Thousands of thanks for this answer and your suggestions about placing the CG point!
I'm going to mount the throttle servo tonight, since the former owner had a much smaller servo for throttle operations and had modified the servo position by adding some thin sheet of wood over the ordinary hole made for it.
I look forward to getting up in the air, and I am going to train hard this summer to learn aerobatic flight..."aresti.
Hope not to break my plane the first thing I do...
Just love it..! Thanks again for the answer, it helps a lot! /Regards, Jozzi in Sweden
