Roll - O - Plane shot 2

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.

This shot you can see the boom rotating or "helicoptering"
