Product overview

The Gemfan 45mm-2 is a two-blade propeller for indoor Tiny Whoop aircraft and micro freestyle quads. Its physical design combines a 45mm diameter, 1.5-inch pitch and PC construction, with each propeller weighing 0.33g. The aerodynamic profile is intended to reduce drag and support responsive throttle control, smooth handling and precise freestyle maneuvers. Its application range includes indoor racing tracks and tight technical circuits, making it a propulsion component for compact quad builds.

Integration centers on 80–85mm quads, with 0805 motors recommended and mounting options for 1mm or 1.5mm motor shafts. The listed quad weight is 80g, while the lightweight application description specifies approximately 80g takeoff weight. Color choices depend on the mounting variant: the 1.5mm version offers Clear Gray, Macho Pink and Blue, and the 1mm version offers Clear Gray and Clear Red. The supplied configuration comprises four clockwise and four counterclockwise propellers, providing eight propellers in total.
