gaining 1000 rpm?
 
Probably not going to gain a 1000 rpm from prop work right? I tried a set of ROLLA props that get me on plane like a bass boat and carry the boat great but can`t get much rpm out of them even thou they are 3 pitch sizes smaller than my current 6000rpm props .

the cup must be thru the roof they don`t slip at all.

I would map out the blade area of each 'ear' and compare to your previous set of props. I have templates of all my prop ears as surface area plays a big factor in RPM control, just as much as pitch. A Rev4 is probably the best example of this. A Rev4 will typically load the motor the same as a 3 blade prop that is 2-4" higher in pitch. For example a 19" Rev4 loads my motor nearly the same as a Mirage 23" and more than a Laser II 21". YMMV.

sounds like youve found the perfect prop, another 1000 rpm is easy, just change blower pulleys till ya get there.
