They must have really made a gutless design with the AX.
No... not at all. The .46-Ax is an EXCELLENT running engine with tons of power. I was just looking through the manual and 12x6-7 is actually one of the recommended props. I did not realize that. Still, my experience tells me that APC 11x5 or 11x6 is really, really good for most sport flying.
