    The XR-50 rotary engines have been tried for our planes by Phantom - http://www.phantomaero.com/ Owner had a whole blog on the conversion and trials. Testing memory - he had issues with the main bearing loading to the redrive. These are cart engine - tightly tuned and a completely different loading curve to aircraft.
    New configuration with derated power and more/better bearings might be worth a look. Just because Rotax has reduced their product line doesn't mean the segment of aviation use doesn't have options.
