Why 2024? by
Lou
My plans call for the use of 2024 1.5mm to use in the forming of
brackets
that will hold the bellcranks. Each part is doubled, (left and right
bracket
top and bottom parts on the bellcranks), so it seems to be extremly
strong.
Now, don't get me wrong, I can make a call today and order the
material...

Why 4130 tube? by
Leon McAtee
Why do we homebuilders use 4130 tube? My old Aeronca does just fine
being made of mild steel. A bit of napkin calcs says that going up
just one tube diameter for the size tube we normally use, the area,
and the strength/weight goes up between 15% and 20%. This pretty
much offsets the difference...

Why are low-revving, high torque engines preferred? by
Oliver Arend
This may sound like a stupid question; I realize the prop can only
turn at a certain speed to avoid transonic effects at the tips and has
to be turned with a certain torque to transmit the power needed/
produce enough thrust. So far so good.
But why does the torque have to be produced by the...

Why do you build airplanes? by
cavelamb himself[_4_]
Personally, I've never enjoyed anything as much as the act of creating a
flying machine. Well, ok, there was sex back in my young and dumb days.
But for me - it's the act of creation.
I suspect others may have different thoughts.
Anybody care to share?

Why don't wings have dimples 2 by
Dancing Fingers[_2_]
Last night the Mythbusters put about a 2 inch layer of clay a a sedan
and drove it at 65 mph and recorded their mileage. They put dimples
in the clay, like a golf ball, and repeated the same test and got 11%
better mileage. This again begs the question why don't wings have
dimples, especially for...

Why don't wings have dimples? by
Dancing Fingers
Hi all,
I always wanted to build my own airplane but the time and money has
eluded me. So I've decided to design and build my own recumbent trike,
with farings. This brings me to my question, if golf balls have
dimples, to help them sail further, why don't wings -- especially for
STOL aircraft? ...

Why get mad at Zoom? by

He's nuts. But he's not a pegboy like Collins, McLellan ad nauseum.
And he's not a Poberezny, fleecing all you SUCKERS.

Why is it so hard to find # seats for aircraft??? by
Adam Aulick
Just venting here.
Why is it so hard to find out how many people fit in airplanes?
Visit the Murphy Rebel page
http://murphyair.com/Product_Info/Rebel/Description.htm. I see you
can install a third seat "if your family expands." That's great! Do
they mean that literally (3-pax airplane)...

Why is this so familar? by
John Ammeter
I'm currently in the same situation. I bought a Cendyne DVD burner,
advertised with a $30 rebate. The company was already in bankrupcy at
the time of the sale. What can be done about that? They were
advertising a drive with a rebate that there was no chance of getting
back.
That's...

why isn't there composite tube fuselage design? by
Shin Gou
I am just wondering...if composite materials are stronger and lighter
than steel, why composites tubes aren't glued together to form the
fuselage frame just like the traditional 4103 steel tubes being welded
together? Any reasons?

Why no new diesel radials? by
On-Condition
Just wondering, exactly why are radial diesels not part of the
diesel revival? You can't beat radials on airplanes for smooth
reliability. I once saw a cracked-off jug pounding through the
cowling as the engine was still running (the single Otter had
just landed).

Why no plywood monocoque homebuilts? by
[email protected]
Howdy,
After reading a bit about the early Lockheed Vega, the Focker Albatross
DIII and the Dehavilland Mosquito I was a bit suprised that plywood
monocoque construction hasn't been used in any more modern airplanes.
(Or at least none that I can think of) What gives? Is it cheaper to use
glass...

Why so many rivets? by
Brian Sponcil
I'm currently considering embarking on an RV project and after checking out
a few in our local EAA chapter I ran across a seemingly curious fact. I
recall the builders telling me that their RV kits have around 10,000 rivets.
Compared to a Piper Comanche at 3,714 and a Warrior at 1,785 that's a...

why so slow??!! by
Heino & Deanne Weisberg
I have a Stitts SA-3A playboy I picked up recently. It has an A-75
Continental and a 67" Fottorp prop with a 47 pitch. The plans indicate this
machine should fly around 120 mph with this engine; no mention of prop. A
previous owner I spoke to said it cruised around 118mph for him. For me,...
