Boy am I confused. I thought I would put together a system and do a little electric flying so I started doing some research. The more I looked into motors, batteries, speed controllers, the more confused I got. Motors seem to be rated by volts and amps, Speed Controllers by amps and # of Cells, Batteries by volts and mAh and I have no idea how Transmitters are rated. Whats the trick? Whats the code? How do you know what goes with what?
