I'm trying to come up with a conversion for RPM to power. I found a nifty equation, but I need the blade pitch. Such is measured as the ratio of the "height" of the blade v. its chord at the 75% radius position.
The chord is 14.87 mm at that point.
Can somebody measure the height? I get 1.7mm if I use the method on the site. (actually used a calliper with a thin metal plate and subtracted the thickness of the plate).
Can someone confirm this "thickness"?
Pitch comes to 8.75 using my numbers.
See the article below.

That said, I'm not convinced the equation there will work well for a quad as for a propeller in forward stable flight.
