Why do you want to remove the trim screw Lloyd? Although there may be
others, I can only recall one failure that caused any sort of problem.

I have only flown the electric on a Model 5 and 6. I like it fine. No real problem
in the pattern. It could use a little more up trim for use with flaps.
It is very sensitive at cruise speed but that could be altered with Matt Dralle's
Governor. If you decide to go with the manual I would be interested in buying
you linear actuator.

All,
I am reworking a Model 5 that originally had the Electric Elevator Trim
Screw. I was intending on changing it to the trim tabs on the elevator and
replacing the Electric ElevatorTrim Screw with the hard link similar to the
retro kit that Skyster was offering. I was recently challenged on that
thought and was wondering what those of you out there flying either the
adjustable horizontal stab, the elevator trim tabs or both feel about the
subject? Which do you like and why?
Thanks,

Thanks Alan, - I have been watching an incipient kink on the other side of
the radiator. I should be more concerned about the suction side of the
pump. The molded hose is a great suggestion. The size of the hole in the
cap of the overflow tank doesn't make sense to me, but it is the stock cap.
Thanks Cliff, - The air bubble seems to fit all the data. I do have a
heater core in the cabin - it was used last winter and this fall. (?) But
we had been doing some extreme slips.
Thanks Sid, - I plan to spend some more time with that website.
Thanks John, - I think I have the overflow tank in the correct place, and
will investigate the hole in the cap.
This list is great!
Randy

Randy,
Most likely had an air bubble in the system... another thing to
check is
the location of the Overflow bottle.. should be lower then the expansion
tank. Check the hole in the cap as well.. I believe there was a service
bulletin on that issue.
Have a Safe New Year !!

Returning home after a ride, we had just touched down and I noticed some
splashes on the windshield. (This is not good!) Since the temperatures
were all still good, I taxied on over to the hangar and my friend helped me
pull the cowl off.
By this time, we had identified the splashes as anti-freeze. I was
expecting to see some hose connection leaking, but all fittings were fine,
but the cowl above the overflow container was wet with Dexron. All the
fittings were dry. As we watched, the engine cooled and started sucking the
coolant back into the engine. I added between 32 and 39 oz. of 50/50 before
it all quit sucking back into the engine. This took several hours. This
still left the level in the overflow container near the minimum level.
My friend says that I just had too much fluid in the overflow container and
it flowed out as the engine warmed up. I don't buy this because; 1) I
haven't added anti-freeze over the whole 87.2 hours of flying prior to this
happening. 2) If this was just normal expansion, I would not have had to
add any additional coolant as the engine cooled. 3) I don't think it would
have put coolant all over the top cowl above the overflow container -
Although the air flow in the cowl may splash it around a good bit.
Anyway, I feel that somewhere (one head?) something was hot enough to boil
the coolant and that is what blew stuff out the top of the overflow. My
guess is that the flow to one head wasn't up to snuff and that caused the
problem. I have taken the hoses off the bottom of all the heads and blown
air down backwards through the head and can't detect any restriction in any
of the heads. I would feel much better if I could find a reason for this
blooping of coolant.
I should mention that I have a Grand Rapids EIS that tracks the head temps
on two heads - neither those nor the oil temp was too high. About 2.8 hours
of flying time before this flight, I had covered about 1/3rd of the radiator
surface to try to raise temps during winter flying. After doing this, I
climbed to 10,000 ft to watch temps and they were fine as they were for more
than 2 hours before this last flight. I don't think that covering part of
the radiator was a major cause, but of course it could have aggravated the
situation.
Any advice would be appreciated.
Lesson Learned
I was really worried for some time because as the engine was cooling and I
was adding 50/50 coolant, I decided to check the oil level. I was surprised
to see it near the top of the tank and decided that I had found where all
the coolant that I was adding was going. But later found NO coolant in the
oil and the oil level was Normal! (My panic was unjustified!)
Lesson? Check your levels when the engine is hot, so you will know what to
expect. I wish that I knew what the level in the over flow container should
be when the engine is hot.
Thanks for listening and tell me what I may be missing.

Our trim brushes wore out at 60 hours but found a place in Conroe, TX who
replaced for $16. They are sensitive at cruise and not quite adequate for full
flaps but are all around O.K. We think we would prefer mechanical though never
tried them for comparison.

How cold does it get where you are? How long had the plane been sitting?
I had my plane in storage last year in an unheated hanger. I noticed some
coolant was leaking from the fitting that goes into the cyl head..on more
than one cylinder. Not a lot..just a few drops on the floor. Someone
knowledgeable with snowmobiles told me that is common. A few weeks back I
went out and noticed the same thing. I ran the engine up and kept a close
eye on it. Once it came up to temp it seemed fine. When I put it way
there was no sign of a leak. Went back a few days later when it was very
cold and again noticed some coolant in the same spot.
Sounds like you had a lot more than a few drops showing..so probably not
the same thing..but thought it was worth mentioning.
Anyone else notice this type of thing with the 912 series of engines when
they cold soak for awhile?

Try going to the BD-5 website (.http://www.bd5.com/bd5.htm) The Hirth has
the longest record on there and some of the original BD-5 builders and dealers
and original test pilots are active on it. There has been a lot of letters
on it so look into the old files/records first. They get tired of answering
the same old questions for people who haven't done their homework. I personally
know only what I have heard. The BD-5's have used the Hirth only in the
pusher configuration, and with long torque tubes. There have been a couple of
BD-5s with tractor engines but don't think those used Hirths.

Let's see if I can ask this question without looking as stupid as I feel. I
am trying to purchase NPT and AN fittings to install a behind the seat header
tank in my model 2. One of the guys provided me with a used tank without fittings
and I am trying to order what I need. I went into the local auto parts store
and the guy matched a fitting with one of the holes and called it a 3/8" fitting.
I can see with my eyes that the hole is bigger than a half inch, but didn't
question him about it. (I bought some fittings from him that fit, but they
are brass and I would rather switch to aluminum). Now, with ruler in hand,
I am measuring that hole to be 5/8", but I see the chart in the Aircraft Spruce
book which sizes the fittings by the "theoretical I.D. of fittings". I could
conceive that they are referring to the inner diameter of the line that the
fitting attaches, but there are pictures in the catalogue that, if to scale, contradict
that notion. If I have made any sense so far, could somebody give me
a clue about how to identify the sizes I need to fit the Skystar header tank.
Also, I see that the Skystar instructions call for rubber wing tank feed lines
all the way to the header tank. I was thinking that aluminum would be superior
for reasons of weight and durability, am I correct about that? I would,
of course, have to use rubber for the (approximate) first foot out of the wing
tanks to allow the wings to fold.

Jeffery,
If you bought 5/8 fittings and they fit, use those dimensions for the AN
fittings - 10D as the part suffix.
The actual fitting - the threaded part- is much larger than the fractional
designation. I don't know how it works, but that is the way it does. It
might have to do with the inner diameter of the tubing or pipe. I am sure
some plumbing guru will make us all a little bit smarter on that part.

Thanks Paul, I had a feeling you would know someone with a similar
situation. I should start the mounting process in the next few weeks. I'll
post pictures and progress and hopefully have a good list of reference
material when the job is complete.

Jeffrey,
Go with the aluminum tubing except for the area, except for the first foot out
of the wing tanks to allow the wings to fold. That's what I did and it has worked
very well.

I have a pan under my Kitfox. The water pump leaks a small puddle when it
gets cold. When I run up the engine and the seals heat up, no more leak.
After a day or two in cold weather, same thing. It has been like that since
I got the plane running in 2000.

Lowell,
Correct me if I'm wrong, but isn't there some concern with getting
the right angles? I believe any brass compression fittings you'd get at the
local auto parts or hardware store are 45 degree flares. And I believe that
AN fittings are 37 degree flares. Aren't the two incompatible? And don't
you have to make sure you have the flare tool that matches the fitting? (I
realize this doesn't apply to pipe fittings.)
PS I also did 1' of flex and the rest aluminum. I think it's a much neater
way to go, and was surprisingly easy to do. (I used 3/8" for both tank
feeds, and 1/4" for the vent.) My wings fold without having to fiddle with
the fuel lines.

Hi folks,
I have been trying to access the Sportflight photo index site for a few
days and could not log on. This seems to now be OK, however, I don't see
any recent entries on the list. The date of the latest entry that I can
see is 22 Apr 03. I have been trying to get a look at the photos that
Graeme Toft posted of his Kitfox and his tanks, but I don't see them
anywhere.
Can anyone advise me as to what the situation is please?

I had this same symptom. Mine came from turning the elbows in the flanges to
align them for connection to the spyder tank. The solution was to remove the
flanges, heat the fitting to loosen the locktite, apply new locktite. The thread
sealing locktite will actually start to set up so quickly that you have to
have the elbow angle set correctly when you stop tightening the fitting. There
is no time to set it in place and then adjust.

How cold does it get where you are? How long had the plane been sitting?
I had my plane in storage last year in an unheated hanger. I noticed some
coolant was leaking from the fitting that goes into the cyl head..on more
than one cylinder. Not a lot..just a few drops on the floor. Someone
knowledgeable with snowmobiles told me that is common. A few weeks back I
went out and noticed the same thing. I ran the engine up and kept a close
eye on it. Once it came up to temp it seemed fine. When I put it way
there was no sign of a leak. Went back a few days later when it was very
cold and again noticed some coolant in the same spot.
Sounds like you had a lot more than a few drops showing..so probably not
the same thing..but thought it was worth mentioning.
Anyone else notice this type of thing with the 912 series of engines when
they cold soak for awhile?

Returning home after a ride, we had just touched down and I noticed some
splashes on the windshield. (This is not good!) Since the temperatures
were all still good, I taxied on over to the hangar and my friend helped
me
pull the cowl off.
By this time, we had identified the splashes as anti-freeze. I was
expecting to see some hose connection leaking, but all fittings were fine,
but the cowl above the overflow container was wet with Dexron. All the
fittings were dry. As we watched, the engine cooled and started sucking
the
coolant back into the engine. I added between 32 and 39 oz. of 50/50
before
it all quit sucking back into the engine. This took several hours. This
still left the level in the overflow container near the minimum level.
My friend says that I just had too much fluid in the overflow container
and
it flowed out as the engine warmed up. I don't buy this because; 1) I
haven't added anti-freeze over the whole 87.2 hours of flying prior to
this
happening. 2) If this was just normal expansion, I would not have had to
add any additional coolant as the engine cooled. 3) I don't think it
would
have put coolant all over the top cowl above the overflow container -
Although the air flow in the cowl may splash it around a good bit.
Anyway, I feel that somewhere (one head?) something was hot enough to boil
the coolant and that is what blew stuff out the top of the overflow. My
guess is that the flow to one head wasn't up to snuff and that caused the
problem. I have taken the hoses off the bottom of all the heads and
blown
air down backwards through the head and can't detect any restriction in
any
of the heads. I would feel much better if I could find a reason for this
blooping of coolant.
I should mention that I have a Grand Rapids EIS that tracks the head temps
on two heads - neither those nor the oil temp was too high. About 2.8
hours
of flying time before this flight, I had covered about 1/3rd of the
radiator
surface to try to raise temps during winter flying. After doing this, I
climbed to 10,000 ft to watch temps and they were fine as they were for
more
than 2 hours before this last flight. I don't think that covering part of
the radiator was a major cause, but of course it could have aggravated the
situation.
Any advice would be appreciated.
Lesson Learned
I was really worried for some time because as the engine was cooling and I
was adding 50/50 coolant, I decided to check the oil level. I was
surprised
to see it near the top of the tank and decided that I had found where all
the coolant that I was adding was going. But later found NO coolant in
the
oil and the oil level was Normal! (My panic was unjustified!)
Lesson? Check your levels when the engine is hot, so you will know what
to
expect. I wish that I knew what the level in the over flow container
should
be when the engine is hot.
Thanks for listening and tell me what I may be missing.
