Compatibility & Build Notes
Build note 01
Best suited to 4-inch builds that are tuned around this prop diameter.
Build note 02
2-blade geometry with a 1.9 pitch usually trades extra grip for higher load on the motor.
Build note 03
One retail pack covers 4 props, so confirm whether you need one full quad set or spares as well.
