Gemfan 40mm Propellers, Tri-Blade, 1.5mm Shaft — for Cetus Pro

This set of Gemfan 40mm tri-blade propellers is designed specifically for the Cetus Pro quadcopter and the Cetus Pro Kit. These propellers were created in collaboration with BetaFPV and are optimized for compact motor-axis solutions, particularly 1204 and 110X motors, ensuring stable thrust, precise control, and low vibrations on small platforms.

Design and Advantages

The tri-blade design increases lift while maintaining maneuverability and vertical stability, making this set ideal for rapid maneuvers and aggressive FPV flight. The blade geometry and quality material provide good resistance to impacts and bending with minimal weight.
