I constructed fairings, affixed to fuselage, with foam and BID. Rigging
is not impossible, but admittedly the arrangement is not for frequent
rigging/derigging. I use an adjustable dolly on casters, which if
adjusted correctly means that once the wing root enters the lips of the
fairing, alignment of the pins is automatic and it just slides into place.
I used 3 layers of cloth (2 outside, one inside), which seems to have
the proper flexibility in the lips of the fairing. I also had to remove
the guides, since due to geometry on the way in they no longer worked
right. An advantage is the ability to do a correct fairing back in the
area of the flap, to minimize interference drag in addition to better
aesthetics back there also.
