You have made some excellent decisions. Either one work very well indeed and both will provide more that needed power without excessive weight. The better than average throttling of these engines is where they really shine and the reason having more power than needed is not a problem .

Just so you will know let me give you a little history about the AX line. The original .46AX was introduced I think around maybe seven years ago it was intended as a replacement for the .46FX. The FX's most all of them were formerly my favorites and I loved them I think having around 16 25FX that I used especially for my multi engine airplanes.

The 46FX I beleve experianced a bad production run and experianced cylinder peeling some years back and I beleve it was only one batch but that stigma may have promted OS to an early introduction to the new AX line and specifically the original .46AX. This AX While a fine engine in it own right ended up being an orphan an unlike all the rest of the later AX's with a vastly different carburator and setup that has been used on all the subsiquient AX's and while I do not consider myself an engine man I do feel this is one of the key points that made the AX's so special.

The 46AX11 or series 11 is now is an AX inside out and and just like the rest of the series, Its a great choice.
