These manufacturers offer a great range of propellers for Glow Fuel Powered Aircraft. Master Airscrew Scimitar props and Radio Active RAM props offer the greatest efficiency. The boss is precision drilled to 6mm, so fitting most manufacturers Glow Fuel Engines. Consult the engine maker's manual to choose the optimum propeller size. We also supply a range of folding propellers to suit Electric Powered Gliders, these cleverly designed props fold shut against the fuselage of a model when the motor shuts down, allowing for the aerodynamics of the aircraft to take over. When coming in to land the blades are tucked away against the body of the aircraft, keeping them out of harms way.
