Here is where we have been gathering info on this engine since 2010. I have 2 and have been running them on 16x8's and 17x6's exclusively because of the great info in this thread started by jedijody.
In this long thread much has been written about over RPM and engine life. You say you want to put this in another plane someday. If you prop it so on the ground static RPM goes over 8400, the engine will not live long.
You know that we always take the manufactures prop data with a grain of salt.
Go ahead and throw out all the great advice given here. It is your choice.
The MA 15 x 8 three blade has been used with good results.
