Hi!
The prop to use for general sport flying ...at sea-level...is a 11x6 . Remember the OS LA .46 is no powerhouse in the sense that it like to rew high, but it can turn large props. 12x4 or 12x5 is no problem if it's a slow flying high winged airplane. 10x6 is just way too small for the average sport plane using an OS LA .46.
As for a spinner. Avoid it ! at least a plastic spinner. Use a spinner nut instead!

yeah its a debonair, a spad high wing trainer, the brand is DU-BRO spinner, here is a quesion can my new .46 start with a chicken stick, even though it has never ran before or can a starter start it without a spinner or spinner nut
