--> Kolb-List message posted by: "Jim Ballenger" <ulpilot@cavtel.net>
Kolbers
A few weeks back there was a posting from someone on the list with the dimensions
of a 10 gallon tank from Titan Aircraft. Since I was looking for a way to increase
the amount of fuel carried aboard the Xtra, I ordered two of the tanks
from Titan last week and took delivery 2 days later. In order to fit them inside
the cage, I cut the 1/4" tubing that holds the factory 5 gallon tanks in
place. I will replace this tubing with some material to hold the larger tanks
in place for flight. The good news, there is plenty of room for the larger tanks
and the CG should not be affected that much, the bad news is I will need to
place them in the cage prior to covering.
I took some pictures, so let me know if you want me to send them to you off list.

Kolbers,
I'm getting ready to take my steel parts to the local body shop for painting. I
plan on having them prime and paint with 2 part urethane. What should I do if
anything to the insides of the tubing? Also should zinc chromate be used under
the 2 part primer?
thanks

Paul, any preservative (tubeseal, thinned-down linseed oil) should wait
until the tubes
are painted so they won't have surface problems. If you are going that
fancy with
urethane I wouldn't worry about chromate, not much will get through that
stuff.
I still need to seal off a few holes myself. A dab of paste epoxy like
JB weld will
do. -BB

Another thing I need to be caught up on -- what is so dang hard about
the per plans fabric gap seal? Is that the TNK plans method these days
or do they recommend book tape? Maybe the method depends on which
model plane? For the record, I thought the 2" fabric gap seal on the
firestar was easy -- and my threshold for "difficult" is pretty low! :)

Paul,
You should probably locate and drill the tiny holes for the linsead oil
prior to painting the exterier of the tubing, than after painting all you
will have to do is shoot the oil in.
I wish I could have done this, also might want to locate the holes so you
can put the oil in after covering and painting the fabric.

Would the new owner of R Bakers Mk111 contact me off list. Ray it has been
good talking to you once in a while. Thought we would get to fly some together
once I got moved down here. You take care now.

| Subject: | Vortex generators installed |
--> Kolb-List message posted by: Richard Pike <rwpike@charter.net>
Got busy this afternoon and made 20 vortex generators and went out and
stuck them on the MKIII. Had previously examined Vince Nicely's Firestar II
with his vortex generators and after we discovered the airfoils were
identical, I used his numbers to locate where I installed them on the
MKIII, as he had already done extensive testing to find the sweet spot to
locate them.
Flight testing was with mixed results, mainly because I think my airspeed
indicator is terribly non-linear below about 40 indicated, so I can't tell
if it is flying/stalling any slower or not. It feels like it is, for what
that's worth. It still stalls at the same indicated airspeed as before (26
indicated, 35 actual according to the GPS), but at a much higher apparent
deck angle. The stall is slightly more aggressive than before, it has a
clean break, both straight ahead, power off and accelerated, but still
fairly mild & easy to live with.
I may have lost a few mph top end, it seems to have dropped from a max
of around 90-92 down to about 88-89, could not tell that it was any slower
at 5000-5500 rpm cruise speeds.
The good part came in the landing configuration. Practiced at 3500', full
flaps, power off, and tried descents at 50 indicated and simulated a brisk
flare. Always before, it would start to flare and then sort of mush out the
bottom, but this time it felt solid. So I went home and shot a couple
landings at a 50 mph approach speed. (Normally I use 60) Power off, no
power added to round out and flare, full flaps, and I still get to use the
airplane again tomorrow, didn't even need to order new gear.
It was well behaved and landed normally. However, as soon as I started to
round out, the airspeed indicator was falling through 45, and if I had any
excess altitude, it would have been ugly, because it got slow real quick.
But it stayed well behaved, was still holding off the first time and
touched the tailwheel first.
I am satisfied that I can now shoot approaches slower with more security.
So although I don't know if the vortex generators have changed the stall
speed, they have certainly improved the landing characteristics, which
makes them well worth the three hours it took to make them and put them on.
I used soft aluminum gutter material, before bending they measured 3.75"
across the back, 2.75" across the front, and the ends are bent up 3/8" ,
they are 1.5" deep from front to back. The front edge of the vortex
generator is 11" from the centerline of the leading edge. They are secured
with one rivet into the rib 3/8" back from the front, and then the rest of
the underside of the vg is coated with
Goop glue before I rivet it in place, keeps it from moving against the
fabric. They have a little bend in them through the center to make them lay
down against the fabric where the fabric goes over the rib.
I used ten vg's total, starting from the outermost full rib (not the little
one that is part of the tip) there is one on every third rib (full and
false) for seven ribs, which puts those seven ending up on a full rib, and
then the last three inboard are on every fourth rib, which are all full
ribs. That keeps the innermost ones out from in front of the prop arc,
which is good, because you now get a power on real loud prop yowl and
buffet well ahead of the stall as the center section starts to let go
first, good stall warning signal.
Sorry to rattle on for so long, but I have been looking forward to this for
quite a while, and it was fun to see it come together.

Ben,
The fabric tape is fine and should be choice number one for builders of any
model Kolb.
Some of us choose the book binding tape, I did because I did not want to
attach my control surfaces until after painting, and also we saw some planes
at the 2000 TNK fly in with the book binding tape and liked the look.
Totally a personal preference thing.
Just make sure you do one or the other to a Mk-3 because the differance it
makes in the ships performance as compared to no tape is astonishing.
Sincerely,
Denny Rowe

Kolbers,
If anyone talks to John H, tell him if he is planning on passing through
South West PA to give me a call at 724-845-1431. I would love to hook up
with him and show him my bird if he is going to be in the neighborhood.

Hello Everyone.
I own Mk2-171 and I suffered some damage to the fiberglass tailspring. I want
to take out the old spring and replace it with the newer spring aluminum rod.
Anybody have any experience doing this with their Kolb and how did you accomplish
it?
Thanks up front for any help with this.

That's neat but that mighty heavy. I figure my VW is at least 45-50 lbs
lighter and three thousand dollars less. My plane weighs 554 lbs empty when
I add me 210lbs plus 60lbs fuel I have to limit the weight of my passengers
to stay below the max gross weight. If I were to add another 45-50 lbs I
would almost have a one passenger airplane.

Reread my earlier post about the vortex generators -
At one point I said I used ten vg's total -
that should have been per wing.
20 total for the airplane.
