I need to know the size (length and chord) of the UAV spreading wings s900 propeller. It should be 1552/1552R and the only info I was able to find was this size: 15×5.2inch (see here). I found that the 15 inches is diameter, so the length is half of that. However, 5.2 is a pitch, and I cannot understand how do I get chord size from that.
P.S. I don't own the drone. I only need to know the size, so I can't measure it myself.
