Don; In case you haven't already found it in the archives, I believe Mike Mims (out in L.A.) built his KR with constant-chord "Hershey bar" wings. I don't know if it ever flew, either before or after he sold it. I think he did it to make for simple hot-wired cores.
I got to sit in Mike's airplane when it was under construction, and was impressed with the workmanship and details. Oscar Zuniga San Antonio, TX mailto: taildr...@hotmail.com website at http://www.flysquirrel.net
