Atkins is selling the parts to build a 1-rotor at http://www.atkinsrotary.com/index.php?pag=14

Atkins is advertising 220lbs without radiators, and has a dyno sheet showing 90hp at 6500rpm.

I'm selling my rotary equipped Dyke Delta, and thinking about maybe a Zenith Zodiac 650B.  It needs 80hp to 100hp.  I'm also considering a Corvair engine, which may give me a little more power and a little less weight for about the same money (I know.  That makes me a heretic), except that I could reuse a lot of the parts off my Delta's installation if I sale the airframe without the engine.

What do you guys (and gals) think?
