--> Kolb-List message posted by: "Richard Girard" <jindoguy@gmail.com>
Even though I have gained proficiency in straightening the main gear legs on
my Mark III and have the job down to less than 4 hours to remove, straighten
and reinstall them, I'd like to avoid the experience if I can. I have 6"
steel wheels on my Mk III and until a few days ago they carried 15" X 6" X
6" grooved lawn tires. Then I discovered that Spruce carries an 18" X 6" X
6" turf tire. Running tubes in them I can drop the pressure to 8 psi. It's
like having Nerf tires. Five landings so far and they're great. Now that I
don't worry so much about bending gear legs, my landings have improved and
I'm rolling it on nicely. The Nerf tires also give a nicer ride when
taxiing. As for cost, well,it's $140 no matter which you choose. New Legs
$140. Press to straighten old bent legs $140. Nerf tires $140. I did both
the latter, but I straightened the set 3 times, so I'm actually up $140.
Maybe it's the right time to go to Vegas.

Has anyone shortened the bow tips on the wings of Firestar? Seems to be a lot of
drag out there. Doing some measuring, 6" could be done pretty easy. That would
be 12" less of nonlift producing drag gone.

Not sure about the FireStar, but a few years ago, Ron Christensen built a
much modified Kolb that he called the Mk III 1/2. It gave me several ideas
for Vamoose. There's a couple of pics of it on one of my Vamoose webpages.
He originally tried just what you're asking, and lost performance. Then he
built several variations of wingtips, including drooped, out of fiberglass.
He did a beautiful job, but finally wound up with stock wingtips, and said
they performed best. Lar.

Jerry,
I'm not so sure that the tips don't produce lift. My original Firestar had stock
tips and my Firestar II has shorter tips. I suspect that they do. If I ever
build new Kolb wings they will have stock tips.
do not archive
