OK now, time to look at the wing attachment. The DHC-1 has two issues here.

First, the landing gear is so damn far away from the plane center-line. The wingspan is a little over 2 meters, but the wheel distance is around 60 cm. If I leave the center wing section, with landing gear, on the fuselage, each detachable wing is only around 75 cm – a rather small wing section. The fuselage is about 1.6 meter long, so a single piece wing of 2.10 m is not really that much longer than the fuse itself.

Secondly, the fuselage is not flat where the wings are attached. It looks like it’s due to the wing incidence. The wing/fuselage is flat at the main spar, but the leading edge is above, and the trailing edge is below the fuselage bottom. The “problem” is clearly visible in the attached photos. I’ll have to think about this problem for a bit.
