Ron, the KR2 is significantly slower than the (still) published 180 mph. And I believe that early claim was for top speed, not cruise. Almost no KR's have retract gear anymore (and haven't for many years --- bad original design), and even with the later larger-bore VW engines, cruise is in the 140-150 mph range. Top speed 165-170. The few flyers who have put a Corvair engine in their KR are getting up in that 180-195 area. And loving it!
