Newbie here looking for help with a circuit for a generator to charge the battery on a large remote control helicopter.
Basically I'm looking to mechanically drive a brushless motor (3 phase) from the output shaft of the engine, rectify this and use a voltage regulator to supply 5.6v to my battery pack.This would allow me to fly almost continually (dependant on the petrol tank level) without having to worry about voltage dropping in my electronics.
I am an electrician by trade have soldering and pcb manufacturing knowledge from my apprenticeship, just cant remember anything about cct design!! it was 20 years ago so really I need a boffin who could tell me what components to use and a connection diagram.Any advice greatly appreciated.
