Discover Gemfan
Gemfan offers a wide selection of propellers for FPV drones, spanning small whoops, cinewhoops, freestyle aircraft and larger multirotors. Different propeller families provide pilots with options for fine-tuning the flight feel of an existing build.
Blade geometry, diameter, pitch and hub design all affect how a motor delivers thrust. Small changes can alter low-throttle handling, acceleration and efficiency, so the best choice depends on aircraft weight, motor configuration and the type of flying you intend to do.
Check the propeller's mounting hole, shaft diameter, recommended frame clearance and clockwise or counter-clockwise orientation before installation. Replace damaged props promptly and avoid assuming every propeller with the same diameter is interchangeable.
