PHLIP, that's an easy corner to get into! I've helped myself get out of that corner with 1.5 oz fiberglass cloth and medium CA, to strengthen the trailing edge and tie it to the rest of the wing. With the help of FG & CA, I don't sweat mental lapses anymore, I just let them come . Are you running aileron torque rods the entire length of the trailing edge? The down side of long torque rods is they get twisty and the ailerons will not act positively, they will be springy and too wimpy to deflect much.
