The issue of stability has been a major topic of discussion since the KR debuted. This issue is something that is becoming a thing of the past. If you install the new AS504x airfoil and use the matching tail feather templates with the new recommended incidences, you too can have a stable flying KR. The proof is in the pudding. There is a new flight photo on the cover of my web page which I took this past Saturday morning from 5,000', while in a hands off level, right bank of my airport. Here is the link: http://mywebpage.netscape.com/n886mj/homepage.html Photos like this would be hard to accomplish in a stock KR with the original airfoils.
