The 10x6 or equivalent load is the "Normal" prop for the average 0.46, but many, including the XLS 46 Magnum will run fine with a 10x8 equivalent load.

Don't be scared by the term "Equivalent Load," that just means if you need a larger diameter you decrease the pitch, or a smaller diameter increase the pitch.

On one of my twins, with a pair of Mag 46 engines I'm running 10x6 three blade props, my Modeltech "Magic," with a 46 FX has a 12.25x3.75 APC. A 12x4 would be about the same load. Or a 9x8 prop.

Generally, on a sport plane, start with a 10x6 and see how it goes, adjust from there.
