All too complicated and not necessary. Just borrow an SWR-meter, and see
what it says. Broken wires, shorts, resonance problems, everything shows
up with this simple test.
There are many radio amateurs, find one and he probably loves to look at
the installation of a real airplane.
If there is anything else than the Europa recommended halve wave antenna
in the tail closeout, I would scrap it and arrange such a halve wave
antenna. Contradictory to common believe fed by marketroids, there is
nothing that beats a simple halve wave dipole for this application. No
antenna can have any gain over a dipole without introducing losses in
some area's. It is just like a light bulb, any gain you derive with
reflectors and lenses will introduce dark spot in other directions. A
half wave is close to omnidirectional and only has two small "dark
spots" straight up and straight down. Fortunately if you are overhead an
ATC facility the "dark spot" is of no consequence as you are pretty
close anyway.
There is another reason to stay with a dipole: A dipole has a certain
impedance and it is exactly this impedance (50 ohms) that became the
standard for the coax and output of the transmitter. Of course this is
no coincidence as the manufacturers know that the dipole is the best
solution. Other antennas might have a different impedance, need a
matching network (often built in and invisible to the user), and often
this matching network (consisting of coils and capacitors) breaks down,
causing all sorts of problems.
Just my 2 cents,
Frans

Hi! Thanks Greg.
That was me in G-PTAG Europa Trike (c/w Rotax 914) .
Just a bit slow in getting the flaps up but in hot, high, humid and "heavy"
conditions perhaps the "safe to be sure" policy is best. I remember another
one departing Lodrino with certain Jabiru 3300 and no turbo which was fine
for learning the hard way and perhaps best forgotten. Hope to be at the
Swiss EAA Event this year at LSGY. See you there!

Bob Harrison \G-PTAG

Thanks for all the tips folks.
I will track down an SWR meter and check out the system.
I will let you know how I get on.

| Subject: | CS Prop Controller - manifold pressure. |
We just fitted a Smart Avionics controller with our new Woodcomp SR3000
propeller. Engine is a standard 80hp Rotax 912.
I'm a complete newbie to flying with CS propellers and trying to get my head
around the manifold pressure settings.
The display on the Smart controller can be set for either air pressure (in
of Hg) or power setting as a % so I am wondering which would be best.
While I understand what the pressure readings mean it occurs to me that % of
full power is much easier to understand. With the pressure sensor currently
fitted, the percentage power reading becomes inaccurate with altitude but as
we rarely fly above 3,000 ft I cant see this being a major issue.
Any suggestions on which would be the most useful option and why.
Thanks in advance.

Hi! Carl
I much prefer to use the Manifold pressure settings then you will begin to
get the "feel" of "FUEL USAGE" and RPM combinations. I find that % power is
a bit of a misnomer. Best manifold pressure for my Smart Avionics is around
27" any more results in more fuel consumption and a labouring engine.
However my engine is a 914 so it could be a "bum steer" that I'm advising.
Mark Burton will probably better advise you since he flies (or did) using
the % setting with the smaller engine.
I used to have a battle with Jabiru since they would never provide any
power/ manifold pressure comparison graphs to give a target for RPM which
resulted in glazed bores needing to have new rings at very low Hours.

Hi Carl
If you look in the
http://www.reiffpreheat.com/RotaxOperatingManual.pdf Page 34
it gives you the run down on suitable RPM to MAP settings for any given
power output,
Like Bob i also use MAP instead of power,

| Subject: | Can the Monowheel be suitable for the tarmac |
Hi
I am a [proud] new owner of a classic Europa Monowheel from Rio Rancho NM.
Since there are no grass strips around here I have been working on landing
the Monowheel on Paved runway and found it very chalanging.
This difficulty planted some doubts in me as to wether the Monowheel can be
ever trusted to be safely, consistently landed on paved runways.
While somewhat rusty I have 200h+ of tailwheel time mostly in aerobatic
biplanes [Acrosport, Pitts] and monoplane [Sokhoi] I was surprised to
realized how chalanging the Europa Monowheel landings were -[The first day
it was with 12 - 15 Knots variable wind but the second one was with calm
wind]
I plan to take some more dual time but are starting to wonder if byond the
learning curve, would the Europa Mono ever be a safe plane for me to fly
around here and in x country [NM is a pretty windy place]
I would truly appreciate hearing the members feedback. I would also love to
find other Europa owners in my relative vicinity.
Thanks a bunch,
Ted I. Weitz

It can be configured as alternating, and that is what I did in the
beginning. However, I found out that the power % setting was meaningless
for me, and I was always waiting for the alternate MAP. So after a while
I configured it to display solely the MAP.
MAP is the real thing, the % power is derived from it but is inaccurate
and well, it is just a number which is pretty meaningless. MAP however
tells you, regardless of RPM, what is going on with your engine. Ok, I
have a 914, so I have additional reasons to observe MAP (it is also
showing the boost pressure). And if I want to compare performance
figures with other Europa flyers, I (and they) prefer to exchange RPM
and MAP to get comparable figures.
Just like Bob told, I too found out that 27 inch is about the sweet
point of my 914. The optimum in speed versus fuel consumption. Above
this, the fuel consumption climbs faster than the speed.

Ted it is a pussy cat on tarmac. You just need to not pull the stick
all
the way back on landing until after you have touched down (other wise
the
tail touches first and it bounces) and be very light on the ailerons on
the
ground so you don't put much pressure on the outriggers. Its easier
than a
Cub.
