BD48 Hybrid System

I'm building a weed eater motor - dc permanent magnet motor generator for my BD48 kit.

Today I spent time on cutting and sanding the plastic weedeater housing to allow me to screw on aluminum angle to make a motor mount. The mount is pretty straight and stable, I think it will work.

For the dc motor, I cut out a mount from 1/8" aluminum plate scrap that I had in my garage. It will be fitted to some aluminum angle as well.

All this was done with a hacksaw and file, and an electric drill. I don't have good metal working tools, mostly just hand tools.

I still have to bolt a lot of stuff together, align it and mount it to a piece of plywood. Then add a gas tank, electric switch, servo and controller. I still have to program the controller, I may just start out with adjusting the throttle and holding it in one position at first.

Re: BD48 Hybrid System

Very cool! When I tried putting a generator in the basket of my trike, it was just too heavy. Top speed was just under 15mph. That should work well.

Be the pack leader.

Sounds like an interesting project. I think you can probably get away from that large of gas generator, but not sure. I wonder if the RC people have super small/super quiet gas engines...hmm. You may want to check with this guy:

They have several mechanical combiners and Dave Staton is a great guy to work with on custom jobs.
