Sure it is. It's still beautiful. I'm already thinking about when I can get down
there in my Firefly. Maybe next winter. Thanks for posting this video!

One day we will have a Kolb Video, I will make one when I go :) Dont know if
it will be this year or next, depends on work, but watching those videos makes
me want to go all that much more :D

Naw!
That video does not begin to share the wealth of beauty one
experiences in a Kolb flying Mounment Valley.
After flying MV for four years now, I can assure you, your first
flight in a Kolb will blow your soxs off.

| Subject: | Re: prop hub extentions |
Mike,
I still have the black tapered hub if you want it. Dont know if the prop side is
the same bolt circle as the Kleiv but your welcome to it. Two things I noticed
about your photo are 1. your prop hub doesn't seam to be completly sandwiched.
Is this normal? 2. Why did you go with castel nuts and cotter pins? Just curious....
One more question does the Kleiv hub have the larger diamater bolt
circle with the bored holes for the rotax lugs? From evey one i have talked to
the rotax lugs and 8mm bolts are the strongest combo for what it's worth.

Hey gang lets talk nose cones. I am not real happy with mine as well as others.
I know the fine folks at TNK do their best with these and for the most part they
are holding up but mine is like paper thin. It will crack if you look at it
funny. Wonder if Uncle Craig would consider making us some carbon fiber nose
cones with perhaps some special reinforcements where we might like to mount say
an antenna or something elese?

I am a bit confused as to how you would ground the coax at the radio end.
There is only a BNC connector at the radio end. Sorry, but you are going to
have to be a little more specific for me. :{-)

if you are using a handheld it would be difficult..... but if you have a
panel mount... it is more than likely grounded through the mounting
hardware. On the antenna end the grounding would depend on what you are
using for a ground plane.

Somehow I doubt that running coax Through a ferrite ring/loop will alter the
electrical length, Tell me how this works?
regards,
Bob N. FireFly 070 Old Kolb
http://www.angelfire.com/rpg/ronoy/
chokes and coils are funny animals, especially when hooked up to radios and
antennas. But in short,,, by running a coax through a ferrite ring will
in effect create a transformer, in that some of the energy traveling
through the wire will cause movement of electrons to run around the ring.
This would stop the offending energy from getting to the radio or from the
radio to the antenna... Depending on the frequency of the interference
and the number of turns around the ring, the size of the ring, the
offending interference can be eliminated.... but on the other hand some of
the RF signal can also be eliminated. As to the electrical length.... it
could or will have an affect on the impedance which could cause you to
change electrical lengths to compensate. but chokes and coils work
generally in 1 of 2 ways... they are designed to block a signal,,, or pass
a signal... what we would want on an antenna would be a pass filter,
designed to pass all of the radio signals in the range we want to use and
block all others. Or if you have interference at a specific frequency,,,
you would want a notch filter to eliminate the offending interference. And
unless you are more skilled than I,,,,, the production of these devices is
not best achieved by a back yard experimenter.

Thanks for the tutorial, Boyd
The current flowing on the inside of the outer conductor, and on the
outside of the inner conductor in a coaxial transmission line will
have a difficult time being affected by a ferrite choke; in an open
wire, yes. BUTT, maybe things have changed of late. Speaking of
backyards, some 40 years ago I had a 25' dish, with a homemade 1KW
transmitter on 432.000 mHz aimed at the moon. Had a sked with dentist
in Zurich E-M-E from Cedar Rapids.
