    Nitro Models 50cc Ultimate CG????

    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.[&:]

    RE: Nitro Models 50cc Ultimate CG????

    i just flew mine this morning, I set my CG @ 15-16CM. it is nose heavy. I am goin to take some weight out. right now my CG was set about 50% of the chord and it was nose havy, Im thinking I am gonna try about 60-65% chord and lose some nose weight, right now I had to put about 2 pounds up front. It flies great but was way to noseheavy upright. But I sheared the right stab off in flight. got it down. now I need to fix it. but my CG was @ 5 3/4" measured from tip of top wing back
