Surface temperatures varied from 105 (Death Valley) to -20 (approaching
Mach 1 near Amarillo)
Seriously, probably no worse than a typical DF is exposed to during a 3 day
flight.
We avoided warping the wing by supporting it at 2 points with huge batts of
foam rubber and then strapping the wing down into the stuff. That left the
middle free and unstressed. I attached a "Jesus rope" at the very front of
the wing, tied down to the bumper to serve as an "Angle of Attack
Guarantor", but didn't tighten it which would have stressed the wing. (If
you don't know what a Jesus Rope is, ask a helicopter mechanic about the
Jesus Nut at the top of the rotor.)
Where the rope or straps came over the trailing edges, Nate cut some pieces
of aluminum and folded them over the edge as added protection against damage.
The proof of the pudding is in the eating, and the wing came out unscathed,
so I can recommend this as a technique if you need to move a wing and don't
have a trailer.
