    CG for WM ultimate EP

    Hey guys

    Am finishing off my WM ultmate but am confused by there cg recomendations. In the picture it shows 83mm back from the front of the top wing but in the text it say 83mm back from where the wing meets the fuse. So is it taken from the top or botom wing. This is my first bipe so any suggestions with getting COG right is appreciated.

    Cheers

    RE: CG for WM ultimate EP

    hi i have a seagull ultimate biplane had some fun sorting out cg with her the manual said 10 to 13 cm back from the leading edge i flew like that and it was the scaryest thing i have ever flown second flight moved cg forward to 8 cm was a complete joy to fly my advise is to make her a touch nose heavy first as this is better then tail heavy
