Found it on the Vanguard website, for their Japanese built engines

Strip off the massive air cleaner and any ugly steel parts, shave a few kilos off the flywheel (a mate in Brazil is already doing just this to his) and specify the 4750rpm version.

Hitch that to my Ace Aviation redrive (designed for 40-50hp) and that would fly forever.

Wonder if it could get up to two seater power?

Heavy, but can be shaved down with care

How about 40 hp in only 10Kg?
or even 120 hp in 28Kg

Ray,

Good idea, but Wankels are expensive and thirsty I believe.

Best regards,

Twenty five to thirty litres an hour thirsty. Wish the Briggs were around the weight of a 447!
