The rod rod is 4/40. It is heavy but there does'nt seem to be any binding. You can open the throttle by hand and the throttle spring returns it when you let go. I've opened the other two servos to see if there was any gear dammage and there wasn't. It seems like the servo motor itself is getting cooked. You cant budge the servo arm. I guess since the Hi-Tec 645's are holding up I could replace it with one of those. How imprtant is it to balance the Life battery when charging it.

Thanks,
