Like yourself, I too just finish the AT6 ARF. This plane was a sweet build. I went with a OS 91 4 Stroke engine on this baby. Did not have to do alot of mod on the cowling to fit the engine. There has been talk about the CG on this bird. The manual say that the CG should be 4-1/4" from the leading edge of the bottom wing. Some people have said that they have lost their bird on the first flight at this CG. The airplane flew tail heavy. Now I set my CG using the Great Planes CG Machine and the CG machine set the CG at 140mm or 5.5" So I mark the spot and found that if I go from the leading edge of the wheel well to the mark, it is 140mm or 5.5". I did mark the manual cg and found the manual cg is 1.5" in front of the manual mark. If you go from the leading edge of the wheel well to the leading edge of the bottom wing, it will come to 1.5" Now my CG is set per the Great Planes CG Machine. Now to have some good weather to test fly her and see what happen. I will report the out come!!!

Merry Xmas to all!!!
