I've had a close look at that trailer and it's a marvellous piece of
design and construction. The Mini-Nimbus which it houses was for sale a
few years ago and I almost bought it for the trailer alone.

You can see the sealing system in the pictures. The rim of the opening
overlaps the moving panel. I'm not sure how good it would be for
several hours on an unsealed road but there was no sign of water
problems and it was made nearly 30 years ago. I believe there are
rubber seals around the edge but that detail is a little hazy.

When the rear of the trailer is opened, there is a 1/2" square drive in
each top corner on the end of shafts which run the length of the
trailer. Turning these (with a wheel) opens the side panels which have
the wing clamped to them. The mechanism is not just a simple hinge but
works through sprockets and chain. In the second photo, the rear of the
shaft and the rear sprocket and chain can be seen to the left of the
right elbow of the guy in the blue jacket. When you've found it in the
second photo, it's easy to pick up in the first.

Rigging, the fuselage is pulled out and the sides are laid horizontal
with the wings clamped to them. The root holder swings so the tip is
released from its fitting, swung back into position and put on a stand.
Then the root is released and fitted. Altogether a really different
trailer and very well executed.

Built in the bush by a farmer if I recall correctly. The design owes
more to John Deere than Alfred Spindelberger I think.

Mal,

I've thought about a trailer with fold out sides for the wings and
now, I see that someone has made one. See your photo at:

Can you tell us how the ease of rigging and de-rigging compares to a
Cobra or Komet?

How weatherproof is the design? There's a lot of seams that have to
be built "just right" to keep out the rain.
