2-PITCH HUB for ELECTRIC FLIGHT
A fixed pitch propeller compromises flight performance of R/C model aircraft just as it does in full-scale aircraft. For best takeoff and climb performance a low-pitch propeller is desired. For efficient cruise performance and high-speed a high-pitch propeller is desired. 2-Pitch Hub removes the performance limitations of a fixed pitch propeller for R/C model aircraft.
Typical Flight with 2-Pitch Hub
For takeoff, advance the throttle quickly to full power and 2-Pitch Hub automatically cycles the propeller from high-pitch to low-pitch and holds low-pitch until you reduce the throttle. At altitude reduce the throttle momentarily. 2-Pitch Hub immediately cycles the propeller to high-pitch. Increase the throttle slowly (from slow to fast in about 3 seconds) and 2-Pitch Hub holds the high-pitch setting. 2-Pitch Hub requires a little experimentation in technique and adjustment but will add performance and enjoyment to your flying!
Features of 2-Pitch Hub
Uses standard folding propeller blades (8 mm hub diameter) as available from Graupner, Aero-Naut and Robbe.
Allows for quick and simple pitch changes. One screw adjusts the hig-pitch setting (0 to +10 degrees) and one screw adjusts the low-pitch setting (0 to-5 degrees).
Requires no extra servo for pitch changes.
Weighs only 45 g (1.6 oz) and manufactured from a variety of metals.
Is easily adjusted for a wide range of use-prop diameters from 9 to 14", direct drive or geared motors, motor inputL 100 to 700 watts, and slow or fast airplanes.
