I won't answer your question about "tripping" or
"turbulating" an airfoil because it really is horribly complex and
situation-dependant. Here's some info in the "Aerodynamics" section of Dr.
Martin Hepperle's site:

Hi Guys to add a little more to this thread I did a little more research
on the net, talked to a number of suppliers here in Australia and have
come up with a design for a machine to wet out the tows.
It will consist of a vertical length of PVC tube of 35mm dia. closed at the

Ok... ok... ok OK. I can't resist. ;-) If
you want weaker... slower... heavier... larger... and
more expensive I'd use the JR 368. ;-)
Otherwise, the new Airtronics digital would be a good
choice... 94761.

Hi Shawn,
I don't think anyone has long music wire...
Try a weld shop. I have used weldingwire. normally a weld shop will give you 15 feet or so. it comes in different diameters and is not hard to straighten out enough to work. I have used it on a couple of different planes.

I tried a music store, and they seemed willing to help - it
was very busy, and I had to leave, but they acted as thought they had spools of
wire for the pianos
Maybe?Good luck,
Brent

If you don't have to make bends, carbon-fiber rods work great, are lighter, and can be had in 4 and 8 foot lengths:

You can get long music wire from www.smallparts.com, or from any piano
tuner. I got a huge roll from an on-line piano parts company, a
lifetime supply for sixteen bucks if I recall right.
I later found it was easier to get stainless-steel leader wire from
Bass Pro Shop. It's not as stiff as music
Bill,
This is .018 wire for a DLG. You can practically tie it in a knot. It
needs a housing to take shape. The curve from the coil goes away as soon as
the push rod is in the housing.

It's the "Darwin Award" equivalent for true F3B and F3J pilots in
Europe.
The "Gorilla" and Flywheel winches were descendants. Somehow,
someone made it through their first launch.
