I haven't run the AX in a plane yet. But based on Randy Cuberly's experience/advice, I think it will be great, at least running in a 2-2-2 with a lower pitch prop like a 12x4 or 13x4.
If it is a mess, then I can always sell it to an RC guy, they are fairly popular.
If it works out, I'll sell the brand new RC carb and muffler, and buy another one.
Might try the smaller AX.35 as well, although I am not sure why the AX.46 is $149, and the AX.35 is $169 (?!).
Must be the new math at OS.
Kind Regards as well,
Target
