Hello M9cat,

I know their hasn't been any activity on this thread in a while. I just happen to be looking through the "stickies" here and found your question about using a pusher prop on a front mounted electric motor for your Super Cub. You may have found that it works OK after reversing the rotation of the motor. The only problem would be if there is right thrust built into the motor mount. For a reverse rotating prop you would need left thrust to counteract the torque of the prop.
In fact, in the electric control line planes today, pusher props are preferred. They give better line tension.
