everybody has their favorite servos, lowteks always let me down. my aces and jrs have been running 2 seasons without issue 1. i like the idea of rotating the main gear, you only use like 1/4 of the wheel anyways. i always thought it could be some grease that seeped down onto the pcb affecting the centering chip thing. run it till it don't run any more then send it in for warranty, done.
