t orion motor and it has been better but not 100%. Both cars drive trains are free with no binding with the pinion removed, Is there something in the meshing or the slipper I am getting wrong?
Any suggestions please
Thanks in advance
