In an issue of RC Soaring Digest a couple of months ago I
saw a writeup and an ad from an outfit called Elf Engineering in
Wylie, Texas. It turns out the impressive name covers a one man
shop owned by Dale King. Dale will build a glider wing for
approximately $225 to your specifications. It's made of blue
foeam sheeted with obechi and comes in either plug in or three
piece.
I have been unhappy with the size of the Legend flaps so
I decided to take a chance and order a set of wings to my
specification. I chenged the airfoil to SD7037, lengthened the
center section to 54", shortened the outer panels, reduced the
dihedral, and maintained the Schuman planform to create an "anker
Special Killer Wing".
The wings arrived a couple of weeks ago and I have been
going real careful to make sure they came out well. A couple of
booboos were inevitable (at least for me). I managed to sand
through the obechi in one place. But overall I'm really happy
and decided to polyurethane the wing to let the natural wood
stand out.
Yesterday I was ready for the big test. First off the CG
was too far back. This is the first time I have flown a glider
that tucks in the glide test. Talk about excitement! Every time
I touched the stich it would either climb to a stall or dive
towards destruction! Even then I managed to find a thermal and
get a half decent flight. After getting the CG straightened out
I had several great flights, terminating in one where I decided
to go for my 1/2 hour flight for ESL level III after Flying for
quite a while. It took a little while to get the witnesses
straightened out so the flight ended being well over the 49
minutes I clocked. At the end of the flight I made a try for the
1km goal and return, but the spotters failed to spot the plane,
so I'm goinf to have to try that some other time. Anyway, I have
never had this good a set of flights with a brand new set of
wings before. They really are killer wings and well worth the
money. Being able to create a custom plane without doing all the
building yourself is just my ticket.
If anybody else is interested I have an oreder form at
home.

Useless footnote: My parents live in Wylie, TX. It's a dusty little
town just outside the "Dallas" area. (Actually northeast from Plano.)
I'll have to visit Elf Engineering on my next visit to TX. It's
also interesting to note that Wylie is where RCSD is published...

Anker,
What kind of spar does the wing have? How much does the wing
weigh?
Thanks,
Jim

Re: <<< Note 1463.2 by UNYEM::BLUMJ >>>
Jim,
The spar is balsa with air-ply shear web wrapped in
kevlar. The top and bottom of the spar is covered with carbon
fiber during layup. All this is taken from the writeup. The
spar isn't visible anywhere. The complete wing with servos
installed and painted with polyurethane is 44oz. This isn't a
floater wing. The fuse comes in at close to 50oz, so the whole
plane is at roughly 94 oz. This has to be considered in the
context of the wing area which I guess is roughtly 1100 square
inches. The wing loading end up being about 12.5 oz per square
foot, which is fine. I'm personally more than prepared to pay
for the increased stability of blue foam with a weight penalty.
With the original Legend wing the plane weighed in at 80
oz and a wing loading of 11.5 oz per square foot.
There is a small amount of flex in the wing during
launch, which siuts me fine. With the original Legend wing there
is zero flex and the first indication of too agressive launching
is the ailerons fluttering.

or the wing going BOOM as Steve Schommer's did at the Nats Just out of curiosity... how was the wing packaged for shipping and what was the actual turnaround time after you got all the design details (and money) to him? | |||||
| 1463.5 | Top class packaging and just under three weeks | MR4DEC::ANKER | Anker Berg-Sonne | Tue Oct 20 1992 14:40 | 13 |
Re: <<< Note 1463.4 by HANNAH::REITH "Jim HANNAH:: Reith DSG1/2E6 235-8039" >>>
Packaging was superb. The panels were in the cores they
were cut from and then there was a ton more foam to fill the box
completely.
He did the wings in under two weeks and UPS took a week
to get them to me. He and his wife were also really good at
calling me back when I called to ask where they were (I had
expected a two week turnaround expecting a bit too much from
UPS).
