Jerry, I shortened my wingtips by 7 inches on each
wing in order to get the plane through a 28' door with
a little clearance. I just pushed the tips in till
the curve started and riveted all the bracing back in
place. I saw Homer at Oshkosh and got his approval.

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.
