Thanks for whatever info you can send. Scott O. refers to "nice looking

I'm also considering making the trim tab adjustable with possibly a cable
like Ellery suggested.
Thanks, MIke Welch MkIII (I'll go look at the Kolb list photo site,

I am also going to add electric trim to my Kolb MK-III Xtra. As shown in the
accident report you need to be careful, but there is no reason not to do it.
Many experimental / Ultralight airplanes have "Real" trim tabs, I like this a
lot better than the spring adjustment, as almost all certified aircraft prove,
this is the better way to trim an airplane. On a kolb it also gives you the
ability to trim down and it also gives a back up to broken elevator cables, attachments
etc.
Number one, I will be adding counterweights to my elevators when I add the trim
tab, similar to the ones on the ailerons to eliminate the possibility of flutter.
Stock, the elevator cables act as the counterbalance for the elevator and
keep it from fluttering, but this may not be enough with the added weight of
a trim tab and actuator.
Having a trim tab come free in flight can be disastrous, and induce flutter, it
has happened on certified airplanes plenty of times. There is a purpose built
electric trim actuator for experimental aircraft made by Ray Allen company,
I have flown with it on another experimental similar to the Kolb ( Skyboy ) with
these electric trim on both the rudder and elevator and its WONDERFUL !!!
Its just so nice to do patterns, and just move the hat switch for trim in both
axis and fly hands off whenever you like, like a real airplane !
Given the critical nature of trim tabs, and the possibility of disastrous results,
I would highly recommend using trim tabs that are designed for aircraft.
They are expensive, but not unreasonable. You can look at them at the link below.

Mike , I had a firestar KXP with a trim tab sold to me for around 100 dollars by
Rans it was an alum formed tab which I cut down from 24x 4 inches to about b14x4inches
and it was adjusted by cable with a wheel about 6 inches in diameter mounted iin
the cockpit , mine was on the cockpit frame just ahead of the throttle and was
adjusted like the trim on my Dads 1959 Cessna 172 , Roll it forward the nose
went down , Roll it backward the nose comes up , and I was taking alot of Aeriel
Photos and I could set the trim at any throttle setting to fly hands off
, it worked for me for about 500 hrs . Hope this info is helpful , I don't know
if Rans still offers this but the installation and the use of it was an easy
lesson in aircraft construction. Chris

Back in the late 60-early 70's aircraft avionics were being stolen. None were
recovered until someone realized that the thieves were taking one radio out and
putting it into another aircraft with the same make radio. Then they stole
the radio from the second aircraft. Tough to trace when you are looking for the
wrong serial number.
For years there was a Mitsubshi twin turbo sitting at PA airport-- property of
US Gov. Yours to buy cheap--if you could get the residual white powder out of
it!! Fast aircraft-- but easy to get behind of with a result of pilot getting
bitten hard.

A trim tab mounted to a fixed surface needs to be much larger. When you
put the tab on the elevator, the tab moves the elevator, and the elevator
does the work of trimming the plane, so the tab is relatively small. When
the tab is mounted to a fixed surface (or separately mounted like the early
Taylorcrafts and the Smith Miniplane), the tab has to do all the work
directly and thus must be much larger.

Mike W:
It would be interesting to know how many successful hours of flight have
been put on the MKIII design since it was first produced in late 1991. For
that matter, it would also be interesting to know how many Kolbs have been
built, how many were flown successfully, and how many are being flown
successfully now, and for how long.
My mkIII is serial number M3-011. It was the first complete cage Brother
Jim welded up when we were staying with Homer and Clara Kolb last of 1990
and early part of 1991. I personally inspected the first 40 or 50 MKIII
fuselages that came off the line, was part of my daily chores during the
time we spent building my MKIII during the evening hours.
I can assure you the pitch trim system of the MKIII is more than adequate
and safe. If it wasn't, I would not be flying my MKIIII with it, and you
would be hearing the screaming and moaning of those unhappy souls who were
having problems with it.
I am continually amazed at people who are redesigning their Kolb aircraft
when they have little or no time flying it of any other Kolb. I never
changed a thing on any of the three Kolb airplanes I built before I had
flown and gained good solid experience in them, enough experience to know
what was needed and how to go about accomplishing the task that was
required.
One point on adding "stuff" to the trailing edge of the elevators. The Kolb
elevator is hinged on the leading edge and not at all balanced. Why they do
not have a tendency to flutter, I do not know. However, in the case of the
fatality I referenced, he had added more weight to the trailing edge which
probably got him into trouble with flutter before the trim tab seperated.
The original Twinstar used this elevator trim system. It was changed to the
present system used on the MKIII because it was proven to be a better
design.
Take care,

Hey,
I think the best trim is to just attach it to the "STICK"
Alot of guys have rigged Tension lines / bungies....to the stick
and a little wheel...
I "WAS" going to do it that way..... But my Firestar needs
"NO TRIM".....Mine flys perfect....I was shocked/suprised/Happy
Great little plane....
My next plane that I'm building....."Buttercup"
Has the trim control "on the stick".....couple of springs & lever
.
.
Back to building....Garage is warmed up....
Gotta Fly...

Jim:
I started flying cross country in my Ultrastar two weeks after I got it
flying.
I secured my bag under the fuselage, below the seat, with a bungee type
net with hooks. Map recon was done prior to takeoff. Had to remember
heading, distance and time, check points, etc. Folded up the map and
sat on it. Made a lot of flights from Gantt International Airport,
Alabama, to Tallahassee, Florida, and return in late 1984 and 1985. Was
very exciting to do these flights back then. Landed at airports, vacant
lots next to gas stations, cattle lots, hay fields, and parking lots.
There were a lot of forced and precautionary landings for everything
from plugged fuel filters, loose spark plug caps, cigarette packs going
through the prop, along with muffler bolts and washers. Once did a
forced landing on the foot ball field at Sebring Highschool, Sebring,
Florida. Right after I landed and shut down, I heard the bell ring for
recess. I was soon covered up by curious high school students. Bell
rang again, they went back to class, and I took off for Miami. The
landing in the football stadium was done without the luxury of brakes.

Hi Mike B:
Interesting post on trim tabs.
"Stock, the elevator cables act as the counterbalance for the elevator and

You will have to explain the above to me a little bit better. I do not
understand how cables counter balance the elevators.
"> I have flown with it on another experimental similar to the Kolb (

I use a fixed rudder trim tab and have no requirement for an adjustable one.
Same was true with my FS and US. Far as I know my MKIII still flies like a
"real" airplane without the luxury of Chinese Hat trim switch. ;-)

| Subject: | Re: newe aka Stolen Radios |
I first heard about the stolen/switched radio scam in '65 when it
first(?) occurred at VNY when i was tied down there. Later i wrote
about it in one of my columns in sometime after '93 in Aviation
Digest. later, in my book Flying Tales...it appeared again in Chapter
3, "Scam Ciy:"
Some years back at a Major West Coast airport there appeared a most
clever radio theft ring. It was a "steal-to-order" caper wherein the
buyer actually put in an order for a certain radio, and waited a few
days for delivery. This in itself was not unknown in the heisting
world=97cars and TVS had long been "pro-stolen." But this scam had a
twist that helped keep it going for all too long, making it almost
unsolvabte. In those days we had just a few radios; Mark 12s and
KX-150s were the popular models, and the ones everyone liked, whether
they owned one or not.
On a sunny weekend day we find a kindly "father" walking about the
tie downs with a little boy, ostensibly his son. Quality time. Father
asks son if he'd like to be held up to look in the cabin. You betcha,
dad. Both feast their eyes on the instrumentation, with old dad
glomming the radios. As in computer programming: Repeat, Repeat.
Later: a customer stops in a nearby bar and asks the friendly
landlord whether he has any Hudepohl, or another odd-sounding beer.
"Only by the case, and takes a week for special orders. Twenty bucks
deposit." Customer returns in a week. Barkeep gets a folded twenty,
with several more inside. Says it's in the back room, too busy to
bring it out. Customer says he's parked in back and will just haul it
out that way. Guess what fits in a box the size of a case of beer?
Back to good old dad. It's late at night in an unlit tie down area.
Using one of the famous four keys that unlock all single engine
Cessnas, Dad is in and out in a flash, radio in hand. Does he scoot
home, or to the friendly barkeep with his new-found booty? Nah. He
hits the next plane having an identical radio, one worn about the
same around the channel selector knobs. And what now? He pulls the
second radio, replacing it with the first stolen set.
Owner no.1 Immediately reports his theft to the police, his insurance
carrier, maybe the local radio shop. Nothing is heard of this missing
radio for many months until owner no. 2 has the usual vacuum tube
failure and gets the shop to pull his radio for repair. By this time
there is a large list of stolen radios that has been furnished to
most all shops, and no 2's radio made the hit parade. He's in deep
yogurt for possession of stolen property! Wisely, he had recorded the
serial number of his (original) radio, which helped a bit. but "his"
radio under repair was confiscated, leaving him outa commission. He
then reported his "original" radio, with his recorded SN, as stolen.
Fortunately John Law was finally able to figure out this caper, but
only after many radios were stolen. And there always was a shop that
conveniently didn't check the SNs.

| Subject: | need advice on extra fuel tank hook up |
I've got a Firestar II, and there is plenty of room behind the seat to
add a temp. 5 gal tank for extended trips. I know many Kolb owners use
extra tanks for the same purpose, but I've never seen how they have them
hooked up. I was thinking of teeing off my fuel line and having a shut
off valve in that line so when I'm not using the extra tank I could
easily remove it and shut off the valve. Any suggestions? Also, is
anyone using quick-disconnect fittings on this type of set up in place
of a shut off valve? By the way, I can mount the extra tank so it is at
the same level as my existing 2 tanks, so when connected the fuel levels
would be the same.
Thanks for any advice.

| Subject: | Re: Elevator trim tab information needed |
An electric trim does not cause flutter. A failure that would drive an electric
motor back and fourth is unheard of, they may run away to one stop or the other,
but rapidly back and fourth no. Even on the billion to one chance you could
induce a back and fourth failure in electric trim, the mechanism is not capable
of moving the trim tab anywhere near fast enough to cause flutter. Bottom
line is this is never going to happen. What does cause flutter in a trim tab
is it coming loose from its actuator. A free floating trim tab will induce
flutter very quickly, and has happened many times in both certified and experimental.
Mounting a trim tab on the end of the vertical or horizontal stab is a nothing
short of a horrible idea. First you add stress to the outboard of those surfaces,
the worst place structurally that you possibly can. The tabs would also
be very inefficient, big, and heavy. There is a very good reason that you never
see come crazy setup like this on certified airplanes.
Trim tabs on control surfaces work very well, and when you have an electric actuator
on the stick, it makes a very ergonomic nice to fly airplane. Before adding
trim tabs though, you do need to do your homework and make sure you are
not going to make a mistake that is going to kill you. The electric trim tabs
on the Skyboy that I flew were not in the design, but they were well worth the
effort and made a very nice flying airplane out of it. The work was done
by some airline mechanics that knew what they were doing. I will be copying their
installation on my plane. I have gotten every bit of information on trim
tabs that I can, and am confident that my Kolb would be a much nicer airplane
to fly with them. John H is correct, modifying a known design is risky and
not done correctly could be fatal, so I would recommend that no one try this type
of modification unless they do proper research and have the ability to do
it correctly.

We added a few extra gallons to the local FSII, here is the web page of
how we did it - feel this is a lot safer than a tank sitting in the back
seat -

Subject: Kolb-List: need advice on extra fuel tank hook up
I've got a Firestar II, and there is plenty of room behind the seat to
add a temp. 5 gal tank for extended trips. I know many Kolb owners use
extra tanks for the same purpose, but I've never seen how they have them
hooked up.

Jimmy, for my trip to Texas, (only made it to Deming NM) I rigged an
extra facet fuel pump mounted on Velcro at the right side of my seat. I
then rigged up two extra 5 gal tanks with a screened filter on a flex
tube so that it reached the bottom of the tank. I also put a hose barb
in the cap and routed the vent to the back of the cage. (just in case of
an upside down position when parking) I then ran the two hoses into a
"Nylon Y", routed it to the fuel pump and then out to the front
permanent tank. The tanks were held in place by the passenger seat
belt. I installed a switch close to hand, and could monitor the fuel
level in the filling tank with the EIS. When I took off I ran off the
front tank, (I have the tanks on a selector switch since I could never
get them to draw the same due to the angle that the plane flies) when it
would get down to about two gallons, I would switch on the fuel pump and
fill the tank again. ( If you only have one extra tank, the rate of fill
will pretty closely match the amount that the 503 will burn) I also
used quick connects on both lines so that I could remove either one or
both of the tanks. You will have to make sure that you get the ones that
are closed when disconnected or you will be sucking air. Since I had
twenty gallons of gas, I had a range of about 3.5 hours and still had my
30 min reserve.
By rigging it up this way, I can carry however much gas that I want
for a trip. Or if I have to hoof it to a gas station, then I can take
one or two of the extra tanks by just disconnecting them and unfastening
a seat belt. One thing however, they sell you these quick connects and
the "O" ring is not auto fuel compatible. I just bought some more at
NAPA today that I hope are fuel compatible.
If you need pictures, email me off line and I will forward what ever
you need.
