Bernd,

I was fortunate enough to get the design as a package from Philip Kolb. The design is proprietary but I can say that the tail volume coefficient is .43.

That is a good number to start with for a T tail. I would stick with .42-.45. You can make a plane fly with a smaller stab but it may have problems on the launch.

The best reference for design is the Supra plans, both for aero and structure. Also you can take any of the popular J planes and use the fuse/tail proportions as long as you like the handling. The next step would be to use XFLR5 but I am not sure there is a lot to be gained in this area for the effort.

Good luck,

Greg
