I just came up with the concept took the assembly out of a hand crank charger for phones i got off ebay setup is pretty flimsey right now but i hope too make it better. will post some pics up soon. I will try a test to get a voltage reading amperage ect.
 
Here are some pics of it

I'd be concerned about making sure you have a consistent voltage/amps if hooking it to the receiver. What you get may rise and fall with the engines RPM's and you don't want to fry the receiver.

As far as hooking it up, looks like you could use something similar to what superchargers use.
 
Good idea. Like mentioned, find a way to regulate it. I 'd just start with lights first. Rx's and servos could get expensive. Keep us updated.
 
mabe you could hook it up like a normal car. charge the battery with it. find a way to hook it to your reciever pack and you will never need a recharge again
 
google lm338 like r/s lm317 but handles more amps. note: the package that r/s lm317 is in , the diagram is wrong.
 
Considering the gear reduction you have there... my guess is that the engine is going to spin the guts out of that generator. 5-6:1 from the CB to the shaft of the generator. Even conservatively to say the bell will spin at 10K RPM's, that's 50K on that generator. My guess is that it's not quite built for that. ;) You may want to figure out a pulley on that input shaft to make it at least the size of the bell area the bands are at if not larger.

An easy way to test it would be to try it on a dremel. If you have a variable dremel, I think it has the rough RPM's on the switch.
 
Interesting concept. One idea would be to use something like an LST clutch bell, with the dual gears. Or if you know somebody who can do it, make a geared flywheel.

If you can refine it to charge batteries at a constant rate, without damaging the batteries, you could sell alot of these. Make sure you patent it.
 
I've seen them, but they were for planes... not sure why they exist since we get so much run time these days out of a decent pack. May have been for back in the old days when NiCAD was all they had on a 6+ servo juggernaut of a plane.
 
Tried it today i need to find some kind of belt for it i was thinking of using an o-ring the rubber band didnt last a second????

That woul be sweet but then you would have to make some sort of mount for the motor that is ajustable
 
I also ha an idea like this but thats another story
