Hi Maurice,

Man, you've got my brain all twisted up now. I scrolled down as you suggested.

I've looked at each drive system, found a patented system, and the patented system on the Short Scion.

Here are some screen shots:
Airspeed Envoy uses a simple angled approach, until you have to modify the prop shaft using a flexible piece of rubber tubing or some kind of spring glued to allow bending as shown in this screen shot. The Beaufighter uses a similar approach:

Now for the Beaufighter, two screen shots showing the similar connection, but has photo screen shot of flexible plastic/rubber tubing used:




The B-17 model screen shot:


Now for the patented shaft drive, boy this is complicated, it looks like the rubber band is inside the wing and not towards the tail for weight and balance:

Ok, the final model uses another patented system, talk about complicated, uses gears, and has an extension shaft to help with winding. The extension shaft is the "tin" tube part going towards the front of the model after the plywood gear mount. Here are several screen shots showing the system parts in detail:
This is the load bearing mount inside the wing


Here is the front mount, the brass extension with tin to wind it all with:








Plenty of options to think about!
