Thats to bad Gene, I always hate to see the old trusted stand bys go in especially a plane such as the Kaos. They get some age on the airframe and it doesn't take all that much of a impact to really mess things up. I had a forty size I got used from a fellow and flew the daylights out of it untill one day the engine died in a very bad place, the rest was history, But then you could just buy a new kit , not so now days its all plan build and cut your own. Feel lucky to have such a good friend that had one on hand.
Ya know what they say All planes have a expiration date stamped inside someplace, but i'll be darned if I can find it untill its too late *L*
Good Luck with your new build, Question are you going to do a build thread on it by chance?
