This engine has got to be getting close to bridging the gap between
ultralight and RC (understanding it is expensive for an ultralight)

What could you do with this? twin engine PBY ultralight? (twin because,
reliability?)

the 215 cc verion gets 76 lbs of thrust (that info is not available for
this engine)

Heh. And I thought the ultralight engines were expensive......

Yeah, two of them might power something that you could sit in yourself...

But at 5900 bucks, it's not worth it at all. You could get a Rotax 447
for half that, or a 503 for about 2/3 that - either of those motors you
definitely could power a 'real' airplane with....
