How do I attach the wheels and landing gear on a Guillow balsa Spitfire model. Do I punch a hole in the tissue on the bottom of the wing? And where do the "M1" pieces go? The instructions are not too clear on that. I've got the tissue on the fuselage, the wing, the stabilizer and the rudder, all doped, but all four pieces are separate. I know I need to paint them before I glue them together. But the finishing up has got me stymied! Any help would be appreciated. Thanks.
