Hi!
First of all forget about what rpm you get! It isn't rpm that is meaning full, it's what prop that works best in the air that counts!
APC is superior to MA at least when you compare MA white-blade -tiped -props, but that doesn't mean APC is superior to all other brands.
Graupner "Cam-prop" series or Graupners still newer G-Sonic props (resemble APC) are good too, as are the British RAM series of props.
MA Scimitar series are rather good too! But avoid the MA white tipped props, noisy and no good performancevice!
