" a MA will register higher revs compared to an APC of the same size"
The other day I tested back to back a Master Airscrew 11X6 black to an APC 11X5 (cause that is what I had) and the MA went 13,500 while the APC went 13,200 despite the lower pitch.
I crunched the numbers, and they agree if I keep the prop constant the same, but correct for pitch.
That shows that the MA has less effective pitch than the APC.
MA will pull very slightly harder, but APC will fly a lot faster.
