So you would recommend the 10x4 on an OS .40 FSR as well?
Yes. If you feel it is winding up too much (RPMs too high) with a 10x4, switch to an 11x4.

Looking at Demon's picture, I don't have sufficient "up" in my elevators at rest. Perhaps its very sensitive.
The elevon angle is very critical. If your's doesn't match the diagram, I highly recommend that you adjust it so it does.

Perhaps I just need to chuck it harder.
Perhaps. With the plane set up as recommended here in this thread, it should glide about 20' on a mild toss without the engine running at all.

It turns fastest with the 9x6 MAS. This was the prop recommended by Fox (or a 10x5). Should I go back and try the 9x4 MAS again??
I would. Since the 9x6 has a steeper pitch than the 9x4, the 9x6 WILL turn slower RPMs. If the 9x4 ran at slower RPMs, something else was wrong at the time.
HTH,
