I got from the guys at the german "Warbirdforum" this very, very helpful tool:
FLZ-VORTEX
With this help I was able to calkulate the CG exactly.

The next few steps I moved the akkus and the servos as far back as possible.





With this, I don`t need any lead
A friend lend me these cool scales.




The weight is okay, the surface load is close to 100 g/dmē.
The CG moves only a few millimeters when I retract the landing gear.


I`m also very satified with the balance around the longitudinal axis


So, now I come to an end with this building report. If the weather permits I`ll give you some final pics and,of course, a video from the maidenflight. That will be more in the next year than in the next few days. One of my friends said: "You need good weather and courage.
Five years fun to build.

Thank you all for your followship and helpful motivation,
all the best,
Thomas
