Can anyone tell (or show with a picture) me exactly where the CG point is for setting up the FT Sportster? I'm having some issues with it being tail heavy. The build video and plans dont really show where it is on the wing. All it takes, when checking the cg with the plane upside down, is a few fractions of an inch to completely change the cg when putting my fingers on the recomended 2 inch from the leading edge area. I already added 14 grams of weight to the nose and it still seems tail heavy when checking cg. If I move my fingers just 1/8" towards the tail, then it balances out ok.
I built this one a little on the heavy side, almost 1,000grams AUP and the tail has some extra weight from reinforcement and a plastic tail skid. It has unbelivable power from my upgraded power pack, but I'm not sure the design like all the weight...
