APC 12x8.5 Folding Propeller Blade Set
APC 12x8.5 Folding Propeller
APC Folding Props are great for applications that require short bursts of power, with extended periods of gliding in between, such as Electric Sailplanes, Motor Gliders and LMR (Limited Motor Run) type models. When the motor is turned off, the airflow folds the prop blades up against the aircraft fuselage reducing the prop drag for more efficient gliding flight.
According to APC's published Maximum RPM formula of 120,000 ÷ D for APC Folding props, the 12x8.5 prop should not be used over 10,000 RPM.
Please note, this package only include a pair of blades, as shown in the photo. To complete the prop, you will need to purchase the APC-FH45mm-6 folding prop hub kit
