Default RE: Interest in build photos

Thanks Jim. Yeah, I'm still debating what to do about the CG. The plans show it at 39-40% back. But I took out the incidence in the stab, setting it to zero and reduced the wing incidence to about 1 1/2+ degrees. So I'm losing a bit of the lift that the stab would generate if built per the plans. I looked at the instructions in the online manual for the new ARF that Goldberg has and it indicates a 25% CG. I do tend to build very light since FF is really where most of my experience lies, and many of those planes balance at 75 to 80% back with true lifting stabs. As it is, I can go from 25 to 40% just by moving the battery pack.

I think what I'll do is take it up for the first time at around 1/3 back and see how the elevator feels. I'd rather have it be a bit over-stable/sluggish since it will be my first flight in over 12 years. I think I'm a bit nervous!
