Netters, For you relatively new KR fans: Still on the web is Bill Reents's KR-1 along with his many adventures and pictures of his and many other KR-1 projects. The home page has a picture of his plane in inverted flight.

The KR does great aileron rolls. I have also paused for a few seconds inverted and there were no adverse flight habits. I wouldn't fly extended inverted as the airfoil is not symetrical and doesn't fly inverted all that well.
