I think the drill will turn too slowly. If you don't have everything you need to make your own (r/c car battery,charger, motor, switch) I would buy a Sullivan 1/2A starter.

I made one from parts that I already had and used a motor from an old dustbuster...all I had to buy was a horn button switch. I made the prop cone with a wood paint brush handle (foam brush)and some 1/2 inch rubber hose over that.
It works great!

BTW: The picture shows up as the actual size on my computer!
