KISTEX,

Did you have any idea where the CG should be instead? I'm a little confused, especially after that I have seen that I have to add about 500 g ballast in the tail. Engine is a OS 120 Surpass II.
To all the guys who has this thing in the air: What did you think? Is the CG correct? Mine is "grounded" so long[>:]. No maiden flight before I have figured this out.
