I'm surprised more LSAs are not going to the tube and fabric way.
Might help get the price down under 100k.

Some are and Steel tube is a good way to build an airplane.Very safe
The problem with old wooden wings is twofold. Glues that encouraged various
organisms to grow and moisture getting trapped in the structure. Bellancas
are pretty straightforward from what I understand. At least compared to
some really scary structures like the Cessna Bobcat or a Fairchild PT-19.
Wood spars OTOH, are a good thing pretty much no matter where they are.

Bertie

I haven't really looked, I suppose.

My dad is a fan of the Challenger.

The local enthusiast has a very light something in the big hangar at
VVS - the seat looks like a diaper and the engine came from a Lawn
Boy... yikes.

LOL

Yeah.. exactly.

It's not flying as much as being suspended from a temporary truce with
physics.

No Thanks.

That's what I heard before. Makes you wonder. Who would have
thought of that? "Oh, buffeting, let' s swap the engines and see

engines wrong and someone said, "Hey, this thing performs better
this way". You can see I have a lot of confidence in American
ingenuity.

Should have looked here first

http://en.wikipedia.org/wiki/P-38_Lightning


This seems to be a pretty accurate account of the teething problems
the airplane had and the remedies they used. i'm pretty sure the prop
rotation was part of the buffet solution, but this article seems to
indicate otherwise.

LeVier did a lot of the high mach number dive tests in the 38, and
there definitely was a compressibility problem, mach tuck; the whole
works. I know they added speed brakes but not sure at exactly what
stage. The engine rotation switch was early on in the program
according to Ethell; I believe in the YP38 stage before the first
production run. If I'm not mistaken, the high mach dives came after
the switch but I'm not at all certain of that.

Me neither. I did find one farily hilarious account of the airpanes
early flights in an old period magazine. The story is abou tBen Kelsey
one of the test pilots, and his transcontinental flight. Apparenlty he
cracke the thing up on landing after some sort of harrowing experinece
which left him babbling and he had to be hospitalised, with G-men
gaurding his bed. The aritcle goes on for several pages about how fligt
at high speeds like the lightning achieved, was at the ragged edge of
what even a superhuman could withstand mentally.
Those were the days!


Bertie

Yeah. That entire gang out there at the Skunk Works were a hoot. Kelly
Johnson was a hell of a designer.

I'm sure that Johnson as well as others like Ed Heinemann and Jack
Northrop, Alex Kartveli, and Dutch Kindelberger all benefited from the
work done by Lippisch and the others who came before them.
I've always been intrigued by the work Lippisch did on tailless
aircraft. His work on wing design was WAY ahead of it's time.

Any thoughts on why the canard never gained acceptance?

The Wright brothers thought it the optimal solution.

Mind you, some of the thirties ones do appeal to me. The Longster, The
Church midwing and the Piet, for instance, but they're all somehow real
airplanes..

Aeronautical genius, perhaps.

Marketing -- not so much.

All the -38s sold to England had same rotation direction engines on both sides all the way through. Just another odd
thing...

Got a link or a pic?
