Has flat notches on opposite ends of the shaft hole for direct drop down of DJI motors. (see photo below)
10x stiffer than stock DJI propellers.
A lot less flex during flight resulting in higher efficiency and quicker response.
The 10x4.5 props have a 6mm hole drilled in the front side of the hub, and a 9.5mm hole on the back side of the hub to accept a prop shaft adapter ring.
Also included with the prop is a set of five 9.5mm OD adapter rings that step down the center hole of the prop to allow it fit on 3mm, 4mm, 5mm, 6mm or 8mm motor shafts. If you have a larger threaded shaft on your prop adapter, the center hole can be reamed out to a larger size as needed.
Includes 1 clockwise rotation and 1 counter-clockwise rotation props
