Product overview
The Gemfan 45mm-3 is a three-blade micro propeller intended for indoor Tiny Whoop racing. It combines a 45mm diameter with a 1.5in pitch and a weight of 0.43g. Its PC construction provides toughness for frequent collisions and high-RPM operation, while the blade design emphasizes grip, thrust and fast response during racing maneuvers. Compared with the two-blade version, its three-blade structure provides stronger thrust, quicker acceleration and higher top-end speed for competitive indoor racing.
The propeller fits the 80–85mm micro quad class, with an indicated quad weight of 80g and a recommended 0805 motor. Mount options accommodate 1mm and 1.5mm motor shafts. The package contains eight propellers, divided into four clockwise and four counterclockwise units. Color selection depends on the mount size: Clear Gray, Macho Pink and Blue are offered with the 1.5mm mount, while Clear Gray and Clear Red are offered with the 1mm mount.
