I'm using a Roboteq controller in R/C mode to control two wheelchair motors in a tank configuration. Works great. I have a servo operating on a 3rd channel. I'm using a Spektrum Dx6i. It's been a while since I touched this robot. Everything was working. Now tho, the servo has stopped responding diceus.com/python-developers/
but emits a high pitched whine when power is turned on (it has a separate battery power supply)
Any ideas what's going on? Not all that familiar with servo troubleshooting. *One note, I can't really see the servo or get to it without dismantling a portion of the bot. I can, however, see the unit it's supposed to be turning.
