This APC AP1285F folding propeller set is made for electric-powered RC gliders and sport aircraft that accept 12x8.5 props. The composite blades fold to cut drag while the motor is idle and reopen to deliver thrust when the motor spins, improving glide performance and efficient cruising for electric sailplanes and sport models.
Installation notes: fit the blade pair to a compatible folding hub or spinner system used on electric models, ensuring the hub seating and shaft adapter match the prop bore and motor shaft. Check blade direction and secure locking mechanism before each run. Balance the assembly on a prop balancer to minimize vibration transmitted to the motor and airframe.
Tuning and role: blade pitch and diameter influence climb and cruise behaviour; the 12x8.5 designation provides a balance between thrust and efficiency for moderate-power setups. Folding blades reduce drag during unpowered phases, making them common on self-launching gliders and electric sport planes where lowered drag during glide is beneficial.
