There's a guy at my flying field who has a small starter with gear reduction that does the trick too...we call it "the little starter with a big heart".
If you use the Miller reduction drive the 3/1 reduction reduces the current required by the motor so you can use a standard Sullivan motor on 24V. You do not need that expensive Dynatron.
The OP meeds to increase the voltage to the 18V maximum permitted by his unit
