Fellow Kolbers,
After attending Homer's fly-in I could not resist the temptation to get a Kolb,
again. I bought the early Firestar from Erik Grabowski that he bought from Bryan
Green who rebuilt it when he bought it from who-knows-who. I also bought the
trailer/mobile hangar, which I will no longer need after delivering the FS
to our hangar. So, I will have a Kolb hauling enclosed trailer for sale very soon.
When I do, I'll post specs etc.
For those who have not seen it, a photo is attached.

Hi All
Anyone flying to Oshkosh from the South West and need a stop I am located at
Morey Field (C29) and would be glad to help get fuel or anything else you
might need. We have two gas stations here that do not have alcohol in their
gas. It would be a good last stop because of its location from Oshkosh. I am
still working on my Kolb so I will not be flying to Oshkosh but will be up
there in my motor home but won't leave until the 27th. I will leave my Cell
number if you need to get a hold of me.
Thanks

Welcome back to the good side Thom. That looks like a nice plane. We should meet
up somewhere in the middle of the state some time.

Scott,
I first have to build an tail dolly for moving it around in the hangar behind the
Allegro. I'll have to fold and unfold the wings at each flight so I'm planning
on designing a dolly that will hold the wings such the the wing tips are above
the flying wires on the tail so I won't have to fold the tail with each flight.
At any rate, once I get used to the FS again, I'll give you a holler. Maybe you
and Bob Bean and Bob Erb and other Kolbers and I can make a little Kolb reunion
flight somewhere in the mid-upstate area.

I put Vortex Generators on my Kolb MK III Xtra. I did not want to post just a
first impression so I have flown with them for about a months so that I had a
chance to really try them out in a lot of different conditions. The VG's have
made a different airplane out of the MK III, not just in terms of reducing the
stall speed, but in the feel of the plane at lower speeds. It used to feel
like an approach speed of 60 MPH was needed to have a good margain of safety
and control. Now, 40 on approach feels fine, although I use 50 minimum as a safety
factor.
Stalls occour at 26 indicated, the plane is not really going this slow, as the
GPS shows mid 30's stall with no flaps. I have the traditional seperate flaps
and ailerons, and Stalling with flaps seems to be at the same speed as stalling
without them, mid 30's. The stall is really a non event, the plane shakes
1/2 second before the nose falls a few degrees nose down, Its so mild that I
have a hard time calling it a stall. Full aileron control is maintained throughout
the stall, if a wing starts to drop anytime in the stall, a medium amout
of aileron input immidately corrects it. I was teaching my wife stalls and of
course her first reaction was to jerk the stick back as soon as the nose fell,
she abruptly pulled the plane level at 33 indicated a couple times and never
got a secondary stall.
Yesterday evening, I wanted to see if I could really fly an approach at a very
low airspeed, so I went to 2000 feet, went to idle power slowed down to 35 MPH
indicated, and put in a huge amount of aileron, banked 45 degrees and roughly
jerked the plane around like an idiot, but was not able to get an accelerated
stall or felt like I was about to lose it.
Landings were a real problem at first, I was in the habbit of landing with no flaps,
and with the VG's the plane started to bounce badly on every landing no
matter how smooth the touchdown. The airplane would touch down, but there was
still enough lift being generated that it would fly again, even with a perfect
three point landing... It was worse with a wheels landing. Landing with one
notch of flaps totally cured this, im guessing that it pitches the nose down
enough that it does not tend to pitch up on a wheels landing, and its going slow
enough on a 3 point landing not to fly again. Now I land with flaps every
time.
The down side is that it cost me some speed, im not sure exactly how much as a
changed props at the same time I added the VG's, I lost 8 MPH in cruise with the
prop change and VG installation. Im guessing at least 5 of that is VG related.
I put the VG 's on with double sided automotive trim tape so that I could
take them off if I ever wanted to. Overall im so happy with the way the MK-III
flys and feels at slow speeds with VG's, I am more than happy to cruise a
bit slower.
I used 140 VG's spaced at 2.5 inches apart from the center out to the wingtips.
The VG's are in pairs and centered in the valleys of the ribs and face the airstream
at a 15 degree angle, and placed at 10 % of the chord of the wing.
Attached is a picture of the VG's on the wing, and my panel flying level with
3500 RPM just above stall.

Might want to rethink the prop change...having flown 2 different RANS
S7's with and without VG's and communicating with several that had flown
them on Challengers, you're the first I've heard of actually losing
cruise speed. A couple of folks thought "maybe a MPH or 2" but really
hard to tell. Personally I could not tell any lose of cruise speed.
Read an article in Sport Aviation long time ago about a guy that tested
VG's on an RV-6 with an articulating pitot-static test boom and
everything and got somewhere around 4-5MPH loss...but that was on a
200MPH airplane, so go figure.
Your still a good advocate for the VG's...even thinking that the VG's
cost you that much cruise speed you were impressed enough with the slow
end improvement to leave them on...that says it all. I'd bet a crisp $5
bill that swapping back to the original prop will show the VG's to not
have cost you much (if any) on the cruise end...

I LIKE that idea! Gotta see if I can do something like that for my US, if
I end up sharing a hangar instead of keeping it in the trailer. 'Course on
the US I'd have to partially fold the wings, keeping them outboard of the
stabilizer, but same idea.

Dana,
The space available to me for the FS precludes leaving the wings low and wide to
clear the horizontal stabilizer tips, so I have to tilt them up to keep them
within the width of the stabilizer. It should be simple to do and I have a plan
in my head. I hope to get it done within a couple days. If it works out well,
I'll take some photos and post them.

Very funny, George. Yeah, what airplane?? Also, notice how Mike
mentioned in his email how he had his lovely wife in the plane with him,
teaching her stalls, no less!!!! Gosh, should we be so lucky to have our
wives support us so!! I think it was a sly way for him to brag about having
a real sweetheart of a wife.
In case Mr. Mike reads this email, do you have any specs/details of the
VG's? Where did you get the design, and how far back from the leading edge
are they mounted?
Appreciate the
info, Mike in SW Utah

I will be flying in sometime Thursday late or Friday early and depart on
Sunday. If work doesn't get in the way again.
Does anyone know if the New Kolb gang is going to be at Oshkosh? I didn't
see anything on their webpage about Oshkosh.

| Subject: | Control Surface Hinges |
Hi again,
Time to permanently install my hinges.
Have read on other lists about bedding the hinges in Epoxy when riveting them
on.
This makes since to me because you are installing a flat surface to a rounded
surface. By bedding the hinge in Epoxy, the stress is spread out over the
whole hinge leaf rather then concentrated at the rivet holes.
I'm sure this is overkill ( many kolbs are flying successfully without this,
for many years) but still makes since to me.
My questions are these: Has anyone else done this?
How about inservice results?
What kind of Epoxy did you use? Considering using J-B Weld, but discovered it
is for steel.
Would it be appropriate next to aluminum?
Would it rust over time or cause galvanic corrosion?
Since the steel fillings are embedded in an Epoxy matrix, would it be an
issue at all?
All thoughts would be appreciated.

Yes, TNK will be at OSH. Display will be in the main area. Not in
the UL area.
Travis, how about posting the site number for TNK at OSH?
Thanks buddy,

As far as I know, there are no problems with piano hinges departing
round tubes on Kolbs.
Bedding hinges in epoxy is unnecessary, and will cause a serious
problem if you ever have to remove a hinge.
I have hinges on my mkIII, installed per the plans and instructions,
with well over 2,600 hours flight time on them. Have not had any
hinge problems concerning looseness.
Curious. Were the other lists you have been reading, reference epoxy
bedding of piano hinges, Kolb related/
Take care,

Never heard of that one.....
You could probly round the hinge tabs slightly to conform to the tubing...
But that sounds like a waste of time too....
One thing alot of the guys change about the hinge area......
Don't "crimp" them.....drill holes & use cotter pins...
That way you can take it back apart if you need to...

Okay guys. I have a couple of VW updates.
First, I have installed and have been test flying my new series three
reduction drive. As I reported earlier the new redrive is a serpentine
belt drive that slips in one direction at low RPMs and absorbs harmonic
pulses at higher RPMs. The VW redrive is smooth throughout all RPM
ranges and will even idle smooth down 700 RPM. This is a major
improvement over the old redrive. Since there is some slippage there is
a more limited life to the belts but there is a wear indicator that
shows you when it is time to replace the belts. It isn't known yet what
the life is but it is at least a hundred hours. The belt change requires
the removal of only one bolt, it is a one inch bolt but there is only
one.
Second, I've been working with Kolb on behalf of Rick Lewis to have Kolb
to produce a VW mount for his Mark IIIX. They now have the production
jigs to produce this VW mount for other MKIIIs. Hopefully Rick will keep
us up to date on his progress. I also hope he will build a bit faster
than Big Lar.

| Subject: | firestar prop size? |
Hello everyone. Does anyone know the recommended prop size for a Firestar I with
a 447. I am not reaching full RPMs. My plane has a wood 66x33 which I am
guessing is my problem. Any ideas?
Thanks,
Bryan Dever
