I keep twisting my half shafts off of my rustler. They keep popping off at the knuckles and its getting really old. Can I convert it to a dog bone or are there better quality half shafts that I should be buying? I'm running a velineon 3500kv with a radient reaktor esc on a 2s 5300mah. Its a 90t spur on a 20t pinion, lately I've been running on short course truck tires. I'll see if I cant get some pics up soon. Thanks.
