Peter and Brett,
You can check out Sonex883.com for info on a Rotax powered Sonex.
It will require translation to English, but they have some performance data and their contact information.
At economy cruise they claim 110 kts but this is at 4500 rpm where 5500 is max continuous. They also claim climb of 1000 to 2000 fpm.
There are multiple YouTube videos of Rotax powered Sonex Aircraft in South America and Europe, but not many with performance figures. I am assuming the Rotax 912 ULS will at least have the performance of an RV12 with a Rotax and probably do a lot better.
I have the Rotax engine mount and mounting bars from Sonex and will be purchasing the engine in the coming months.
