Like I said Ferg - get a local machinist to knock out a couple of ends for
your throttle box and swage them on to whatever inner cable you have chosen-
stronger twisted wire or solid. Cost to me in uk 30 GBP.

Ferg,
Use AN111-3 Cable Bushings from ACS (p 137). They fit over the -3 bolt. I
used a cable end fittings from the local hardware store similiar to Lockwood
BR06 (p 172). Wrapped the solid wire around the bushing and secured with
the cable end fitting. Also gooped with Aroldite. Works great!

Starting to get an uneasy fealing here - were just about to cut holes to
fit the avelec guage. Does anyone out there have a good thing to say
about it other than Bob Harrison (i'm assuming thats what you were
referring to as your capacitance guage Bob).

All this discussion about fuel senders/gauges etc and it all seems too
difficult and fraught with danger.
There must, I feel be a way of installing a decent gauge with a tank sender
which does not involve making a hole on the tank top within the confines of
the headrest.
Surely it is not necessary to enter the tank vertically? I think I shall
wait until something much simpler and easier to install before going for the
mod. Are there any more ideas out there?

I fitted the Europa sender with the top on and it worked okay following the
instructions. It only took an hour or two.

> I shall wait until something much simpler and easier to install
If one wishes to avoid the vagaries of capacitance senders, I found that
a mechanical sender works well enough. I drew the outline of half the
tank (looking from the front) on paper, marking gallons off as tested.
Then it was a simple matter of setting it up against this template to be
more accurate a low levels of fuel. I found also that bending the float
arm into an elliptical shape took out some of nonlinearity of the tank.
It's not then real accurate at around 3/4 tank up, but that doesn't
really matter.
I found also that rather than the junk the aircraft catalogs sell for
"experimentals," a boat supply place near me had a quality universal,
rheostat-type, float sender and better looking choices of panel gauge.
As long an experimenter with electronics, how we deal with tiny levels
of capacitance (a handful of picofarads) and design something stable and
accurate (beyond the varying fuel dielectrics), I will pose as
theoretically achievable at least.
My newish Toyota is the one built from many Lexus components, and just
about everything is controlled by "the computer." However, one input is
from a simple float and rheostat, latter inside the fancy fuel pump in
the tank. Its digital display of "miles remaining" was found to
remarkably accurate even down under like 20 miles, long after its stern
warnings.
I even fiddled with it to see what a microcontroller would need to do to
present a similar display. However, between tank sloshing and
"hysteresis" of the rheostat wiper there's issues, but which should be
fixable with program code. However, the design of the steam gauge makes
this all moot. It would be nice to feed in engine RPM, plus airspeed
from my uEncoder instrument, and present a choice of digital display
info. In addition to making it very accurate, we could have fuel flow,
(rough) distance, time, or gallons remaining. All from a $20 "boat"
rheostat, and a "step through" display button on the control stick, as
per Toyota on my steering wheel. A reasonable goal too for an actual
aircraft to mimic a mere $25K vehicle made by people actually earning
[huge] profits!

Fred F.

picturesGuys,
Please find enclosed a picture of the aft springhinges of the muffler bending upwards
allowing the exhaust to leak enough exhaust fumes to make my CO warner
go wild in the cockpit.
During an inspection of the engine it was noted that the LH backside spring attachment
of the exhaust to the pipe was bent upwards, allowing engine fumes to
pass and trigger the alert.
Please find enclosed a pictures of my exhaust system, showing the difference between
the forward and aft springhinges.
Part total time is 42 hours.
Andy Drapers reports he has never seen anything like this before, anyone of you
perhaps did !?
Best Regards,
Sven den Boer

Hi! Patrick
Simple, you get a bendable probe!
I originally didn't wish to invade the tank and chose Tony Krzyzewski's
Head pressure sensor system which I found to be very accurate,
ultimately I have to admit it got the better of me because a)I'm not a
computer buff and b) I found the device to be extremely fragile due to
being extremely small and so difficult to clamp into the fuel circuit
with the necessary piping at the very lowest point of your fuel system.
If you set out with a plan to overcome "plugging " the sensor and it's
connecting wires into a "tee" connection on the sight gauge line with
the circuit board within say 4" of a suitable box containing the printed
circuit in the belly of the a/c it can be highly recommended.
Unfortunately mine had a malfunction due to a tiny transformer packing
up which meant re-calibrating the replacement by computer. Not a big
deal once you understand Tony's instructions in computer jargon.
My own fault I made a bad connection and with about 23 gallons of Mogas
in the tanks in my garage which is attached to my house it sprang a
serious leak with the computer live under the a/c in the middle of the
calibration.
It was obvious that I needed to abandon and isolate the computer rip out
the sensor and plug the pipework pretty damn quick and ventilate the
garage soonest!
Anyway Having had the bad experience of the finger filters getting wipe
cloth fibres in and needing a forced landing I felt it was imperative to
be able to make "in tank inspections and wipe outs) so I now have a
WESTACH 395-5S-1B-5 0-5v DC Output sender (24" shortened to suit
bendable probe between the head rests as per PFA Mod No. 10602) This
unit works on Voltage variation and I have it connected to a 1.25"
diameter UMA Fuel Quantity Gauge 18-110-1C1 0-5v Capacitive Indicator.
Simple to calibrate the system once you have understood the necessary
power supply requirements.
The calibration was simple needing two "pots" adjusting full and empty.
Except in my case I have arranged my own fuel contents scale around the
instrument and put my own marks of gallons of fuel left.
Pretty sure both items came from Aircraft Spruce and the UK dealer gave
me a lot of good service identifying the 1.25" diameter gauge since my
panel was needing a small instrument.
As I explained having calibrated with Mogas it under reads (the safe
side) when filled with 100LL.

I don't know what it is about your posting, but I think I have been "moved" to
reply to you more that any one else.
This fuel gauge thing is a thing with many answers. You hit my button by asking
if anyone had another way of doing it. Of course , There is always at least
two ways to do anything. Both way will work.
I have some good pictures on my EuropaOwners page showing what I did.
I used a WesTeck gauge for Aircraft Spruce. It is mounted in a standpipe / sight
gauge. It has worked flawless. I did not thing that the rotary molded tank need
a big old hole in it and so I figured out another way. Actually the idea
came to me while reading the WesTeck instruction. (so I am just a copier, it works!)
My sight gauge is behind the right seat where it is viewable while filling
the tank. ( XS )
My 2 cents worth, and remember "I am a armature builder and this is an EXPERIMENTAL
airplane" :)

When this happens in flight, you will hear or feel a slight "popping" noise, Maybe
a small burp in the otherwise smooth running Rotax. It is a Back Fire !
It is caused by the introduction of additional air into the muffler (silencer)
and I know, I have the T shirt.
The problem is with the exhaust system, I recommend you "bight the bullet" and
order an all new exhaust system for Europa. I did and it was made different, better,
and works. The old company had some exhaust systems that where not built
well. Just bad luck for me and Terry too, I am guessing.

I have one at the hanger. I have not seen it built into any ones cowling. I don't
think it is the best answer to the cooling problems.
Again, I took another solution and my web pictures show what I did. I have flown
Wile E Coyote in tempters over 100F on the ground and taxied to the end of a
8,000 ft runway with the engine temps not exceeding 110 C . (it was so hot
in the cockpit that the Dynon showed a thermal over temp error) Your guys in
the UK just ignore me, but the US guys really should thing of a better way to
get air to the "radiators" (heat exchangers) It can be done, I did it !
