cracked rotor on velineon

[dirt101]

definately not an xl motor. I have done that before and its just to much weigh on the back. makes the truck wheelie at 1/8th throttle. I have considered a 1506 or a 1509 but I just ordered a tekno 1515, MMM, and everything to convert my CRT. I really cant afford a neu right now. I have been looking at the 3300k/v 50mm medusa. is it pretty good? and how long is the velineon motor? I have also been looking at an 8L, but I just dont know yet
