How to find the right RC Vehicle Propellers AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in RC Vehicle Propellers
- Diameter × pitch
- Stay at or near the size the motor or manufacturer recommends. Raising diameter or pitch raises current draw. An oversized prop overloads the motor and ESC.
- Rotation direction
- Match the CW/CCW or normal/pusher designation to motor rotation and position. Multirotors need matched pairs. A wrong-direction prop pushes air the wrong way or won't lift.
- Hub / bore fit
- Match the shaft diameter or mounting pattern (prop adapter, T-mount, shaft thread). Boat props must match drive dog and thread direction. A poorly seated prop vibrates or spins off.
- Blade count and material
- Boats use stainless or beryllium-copper for durability. Aircraft use composite, nylon or carbon. FPV quads use polycarbonate. Material governs efficiency, flex, and crash survival.
- Balance
- Balance aircraft and boat props before use; FPV props are usually used as-is. Imbalance causes vibration that damages bearings and video.
Brands that matter
- APC: Long-standing fixed-wing aircraft prop maker.
- Master Airscrew: Aircraft props including folding options.
- Gemfan: Common FPV multirotor props.
- HQProp: FPV and multirotor props.
- Octura: RC boat props.
- Pro Boat: OEM props for its boats.
What to avoid
- Mounting a prop backwards (the lettered or curved face normally goes forward)
- Chipped or cracked props
- Upsizing a prop without checking motor and ESC current
Questions
What do the two numbers mean?
The first is diameter and the second is pitch, the theoretical forward travel per revolution.
