Here is the issue when I have the car on the stand and slowly rotate the wheel the other wheel does not rotate in the opposite direction. Im assuming that means that I have it to tight. When I drive the car on my carpet it drives fine. When I try to do the lift test to set the clutch, the car will not lift. I also have thightened the clutch pretty much all the way. Is the issue the diff?
Are you holding the spur when you turn one wheel? most brushless motors don't have enough "cog" or resistance and you end up spinning the motor before the diff. When holding the spur you should be able to spin the wheel about one revolution with a good "flick".
