Sorry... didn't mean to offend... I didn't notice your location. You certainly speak better English than I do your language.
Nice airplane! Take your time setting it up well, you will enjoy it a lot. A buddy has one and likes it a lot... of course my plane flies better
The DA-100 will treat you very well.
I would go to the Giant Scale forum and look through the very large 2.6m thread. Here is the link:

If I were you I would explain that you don't speak English very well and ask for CG and control throw inputs from others... 92 pages looks like a lot to sort through. I speak perfect English and would not want to read it all.
Good luck!
