--> Tailwind-List message posted by: "Ross & Shirley Leach" <bacs@powerup.com.au>
G'day All
I am now putting together all my info I have collected on building a W10 TW and
would like any of your thoughts on building metal wings (and any thing else you
may think I should consider). I am comfortable working with alloy and would
like to carry more fuel than the under-dash tank will hold (remember it is a
large country with a lot of nothing in-between some of our waypoints and you
have to carry enough fuel to get home or to a fuel supply. Avgas is had to get
out in the bush here). Could anybody advise me on the pros and cons of the two
wing choices. I am also considering adding 1 foot more of wing per side.
I intend using a Rotax 914 (115hp)or a 3300 (120hp) Jabiru 6 cyl so I can keep
the weight down so as it can be registered with the AUF (Australian Ultralight
Federation). I will be quite happy with 120 knot + cruise. I have flown ultralights
for 15 years and do not want to get involved with GA's and our Governments
CASA with 100 hourly's and the associated expense.
I have a CFM Streak Shadow (860 hours on the clock) I built from a kit which now
has a 2200 Jabiru that I have flown all around the eastern side of Australia
for the last 10 years. Next month in February I will be flying down to Avalon
Airport near Melbourne Victoria to the Avalon Airshow from my home base at Caboolture
just north of Brisbane Queensland. I need a good cross country aircraft
to go further a-field and I feel a TW looks like the answer. A friend of
mine is also wishing to build one with me if I go ahead. There are only a hand
full of TW here in Australia and most of them are W8s'. I was told there is
three W10 under construction in NSW the state below Queensland were I live.
I am lucky enough to have a W8 hangered 2 doors away form me at Caboolture (www.cabaeroclub.org.au)
which I have flown three times and was quite impressed with
its performance with the 0-200 (100hp) in it. Please feel free to check our
web site out. Awaiting you replies.

Ross,
There are people who have built metal wings and even tapered wings for
Tailwinds, but I have never heard any claims that they provided any
advantage over the wooden ones; and complicating the whole project with wing
tanks/plumbing is a double edged sword, to say the least. Years ago SW said
of the Tailwind; "performed a little better than expected". This is
primarily due to the fact that the wing (not laminar flow) is very smooth.
I think smooth wings are easier to obtain with wood than sheet metal,
especially if the sheet metal is thin. Many W-10's have 30+ gallon tanks.
This coupled with the J-3300 should give you 5 hour range at 150-155 knots
for a range of almost 900 statute miles. Time to check the weather and
water the horse by then anyway.
Regards,
Boud Kuenen NX888WT

I agree with most of Boud's comments, but on the flip side, Calbie Wood has plans
for a metal wing with wing tanks. Pretty straight forward, if metal is your
media. I am putting all of my fuel in the wing for safety purposes and to free
up space behind the dash. In order to keep the fuel system simple I'd either
put it all in the wings or all behind the dash. If you are going to use a small
engine there is no need for anymore span than the W10 has.

Hi Ross (and Shirley too),
I am a guy who has actually undertaken construction of a pair of metal
tailwind wings. I have assembled materials, and made some parts, but I have
put the project up for sale (long story - I have another project which I
believed I had sold and the tailwind fuselage came up for sale and the
workmanship was simply too good to pass on). I now have two project with
room for about one-half a single project. That said, I can observe that I
don't think construction of the wings would be a terribly complex project. I
do believe that the metal wings will be heavier and likely measurably slower
as compared with an identical aircraft with wooden wings. Also, I have built
ribs for one wing panel and found it extremely difficult to acceptably
"joggle" the main ribs where they join the main spar. The joggling is
necessary for a wet wing. I determined that I would build my wings dry and
this is a principal reason. The cost of 2024 T-3 extrusion will shock you,
and it is becoming far less than readily available. For cost reasons, I
found it necessary to purchase 4 12' lengths to get the 4 9.5 footers
needed. My supplier, one of the largest aircraft specialty materials
providers in the States indicated that he had trouble even ordering the
stuff. I spoke with the designer, Callby Wood, and he was quite insistent
that I use the 2024 extrusion on the main spar and spar web. There is a
quite significant strength disadvantage to using 6061 T-6, which is far more
readily available. I was very fortunate to have access to the thick (can't
remember now but believe it is 3/16" thick 2024 doublers at the root end of
the main spar. Good luck finding those pieces at less than a lot! The hinges
look like they will be a challenge to build and align so that the flaps and
ailerons work freely. I find no fault with the design and my technique may
be lacking on the joggling problem, but I have built all the ribs for my
Zodiac project from scratch with no difficulties encountered, and I didn't
give up on joggling until after I had exhausted my resources and skill.
I have long been fascinated by these metal wings and have recently
spoken with another man (Bill See in Centersburg, Ohio) who actually built
and flew a pair of the metal wings. he reported no difficulty, so you may
wnat to track him down. People search on Yahoo.com will turn him up. Anyway,
best of luck on the endeavor. It may alienate a lot of Tailwind people, but
I hate wooden wings, so I naturally looked at this option. Tom Wilson
