I acquired a GSP extra from my brother, who got it from another guy. The instruction manual is long gone, and i have no clue where the CG is supposed to be.
Should it be on the wing tube or slightly forward of it?

Thanks in advance for all help

If its the CMP one, then the CG is 115-125mm from the leading edge at 200mm out from the wing/fuselage join.

Hope this helps
