Hi all. I had put my mini revo away for awhile. Bought some brand new **** 3s lipos for it...stock motor and stock esc, stock servo. I charged up batts and went for a run. Servo was acting goofy. Turns one way ok...the other is all jerky. Bought a brand new hitec 5085mg... same thing. It will turn sometime...most of the time its real jerky...wont hold when turned all the way. Could this be my esc? Maybe not passing enough voltage to servo? Would a new sv 2 take care of this issue?
