Trying to burn in new Servos which I do on all of mine by letting them run in auto mode (which is continuously running from stop to stop) for about ten minutes each and also test crashed servos this way, is a major pain by trying to use a Rx. Best to get a real servo driver which can be had for as little as twenty bucks.

I have caught a number of bad servos both new and old by this burning in procedure.

A good driver is also invaluable in construction and installations of controls etc. Neutral can be found without the bother of hooking up a rx and runinng a tx.
