So I have taken my time building my new Seagull models Extra 260 ARF kit. I went ahead and outfitted it with a new EVO 1.00. I want to balance it but the directions say that the CG is 7-8CM from the leading edge of the wing, MEASURED from the wing tip. Since this is measured at the wing tip does this mean that I cannot use my CG machine and have to use a helper to balance the model? I am just used to the smaller sized models I use my CG machine on. I also usually balance my low wings inverted. The Extra's manual does not specify if it should be balanced inverted or right side up.
