Probably everyone else knows this, but on a museum tour last week at Edmonton City Center Airport I noticed a restored Fairchild 71C. These aircraft were used extensively in northern bush operations in the 1930`s. The feature that caught my attention was the "wing folding" assembly that matches the Kitfox/Avid design almost identically. The front spar pin on the 71C is horizontal as opposed to vertical in our a/c`s.
And here I thought we had something unique. The design pioneers were 50 years ahead!!! I just posted 3 pics in my albums for those who may be interested in this snippet of history.
