Roll - O - Plane shot 1

The Everly roll-o-plane model I built summer 2015 - you can see the gearbox on either side, the left side is for the 12v electric motor and the right controls the boom. The boom rotates, pivots 80º on its x axis and rotates the planes simultaneously off one power source with minimal strain on the motor.

There's another shot of it where you can see it when the boom is flat or "helicoptering"
