I've put a 12s system in my XRT and have tried both belt drive and 1.5 mod gears. Yet I can't keep my grub screws from rounding out on the motor drive shaft. It seems to be just to much for them to handle. The only other option that comes to mind is drilling through the drive shaft and using a post like the transmission shaft. Any thoughts?
