as you guys suggested.... BEC!

email i got from CC about it.

Thanks all!

Michael,
Savox servos are notorious for their amp draw (which is probably why they do not publish their specs), and that is the problem here. The servo is simply drawing all of the voltage out of the receiver (and Spektrum receivers are a little too sensitive to low-voltage, and have been known to drop out a little early), leaving none to power the receiver and servo. An external BEC will definitely solve the problem. Our CC BEC 10A will allow you to run any servo you want, with accessories like a personal transponder or lighting kit as well.
