Hate to open this can of worms but here goes.
I have the PropPowerCalculator that has all the bells and whistles now. I notice the "Corrected Prop Constant" is different for different propellers and this makes perfect sense to me, but I notice the Master Airscrew black prop has a value of 1 while the Schimitar has a value of .95 and the APC 1.2.
It appears to me the schimitar just by it's shape would fall somewhere in between the APC and Master Airscrew black. Is the Schimitar a poor design? []
As always I appreciate your enlightenment.
