I ordered a new set of props as spares for my P2V+ that's not a V3.0, don't know if mines a V1 or V2. I didn't know they used different props. The old prop is part #9443 and the new for the V3.0 is part #9450. The new prop has more pitch and said to be more efficient. The V3.0 uses different motors also. Any reason not to use the #9450 props on mine, don't want to harm the motors?
