They are more likely to spin off when the ESC brakes, thus the switch to the composite hub. They'll fit, but fly at your own risk.Are we sure the P2 Vision+ V3 props are not compatible with the P3? I have not flow with them, but my P3 arrived today and the new and old props are the same size, have the same 9450 model number and the P2V+ v3 props seem to tighten just fine onto the P3. ...Not that I would fly with them if no one else has...
