Gemfan GP2219-3 – three-blade propellers for GEPRC DarkStar22

Gemfan GP2219-3 is a propeller for small FPV drones, jointly developed by GEPRC and GEMFAN. Manufacturer-confirmed compatibility with GEPRC DarkStar22 makes this set suitable for replacing that aircraft’s propellers or keeping as spares. Its construction combines three blades, an ultra-low pitch and two-screw mounting.

55.9 mm diameter and polycarbonate construction

Propeller diameter is 55.9 mm, approximately 2.2 inches. Each propeller is made from polycarbonate, also known as PC, and weighs 0.8 g. According to GEPRC, its ultra-low pitch is intended to support smooth, stable flight. These specifications define Gemfan GP2219-3 as a replacement propeller intended for DarkStar22, with dimensions and construction specified for that application.

Three-hole mounting pattern with two-screw attachment

The central mounting hole measures 1.5 mm in diameter. Two screw holes sit alongside this central opening, allowing attachment directly to a motor rotor using two screws. GEPRC has optimized this arrangement for upright motor configurations. For use on another aircraft, check propeller diameter clearance, motor shaft compatibility and screw mounting compatibility; a matching shaft diameter alone does not establish full compatibility.

Four propellers in two rotation directions

Each pack contains two clockwise CW propellers and two counterclockwise CCW propellers, giving four propellers in total. During installation, match each propeller to its motor’s rotation direction and use a suitable screw attachment.
