Wing twist, slightly off topic

[Bob Kane]

Although I have not checked the lateral balance, once
trimmed for level upright flight, the plane maintains
wings-level inverted flight without re-trimming. 

Also, while it is a two-piece wing, the two halves
butt together at the root and the whole affair bolts
onto the bottom of the fuse as a single piece wing
would.
