bridging the RC/ultralight gap

20 lb, 23hp 400cc 5 clyinder radial.

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)

I have recently heard about a scale B17 project (I thought it was 1/3
though)

Would it work on this plane? ...it's a twin.

I believe the Cri-Cri flew with 2 8 HP chainsaw engines.

I'd prefer a B-36. You could even bolt on 4 R/C turbines if 6 recips are
not enough.

Imagine the stir it would cause at a fly-in...

So.....why do you have to mix the oil and gas for this "4-cycle"
engine?

Excelent question...
Maybe there is no oil bath/sump (like other common 4 stroke RC engines)

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....
