At some stage you'll need to replace those chipped and dented props on your Phantom 3 or 2.
These are the latest version DJI 9450 replacements. Each pack contains 1 clockwise and 1 counter-clockwise propellor.
They're self-tightening and compatible with both Phantom 3 Professional or Advanced, and backwards-compatible with Phantom 2 or Vision+.
Durable plastic construction provides both lightness and rigidity. Each propellor weighs just 13g.
NOTE: On a Phantom 2, never mix & match these props with the older 9443 props. All 4 props on your Phantom need to be either one type or the other. Newer 9450 props will be far more efficient.
