Colin & Don,
Thanks for your replies!
I am trying to build an on-board starter for an R/C Helicopter. Currently, I have to use a starter (like this one:
Hobbico TorqMaster 90) with a long starter rod to insert into a Hex coupling on the Helicopters starter shaft. When I power the starter, it spins the starter shaft. I would like a self-contained unit.
I am trying to find the smallest motor possible, due to weight reasons. The motor would only spin for a few seconds at a time, to turn over the Nitro powered engine.
I have clear horizontal access to the starter-shaft. I was wanting to build something like the on-board starter in this picture:
Notice the motor, gears, and plate next to the helicopter mechanics.
Thanks for all of your help! As a side reference, you can see the Helicopter that I am building here:
