Can anyone tell me their CoG? Mine seems a long way back and although it flies (and glides) well enough it just bugs me how far back it is.
The manuel quotes between 48-52mm from the leading edge.
Mine is 51 and It fly's great.
The spar is a little tricky because the wing has a bend in the middle and also another at the servo cut outs.
