Subject: | Esqual v Lightning Question |
I read the 2003 EAA article, that someone posted the link too, about he Esqual.
If I remember correctly, it says that you can get it in either fiber glass or
carbon fiber and that the carbon fiber model was about 60 lbs. lighter. Does
anyone know why Arion decided not to go with the carbon fiber with their design?
Thanks,
Rick

While I dont recall the numbers, the carbon Fiber Esqual was substantually
more money for a weight savings of 60 lbs. They only sold a few of them.
We all agreed it was not worth the money.
The Lightning uses a small amount of carbon glass around the spar.
The Lightning molders are using some state of the art techniques that result
in a lighter composit using cheaper materials that are easier to work with.
The carbon mat is rather unreasonably priced. I would guess that to do all
carbon would nearly double the cost of the kit and save only 30-50 lbs.
Just my opinion.

I can't speak for Arion, but my guess is that the weight savings vs. the
cost were prohibitive of going with CF over just glass. They do use CF in
stratagic parts of their design tho...

Doug is right on about the cost vs. weight savings. For a 60 pound weight
savings the carbon fiber Esqual was 5 to 6 thousand dollars more depending on
the EURO exchange rate at the time. Now it would probably be even more since
the Euro is stronger and carbon fiber cost continue to go up as well. Plus
carbon fiber material is kind of hard to get. It just is not worth that kind
of cost for the type of sport aviation mission we have.

Colin, one tool I forgot to mention. A real good vaccum cleaner. When
you start working with the fiberglass you will understand.

I just weighed my glass Esqual a few weeks ago. 325 kgs, 716 lbs. The only carbon
version I know of weighed in at more than that. Had a few toys in but I have
a set of old analogue instruments so I figure it was actually a heavier airframe.
The cost difference was 4k 4 years ago.
I was talking with the Dyn Aero Ban Bi distributor in the UK and he said that Boeing
and the airlines are buying up all the carbon that is being produced which
is driving the price up.
The original weight of the Esqual in my build manual is stated at 275 kgs, this
was when they met the 450 kgs MAUW required to be ULM aircraft. I do wonder where
the extra 50 kgs comes from. The basic airframe doesn't have a big parts
count so where did all the extra get added in?
Maybe Pete figured it out when he developed the Lightning in a similar concept?
I have to say when lifting them the wings feel a lot heavier than I would have
thought they were going to be.......
.
Regards, Clive
