It is a good idea but it only produces a longer time before all the oil is
pumped overboard; a longer time to find a landing area.

There's something about it in the regs for certificated planes, I go
with the elect sender
type also, less messy, less risk, however if that's the route you want,
use a restrictor
fitting (AN flare) at the engine, and hydraulic hose. Then all your
pressure drop will be
at the orifice.
Don't use a capillary line for any distance because of the horrendous
lag time in the
reading. -BB do not archive

Hi John W. and Gang,
John, was curious about why you are switching to the Verner engine. I haven
t saw anything posted on this other than you are installing the Verner. Isn

--> Kolb-List message posted by: "John Cooley" <johnc@datasync.com>
Hi Gang,
Would like to hear some pro's and con's on installing a cockpit adjustable
trim tab one of the elevator halves on the Mark III. The Twinstar Mark II
uses one and they work very well. Not very pretty but neither is a big ole
trim tab on the rudder to offset the P factor of the Rotax 912. Is anyone on
the list with a Mark III using this setup. One big advantage is that it
could be used for pitch control in the unlikely event that a elevator
control cable became inoperable. Any thoughts on this?
Later,
John Cooley

John C/Gang:
On the original Twinstar, the adjustable elevator trim was
the cause of a fatal crash. It is in the NTSB archives.
I have no problem with the basic pitch trim on the Mark III.
I did change the actuator on mine, but the basic design
is still there.

Hi
On a manual oil gauge the oil line is very small not much larger then the
wire that you would use. The likelihood of that line braking is very slim. I
thought the same way till I did some of my own experiments with the line. I
also checked with some of Rotax Tec. people and they say that a lot of guys
are going manual and that's ok. I when though two sender unit and checking
both when I install them nether was very accrete. If you can't trust your
gauges what good are they.

You got that right. I have never had an electric gauge on
the 912 or 912S that was reliable. Now you got me thinking
about a mechanical gauge. They do not lie, for the most part.

Here is the url:

The narrative indicates the adjustable elevator trim was not
a factory design. However, IIRC the original Twinstar did
have a factor cockpit controlled elevator trim tab.

IIRC that is about the size of the cockpit adjustable
elevator trim tab on the old Twinstar. I never flew one, so
have no idea of how effective or over effective it was.

John C. and fellow listers,
I have had several inquires about my switch to a different engine on the
Kolbra. I will try and explain some of my reasoning.
I had this Jabiru 2200 engine in my garage for another project that didn't
work out and the Kolbra was the only tandem seat aircraft that advertised
the use of the Jabiru that interested me.
The Jabiru has proven to be a very dependable engine for me but it has had
some short comings.
The slow speed of the Kolbra does cause the engine to run near the CHT
limits most of the time. The engine just doesn't get the volume of air it
needs to stay cool.
The direct drive forces you to use a fairly short propeller so the take-off
and climb performance isn't as good as if it was powered by a Rotax 912.
I do not favor one brand of engine over another and the new Verner 133M on
paper looks like a very good alternative to the Rotax.
I cruise just fine pushing the Kolbra along at 80-85 mph and burning about
4.2 gph with the Jabiru. The Verner is advertised with a smaller fuel burn.
Hopefully the new three blade prop turning a lot slower will quiet the
airplane a little, give better acceleration and climb performance.
The Jabiru is 80 hp and the Verner 133M is 78 hp. Since the hp rating is
real close, my cruise should be about the same but the rest of the
performance numbers should improve.
I am doing the final little items needed to crank it up for the first time
now. The only thing I have to do tomorrow is drill and install the EGT
probes and attach the exhaust system. Hopefully I will fire it up just
before lunch tomorrow. Over the weekend I will rework the gap seal to fit
and put the wings back on and be ready to do a new weight and balance on
Monday and be ready to fly.
I will post an email with the results of the first few flights with the
Verner engine.

Your reasoning makes good sense. I will be out of town for the next week or
so, going to Colorado on a bowhunting trip, and will be interested in seeing
how things work out with the Verner when I get back. Good luck.
P.S. Looking forward to the cool mountain air and getting a little relief
from this hot humid deep south stuff.

Hi Gang:
Found out recently I have a free Summer next year which
opens things up for a flight back to Alaska. What a way to
celebrate your 65th year!!!
John Williamson and I have been talking about making it a
twosome. So John has to get busy and get the Verner flying
and squared away for the long trek north.
Just got off the phone with Tom Kuffel, Whitefish, MT. He
and his wife Betty, were attendees at the Unplanned Kolb
Flying 2003 last May at Monument Valley, UT.
Anybody else want to tag along?
This will be an unofficial, relaxed, enjoyable, exciting,
flight. Departing around 1 Jul 2004. Probably take a month
or so. The nice thing about it is if you get bored, are too
fast or too slow, you can always bail out and do your own
thing and go your own way. This is a no strings attached
adventure.
Will be nice to have company along for a long flight. Of
course Tom's Prospector flies much faster than John's Kolbra
and my MK III. Sooooooooooo, Tom and Betty can get to the
RON site first, set up our tents, and have a hot supper
ready for us when we come dragging in. hehehe
Plan to do some serious site seeing that I have not had the
opportunity to do on my last two flights North. Included
will be a flight back up to the North Slope, Dead
Horse/Prudhoe Bay, a visit with the Helmericks at Colville
Village, 48 miles NW of Dead Horse, and if we make it that
far, it is only another 185 miles to Barrow, the top of the
world.
We are in the talking stage and next Summer will be here
before we know it.
Anybody else interested?
