John, picked up your Katana 50CC at a local swap meet, but the manual is missing...all I really need is the CG location...I've tried every CG chart and I think I have it about right, but before the maiden I'd like to be sure...I'm at a conservative 5.75" back from the leading edge at the wing root..thanks rlg
