I have 8 new 9450 props from my P2V+ never used and wondering if anyone has used them on their P3A or P3P? The only difference I can see is the P3A props that came with the bird (purchased a few days ago from Henry's Camera) have a plastic threaded inner and the ones from the P2V+ all have what appears to be metal threaded inners. I attached the P2V+ props to the P3A and they seem to fit fine and tighten right down. My understanding of the number stamped on the prop is that the 1st two numbers (94xx) refers to the overall length of the blade (tip to tip) ie. 9.4" and the last two numbers (xx50) refers to the pitch of 5.0". So the props are identical except for the metal vs. the plastic inner threaded part at the "hub" . Also note: it looks like I do not have the very latest upgraded motors but they are the more powerful ones.
