Status: offline 		If there is a gap ( about 1/8" between the wing root and the fuselage of a 60" wingspan airplane , how would this effect the flying qualities?

Status: offline 		ZPAT, I am not completely sure but I do know that the fuselage usually maintains airflow over the wing as the air has nowhere to go but up and over. now on the other end, the tip, the airflow is to a degree lost as it slips over the tip and does not maintain laminar airflow. This is sometimes fixed by adding wing tip caps or on full scale such as the C-17 or some of the newer airliners you will see the wingtip curves upward almost like a vertical stab but much smaller. Wings are designed by people with much bigger heads than I and I would be very careful about changing the properties of them, remember your wing is thickest at its root thereby creating the most lift. Your plane will probably still fly but I would definately do what I could to close that gap, also if it is only one wing that has the gap you will most likely have one wing longer than the other which will also cause some sort of adverse affect, probably a rolling moment which can be fixed with trim I would think. Wish I had a bigger head to help you with,good luck.

Did you build this plane? Next time take it easy with the sandpaper.
