Folding 12x8.5 Electric Prop APC AP1285F  [AP1285F]

Performance and glide benefits

This APC AP1285F folding propeller pair is built for electric-powered RC gliders and sport aircraft that take 12x8.5 props. By folding while the motor is idle the blades reduce parasitic drag, then reopen to provide thrust when the motor spins, enhancing glide efficiency and cruise economy for electric sailplanes and sport flyers.

Installation notes: mount the blades to a compatible folding hub or spinner used with electric motors, ensuring the hub seat and any shaft adapter match the prop bore and motor shaft. Verify blade rotation and lock engagement before flight. Balance the set on a prop balancer to avoid excessive vibration reaching the motor and airframe.

Tuning and role: blade diameter and pitch will change climb and cruise traits; the 12x8.5 dimension is a compromise between thrust and efficiency for moderate-power setups. Folding props are typically chosen for self-launching gliders and electric sport models where reduced drag during glide segments is advantageous.
