Giant Scale Twin Question

[Paul Eagon]

I am in the thinking stage of converting and Wendall Hostetler Cessna 337 Skymaster to electric using two Hacker A-60's.

My question is concerning the rear pusher motor.

Would the thrust be sufficient if you install a regular prop in the normal direction then reverse the motor, therby pushing air.

This, of course, would alleviate trying to find a large pusher prop?

I know when you have a single engine plane and the motor runs backwards, air is pushed rather than pulled. I just don't know how efficient this action is.

Has anybody out there tried an electric pull-push set-up?

Paul,No problem.Just use any tractor prop and put it on backwards on the rear motor and that's it.Swapping any 2 motor leads will reverse the rotation if needed.It's one of the advantages of electric motors.
