I just installed my wings for the first time and have jammed the wings as far as I can jam them without breaking something. I'm still 5/8 an inch out on one wing. My gut is telling me to cut the spar down 5/8 and run with it, however, I'm new to this type of jet and thought better to ask the guys with experiance. This is a brand new spar I bought from Planes Plus, not the spar that came with the plane as I'm second owner, and the spar did not come in the box. Thanks in advance.
