I want to do the same thing firefighter. An electric starter here in Aust costs around $120.00 and you need to carry a battery to connect it to. A GMC brand cordless drill is only $30.00 when on special and has its own re-chargeable battery. I was going to use a socket and fill it with silicone but as you mention "Starter hubs" I will try and get one of these instead. (I didn't realize that you could get a starter hub separate from the electric starter.)
I cant see why it wont work as its not as if speed is required to start the plane or using a chicken stick wouldn't work.
Thats my thoughts on the mater anyway, I'm now just waiting for them to come on special again at Home hardware.

Regards,

Troy.
