Working on getting the trailing edge of my wingtip to match my aileron. I split the end of the wingtip and the outer edge up about 4 inches. Heated the top surface and was able to get the top to match the aileron. However I could not get the lower portion of the wingtip to move enough so it pulls on the upper surface (edge) and the gap is still about ½ inch between the aileron and trailing edge tip. Should I consider cutting the lower part of the wing, making a new form to get everything to match my aileron? Suggestions please.
