I see this thread hasn't been active for about 6 years now. I hope someone can still answer my question...

I bought the Big Bee ARF from Tower probably 10 years ago. It arrived with lots of damage. The ribs in the center part of the wing were all broken and had to be reassembled like a jig saw puzzle. Thank goodness all the pieces were there. The bulkheads in the fuselage (under the wing saddle) were all broken and had to be reinforced. I'd given up on this airplane and it languished under my work bench for 10 years.

About a month ago, I repaired all the damaged pieces and assemble the whole airplane. I flew it for the first time today and was a bit disappointed. Apparently the CG location in the instructions is way off. The instructions say the CG should be between 5 1/2" to 6" from the leading edge. I balanced mine at 5 3/4" and it was way nose heavy. Even with full up trim I had to maintain back pressure on the stick to keep it from diving at the ground. I was able to land it without damage, but now I'm puzzled.

Does anyone know what the actual CG location is supposed to be?

P.S. I'm using a Magnum 52 four stroke for power and it had plenty of power to get it off the ground and keep it in the air even with the plane being so badly out of balance.
