I don't believe there are any, at least, I have never seen one and have been to a lot of KR Gatherings over the years. Also never heard of any like that being completed, on the KR Net. Maybe that says something about the building time or difficulty, who knows.
See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2011 - KR Gathering in Mt. Vernon, Il - MVN There is a time for building and it never seems to end. Daniel R. Heath - Lexington, SC -----Original Message----- I'd be grateful if others who have built this way could chime in and let me know how well this has worked for you. I'd also be interested in seeing photos of flying KR's with 90 degree corners.
