APC 4.1x4.1 prop constants
hi, I canīt find the prop constants for the APC 4.1x4.1 , want to see how a motor will behave with it using the following tool.
I saw that even in the peakeff graphs the thrust for this prop is not calculated. Can someone explain me why?

I just calculated from test stand data with a Grayson SuperSonic V2 motor and a 4.1x4.1 APC E, using Motocalc: Power Constant = 1.60, Thrust Constant = 1.053
That is not at all close to your estimates - why are we so far apart with the Power Constant especially? If I understand it correctly you have Kp = 1.0, Kt = 1.12
