In re recent talk about tie-down ropes -- this may be more academic
than practical, but there have been recent MAJOR changes in cordage
(ropes, strings, cables, whatever) that may interest the List.
I just researched this subject for a boating magazine, and found that
the new synthetics are nothing short of amazing.
We all know nylon & dacron & polyester -- but the latter is very
seriously weakened by UV; sunlight. Don=92t trust it.
There are a lot of new fibers now, and some are FIFTEEN times
stronger than steel. A half-inch rope will theoretically hold TEN
TONS! (but don=92t stand under it)
But they=92re all different. Some are stretchy (we don=92t want that) or
very non-stretchy. Most are UV - sensitive and must be protected from
sunlight by a woven cover of nylon or dacron. No big deal.
The fibers named SPECTRA or DYNEEMA are reportedly the strongest
fibers ever created. Others are brait, vectran, lycra, twaron, PEN,
PBO, zylon, technora and others. All with different specs.
The bottom line is that there are some VERY strong ropes available
now. But of course there=92s a price. As I=92ve said, most of them are
UV
sensitive and should be protected. None of them like being knotted
very much; use splices and fittings whenever possible. And of course
they=92re expensive -- but you won=92t need a lot for your tie-down
ropes. And an adequately=strong rope may be too thin to grab hold of
and haul on.
The best place to find them is in marine stores like West Products,
or if by any chance you have access to a local sailmaker, pay them a
visit and ask some questions.
And bring your checkbook; something may be irrestible.

DVD:
Will your aircraft bump the redline, 6,500 rpm, WOT, straight and
level flight?
It should to get optimum climb and cruise performance.
This is why a ground adjustable prop is so convenient. One can dial
their prop right into the engine and aircraft, just like propping a
boat.

Yep. Replace it with a 66" Ivo 2 blade.

Richard:
Excellent advice.
However, if DVD does not pitch it correctly, might as well keep flying
the Tennessee Prop.
Bump the red line, WOT, straight and level fllight.

All this talk of props... My Ultrastar has what I assume is the original
2-blade wood prop on the Cuyuna engine... since one of the chief complaints
about the US is the prop ground clearance, would I be better off with a 3
blade prop of smaller diameter?

If the prop is presently likely to hit the ground, then you would be better
off with anything that is smaller diameter. I am presently using an Ivo 2
blade 68" prop on my MKIII, but even when it had a 2 blade 64" Ivo, it still
flew fine, just didn't accelerate or climb as well. Going to a bigger
diameter prop really helps climb, diameter is not as important for cruise.
If you can afford to give up a bit of climb, then the answer is probably
yes.

Richard/Dana/Gang:
The Ultrastar was/is a unique little bird. Flies like a champion.
Handles like a dream. Slow flight is its forte. Takes off and lands
by its self, long as it is kept above the stall speed (on my 1984
model would fly at 25 mph indicated, stall a needle width below 25).
Prop is not going to hit the ground. Not unless one breaks a main
landing gear. Problem with prop/ground clearance is FOD. Unless one
flies off a manicured grass strip or pavement, the prop will catch
Hell. Jim Culver came up with a polyurethane leading edge that helped
a great deal. However, taller grass, weeds, sand and rocks still took
its toll on the blades.
The perfect prop for the US was a Jim Culver 50X30. An US with a
Cuyuna ULII02 would just bump the redline at WOT straight and level
flight. That combo produced 85 mph. Not bad for a little UL.
Personally, I do not think going to a smaller prop will help much when
it comes to FOD and prop damage. Most likely will degrade performance
of a great combo.

Thanx Richard and John...
I don't know what my WOT RPM is straight and level, but with the Tennessee
it's 6800 just after breaking ground with a nose up attitude, tells me that
I'm way under-pitched...
Before it fell off, I had a Warp Drive, but I think I'll replace the
Tennessee woody with an IVO...
Maybe Santa has a spare on the sleigh, naw, probably not...
Thanx again...
