Gemfan Flash 5144 Propeller (Set of 4 — 2CW+2CCW)

The Gemfan Flash 5144 is a three-blade polycarbonate propeller engineered for 5-inch FPV racing and high-speed freestyle builds. With a 5.1-inch disc diameter and a steep 4.4-inch pitch, it provides exceptional top-end speed, rapid thrust generation, and responsive grip through tight turns when driven by 2205 to 2306 brushless motors.

Key features

• Aggressive 4.4-inch pitch profile optimised for top-end track speed and high-throttle authority
• Moulded from impact-resistant polycarbonate blend to resist blade deformation and shattering during gate strikes
• Standard M5 hub bore fits standard 5-inch FPV motor shafts without prop slip
• Balanced airfoil geometry designed to maximise thrust on 4S and 6S powertrains
