Hello again! The motor is the Speed 280, which with its 2.5 to 1 gearbox, is included with the Mini-max. The receiver is the GWR 4P by GWS, and the speed control is the Great Planes C 10 Micro.
The spec sheet for the receiver says, if I am reading it correctly, that the operating power is 4.8-6.0 volts, and current drain is 5mA. Sensitivity is 5u volts.
Indications for the speed control are that it can stand input voltage of 5 to 8 cells, and up to 12 amps Max rated current. Do you think I am safely within these limits?
Thanks again for your quick response! Glen Priest
