I've just received my new props and I ordered some DJI Phantom 2 Vision props for my FC40 as I was told I'd get better run times. I was thinking I'd need to remove my prop guards but I bought V2 Prop guards anyway. I was told that the Vision 2 props were bigger and wouldnt fit. I think whoever told me that is wrong I just test fitted the new props over the prop guards and they fit just fine visually. They look VERY tight but don't seem to hit. As for sizes I've measured the new props and they are ~9.5" long. The old props are a smidge over 8" long and the prop guards are 10" wide at the very widest points where you tie string to. Does that sound right? I was planning on just taking the guards off as I didn't think they'd fit but as they look like they will fit okay I'm tempted to keep them. Any thoughts?
