An OV protection is to protect fragile devices against OVER VOLTAGE.
But you still need to protect THE WIRES in case of hard fault. That's
why a fuse or breaker is for.

Our project is wired according to Bob Nuckolls' philosophy, with
essential bus and dual battery. One fuel pump runs direct from the main
battery, and the backup pump from the auxilliary battery. The Rotax
rectifier/regulator has a very poor service record, and the Rotax
suggestion to use it to run the main pump does not seem very advisable.
Remember the 914 is an ELECTRICALLY DEPENDANT engine, and in case the
rectifier/regulator toasts, you'd be left with very few options. Unless
you design real electrical redundancy.
The architectures proposed by Bob Nuckolls are really worth examining.
Hope this helps,

Subject: | Centenary Fly In/Out - Turweston, 17/12/03 |
--> Europa-List message posted by: "David Joyce" <davidjoyce@doctors.org.uk>
Gloucester and Shobden Struts are joining in a fly in to Turweston on 17/12 and
welcome the Europa Hat Droppers to join them. We currently stand at 21 aircraft
intending to go (weather willing, naturally) but anticipate numbers increasing
to perhaps 40 planes. It gives us all an opportunity to inspect the new
PFA Headquarters, and the two Struts are marking the occasion by taking house
warming presents to the PFA in liquid form.
The airfield has a single 09/27 runway of 915m and we have Oxford earmarked
as an alternative should the day bring strong N/S winds. We are also prepared
to delay the fly in to 18/12 or 19/12 should the weather demand it. Although
normally PPR by telephone, for this event that will not be needed if you have
notified me of your intention to come. Please consult your Pooleys (or whichever)
for flying instructions but note especially the noise abatement procedures
with approach and departure to the N of the E/W line and the ban on overhead
joins. If the organisers at Turweston advise it and numbers merit it,we may
nearer the time suggest (via email) an assembly point flowing in to a down wind
join, in rally fashion. Hinton in the Hedges tell me that they will be parachuting
that day,if flyable so keep well clear if you want to arrive with both
wings on!
The normal landing fee is =A38 but the owner has said that they will reduce
this for the event (but has not yet come up with an exact figure)
There is one small restaurant which would seat about 30 but given notice
they will open up the much larger catering facilities in the new PFA building.
For this reason it is critical that we know the numbers intending to come.
Please let me know soonest if you will come if weather allows, ideally with
plane type and reg, + no pax. We can then give them numbers and reduce it nearer
the time if the weather is dodgy. All those who email back to me will be
kept updated with any modification of plans.
The timetable that the struts are working to is:
Arrive Turweston 11.30 to 12.00
Eat, talk and presents to PFA 12.00 to 13.30
Departures 13.30 to 14.30
Sunset approx 15.45
Happy landings, David Joyce

Gilles,
Thank you for sharing your thoughts. I am still curious about the need to
be able to disable the waste gate servo. My thoughts are about the
delectability of a failure and what remedial actions can be taken in flight.
Assuming I don't have a Flydat, how could I tell if the waste gate has been
commanded by the TCU to an incorrect position. Secondly, lets assume that
the TCU drove the waste gate to fully open or fully closed and I was able to
determine that this was incorrect, how could I move it from that position in
flight. Disabling the servo in this situation doesn't really buy me much.
I suspect that if the TCU failed in a manner that keep driving the servo
hard against the stops that it would cause enough over current to trip the
circuit breaker.

I agree we want guaranteed and/or redundant power supply to at least one 914 fuel
pump, but I can't find actual data to class the reg as very poor, though.
There are anecdotal reports, but FAA's Service Difficulty Reports -- as as voluntary
program it's a database of anecdotal reports also -- shows no alternator/regulator
failures. It does cite other problems, many familiar in Rotax service
bulletins.
A reasonable issue is heat, so I've mounted the regulator in the tunnel (have tri-gear),
rather than in the the engine room.

Fred F.

Hi all,
I've directly heard of several such failures. I recently took some pictures
of the internals of a failed rectifier/regulator. With a fellow pilot and
electric engineering researcher, we are performing some tests on a Rotax
alternator and rectifier/regulator.
Below is a copy of a message on the Aeroelectric List some weeks ago. The
subject was Rotax rectifier/regulator reliability.
Regards,
Gilles
>What is the problem with the original rectifier/regulator from Rotax?
The standard rectifier regulator supplied with Rotax 912/914
engines is, I believe, made by Ducati. Ducati makes a whole
raft of ignition and power generation products for small engines
where the largest markets are for all manner of recreational
vehicles . . . a tiny portion of which is aircraft.
If you do a websearch on ducati "voltage regulator" and rotax
you get a bunch of hits. Far too many of those posted articles
talk about making the Ducati part last with most
of the "fixes" going to keeping the part cool.
My experience with Ducati parts suggests poor attention to
design with respect to keeping internal parts of the regulator
within their best operating temperature range. B&C's "heavy
duty" regulator was nothing more that the standard circuit
with robust, well heat-sinked parts.
Do some research on the web and I think you'll get a sense
of how much trouble folks are having with what should be
a no-brainer.
It would be a step forward to simply improve the thermal
design of the current design. If I understand what Gilles'
friend is attempting, we should be able to replace high-voltage-
drop rectifiers with low-voltage-drop power field effect
transistors. It's a much more complicated design but promises
to offer much higher efficiency -AND- ultimately higher current
carrying capacity. 18-20A is pushing the practical limits for
the current design.
Bob . . .

Maybe some shortcoming in the TCU software..

Surge should be noticeable by unstable manifold pressure and/or engine power
output.
Secondly, lets assume that

TCU trouble may not necessarily relate to driving the waste gate to the
stop, but raher to inappropriate pressure/flow rates leading to MP
oscillations. The problem is very well known to jet engine or turbo people.
But in our cars those problems have been caterd for.
According to the Rotax 914 installation maual, in case of surge,
disconnecting the turbo servo should restore stable operation after a few
oscillations.

Hmm, IF Rotax people did their homework, the waste gate servo is a real
servo with built-in limit switches
Just my thoughts,

Gilles

Gloucester and Shobden Struts are joining in a fly in to Turweston on
17/12 and welcome the Europa Hat Droppers to join them. We currently stand
at 21 aircraft intending to go (weather willing, naturally) but anticipate
numbers increasing to perhaps 40 planes. It gives us all an opportunity to
inspect the new PFA Headquarters, and the two Struts are marking the
occasion by taking house warming presents to the PFA in liquid form.
The airfield has a single 09/27 runway of 915m and we have Oxford
earmarked as an alternative should the day bring strong N/S winds. We are
also prepared to delay the fly in to 18/12 or 19/12 should the weather
demand it. Although normally PPR by telephone, for this event that will not
be needed if you have notified me of your intention to come. Please consult
your Pooleys (or whichever) for flying instructions but note especially the
noise abatement procedures with approach and departure to the N of the E/W
line and the ban on overhead joins. If the organisers at Turweston advise it
and numbers merit it,we may nearer the time suggest (via email) an assembly
point flowing in to a down wind join, in rally fashion. Hinton in the
Hedges tell me that they will be parachuting that day,if flyable so keep
well clear if you want to arrive with both wings on!
The normal landing fee is =A38 but the owner has said that they
will reduce this for the event (but has not yet come up with an exact
figure)
There is one small restaurant which would seat about 30 but given
notice they will open up the much larger catering facilities in the new PFA
building. For this reason it is critical that we know the numbers intending
to come. Please let me know soonest if you will come if weather allows,
ideally with plane type and reg, + no pax. We can then give them numbers
and reduce it nearer the time if the weather is dodgy. All those who email
back to me will be kept updated with any modification of plans.
The timetable that the struts are working to is:
Arrive Turweston 11.30 to 12.00
Eat, talk and presents to PFA 12.00 to 13.30
Departures 13.30 to 14.30
Sunset approx 15.45
Happy landings, David Joyce

There IS a difference between an elevator and a stabilator. The
first changes the shape of the control surface, such that a
down elevator curves the elevator/stabilizer control making it more
sensitive to unwanted wind vagueries. The stabilator does not
change shape so is not as sensitive (say to tipping up the tail from a
tailwind). Judging the severity of the effect is a Command decision
and comes mostly from experience

upwind wing down?
Because of outriggers, the problem of preventing wing-up events
tends to be less critical. Nevertheless it is good practice to select up
aileron into wind o spoil any potential lifting tendency. All of this
of course depends on the strength of the gust/wind. I would believe
any sidewind meeting a lifting surface would tend to reduce
directional control, even slightly.
>As far as the elevator, for all i know perhaps the huge prop spinning puts
flow from >front to back instead of back to front?
I dont believe (with a tailwind) you will want to add to its effect
by increasing speed/power with the prop. The only time to
blast with power is to correct a sudden swing - and then only for an
instant. This is a neglected practice, but a vital one in a Boeing
Stearman. Otherwise, throttle back.
>I honest don't know, but my guess is full forward and full to the right.
I wont do that. You are reducing the one thing giving directional
control - the tailwheel. Besides, I dont think theres a hard and fast
rule for any control position. If you sense a threatening tailwind,
stick full back because the stab will be stalled and you may be adding
weight to the tailwheel.
Stick to the LEFT (port) if the wind is there. Stick into wind to dump
lift on that side (reduce camber).
Of course, these remarks are a personal attitude and open to any
correction - I may have misspoken.
a personal experience. I shared a Stearman belonging to He in
the Back Seat, a naval cadet grown to senior years and open to gossip and
hearsay (much as do sailors referring to local knowledge as a valued
item). When I questioned him on a burp in the Continental on final to
Mitchell SD, he replied, the old guys tell me it clears its throat every
once in a while. When I insisted on asking the mechanic, he found one
magneto arm cracked and taking on moisture, and the other even worse! We
were there three days till the parts arrived - BUT we had overflown Lake
Ontario and northern NY (trees) enroute. No engine clears its throat.

We have the factory supplied fuel return, and tested the return flow
immediately after the last 'vapor lock' incident (return flow was about
2.2 gph, which is the same as it was 300+ hours ago at initial engine
startup). The most compelling evidence of vapor lock was as follows;
I shut the engine down in flight at about 8,000 feet altitude, to test
the glide ration with the prop fully feathered (it was about 13:1, as I
recall). On restart, the engine ran rough, worse at higher throttle
settings. I finally turned on the boost pump, which killed one back of
the engine momentarily, with the fuel flow going from about 5 gph to 9
gph, momentarily. After pulling the throttle back (and turning the
boost pump off) the engine ran better, and by the time I got into the
pattern at the airfield I had been testing over, the roughness was gone.
It is my assumption that there was a vapor lock partially blocking the
fuel flow. At higher throttle settings the blockage causes rough
running (perhaps only on carb is affected). When I turned on the boost
pump, I believe it forced a 'bubble' of vapor through to the carb(s),
killing that side, and caused the momentary surge in fuel flow.

Our cold starting problems have been because our carbs are not sync'd

the blue sky disappeared and a 1300 overcast appeared. I ended up doing one circuit
(pattern). Air temp was 4 celcius (40 F) no misfire but I hardly used a
steady throttle ! I have fixed my throttle lever box problem and the throttle
cables are now pulling evenly. I haven't got the balance right as it shook a bit
at 5000 but was OK at 4800. However as in the past the misfire problem seemed
to "accumulate" - appearing on a second flight in a minor way and on a third
flight worse I need to fly more ! In each case in the past the misfire went
away after less than 60 seconds and a change of throttle setting.

Hi guys,
I'm trying to source a (low) fuel pressure switch for use with a 912s, with nipple
connections suitable for the Europa's finest rubber fuel tube. I've studied
the archives, and all leads so far have dried up. Does anyone know of a uk supplier
of a suitable switch? I assume a switch that would operate at about 3
P.S.I. is about right.

A female spade connector (.e.g., Faston) works at least adequately. Install an

The regulator referred to is not made by Ducatti but by Tympanium, follow
this link for more info: http://www.tympanium.com/app.html
As with all permanent magnet alternator shunt regulators you need to ensure
the heat sink face is attached to a metallic surface.
Screwing them to a plastic firewall inside a hot engine bay is part of the
problem.
Poor AC and DC wiring/connections to and from the regulator and alternator
is another.
Inadvertently disconnecting from the battery whilst the engine is running
is
another.

Yes, not forgetting to mention that Martin Stoner's problem was one of
geometry.
That is, the outriggers would do a very good job of stabilising the wings
(when on the ground) IF the axle line of the outriggers were coincident or
even ahead of the main wheel axle line.
As they are not, then under the action of a cross camber and/or quartering
tail gust and/or exacerbated by braking, the a/c can tip to the 11 o'clock
or 1 o'clock positions more easily than to the 12 o'clock position.
Monowheels are in good company though. The Jabiru with its short-coupled and
narrow-tracked TRICYCLE undercarriage can do the same. Even when stationary
in a power-check!

Does not compute!
The centre of mass of the trim tab AND the extra lead/steel needed to
counterbalance it is forward of where tail ballast would be added. So more
weight in total will be needed. This is the same principle as your (correct)
argument for incurring additional total weight for a battery mounted in the
rear.

Graham,
Thank you for your message.
The regulator I was speaking of comes in the crate with the Rotax engines.
It has Ducati Energia stamped on it.
It is not a shunt regulator.
The problem is, there is no real thermal connection inside between the SCRs
and the beautifully finned case. The SCRs are soldered on the PCB and
encapsulated in some plastic stuff, with no heat sink.The soldering
thechnique seems rather crude.
I can send pictures of a dismantled unit to those interested.
As most builders in our area use lots of amps with the 914, the regulators
run pretty hot INSIDE.
They are usually installed with a 22000 uF capacitor in addition to the
battery, to prevent any disconnection problem.
Regards,
Gilles

Subject: | Fitting Stall Stips |
--> Europa-List message posted by: "Carl & Dot" <carl_p@ntlworld.com>
Does anyone that is flying have any views regarding the fitment of stall
strips. We were initially advised that these were a bad idea and that an
electric stall warner was a better option. From what I remember, stall
strips are supposed to have an adverse effect on the landing characteristics
of the aircraft.
We just recently completed our annual test flight and were a little
concerned that the aircraft has a habit of stalling left-wing down. With
the flaps up this is fairly benign, but with the flaps down is fairly
dramatic. The wing drops are easily recovered using standard techniques but
it would be nicer if we could eliminate this problem somehow. I discussed
this with several people last year and they were of the opinion that the
wing drop could be caused by the aircraft being out of balance prior to the
stall, however we tried repeated stalls with everything in balance and there
is still a significant drop to the left.
Has anyone attempted to eliminate a dropped wing by playing around with the
positioning of the stall strips and if so how successful was this. For the
time being we are relying on an electric stall warner which is excellent and
we are very happy with it but it would still be nice if we could get the
wings to stall in a more symmetrical manner, not that we intend to make
habit of stalling the aircraft.
Also what effect do stall strips have on landing/ takeoff performance.
Carl Pattinson
G-LABS
PS: If you fitted stall strips, how close to the factory reccomendations did
you end up. The book says about 12ins outboard of the fuselage and slightly
below the centreline of the leading edge (as per the template).

Paul;
About a year ago on a flight from South Fla., I was about an hour away from my
home base at Leesburg, in normal cruise, at 5300 RPM and 33" MP. The red over
boost light came on. I looked at the MP which was normal, RPM was normal. I then
turned off the "switch" for about 5 seconds then turned it back on. The TCU
recycled itself, the red boost light went out., and I continued the flight home
with no further problems.
In the maintenance manual for the 914 there is a section on troubleshooting the
servo and the red and yellow lights. The switch is part of the system and it
needs to be installed.

Paul,
Further to the previous answers, there are two principal reasons for having
a switch between the alternator output and the bus bar: first, to enable the
bus bar to be isolated from the alternator in the event of an electrical
emergency (if smoke came out of the wires, switching off the battery master
would still leave the alternator feeding the bus as long as the engine was
running); second, having followed the Rotax recommendation to feed one
electrical pump for the 914 directly from the alternator, the bus isolation
switch avoids that pump running from the battery whenever the battery master
switch is on with the engine stopped (e.g. if you wish to set up way points
on your GPS before starting).
The reason for having a slow-blow fuse is to avoid nuisance trips caused by
current surges. This requirement can be satisfied with a standard (as
opposed to a "fast-acting") fuse. However, if you are planning to
incorporate overvoltage protection you will need a circuit breaker and an
alternator relay rather than a fuse to follow Bob Nuckolls' advice (see the
Air Electric Connection circuit Z 7 designed for permanent-magnet

Hi all,
I am at that interesting stage (not sanding & filling). I have a couple of
questions.
1. The Rotax engine monitor shows a double pole switch that is for
disabling the waste gate servo. Why would I want this, has anyone fitted
this ?
2. The Europa manual shows a 25 amp switch for between the alternator
output and the main buss. I intend to install an OVP so I don't see the
need for an additional switch, am I missing something here.
3. Last question, what have folks been using for 30 amp slow blow fuses.
The only thing I have come across is fusible links the Bob Nuckles uses
which I don't particularly care for.
My current thinking is an E-Buss feed arrangement with an auxiliary battery,
but to still feed one fuel pump (914) directly from the alternator output as
described in the Europa & Rotax manuals.
I welcome any comments.
Thanks, Paul

err! ! ! - I think we're arguing about semantics here.
Both the extra weight of the hardwood trim tab and the increase in
counterbalance weight is still significantly rearward of the aircraft's Cof
G. The combined mass of stabilator and counterbalance has a C of G
coincident with the torque tube. Sure, strictly speaking, as the lead in
the fin post is rearward of the torque tube, a lighter stabilator will
result in a very slightly lighter finish due to the slight rearward position
of the lead weight exerting an increased and more effective moment. In
practise, this longitudinal difference- torque tube to fin post - tends to
zero and therefore the weight of the stab assembly will have very little
effect on overall aircraft weight.
There comes a point where you have to consider practical reality rather than
worrying about every last nanogram! - The point I was making was that, given
a weight disadvantage of effectively zero, I would prefer not to pratt
about with balsa but use something more serviceable and durable - common
sense really. If it remains an issue for anyone - use hardwood flettners
for robustness and then pluck your nasal hair before you fly in order to
achieve the same end result! !

I had the same on my plane. John Hurst helped with the testing. We added
one trip to the starboard wing as per the factory. I used double sided tap
at first so we could get it in the right place. After three tries, we got it
so the stalls are straight ahead and level. ( or at least not always left
wing down)
I just cut a 3/4" piece of pine board on a 45* lengthwise. Hollowed out the
inside surface to match the leading edge of the wing and used double sided
carpet tape to stick on the wing. The strip has a 90* angle on its leading
edge.
