You should not need to add weight for that problem. You could carefully twist the tail boom to reduce the stabilizer's lean to the right (from the back of the plane) to see if this helps. If it does, moistening the tail boom piece near the motor stick, adding some twist, and pinning it to let it dry that way could help open the circle. BUT, don't try to make too much of a change until you see the results. Otherwise, I'd suggest carefully cutting off the stab and reglue at a lesser angle. The stab, being so far from the cg, has a big influence on how your plane flies. One reason we like to put both stabs and wings on with posts/paper rolls for adjustment.I have a question on my plane. We are flying relatively well, but it seems to be turning in quite a tight circle (about 10 foot diameter). This has been causing quite a bit of problems for us. We are using Ziegler's plane design, thus the tailboom is in a fixed position, making this quite difficult to fix. Do you guys happen to have a solution without adding too much weight?
