Subject: | Re: syncro of carbs |
I think the confusion is that we are not used to looking at a CLOSED SYSTEM.
There is no vent to atmosphere and hoses fit tightly into bottles. If vacuum
on one bottle is greater, fluid will flow into that bottle. If carbs are adjusted
equal, fluid flow between bottles will stop. Fluid level does not matter.
Fluid transferring between bottles means carbs are not balanced.

Makes perfect sense. Imbalance of vacuum=movement. Lack of movement=balance. Thanks,
got it.
HOWEVER ~ (Much mental activity going on here... sound of gears grinding...) ~
I am thinking that in order to know that your carbs were in fact perfectly balanced,
you would have to balance the carbs, open the system, reconnect the system,
and run the engine again.
Here is why: even in a closed system, the levels of liquid would still seek to
be even with each other, because if one liquid level was higher, it would want
to siphon until both levels were equal, but it can't. If one bottle was higher,
it would want to siphon into the lower, but because the system is closed, it
cannot level itself. However, gravity is still placing an inherent imbalance
on those liquid levels. That gravity imbalance manifests itself as a pressure
differential, and that is what we are measuring when we balance our carbs.
In our situation, if the levels stabilize at an unequal height during adjustment,
I think it is going to preclude getting a perfect carb balance because now
we have to factor in a pressure differential caused by unequal weights of liquid
in the two bottles. Even in a closed system, that pressure differential still
has to be a factor somewhere.
Let's say you start with both bottles level, liquid levels the same, hook it up
and run the engine. Carbs not balanced, siphon occurs and the bottle with the
highest vacuum begins to fill. You adjust the carbs for balance, and siphon/transfer
stops. But if one bottle is now 1/3 full and the other bottle is 2/3's
full, then there is a weight / pressure imbalance which my carb vacuum settings
have to compensate for. One bottle has a much greater weight of liquid, which
is seeking its own level, but my carb setting is preventing that from happening.
Which implies to me that my carb setting cannot be perfectly balanced if
it is compensating for a weight imbalance / pressure differential.
So if I was doing it, at this point I would shut down the engine, disconnect the
tubing, let the liquid siphon/transfer occur until both bottles have level liquid,
then hook the system up again, run the engine, and if the carbs are in
fact balanced, no transfer would occur, and the liquid levels would stay the same.
Then I could quit worrying about it. [Wink]

Subject: | Fw: Brakes and full enclosure |
Brakes are good for lots of stuff:
-As Herb mentioned, ground handling, especially in high wind. Also nice
to prevent ground looping in high cross wind conditions.
-Back in the mid 1980s, I landed at Ozark, Alabama, Airport. The gas
pump was downhill from the taxiway. Had to get out of the US and FS
(before I got brakes) and walk the aircraft down to the pump.
-They are also handy for run up and mag check.
Plenty cross wind in Ely, NV. Hard to walk from the truck to McDonalds
for a hamburger. ;-)

slow list Chris...
I have installed full enclosures on two Fireflys...I did a gull wing
enclosure on my MkIII..
easy to do...the 1/16 lexan just lays over the nose cone... a 4x4
sheet works...was 35 to 40 bucks here in Tenn.. Lay the paper covered
lexan over the nose cone and rear bow that you have made and do a rough
marking of the size...over sized a bit but to shape ..this makes it easy
to clamp and handle. Once the shape is made then move on to mounting..I
let the Lexan lay over the nose cone by about 1 and one half
inch..enough to allow the rubber seal to clear the front of the cone a
bit... 1/8th inch...will do..
Making the rear bow is not science...just bend it carefully and try
not to go to round such that it is sticking out any further than need
be...Guess your shoulders would dictate the bow size..Oval is
good..toward flat.on the sides.. The top of this bow is braced by
another bow that runs rather horizontal to the cromolly verticals that
attach to the spar carry through..this is attached to the cromolly tubes
with gussets and that tube and rear bow meet and are gusseted to one
another..on the top...
I install a stop screw and decorative washer at about 10 am.. thru the
lexan to the cone..I raise the lexan up to a comfortable entry position
and install that screw...I also note where the lexan is on the rear bow
and install large head rivets from there down to the end of the bow on
that side(left) I install a powder coated white angle aluminum on the
top of the left longeron and fasten it in maybe three or 4 places then
fasten it to the lexan from nose to bow I attach it to the bottom of the
rear bow but not to the nose cone....I use the decorative dimpled washer
and flush screws there...then once the lexan is down on the right
side...I mark the paper covering and install white angle aluminum there
also..from nose cone to bow..At the nose end I install a tapered screw
of my own making I flatten or grind it flat and attach it to the
aluminum angle ..I drill a hole in the nose cone bracket such that the
tapered screw fits snugly and holds a good wrap around the nose cone..
before you do this install the rubber seal on this end of the
lexan..some hold it with silicone but I use the 3m black weather
seal...Trial fit the rubber seal and tape the lexan on both sides so
that the rubber goo that squeezes out of the seal does not get on the
lexan beyond where it is intended to go...I use good auto paint tape
here...Then install the tapered screw on the angle that is attached
same as the angle on the left side...now...make a sliding latch that is
captured by the aluminum bow that the rear of the lexan lays on...you
can make some sort of prop...to hold the lexan open for entry/exit ...i
tended to use my head... naturally the right side angle is only attached
to the lexan... and it is good to make a stop on the sliding latch such
that is cannot rise up the bow..though the slip stream should be fine
for that...
Clear as mud? Herb
my cost is usually the price of the lexan...maybe total of 50 bucks..
oops...brakes...I use mountain bike brakes..they come from the salvage
yard on bicycles ...front only usually...meaning that one side mounts
with cable forward and the other side rearword..
I turn aluminum spindles to mate the disk to the rim..I have good
luck using the two piece spun rims...they are true...
The hard part is mounting the caliper...here you need to make an
aluminum plate that slides over the axle and mounts to the 4 holes in
the large washer that is part of the kolb axle..from here it is a matter
of a spacer,trial and error, to get the disk pad/caliper/disk distance
correct. a cromolly tube that slips over the axle and sets the distance
from disk/rim to caliper... is the spacer..
In the pics..notice that I left too much lexan on the left side..need
only be 1/4 inch below the longeron..

where there was a lot of aircraft taking off and landing never had any
trouble as long as I stayed alert and thought ahead! I read most kolb
concerned emails on the list and see that most builders go out of there
way and risk too much weight to install brakes . Are they necessary ?On
a FIREFLY?
My next question I prefer a full enclosure and I called Kolb and
asked for a price on the full enclosure without the lexan as I have a
local supplier for that the price was $308 ? What is included ?
Looking at the Plans all I can see is about $30 dollars worth of
aluminum and a few bolts I think I can build it myself . Is there
somthing I am missing ? Just hoping for some input Chris

"""Right at the end of the video the man said something that I think is not
accurate;
he said it makes no difference what the comparative level of the liquid is
in the 2 bottles, as long as it is not rising or falling.,.............."""
Boyds response. "I think the statement is ok. I can live with it"
Because both bottles are tied together they will seak the same level
provided the vacuum is the same. But it may take some time to level out.
( the leveling function would be a siphoning action). If the levels
are changing rapidly there would be a big difference in vacuum levels. If
the levels are changing slowly that would indicate a small difference in
vacuum levels... If the levels are the same or different but do not appear
to be changing, that would indicate almost exactly the same vacuum
levels... One to two inches of water column difference is very tiny...
After watching this video , you tube suggested another where they used 4
pressure / vacuums gages. the presenter seemed OK at a one pound
difference between carbs... A one pound difference would be a 27 inch
water column difference...
Setting this will provide a smoother idling engine with less backlash in
the propeller reduction gears . with the levels the same, each piston will
be creating the same power. (Provided all else is equal)
It is probably just as important that the carbs open at the same level at
cruise power setting. As was discussed at length in other videos I watched.
I think you could chase your tail making it perfect,,,,, then tomorrow
with a change in barometric pressure, or , a change in the outside air
temperature, or some other variable factor,,, you could do it all over
again

Subject: | More HKS Engine Interference Questions |
Hi again Kolb List, I spent several hours out at the hangar trying to figure out
the correct mounting for the HKS engine that will clear the wing parts when
folded. I need an answer to another question from those who have been downt his
road with the HKS.
What is the acceptable height of the propeller shaft / thrust line on the Firestar,
as measured from the Kolb rubber engine mounts, or from the main engine mount
support tube on top of the fuselage ?
I was and I am in 100% agreement with the many Kolb List experienced pilots who
have said that too high of a thrust line causes problems.The lower the thrust
line, the better the airplane flies.
However, even with the aileron torque tubes rotated or moved out of the way during
wing folding, the bottom of the HKS exhaust pipe just under the exhaust port
is in contact with the inboard "root rib" area of the trailing edge.
Moving the engine FORWARD on the fuselage will solve this problem, but the propeller
will hit the bottom of the steel cage just above the tailboom tube.
Raising the engine several inches will also solve this interference problem, but
then the thrust line may become high enough to change how the airplane flies.
So the question is... how high can the propeller thrust line be on a Kolb Firestar
2 without causing a change in the aircraft handling?

As to your question about how high- I cannot tell you that as I have not
gone there as of yet. I can tell you that my wings will fold by turning the
ailerons in the extended position when it is folded. I can also tell you
that with the engine set the way that it is, when I give it full throttle
the plane climbs without my influence on the stick. So apparently I have
not raised it too high yet.
I once rode in a Mark three that when full throttle was applied the plane
dived without stick up pressure. It scared me!

Just a thought.
Move the engine forward to clear the exhaust. Use a spacer to move the prop backward
enough to clear the rear spar.

Stuart thanks for the reminder.
I forgot a few things. As far as I can tell the engine plate is a standard
one from Kolb. I know that it fits a 503 as well as the HKS. The HKS bolts
are 3 1/4 inches forward on the plate, and seem to be centered equally. I
also got a prop extension from Rick that I like a lot. It is 2 1/2 inches
long.

Subject: | Re: More HKS Engine Interference Questions |
Thank you Larry and Kolb List'ers for the responses.
Larry I did remember you told me you had two inch spacers... however I measured
my installation, and going from the one inch spacers (what I have now) to two
inch spacers (what you have) will still not raise the exhaust pipe UPWARD enough
to clear the trailing edge tube of the wing (even with the aileron swung out
of the way).
The problem is only with the wings folded back for storage or trailering. There's
PLENTY of clearance in flying configuration.
Because of the offset between right and left cylinders on an opposed engine, the
left wing is a bigger interference problem than the right wing.
The engine might have to go forward, and that means I will have to use a prop extension
so the prop doesn't hit the rear of the steel cage. Does anyone know
whether I can use a 3 or 4 inch extension on the HKS without putting too much
load on the crankshaft or main bearings?
Thank you guys for helping solve this problem. Does any one know whether David
Bigelow (HKS powered Firestar 2 in Hawaii) is still flying or participating in
this group?

So the question is... how high can the propeller thrust line
be on a Kolb Firestar 2 without causing a change in the
aircraft handling?
Bill Berle
--------
Since I am one of the few that have an
HKS, I guess that I will have to tell you again that I have
mine with 2 inch risers, swing a 66 inch prop giving me
about 3/4 of an inch clearance.
As to your question about how high- I cannot tell
you that as I have not gone there as of yet. I can tell you
that my wings will fold by turning the ailerons in the
extended position when it is folded. I can also tell you
that with the engine set the way that it is, when I give it
full throttle the plane climbs without my influence on the
stick. So apparently I have not raised it too high
yet.
I once rode in a Mark three that when full
throttle was applied the plane dived without stick up
pressure. It scared me!Larry

Subject: | Re: More HKS Engine Interference Questions |
I may have found the problem why Larry's installation is different than mine !
The hotos he was kind enough tos end show exhaust pipes that are NOT separated
just past the exhaust port. Mine have a break, with a "Swivel joint" and springs,
just 2 inches outside of the exhaust port. These undoubtedly take up more
room, and make the exhaust pipe hang down a couple of inches lower under the engine,
than Larry's "solid, no swivel/spring joint" system.
So in order to have the thrust line in the best possible position (so I can get
the great Kolb handling that I've been hearing about), I may wind up having to
make up a new exhaust system that takes up less space, or routes the exhaust
pipes a different direction, etc..

As to your question about how high- I cannot tell
you that as I have not gone there as of yet. I can tell you
that my wings will fold by turning the ailerons in the
extended position when it is folded. I can also tell you
that with the engine set the way that it is, when I give it
full throttle the plane climbs without my influence on the
stick. So apparently I have not raised it too high
yet.
I once rode in a Mark three that when full
throttle was applied the plane dived without stick up
pressure. It scared me!Larry
