My buddy replaced his titan with a 15 turn, which i believe is the limit for the xl5, and the damn thing keeps shutting down.... Geared correctly, motor not hot, esc not hot, run anywhere form 5 seconds to 5 minutes....and just shuts off. Steering still works, lights on esc still com on for foward and reverse, but nothing out of the motor. Motor is fine, tried in another car, worked. Another guy at the track had same problem in his slash, tried a 19 turn, shut down as well.....dont know about this esc
