Note that in Bob's rig, the track of the one man dolly is MUCH greater than
those that must clear the tailboom/rudder. This makes it very hard for the
wind to overturn it. Also note that Bob rotates the wing level almost as
soon as the root is released from the root dolly. I've seen Bob de-rig his
very heavy LS3 in a 40 kt wind.

I think this system is WAY safer than the "do-si-do" of walking the wing out
past the tail especially in a high wind.

What helps a lot with the Udo rig is to have an assistant hold some
portion of the dolly while I do all the maneuvering. This person can
then provide whatever stabilization is necessary to keep it form
tipping over.

Never let someone help at the tip for two main reasons:
1) They will want to help by lifting, thus making the root end
heavier!
2) If the rig starts to tip it is very hard for the helper to realize
it's not the wingroot person making the move. I've dropped a wing due
to this method

I have also found the dolly itself is much more stable and the wing
doesn't slide around if the leading edge is kept down while
maneuvering. Of course, this means that a helper is mandatory if
there is any wind. I use the rig primarily to protect my back from
heavy lifting (ASH-26E wings are quite heavy) and to allow a more
leisurely and relaxed assembly that lets me pause to deal with any
glitches that come up during the assembly.
