Iím just curious about why. It seems like any drag reduction for finishing off the flap, aileron, etc ends would end up maybe increasing drag. The only air blowing through those gaps during straight and level cruise, would be the air that is leaking from the high pressure area below the wing/control surface, to the low pressure area above (or below in the case of the HS/elevator counter weight area). Wouldnít you want to limit that leakage by leaving the ends open thereby increasing drag in that small area? Iím probably wrong about this, but it seems like you would be dumping generated lift and thereby increasing drag by requiring a corresponding increase in AOA and induced drag to make up for this lift leakage. Granted, the difference would be minuscule, but so would any perceived aerodynamic drag reduction from finishing an open rib end (absent any loss of lift). Maybe I donít understand the aerodynamic airflow at the trailing edge of a wing, but Iím curious if youíll see a difference using this technique, and what that will be.
It looks nice though, and if thatís the goal, I think you did a nice job of it.
