You need a small diameter motor for a large F5J model or a similar electric glider with a small nose. This is a hand-made solution, assembled in Australia using one of the best gearboxes available in the world - a Reisenauer mini! Ideal for saving wieght - get rid of the lead in the nose!

A Scorpion heli motor has been matched to the Reisenauer mini gearbox. This combination is capable of up to 4.8kg thrust for a short time with a 15x8" prop on 4S at 72A! Use a 15x6" on 3S and you pull 35A and generate 2.5kg of thrust .

Includes a unique system to keep the cables away from the spinning can - a spring is attached to the motor and supports the underside of the cables, pushing them up against the fuselage side. Because it locally engineered, service is available on this motor/gearbox.

Ideal for large F5J models of up to 2.0kg
