I agree with Richard. Simple trim tabs on the rudder and aileron, plus dihedral
go a long way towards making the FS a great pleasure to fly. I believe the
need for lateral trim is because it is very difficult to get both wings rigged
exactly the same - doesn't take much difference to build in a turn.
Another thing that made a world of difference with my FS is vortex generators.
They dropped the stall to 30 mph and the plane feels rock solid throughout the
flying envelope.

For some unknown reason, it seems all Kolbs with props that turn clockwise
want to bank to the left and yaw to the right. I think it has something to
do with the Coriolis Effect or maybe Sunspots.... Beauford should be able
to give you a proper explanation...
Anyway, trim tabs are a simple solution. Here are pictures of mine.
http://www.bcchapel.org/pages/0003/pg6.htm
I need to update the web page, because there have been some upgrades:
For the aileron trim tab, I now have RC airplane nylon hinges at either end
of the trim tab so that when I move the adjuster rod, the tab doesn't bend,
it hinges. I used large RC model airplane hinges, plenty tough for the
application.
I initially made my rudder trim tab a bit too large. Trimmed it down a bit
top and bottom with metal snips. Now it tracks straight with no rudder
pressure.
Once you get the rudder and ailerons tabs set pretty close, it will get
closer to flying hands off.
But it will not fly hands off unless it has a lot more dihedral than standard.
Our Firestar II N582EF will fly hands off, but it has about 5" of dihedral
per wing, way more than standard.
My MKIII has a bit more dihedral than standard, and it helps, but it will
not fly hands off. Almost, but not quite.

--> Kolb-List message posted by: "Bob and Jenn B" <tabberdd@hotmail.com>
Does anyone know what the limiting factor is in the 750 lb gross weight of
the Mk II? Was it structural with the 5" spar or was it because of the
performance?
For example, the Mk III is listed at 850 or 1050. That means structurally
it's fine but engine choice dictates the gross.
I know people have flow well above the 750, but is 800 or 850 safe?

Denny/others, when you lift up a bare block suzuki engine you think to
yourself, "this thing is so light it should levitate by itself" -don't
even
need wings. -But then as you bolt on one accessory after another, carb,
manifold, starter, generator, muffler, fill it with water.....
I read somewhere the 3 cyl runs somewhere around 145 with radiator.
I don't know the real number on mine because I bolt all the junk on
after
I mount it on the plane. BTW I have pared my empty weight down to 587.
If my CG will stand it I'll take the 15 lb lead weight out of the nose
and
be at 567.

Tell us the coordinates of your airport >>
Hi Robert/All,
Just in case anyone is interested a good aiming point is Keevil Airfield
where I learned to fly in gliders.Also where I saw my first tricycle u/c
plane, a Lightning, around 1942.
N51.18.54. W2.06.36
Track about a mile north to N51.21.48 W 2.05.21 and my field/ strip is the
Tommy Gun shaped field (with the barrel pointing North)
Between Keevil and my field you will see a long straight feature running
about East/West. This is a canal which connects the River Avon at Bath with
access to the river Thames. Track a little East on the canal and you will
see what looks like a series of odd small loops. These are the `pounds`
which store water for a series of locks , about 16 in this flight, which
lift the canal boats up to the height of the Salisbury Plain.
One of the wonders of the canal built by John Rennie around 1850 to move
goods between the Severn ports, Bristol etc., the coalfields of Somerset
etc to London.
What a super program.
Cheers
Pat

There is a way to counteract this force without using left rudder or any trim tab.
During a hard landing years ago, the nose of my plane was shifted slightly to the
left. The front part of the cage actually got shifted. It's hard to detect
even by looking at it straight on from the front, but it's enough to counteract
the yawing to the right and having to use left rudder in cruise. I don't recommend
shifting the nose around to achieve straight flight, but it does work.

Kolb List:
Finally, after a little over 3 months, the web site covering the fly in at
Homer's place Fathers' Day Weekend has been published.
My personal thanks, and I'm I speak for all the people who attended, to
Clara, Homer, their son Marcus and his family, and the friends and neighbors
who pitched in to make it a memorable day. Also thanks to Terry Frantz for
his efforts in coordinating between the Kolbs and the participants.
Since there was such a positive response to the one from last year, I
decided to incorporate both year's material into one site.
I hope it is understandable as to how to maneuver your way around the site.
Go to http://gtalexander.home.att.net and click on the link "NE Kolb

I would welcome any comments that you might have.

You're hired - couldn't be any worse than the idiot who did mine. He did it

the near future - if I get that s.o.b. oil leak fixed. New seal will be

Richard and others, the right yaw (not actually roll), is due to the tornado of
swirling air, from the prop, hitting the right side of the vertical stabilizer.
