I have a P1 that has a Walkera G3D gimbal and Multistar 4000 ma battery and Gopro camera. I bought a set of DJI 9450 props as I have heard they work better with the extra weight . They did. I had a tip over one day in my gravel drive chipping the props. I ordered same props from same seller and came in same package. I was just getting ready to fly and as I was checking props, I noticed 2 are DJI and 2 are the xoxo props. That's crap. That's not what I ordered. You really have to look close to see the raised lettering on the props. They were the same price both times. I haven't had any problems flying but this bugs me. I only buy OEM props....so I thought. Always take a good look at what you get.
