Get a Heli-Max with onboard batteries. Mine will turn a DA 50 with no problem. It's geared, with 2 motors and 2 batteries. I think the starter itself is only $39.95 and then the cost of 2 batteries.

Read the part about a DA 50. Do you know what a DA 50 is?? It turns mine with NO PROBLEM!! (Although I don't actually start it that way...just a test I did with it).
Edit: That was not meant to be as rude as it sounds. A DA 50 is a 50cc Gasoline engine which turns a 22-24 inch prop.
