I am converting a 1.2m chuck glider to a rudder/elevator/motor glider. The glider itself has an empty weight of about 150g. Add two servos, Rx, motor, ESC, spinner, folding prop, 2S lipo it will probably reach 350~400g.
What sort of motor/esc/prop/lipo combination would I need for this, keeping in mind I need to keep it as light as possible?
