The Katana X was the culmination of a few different larger wing designs.
 
This one had a few new features on it such as the hotwire cut leading edges, KFm step on the underside of the elevons and a double thickness of foam for the core panels (something forgot to mention on the plan).
 
It needed a bit of lead in the nose to get a nice flight performance. But when I got it right it went very nicely indeed.
 
This wing was really intended to use the “LowPro” pod.
