Gemfan 31mm 1211 Drone Propeller 4 Blade (4 Pair CW+CCW)

Build note 01

Best suited to 1.22-inch builds that are tuned around this prop diameter.

Build note 02

4-blade geometry with a 1.1 pitch usually trades extra grip for higher load on the motor.

Build note 03

Check for a 0.8 mm shaft or hub fit before checkout so the pack lands on the right motor setup.

Build note 04

One retail pack covers 8 props, so confirm whether you need one full quad set or spares as well.
