Well I was thinkin the other day (I know my Dad told me not do cause it was dangerous) but Team Losi and Sportwerks (both R/C Car specific brands) have a direct drive starter that uses a 550 motor and a 7.2 volt battery and has a 6mm starting shaft...
From the times I've used it on the truck it has LOADS of torque, I dont think it would have any problem turning a 30 or 50 Heli engine...
Heres a Link...

that would work just fine as long as the end was the right size
Its a 6mm shaft isn't that the right size??? Dont know about the 60-90 range but it fits the 30-50's fine

Won't work pal,
The starters for cars turn to the right, you need to start you heli going left.
I was way ahead of you when I bought my Mayhem, but the starter that comes with it turns the wrong direction.
On a plane or heli, you are applying the starter to the "front" of the crank, where as a car, the starting point is at the rear of the crank.

scott is the man, i didnt even think of that
Just reverse the motor wires, lol it'll turn the other way...
