Simple wing hold down

[Ed Miller]

Bolt on top of wing is just plain ugly.
Actually what I don't like about retaining the wing with small bolts at end
of wing tube is you need to elongate the hole in the hard point of at least
one wing to allow for some wing panel adjustment independent of the other
panel. I still cringe at drilling holes in a CF wing tube even if it is
backed with wood/pvc/nylon or material of the week. I'll stick with hooks
with "O" rings or Hanson's wing retention method in the fuse. For the
engineering types, without the weight of hardware/hardpoint a foot or so
from centerline of fuse, a plane should stop rolling faster.
Can we measure the difference ???  : )

Yo, Anthony ...
That idea makes so much sense, that it hurts!
As the old addage goes, "If you can't hide it, scream it".
Put some sort of trim around it: make it look like a gas-cap,
after all, it's in about the right spot.

Dean P.

The last four planes have all relied on the $4000 bolt. The latest has a
great innovation. The bolts are on the top of the wing. I always complained
it is aesthetically unpleasing but pretty simple. Leave the tube in one
panel and the plane comes out of the car to have the wings installed
immediately. Plane gets carried in one piece to pits to be fuelled. One bolt
and I am ready to go fly. If I get nervous and need to check it is right
there in plain sight. Very quick when it rains too!
