Has anyone else had experience with the P3 props? Target had them on sale for $6 this weekend, so I splurged and bought a set to try. Seem to be completely compatible (except for the color codes, which doesn't affect flying). They seem to fly just fine and the price was certainly right. I was amazed the local store had them in stock. The package was labeled Phantom 3, Spare Part NO. 9, UPC 90021 0008.
Yes, P2 and P3 props should work with the XSP. I bought some aftermarket Aeronaut carbon fiber props from Carolina Dronz (sponsors of this forum) and they are advertised to work on all 3 drones.
The Aeronauts seem slightly less noisy and seem a bit peppier, but I'm not sure they justify the extra $30.
