Where is the CG on the 50cc Ultimate? The manual I have says 105mm from the leading edge, presume upper wing;manual doesn't say, which puts it at the front of the wing tube. With this configuration I will have to add 3.5 lbs in the nose to get it to balance. I've never had to add weight like that to a plane, thats the weight of the DA 50 hanging on the front. I don't install batteries until I start to balance, thats what I use them for. Any help or suggestions or a correct manual would be appreciated.[&:]
