I need to do tests into the drag properties of propeller blades later. Get an idea into how much drag they produce depending on pitch.
I'll forget otherwise so I'm putting this up so one of you blokes can remind me.
Thank you.

@MIGFOXHOUND31BSM26 Yeah I have time now I think

@Boeing727200F I was busy :(
i can do it right now!
sure
@StockPlanesRemastered Hm.
Try giving a propeller a massive cord (dozens of meters, at least), and align the blade with a rotator above it.
Set the pitch control to be controlled by VTOL (or throttle), set a text block to output the VTOL/Throttle as a number. Should be more precise in the case of throttle.
Since the chord is enormous it should be more precise and easier to match the rotator angle to.
Connect the rotator to trim and connect trim to a similar text block as to VTOL. Rotator should have a very long beam connected.
Load, set VTOL to 100%. Align the rotator's beam to the leading edge of the propeller blade.
Compare max rotator angle to the percent trim and work out the angle. Unless Rotators have an angle variable output, in which case disregard trim and just use that.
That should give the angle for pitch.
In an excessively complicated format, I'm sure.
What would really be useful is a calculator that tells how pitch percent equates to degrees of pitch.

@MIGFOXHOUND31BSM26 Couple hours.
How later?
Sure mate.
