Sounds like you are having problems with Turnigy products as well.
Wondered about their servos...I have had NOTHING but problems with their LiPo packs for micro to medium-sized electric R/C aircraft. Enough problems as to capacity and life where I have forever banned purchasing their products, and reccommend others do the same.
