Hi! Fred.
You need to take care to allow for wing deflection with your fillet
fairing and can easily finish up with it too tight making it difficult
to assemble the wings and causing fretting on the fuselage sies. Too
loose and you finish up with gaps. Your shapes look good. However take a
look at my "rendition" at   ......http://www.crix.org.uk  
Of course I don't know what contribution to drag reduction it makes but
I believe it saves air run off the flap inboard end with flaps deployed
to a degree and it blocks off the flap actuating tube slot.

If anyone has an XS monowheel sitting on a factory-supplied trailer 
with wings stowed for travel, a yardstick and measuring tape, and a bit 
of spare time, I have a request. Could you please:

1. Establish a waterline at the bottom door sill, extending aft from 
the rear edge of the door about 18 inches.
2. Measure down 10".
3. Record the distance from the side of the fuselage at that point out 
to the surface of the wing.

In the interest of drag reduction, I've been working on a fuselage/wing 
fillet which mates w/ the standard XS wing fairing just forward of the 
spar. Of necessity, a portion of this fillet will be attached to the 
wing, a portion to the flap, and a portion to the fuselage. I am trying 
to establish the location of the joints, and the extent to which the 
portion attached to the fuselage can extend beyond the surface of the 
fuselage without impacting the wing when trailering is the big unknown.

A few pixs below explain the general form this fillet is taking

Your assistance would be much appreciated.
