is this possible?

i remember seeing something along the lines of a ring that you put onto behind a spinner/propeller that had magnets or something in it and it hooked to some kind of coil to charge the receiver battery.

has anyone thought of doing this with a weedie engine? possibly the rear crank stub of an echo or something?

EDIT: im referring to the sullivan genesys system

i think it a neat idea and have thought of it myself but i gave up due to the fact that........er....well i dunno but i jsut didn't do it, too much voltage varing from engine speed?

It is possible. You'd need to know the maximum output voltage and use a simple voltage regulator preceeded by a rectifier bridge.

EDIT: I remembered you can also use a used stepper motor (taken out from an old printer, for instance) a generator

i thought stepped motors had a stopper so they acted very much like a servo???[&:]
i used to have one.

but i just put a 12v 540 motor in the drill press at 3600 rpm and it only got 2v[]

Do a search for "longest RC flight record" you will find a about onboard chargers and fine tuning engines not to quit and be very fuel efficient. Capt,n
