So, for those of us who know better, what is to be expected lop or ? on a XC at certain DALT? This Paul guy disputes the ability of the rotary to compete with Lyc fuel burns?

Hi Marc!

Glad to hear Dennis is flying happily... but I'd be interested in his fuel specifics. The rotary engines are fuel hogs... with about double the fuel consumption of a Lycoming and LOP... At least, that was Lionel Madore's experience on his twin-rotary (!) 180 homebuilt clone. The CAFÉ literature seems to support that as well... is Dennis experience any different?

Paul,
I think you may have a few misconception on a 'good' rotary engine installation. Lots of 'bad' ones out there, but it works.
