Hi Stef, I was looking into putting a BMW R1100 motor on my KR-2 project. I asked this same question on the net a while back. All I could find is "maybe" some guy in New Orleans, LA has a BMW on his KR aircraft. I was not able to get a hold of this person. I was realistically thinking about it and the R1100 motor is lighter than other airplane engines and the KR aircraft need to be a little more nose heavy to fly good. A heavier engine would maybe make your KR fly better. Another issue that came to mind about the BMW engine is that gearbox, it is just another thing to break, where an O-200 would just be a direct drive. I believe the engine itself could handle being on an airplane, that's how BMW got started. Here are some links that might be helpful.

Steve glover is bussy for me to try to get an approval, but if there is someone who is flying this setup. It is much much eesear. I Dont have any problems with my certification. In the Netherlands it is allowed "" if there is already an aircraft certified flying with the KR, you get a certification"" Let me Know.
