| Subject: | Re: Mark III for sale |
Sorry I should have given more info in the first post but I guess I'm so upset
about having to sell that my mind wasn't working. This is a Mark III extra located
in Kingston, Tn. My phone number is, 865 376-1450 if anyone wants to call
and talk about things, I won't be home Saturday. The wings and tail feathers
are all completed and covered. The fuselage is not covered but the windows
have been fitted and cut to size, ready to mount. This would make a wonderful
plane for someone to finish out, talk about buying a quick build. I must have
18k for the plane, even still this will be a loss to me.

I'm not sure if it would be the same for a Kolb...but for the Challenger the toe
in is 1%. The easy way to check this is to put a straight 2x4 in front of both
tires and block it up so it sits at axle height. Then take a square and place
it alongside the wheel and measure the distance between the square and the
front and back of the rim. The front measurement should be 1/8" more than the
back measurement. See the following link

Eugene,
Nice concept... I'm surprised the Kolb company doesn't offer that as an option.
Thanks for the post !

| Subject: | Re: landing gear alignment |
There is always a big controversy concerning toe setting on airplanes. The toe
setting has absolutely nothing to do with whatever you learned about setting
toe-in on cars. Generally on pavement, the airplane will go in the direction
of the wheel with the most weight on it. On grass, toe setting almost doesnt
matter at all. In my mind, for a tail-wheel airplane (not a Challenger), I would
strive for zero toe and camber; both set at normal flying weight (with pilot)
and err on the toe-out side. My reasoning is that a slight toe-out would
tend to lift a low wing (heavy side). The Challenger is a nose wheel type airplane
with main gear located further aft and the above probably would not apply.
Of course, I could be totally full of crap too!

Sorry to hear you are having to sell your Kolb. For those that aren't
aware Rick was instrumental in getting Kolb to produce the VW mount option.
Also the water cooled heads are a very rare option that fixes cooling
issues on the VW engine and increases power.

Toe out and pavement on a Kolb, any model, don't get along. Causes splaying
of gear legs and scrubbing of the tires, not to mention problems trying to
second guess where the airplane is going.
I set up my MKIII to nearly zero toe in/toe out, leaning on a tad of toe in.
If you want a number, try 1/16". Rolling forward, my gear remain nice and
straight. Landing and taking off on pavement, my MKIII has no bad habits or
surprises. Push the airplane backwards and the gear legs splay out. They
also splay out when making a pivot turn either direction.
Kolb gear are flexible in 360 degrees. They are not locked into place like
a car, truck, tractor.
After 3,200+ hours on my MKIII, no tire problems. This last pair of 8.00 X
6 Airtracs probably have 1,500 to 2,000 hours on them, guessing without
looking in the log book.

I did some work a while back on a spread sheet and did some what if's.
by putting a straight board, or I used a steel angle supported with
sections of 2x8 to hold it at the correct height. and held against the
back of both tires. then used a carpenters square to hold against the
straight angle and the side of the wheel. this was done with
both wheels sitting on grease plates so they could move and rotate
freely. the grease plates are made by putting a layer of grease between
2 layers of aluminum,, or in my case I used some 1/8 inch floor tiles.
I measured the distance from the edge of the square to the
front of the rim and back of the rim. if the tire keeps the square from
touching the rim,, measure the front and back and use the difference.
my difference was 0.052 inches
the tangent of an angle equals the measurement of the opposite side
of a right triangle divided by the adjacent side. but knowing the
opposite and adjacent sides, we can use the inverse tangent function
to find the angle. the inverse tangent function
the ratio .052/5.725 or TAN-1 power is .52 deg Toe In.
ok before the math wiz kids flame in, I said I measured the rim,,,
well I measured the rim at a point equal distances from the
edge of the rim so the measurements points were 5.725 inches
from each other. using the spread sheet, I found a nice relationship
between measurements 5.725 from each other and the solution to the
problem. that relation ship was the angle in degrees was ten times
the difference measured in thousandths of an inch.
so a difference of .052 equals .52 deg. and again from the
spread sheet, if you measure the 6 inch rim, the difference
in the degree of angle was negligible compaired the the 5.725.
I should also note that this relationship only survives
if the angle is small.
so plugged into my spread sheet,,, your 1/8 th of an inch or
0.125 times 10 equals 1.25 deg toe in. the picture in your link below
was identical to what I did, but I put the strait edge on the back
instead of the front of the tire. that is a very good picture
and explanation.
on my mark iii I have the solid tapered steel legs purchased
from kolb. the sweet spot for my plane was 1.22 deg toe in total..
half of that, or there about, on each wheel... 0.52 on the left
and 0.7 on the right.

Rick, so sorry you are having to discontinue the building of your plane and sell
it. I understand but am saddened for you. Want to ask would your exhaust fit
my MKIIIX with GPAS VW, 2180 c.c. with re-drive? If so would you be interested
in selling it separate? If not, where did you get the exhaust system made
up?
I appreciate your reply.

Due to health reasons I will have to sell my plane. I'm needing 18k and I'm taking
a real loss here. The wings and tail feathers are all covered, the water
cooled VW engine with series 3 redrive is included. I figure about 70% of the
plane is done.

Thanks Rick for that post, I knew you would step in and say something good about
what I have to offer. Who ever ends up buying this plane is a lucky person.
There are so many options they will be getting for such a good price. The kits
cost new and the engine included cost less than the Rotax 912 engine alone,
what a deal for someone...

Rick, I'm interested in your plane, but can't buy one for awhile yet. Yours needs
fuselage covering and what else? I assume it's not yet N-numbered. You have
logs & paperwork? Trailer, or is one available locally? Is that a GPAS engine?
What cc; 2180?
Thanx
