Gemfan 1220 31 mm 4-Blade Propeller (1 mm Shaft) – Clear Yellow

Gemfan 1220 31 mm 4-Blade Propeller (1 mm Shaft) – Clear Yellow

Product description

The Gemfan 1220 propellers are designed for particularly compact FPV micro drones and Tiny Whoops with 31-mm rotors. With a pitch of 2 inches, the four-blade profile delivers powerful thrust and supports precise control responses during rapid changes in direction. The compact design is particularly well-suited for indoor racing and flight maneuvers in tight spaces.

The durable polycarbonate combines flexibility with a low weight of just 0.31 g per propeller. The low rotating mass enables rapid changes in RPM, while the four rotor blades ensure smooth power transmission. The 5-mm-thick hub guarantees a secure fit on the motor shaft.

The 1.0-mm shaft mount is designed for small brushless motors in sizes 0703 through 1103, as well as compatible coreless motors. The set includes four clockwise-rotating and four counterclockwise-rotating propellers in transparent yellow, providing everything needed for a complete rotor replacement.
