The plane was given to me by someone who flies an identical one in my club. It's a foamy built from plans. I believe they got the plans out of the Model Aviation Magazine. All the plans say about balancing is to measure 2 inches back from the leading edge and balance it at that point near the center.

The guy who built it confirmed that is indeed the CG. His plane flies great. By great, I mean absolutely perfect. Beautiful. Coasts at near idle or roars at full throttle and does any trick imaginable. I'm not sure why he didn't have to add so much weight and I did; I guess he has a heavier motor or something.
