I understand that there is a danger of getting water inside the wings if
they are left outside in the rain on a trailer, aileron edge up as water
collects in the 'gutter' formed by the aileron closeout and enters the wings
through the pressure relief holes.
I was considering making a couple of canvas 'envelopes', just over the
length and depth of the ailerons, open at the lower edge and inboard end to
slip over when the wings were on the trailer. I would hold them in place
with a couple of bungees down to the trailer. This would also stop the
ailerons flapping about in the wind when trailing although I haven't seen
this happen yet.
Anyone got any better solutions?

Richard,
Although it won't help with the water issue, a lot of sailplane guys who use
open trailers have made simple aileron locks. It's just two pieces of 1/4"
ply about 3" square with a piece of carpet glued to one side of each each.
Drill a small hole in the center of each piece after the carpet is glued on
and insert a short piece of 1/8" bungee cord or string and tie a knot on the
opposite side of the ply from the carpet. The carpet acts as a pad where the
lock touches either side of the wing tip and aileron. The length of the
string is determined by the thickness of the aileron. The string or bungee is
simply slid into the slot between the tip and the outboard end of the aileron
to a snug fit. Sandwiching the aileron between the two pieces of carpet
covered ply the aileron is "locked" in place and won't move. Simple and works
very well. Don't forget to take them off before you fly though!

No better solution that I know of.
Just to emphasise this is a very real problem. The water gets in the wing
and ends up in the leading edge. From here it is difficult to get it out.
On Karl Heindl's XS (#392 C-FIRS) we tried all sorts of tricks to get it
out. Eventually we had to stand the wing vertically (tip up) and remove the
front lift pin. This produced at least two gallons of water.
It is quite easy not to notice a 20lb weight change in a wing as you
normally never lift the full weight but are manoeuvring it from one end.
The last thing I personally want is to find one wing 20lbs heavy as you
start to rotate.

Alan,
Two plates go on the double rib - one each side - the inner one on the inner
side, and the outer one on the outer side. There's recesses moulded in the
rib for them. The exact separation of the ribs (they're on flox beds) is
ensured by the W21's you put between them when laying up.
One plate goes on the intermediate rib as shown in the manual. It goes on
the side that does not have a flange running onto the lower skin (so on one
wing it is on the inner side, on the other it is on the outer side - this
bit is crystal clear as soon as you look at the wings, much easier than
explaining).
Set the plates for the double rib first as instructed in the manual, butting
up to the closeout. Then sight along the lower skin to align the middle
plate exactly in line from the root plate to the double-rib plates. You may
find the double rib is not perpendicular to the spar, hence the plates there
appear fractionally shorter when you sight down the wing - just make the
offset fore and aft equal.
In practice I found I had loads of room for manoeuvre when I fitted my flaps
- having set the plates to about a half-millimetre accuracy. In reality on
my wings and flaps I had quite a few mm to play with. After worrying away
about the flap-fitting exercise for some time, it turned out to be very
straightforward. In fact I'm not entirely happy with the positioning on one
flap and reckon I can do a better job (I was tired, it was late, usual
story), but redoing it will simply be a case of using a new set of
W19/W20/W21s and drilling through my existing holes in the W18s.
The W18s are quite a fun layup to do - much nicer than the rib
reinforcements at the root - enjoy!
Regards,
Jeremy

Alan,
The W18 plate on the root rib is already in place, at least it was on mine.
I don't know if there are different versions. There are two W18 plates in
the
outer location.What you may be looking at for
to two outer plates in the drawing on page 8-14 is the plywood spacer that
is bonded in place after the epoxy on the W18 plates cure. The W18 plates
do indeed go as the manual states, the joggles help with location. Also
look
at Fig 6 on page 8-4.
John, A230

For those contemplating building or obtaining a trailer, I think this recent
thread highlights just one of the advantages of a closed in trailer.
As well as providing protection from water ingress, a good closed in trailer
also provides protection from :-
(a) Sun as well as rain
(b) Stone damage from passing vehicles
(c) Dust ingress
(d) More protection in the event of a vehicular accident
(e) Considerable roll over protection
(f) Wind gusts from passing trucks
(g) Hail damage
(h) Better security (if lockable)
In my case, it will also be used as the permanent storage location for the
aircraft.
They also make excellent furniture removal vans!

Thanks to all who answered my questions.........it is now clear what the instructions
are saying. I more fully understand what a "joggle" is now and see the
right places for the plates.

And one more for the list:
(i) That dreaded winter Road-salt (for those who live in northern
climbs)
Because of the salt, open is just not an option for me.
