I love it when a free-flight pilot gets anxious about winding the motor! It's like they have all the patience in the world when it comes to retrieving the plane at the end of a flight, but they gotta get that fawker wound an in the air NOW! Why not 8:1?

Teasing, I love it. I wound a LOT of rubber bands when I was a kid, and destroyed many little balsa mosquitoes made of stick and silkspan.
 
What I wouldn’t have given for one when building balsa wood kit planes. Would have save my fingers. Nice project. Glad to see not every thing is radio control.
 
Volare had some that cranked out 10 to one. I dunno if they still have any or not.

It was developed by an 80 tooth bronze gear from England and an 8 tooth pinwire gear.
 
this brings back some ancient memories.
Your winder looks heavy duty like for bigger outdoor models?
Back in the day, I was doing penny planes and similar indoor models, so we had really small winders.
 
These were ten cents at any corner store next to the water balloons and cap guns when I was a kid. Ten cents means ten for a dollar, which is a squadron for an epic air war.

If you’ve got a 3d printer (I do!), this is a nifty little 15:1 winder to print. I’ll have to give it a shot and let you all know how it goes!
