Bill, I will definitely try the line method, this seems more accurate than what I was doing. I have a big Dry erase I will board I build on so I think that will work perfectly. To clarify further, what you're saying is that If I'm targeting a CG that is 4.5" back from LE (near fuselage), I should not be concerned with the fact that at the point where the landing gear are, the CG is no longer at 4.5" back? Just measure near fuselage? The Line method seems like it will make this easy to measure thats for sure. I will try again tonight and see if that makes a difference.
I realize that in comparing the GP Balancer to the Xicoy cg points, they would differ, but I didn't expect them to be so far off. A couple MM perhaps, or 1/4 oz or so here or there, but they were way off. But alas it could be how I was doing it. Thanks for your reply and I'll try it again tonight.
Tom...
