Wich motor are you going to put on it? I am interrested by this plane but, all available kits are ARF and as a builder, i would prefer builder mine from a plan or a kit.
In the meantime, here are few Katana's links:

Found a web site with this Katana 3-view a while ago. I´m not sure if it is true to scale
though. The wing looks really thick.
I could e-mail this 3-view as a 40 kbyte hi.res. ps file if you like. When opening it in
Photoshop, the image will be around 6500X2000 pixels or 91X30 inches
