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?
