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.

Ref: Propeller Basics

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

I just tried to measure mine because I want to try a 3 blade propeller. I don't think it's 1.7mm and I'm surprised you got such a low "thickness"... It looks like 3-4mm to me
