The surface you are landing on makes a difference as well. Landing on pavement
vs gravel, dirt or grass is a whole different deal. Loose surfaces are more
foregiving than asphalt or concrete runways so you can get away with landing in
more x-wind on them since the wheels can slide and you can straighten up after
touchdown if you get a little sideways on them without getting slung back in
the other direction like what can have happen on pavement.
When I was first learning to fly the Firefly I landed on a gravel taxiway if there
was any significant x-wind and still would in heartbeat if it was really blowing
x-wind.

Congratulations to Henry Voris, who had a successful first solo yesterday in his
Firefly!!! He he recently purchased the Firefly from me. Henry lives on Maui,
HI and has been here in Tucson the last couple weeks taking U/L lessons from
a local BFI. We had an ideal day yesterday for his solo and he got her up,
flew around the valley about 45 minutes and got her down (both from a gravel
taxiway) without bending anything... :) He plans to stay here until the end
of Oct, getting used to flying the Firefly and seeing the local sights before
shipping the plane off to Maui in late Nov. I can't wait to see his photos from
Maui. He's a really good photographer and one heck of a interesting and nice
guy so he'll fit in well here.
Please welcome Henry to the list and give him all the same great support I have
had over the last 5 years!!
Thanks ya'll and CONGRATULATIONS again to Henry!!

I've been flying for many years, and I'm currently part owner of a Cessna
182. I also own a recreational vehicle which I love to travel in, around
the country. But what I would really enjoy, is an airplane that I could
tow on a trailer behind my RV, stopping and flying wherever the scenery
looks interesting. RVs seem to be towing every other kind of recreational
vehicle, these days, so why not an airplane?
Obviously such an aircraft would have to have folding wings, which is why
I've been looking at the Kolb Mark III Xtra. It looks like Kolb aircraft
are designed for folding and trailering, while other folding wing designs
seem to have been included as an afterthought; more for taking up less
space in the hangar. I also see lots of pictures of Kolb aircraft being
towed around on trailers; much more so than other aircraft. Is there a
reason for this?
I also like the fact that the Kolb does not use a wet wing, thus there is
no need to drain the fuel before folding the wings.
Does anyone have any experience with extended trailering of the 701 behind
an RV? If so, I would sure like to talk to you!
If anyone has any suggestions or advice on this topic, I'd sure appreciate
hearing from you. Thanks!

I looked in my manual for the max egt and it says 1200. This is the
first time that I have had an instrument to check my EGT's on both
cylinders, and my front cylinder runs about 1180 but the back one is
hitting 12 40 to 1258 occasionally. I have run it for at least 258 hours
without knowing what the back cylinder is reading. The full throttle has
been adjusted to lower the EGT, but I am on the bottom groove of my
needle jet, and cannot go any richer for the midrange. Does anybody have
a differing max reading? I am sure that a bit of a safety factor has
been built in to that high end of the range. I should add that I have
switched to my silencer again and am running a 152 main jet, and seem to
affect the midrange some with the differing main jets. I have probably
ran this setup for some around 125 hours without killing in the motor so
far, but ignorance is bliss. I can of course bring it within range by
using the enrichner circuit.
I switched back to my silencer because I flew yesterday for 1 hour 3
minutes and burned about 5 gallons of fuel. It is not blubbering it out
of the carb, There is no visible or discernable reason why a 447 is
burning that much fuel. I therefore switched back to the silencer to see
if I still burn that much fuel and to cut down a bit on the noise. With
the warp and the fact that it is closer to the wing it is making a heck
of a racket and I have to wear ear plugs along with my DRE 6000. There
is no discernable loss of power, so I think I will keep it on, but the
egt's now that I know about them is concerning me.
Opinions would be appreciated.

Hi Larry:
Pull a little more pitch in the prop and the egt's will come down full
throttle and probably mid-range as well. I am not current in
tinkering with two strokes, been 16 years, but I believe it will also
pull down egt in mid-range.
Usually, pitching to achieve the redline for max continuous rpm, 6,500
for the rotax two strokes, will put the egt right in the ball park
down near sea level. At your altitude would probably be the same if
the carb is tuned as it was when it left the factory.
Remember, our engine instruments are not precision. Don't know if the
EIS is temperature compensating or not.
Noise. All Kolbs are noisy, no matter two or four stroke. Most of
the noise is generated by the close proximity of the prop blade to the
trailing edge of the wing, plus all the disturbed air it is trying to
live in that is generated by the engine and its components.
I never did care for intake silencers or additional exhaust silencers
on two strokes. Anything that reduces perfermance seems not to agree
with me and my flying machines.
You can probably decrease prop noise by going to a prop extension,
getting the blades away from the trailing edge.
For what it is worth.
john h
mkIII
PS: Many folks get wrapped around the axle trying to get their two
stroke or four stroke to operate in the correct range. The instrument
sending units are probably not nearly as precise as the engines you
are flying. Any way, would rather err on the rich rather than the
lean side.

Kolb Listers,
I discovered one other item that Im offering for sale on the list.
I have a set (100) CCI lexan Vortex Generators.
http://www.vortexgenerator.net/ I bought two sets but only
installed one. The first set went on our Mark III. They are not
very noticeable at all and do a great job.
We sold our other Kolb before we installed the other set so now Ill
offer it for $60 including shipping and the remaining half bottle of
Loctite 401 instant adhesive used for attaching the VGs.
You can e-mail me ( wmtatham@juno.com )

The hangar is getting emptier. A Texas flyer made short work of the

The only thing left is the 13 qts of CPS AV-2 50/50 blend 2-cycle

Is your airplane louder than my mkIII? You flew in it last May.
When I first used my new DRE6000, I had trouble sealing around my odd
shaped head and my glasses. A tiny air leak destroyed any noise
reduction they were trying to make. My set came equipped with temper
foam ear seals. I traded a set of liquid gel ear seals from my David
Clark 10-40 headset. No more air leaks and the DRE6000 worked much,
much better.
Are you getting a good seal? and are you still using the original
temper foam seals?

Understand the heat spike is at 44oo to 4500 rpm. However, you did
not say what it was at WOT and your cruise rpm which is 6000.
After a little more thought and the info you posted in response to
Richard Pike's questions, I wouldn't get too bent out of shape about
it. If it bothers you, then increase or decrease throttle a little to
find more desireable egt.
Again, pullin a tad more pitch will also reduce egt.

I agree with John, 6600 rpm is a little high for WOT level flight, crank in
a tad more pitch and get it down around 6400- 6500 and I'll bet you'll like
the effect on your EGTs across the board.

Now Chris you've confused me. You talk a lot about towing a Kolb and it's
advantages, etc. but then you ask about towing a 701??? Oh well, I have a
MKIII Classic and have towed it all over the place. Dunno how many miles
but its gotta be upwards of 5,000 and virtually no problems except those
that I've caused. The Kolb does real well in it's rolling hangar, which is
an enclosed trailer. Lots of guys tow their Kolbs. Be glad to help in any
way I can. Ask and you'll get it answered.

Gang,
Thanks for all the help. I feel a little like Beauford did. When things
change there is a reason. The only problem is that I am not smart enough to
find it. While I am used to being baffled, I am still not reconciled to the
fact!
I put a 152 jet in it since my last post ( I had a 150). Before and now the
temp at cruise is 1180 to 1150 on the front cylinder and 1180 to 1224 on the
back. I also just got back from flying it for 29 minutes to see what it is
doing and to try to find out why I am burning so much fuel. The temps did
not change with the main jet change, other than the fact that if I used the
enrichner circuit it wanted to shut down the motor. so I will go back to the
150 or preferably the 148 jet, which ever will work. I am going to pitch the
prop up a 1/2 or full degree. I have been hitting 6540 on climb out,
actually less at flat wot. ( I have it set at 71/2 degrees with the
protractor) This time I got the best temps at 5700 to 5800. From the action
of the enrichner circuit I feel that the main jet is too big.
When I got Jack's post I hopped up and went out to check the carb position
and found that it was tilted towards the back already. I am aware that the
manual calls for it to be vertical to the engine. Is it possible that It
would do better up straighter? I tilted it back anyway.
John, I checked my spacer that I had for the IVO and it is a 2 1/2 inch
model. I do not have bolts long enough to mount it. I put new gel seals in
my DRE the day I got it. I don't think it squeezes my head tight enough
though, so I will look to tightening that up. No John it is not as noisy as
either Pfer or John W's Kolbra, but it is a lot nosier than it used to be. I
can live with it though.
Now for fuel, I flew for 29 minutes with 5 gallons in both tanks at 57 to
5800 rpm's with of course a climb out to 500 feet agl on take off. My back
tank is supplying more fuel than the front tank. That leads me to believe
that it is being pressurized by the air flow. That part is different in this
version in that the tanks are exposed at the top since I did not cover up
above them hoping that with the increased air flow to the prop, performance
would be better. In the flight I burned 1.5 gallons in 29 minutes. That is
more like what it should be. Yesterday I flew for 63 minutes and burned 5
gallons. That was with a stock jet needle and a 160 main jet, no silencer.
The jet needle that I am using with the silencer is thinner, therefore a bit
richer. It is the next size up from the stock jet needle. If I were using
stock it would be a lot hotter.
I find all this very confusing. All I did was flip it up on its back, you
suppose its still holding a grudge?

No wonder you are burning so much fuel if you cruise at 6,000. I have my
582 prop pitched so that I climb out at 6,250, max RPM is 6,450, and
cruise at 5,300 solo, 5,600 with a passenger, and it uses under 4 gph
solo, a little over 4 gph with a passenger. And it is a whole lot
quieter at 5,500 than it is at 6,000. Crank some pitch into that prop
and see if you don't like it a lot better.

What rpm's are you running? Max? Cruise? Climbout?

I am running 6600 max, prefer 6000 for cruise, 4400 to 4500 is where
the heat builds up.

cruise at 5,300 solo, 5,600 with a passenger, and it uses under 4 gph
solo, a little over 4 gph with a passenger. And it is a whole lot
quieter at 5,500 than it is at 6,000.

Richard:
5300 solo?
That ain't cruising, that's crawling. ;-)
What is the true airspeed at 5,300 rpm?
My normal cruise with Rotax two strokes was 5,800 rpm, 75% power.
Fuel burn was 3.75 gph in the 447 and 5 to 5.5 gph with the 582. Come
to think of it, I also cruised the Cuyuna at 5,800. Can't remember
what it burned, but probably something like 3 to 3.5 gph.
BTW: Isn't 5,300 rpm just a knotch below where the engine comes up on
the pipe? or am I living in the past again? Maybe all that has
changed since my two stroke days. After all, my last one met its
demise 13 years ago.
Take care,

Larry,
Take a look at your spark plugs to see if you are burning rich or lean.
When you engage the enrichiner (choke) and the engine wants to quit, that would
seem to indicate you are running way rich and the plugs are flooding out. If
that is the case, check that the carb needle circlip is placed below the
plastic spring thingy. Others have on occasion installed this incorectly and it
allows the needle to ride up resulting in excessive richness and fuel burn.

Oops! Sorry. Meant to say Kolb. I've also been looking at a Zenith 701,
since it also has folding wings. Wanted to find out which plane trailers
better, so I asked about trailering the 701 over on the Zenith list. Guess
I still had the 701 on my mind!

Much appreciated, Dave. I definitely get the impression that lots of
pilots tow their Kolbs, but I don't hear too much about trailering a Zenith
701. One of the guys from the Zenith factory admitted to me that the 701's
folding wings are more intended for saving hangar space, rather than
trailering. In fact, he recommended that the 701's wings be completely
removed before trailering. Also, since the 701 has fuel tanks in the
wings, the fuel has to be drained before folding the wings (or removing the
wings). And the 701 uses bolts, rather than clevis pins to secure the
wings, so the Kolb folds a little faster than the 701. And finally, since
the folded Kolb is not nearly as tall as the folded Zenith, the trailer
wouldn't have to be so tall.
Looks like when it comes to towing, the Kolb is the clear winner. And
that's a very important consideration for me. I want a plane that I can
tow behind my RV.
And it looks like the view from the Kolb is unbeatable. Since I'm buying a
plane for sightseeing, that's also very important to me.
I'm still making up my mind between the 701 and the Kolb. So if I
occasionally seem to mention the wrong one, you'll know why!
But I'm definitely leaning toward the Kolb at this point. I've had some
sheet metal experience, which favors the all-metal 701, but it looks like
fabric covering isn't that hard to learn. And I hear it's cheap to repair.
