Gemfan 1636 40mm PC 4-Blade Whoop Propeller (Set of 8)

These Gemfan 40mm 1636 four-blade propellers are built for 75mm-class micro whoops, with a steep pitch that rewards higher-KV motors with sharp acceleration and strong cornering grip. The 4-blade layout adds low-end thrust and smoother throttle response than a 2-blade or 3-blade whoop prop.

Key features

• 40mm (1.6-inch) diameter with a 3.6-inch pitch for punchy, responsive throttle feel
• Matched to 1103–1105 class brushless motors rather than lower-KV micro stators
• Moulded from shatter-resistant polycarbonate to survive repeated indoor impacts
• Friction-fit 1mm centre hole presses directly onto the motor shaft, no screw needed
• Available in Clear Yellow, Clear Red and Clear Blue
