Wing fairings --- the last external construction project before final finishing and paint!  Don't ask how I came up with this build sequence...

There seem to be two schools of thought on how to do wing fairings.  One school says to leave a small gap between the fairings and the wing skin, enough to allow flexing of the wings.  The manual suggests this approach.  Another school says to overlap the wing skin a bit with the fairings (say 1/4 inch), leaving enough space around the wing skin to allow flexing of the wings.  A guy helping me has done several IVs this way.  Anyone have views on pros and cons of these approaches?

Thanks,
Dan
