Jim Hill stretched his KR2 into a KR2S, but he had a pretty good reason...he broke the tail off the plane in an engine out landing here at M38, and had to fix it anyway. I don't know of any pictures though. The end result was almost un-noticeable. All he did was clean up the ends of the longerons into matching tapers, scarf on some more plywood, stretch the elevator cables, and blend it all in with body work. The aft deck transition had to be blended as well. He also installed the "new tail", but it's easy enough to simply extend the current horizontal stab and elevators with carbon fiber (as done by Troy Petteway). That alone improved the KR2 stability considerably, according to Troy.
A KR2 can be lengthened, but increasing horizontal stab size will accomplish almost the same goal with respect to longitudinal stability, and is a lot easier to accomplish, as Larry said. Mark Langford, Huntsville, AL mail: N56ML "at" hiwaay.net website: www.N56ML.com
