No limits...
I don't think so.
Also, the props I listed have the D-1 hub, and are designed to withstand the high RPMs this engine will deliver. Most Sport props are not really designed for these RPMs and may fail.
After Break in, I would prop the engine to peak a minimum of 19,000 Rpm and not any higher than 19,500. Change props until you are within that range, run the engine 300-500 rpm richer (300 with the smaller pitches, and 500 with the higher pitches) than peak, and you should be good.
I normally break my Q500 nelsons in with a 8 3/4" x 8.5 W prop at just over 20,000 rpm.
