I would go with the .95 AX. In fact, that was my first choice but it was not available at the time I built my plane so I went with the .75 AX. I fly with mfuess and we discovered that the since the .75 AX is so much lighter than the G20, it has no problem keeping up in both top speed and vertical climb. The .95 AX is about the same weight as the .75 AX and has more power, so it would be an ideal choice.
