Hello. I want to use an electric motor on the plane I'm building (Herr P-51, 42" wingspan). It is going to use 3 airtronics servos (rudder-elev-ailerons), and my radio is an Airtronics Vanguard, 4 channels, with the airtronics FM receiver (receiver is 6 chans. I guess). What kind of electric motor would be good for this plane, and how to combine this motor with the 4.8 V of the Airtronics set?

Thanks!
