Adjusting the square 5/8" x 0.035 tubing takes about 2 hours. Next the diagonal longeron at the cockpit area that hold the undercarriage attachment was formed. However, the longeron which attached to the horizontal back spar has misaligned and need to re do. Problem caused by over filing the vertical tubing side. Future, to start filing the horizontal side of the tubing with tail rat file and than adjust fitting by slowly filing the vertical tubing side.
