Can remember a forum at Oshkosh a few years back discussing the 'pro's and con's'
of in-line water cooled engines V's boxer format (horizontaly opposed) air
cooled engines and apparently the boxer format cylinders under strobe lighting
dance around quite a bit as well, whereas the in-line format was more rigid.
So maybe it's not just the prop 'wiggling' but the prop and engine both moving
to some degree.

| Subject: | rectifying problems maybe |
The red Kolb functioned pretty well yesterday and was able to do a
reasonable aerial shoot without major problems.
Have been holding right rudder...just a bit... to keep it straight at
50 mphi and about...not sure, but about ... 5300 rpms. Decided to try
"feet off" and got slight nose pitch up and what felt like a slight
flutter somewhere behind me. Can't see what's going on back there. Not
reassuring, though. Back to pedals and okay again, but holding a bit to
keep it straight and flutter disappeared. Did it twice. Air calm,
conditions ideal.
The huge rudder trim tab (12" tall and 6 3/4" wide at bottom, bent about
15 or so degrees to right as you face the cockpit, and riveted 22" down
from top on the trailing edge pipe of the rudder), was sloppy, loose.
Drilled the aluminums and the one steel rivet wasn't attached anyway,
intending to find a better way to attach the tab to the round pipe
surface.
A&P said it you are having to hold right rudder, you are already
fighting that trim tab.. "Try flying it without it." Think I read one
of the Kolber gurus said you gottas have em, nature of the beast and all
that.
I'd like some solid information about this idea before I play test pilot
again. Ideas?
Wouldn't mind flying tomorrow. Some haze with the moisture, but good
conditions in a.m.
Still a bit of oil spray on prop, apparently from behind the front carb
on the 532. Just replaced the gaskets at about 95 buck s a whack each
and think I have em tight. Oil appears to be from one of the little
mystery hoses there. Again, open to ideas of getting this thing good to
go. Did replace the muffler gaskets, and didn't put any sealant on them.
Ones I removed that were really leaking looked okay. Wondering if there
is slight warp that may have occurred in past.
Anyway, always grateful for the help and the array of ideas.

Not sure from whom/where I got the recommendation for attaching the fixed trim
tab, (CRS) but I do remember that it was from a respected source.
Mine spans the bottom two ribs in the rudder (not the bottom edge). This puts
the vertical center of the trim tab at about the horiz stab. In the construction
of the rudder, the ribs are bent at the rudder trailing edge into 'L' shape,
then riveted to the TE. The rudder trim tab was made of sufficient size to
be able to rivet it to the ribs a couple of inches forward of the TE and in the
'L' where it connects to the TE. I did not rivet it to the TE. Have attached
a picture of the rudder showing the approximate set up for the trim tab and
where it is riveted. The blue lines are the rudder ribs and the dots show the
rivets. (The picture was actually taken before the trim tab was installed.
I have modified the image to show the approximate setup.)

Would agree with your A&P re: fighting the rudder. Too much trim. Take some of
the angle out.

My guess is that your "little mystery hoses" are overflows from the carb bowls.
Check carb alignment to ensure that they are level particularly if you have
had the carbs off replacing "gaskets".
Just some things to consider. Worth what you paid for it.

John if you put a motor actuator to flap that tab you won't need a prop.

Just tuned in to your message, don't know how far you are into checking for
sure what is on the prop.
Bing's will let fuel overflow from the small vent line if the float is set
to high or if the valve is not sealing completely.
Just out of curiosity have you given the substance the good old taste test?
Sweet or not?
Oil vs coolant.
Just a thought.

Hi David L:
I understand what you are saying, however, the strobe gives a split
second picture of the blade. The IVO prop blade was as crooked as a
snake. The engine and prop were stationary. The prop hub remained in
the same position during every flash. The prop blades danced like a

I am surprised that some of the guys did not pick up on this so here goes.
If you do not have strong return springs on your pedals then you can expect
the rudder to flutter if you remove your feet. In my case, there are no
springs, instead there is a return cable loop. It works well but if you take
your
feet off the pedals you can expect a flutter to start soon.
Also, when Bryan Melborn builds Fireflys he always puts the same tab on the
rudder from the get go. According to him it works every time. When he
recovered my Firefly he puts his standard tab on the rudder and it work perfectly.

Steve and others,
After watching the questions raised and info returned immediately and as
Kolbers get fly home and time to check this forum, I have learned to lay
low until the volley subsides, but already (a bit of creative humor
included) good thinking based on the experts' treatment, personal
successes and trial and error, has been reflected. I'll read a while
longer. Maybe ask for some more specifics. Such as, my being new to
Kolbs, haven't sorted out Bryon or what his standard tab is. Or if it
is suitable to the Mark III. Thanks, all.

That is why my MKIII has a counterbalance on the rudder as well as on
the ailerons. Not just a slight flutter, more like "Your boom tube is
now a sine wave" and the rudder pedals are moving to the stops in both
directions flutter. Some rudder flutter is fairly common for Kolbs, but
mine was absurd. And probably very bad for the airframe...

Hello Big Lar.
For a while I thought you might beat me into the air, but now I have hope again!!
A few thoughts: 1) I have the SPG & it is a bullet proof unit with a BMW rubber
donut, rated for 150hp. It would be a great match for you if only a VW adapter
was offered. the north america dealer told me a guy in CA made a VW adapter
& it was just a flat plate. He could probably get you the guys name. The rotax
e-box might be the best way as it incorporates a starter & that might save
you a lot of weight, but they won't sell you one unless you provice a serial
# of your rotax engine.
2) About wiggles: All inline 3 cyl (2 or 4 stroke) rotate around the axis of the
crank. Nothing will stop it but a counter rotating shaft. All 4 cyl inlines
jump up & down & only a counter rotating shaft stops that. the flat opposed
4 is inherantly cancelled & is the smoothest configuraton. The wiggles from
the inline 3 & 4's are obviously sufficiently delt with in thousands of instances
or they wouldn't be seen in aviation. Everything is a compromise!
3) Please don't give up!!!! You are a hero to many of us.
Progress Report: After coming up with a 42% cg I had to drop back & start afreh.
I moved the engine 12" forward which caused me to weld up a new oilpan & oil
pickup. That's done. Now the engine sat too high so I cut out the engine
mount & backbone which left a bigggg hole to drop the engine (3cyl, Suzuki, 100hp,
turbo, intercooled, distributorless ignition, port injected, 107 lbs torque
at 3600 rpm) into my SlingShot. I bought a tig welder & wish I had done so
years ago. It is so easy & does such a beautiful job & no sparks to fly! After
just messing with the oil pan, I am confident to start on the kolbs structure.
that's not done yet. I keep changing the design & am going in circles.
Its hard to keep it simple, light & strong--- Kolb is a genius at that! I will
prevail.
Looking forward to another visit when you pass this way. -richard swiderski

Just a bit of useful information regarding EIS and capacitance senders.
I bought a new EIS model 2000 for 2 stroke engines when I began the
rebuild on my Firestar. The main reason that I went with the EIS is that
the new pod from TNK is shaped different, longer and more streamlined,
and my analog gages were not going in there like I would have liked.
Plus I had intended to use a 503 motor with dual EGT and CHT senders. My
gages were for only one of each. So for me the cost was worth it. Plus
when I talked with the gal at Grand Rapids Tech she informed me that I
could get a remote to do the changes in the display rather than have to
lean forward or as Ralph said, carry a big stick. So I got a stick grip
with five buttons on it, which I configured to the EIS. Works great!
Then Boyd tells me that he is using his EIS to monitor his fuel. So I
talk to the gal at GRT and she walks me through the set up for the fuel.
Last year my fuel gages had quit reading my fuel levels. I "thought"
that it was the senders that had malfunctioned, so I bought two new ones
@ $95 each. They didn't work at all, so it was going to be the gages
that needed to be replaced this time. I really did not like that set up
because I had to run the fuel lines to a selector valve up to the front
where I could monitor them. That is quite a long run, requiring a facet
fuel pump to make sure that the gas got back up to the motor.
Now the way that it is set up is that both tanks are plumbed together,
with the facet pump next in line then through a "Heffner" gascolater to
a filter then to the pulse pump and the engine. The EIS AUX line reads
the capacitance sender and at full (10gal) shows 56 on my display. 8
gals is 50, 6 is 35, 4 is 20 and 2 gals is 6. I have the alarm set to go
off at 9 which means that I have 3 gal of usable gas. I took the top of
tank pickup tubes out and installed a weighted filter on the ends of the
pickup tubes via some fuel line. This is so that I use all the gas that
I have available. I had previously raised the tubes up off the bottom
just as a precaution to prevent picking up any water or garbage that
might have accumulated on the bottom of the tanks. With the gascolator I
can drain all that out and it will not be a factor.
I did not realize that the EIS would do this when I bought it. Thanks
Boyd! One of the factors that cause me the greatest unease when I fly
here is how much fuel I have. Every place can be hazardous to landing
here, and it is a looooooooooong way to more fuel.
