the speed controller dont lock the beeps on the trim tab when triming to a CONTINUOUS beep.. also it was checked with my U-can-do and there was no movement when locked up it has to be cut off and restarted to get the annoying flatline sound to quit and regain function. It is POSITIVeLY my controller. I dont trust it anymore after that.. i am sending it back to hitec for repair and selling it after i get it back.

Im still pretty ticked ,the plane flew so well too. and it ruptured my battery ruining it..
