Gemfan 45mm-3 3-Blade Propeller 1.5mm Macho Pink (4CW+4CCW)

Gemfan 45mm-3 3-Blade Propeller 1.5mm Macho Pink (4CW+4CCW)

Product description

The Gemfan 45mm-3 3-blade propellers with a 1.5-mm mounting are designed specifically for Tiny Whoops and micro FPV drones. With a diameter of 45 mm, a pitch of 1.5 inches, and their 3-blade geometry, they are designed for powerful thrust, rapid acceleration, and responsive handling. Gemfan recommends these propellers specifically for indoor Tiny Whoop racing and 80–85-mm micro-quads.

According to Gemfan, compared to a 2-blade version, the 3-blade design generates more thrust, faster acceleration, and a higher top speed. This makes the 45mm-3 particularly suitable for small FPV drones that require agile and performance-oriented flight characteristics.

Weighing just 0.43 g per propeller, the rotating mass remains very low. This supports rapid changes in RPM and a spontaneous response to throttle commands—which is quite helpful when, during indoor racing, a doorframe suddenly appears with a surprisingly aggressive ideal racing line.

The propellers are made of durable polycarbonate (PC) and are therefore designed to withstand the typical stresses of small FPV drones. This version features a 1.5-mm motor shaft mount. Gemfan recommends these propellers for 0805 motors and specifies a recommended quad weight of approximately 80 g.
