Gemfan 1636-4 40mm 4-Blade Whoop Propeller (Set of 8) – 1.5mm Shaft – T-Mount

Build note 01

Best suited to 1.6-inch builds that are tuned around this prop diameter.

Build note 02

4-blade geometry with a 3.6 pitch usually trades extra grip for higher load on the motor.

Build note 03

Check for a 1.5 mm shaft or hub fit before checkout so the pack lands on the right motor setup.

Build note 04

One retail pack covers 8 props, so confirm whether you need one full quad set or spares as well.
