That is true so the thing to do is to make the seat of the crime as obvious
and uncomfortable as possible.
I once had a lock up shop asnd really could not justify a complete warning
system. I bought a self powered system which consisted of a metal box about
18" cubed. On the top were 2 absolutely brilliant spotlights which flashed
and inside were the batteries and a couple of police klaxons. When there was
any vibration, a heavy footfall or a thump from a door being forced this
thing sprang into action. The noise was indescribable and combined with the
flashing lights was almost guaranteed to frighten the bejasus out of any one
creeping around in the dark.
I realise that a hangar in a fifty acre field is hardly the same but by
applying the principle of noise and light, a klaxon and a flare pistol
shooting a flare skyward might do it. You guys are all good with electrics,
switches and sensors. How about a loudspeaker system playing into the hangar
with noises so loud that it is impossible to work in the hangar. Rock
concerts are like that. For a few bucks and a bit of time you could have a
lot of fun. After all it wouldprobably only have to work once.
Cheers

Nope. Thermal expansion of the aluminum piston relative to the steel sleeve remains
pretty much constant over the life of the two.

| Subject: | Progress on the Mk IIIX |
The latest changes have been made to Ken Holle's Mk IIIX and flown with
mixed results.
The changes were covering the engine mount frame and lowering the engine to
the stock height (nearly, anyway, I have 1/2" spacers on the aft mounts).
To accommodate the latter change a new engine mount plate had to be made to
move the engine back 3/4" so that the "E" gearbox electric starter clears
the rear spar carry through. I've attached .pdf and .dwg files of the new
plate. I also had to provide some clearance for the engine mount tube on the
pull starter flange of the engine. I channeled Paulie on "American Chopper"
and sanded a divot in the flange with my right angle dotco.
Covering the engine mount frame produced the most interesting results. The
climb rate literally doubled even though I swapped my 66" diameter WD prop
for Ken's 70" diameter WD prop. I also had to add almost 3 degrees of pitch
to the prop.
Unfortunately, the lawn dart syndrome persists and the wing still breaks
hard left when doing an approach stall.
Today I have the nose cone off to install some stiffening ribs to eliminate
the deformation I see in flight (the nose cone has taken a set so that it is
caved in even sitting on the ground).
Tomorrow, after I reinstall the nose cone my neighbor is going to fly
formation with me and video the left wing tip to see if the repair done by
the OB is distorting at high angle of attack. I have no other clue as to why
the aircraft breaks left in a stall and requires aggressive recovery
technique to break the stall (most unKolb like).

| Subject: | baggage space comparison |
In my quest to select the best kit for my mission profile, I finally had a
chance to see an Excalibur (tandem high-wing pusher) on gear but not yet
covered. I like the looks, and the specs are comparable to the Kolbra, but
two issues are keeping me from sending that check: The wings are huge (31.5'
x 5') and have 2 struts per side plus jury struts, so removal and
installation will definitely be a 2-person job, and storage will require
a voluminous trailer.
The other issue: the 10gal tank behind the rear seat takes up practically
the entire enclosed space, leaving not even a hat shelf for baggage. I would
have to stiffen the tube-and-fabric "tub" under the seats with thin plywood
to get any significant volume. My question to the group: which of the
current Kolb models provides the most baggage space? Will I have to abandon
my preference for tandem seating? The Excalibur and the Kolbra have roughly
the same "useful load", leaving close to 80lbs of payload with my wife and I
plus 10gal fuel on board. We would like to be able to take a small tent and
2 sleeping bags.
I'll start another thread with an engine related question.

| Subject: | engine choice for Kolbra |
I know the Kolbra will fly on 65 HP (Rotax 582, Hirth 3203), but I want to
eventually put it on floats, and 65HP will not get me off the water with a
passenger. 80HP Jabirus and Rotax 912 are out of my price range (any good
used ones out there?). But the Sonex AeroVee (air cooled, direct-drive VW
conversion) is affordable and economical, plus very inexpensive to overhaul.
Sonex says "161 lbs complete" (starter, alternator, carb, exhaust pipes but
evidently no muffler). Jabiru 2200 comes in at 138 lbs "ramp weight", also
presumably without muffler. I think I can give up 23 lbs of payload to save
approx $6,000 (the AeroVee comes as a kit, but I like to build). Is anyone
flying an AeroVee?

PS: any Kolb flyers / builders around NW Oregon?

| Subject: | Re: engine choice for Kolbra |
Here is my take.
I have a Kolbra with a Jabiru 2200 and it is the only experience I have with the
Kolb line. It works and I get decent performance but I do not get the spectacular
performance numbers I read about from people who have a reduction drive
engine (rotax, HKS or whatever). There is a reason for this and to put it simple,
a geared engine drives a larger prop at a slower rpm and is more efficient
and gives better performance.
That being said the performance is not bad, just not ideal. I like the Jabiru
so far and it gives me a decent payload due to the light weight. I know it will
not perform like a Rotax and I am ok with that.
I could not imagine adding about 50 pounds of engine and 100 pounds of floats and
think I would be happy with it. I do not imagine you would be far from gross
and that is without a passenger. Then if you do not use the reduction on the
vw you will have even worse performance then the direct drive Jabiru. The
reduction adds about another 20 pounds but you can ask as I know there is atleast
one on a kolb on the list.

Kolbers:
After many years Kolb Aircraft has included a few of my significant flights
on their web page:
-1994: http://www.kolbaircraft.com/johnhauck3.htm
-2000 and 2001: http://www.kolbaircraft.com/johnhauck2.htm
Most of you List members are familiar with them, but the new folks may not
be.
My MKIII was designed and fabricated in 1991, to successfully make extremely
long cross country flights. She accomplished everything I have asked her to
do over the last 19 years and 3,100+ flight hours.
All my gear, arctic and desert, goes inside the aircraft in a cargo
compartment, under and behind the seats, and in the nose cone. It is
equipped with a 25 gallon aluminum fuel tank and a Rotax 912uls engine
driving a 71" Warp Drive Prop with tapered, nickle steel edges. It has also
made flights to Alaska with 70" and 72" WD props.
These flights were an attempt to fly the border of the Continental US, and
fly north of Point Barrow, Alaska. Both these objectives were accomplished.
In addition, the MKIII was able to fly to the northernmost Eskimo village in
Canada, Tuktoyaktuk, North West Territory, and all 49 States in North
America. Since 2003, my MKIII has flown across CONUS every year except
2009. That year I could not figure out how to get my wheel chair inside my
Kolb. ;-)
All cross country flights were made strictly solo with no ground support,
even back to the first ones in my Ultrastar in 1984. Ditto for the Firestar
flights.
Kolb Aircraft has been around all these years to support us. Although
downsized considerably over the years, Kolb is still there keeping all us
Kolbers in the air. It is to our advantage to support Kolb Aircraft as much
as possible.
Homer Kolb helped me fulfill my dreams.

I Agree .....It's 'hard to be humble' when you own a Kolb ! It's a little like having a ride on the 'ISS' International Space Station, and then trying not to tell everyone about it .... [Wink] http://www.n2yo.com/
