fwiw, up here in the frozen tundra when spring comes with the warmer
weather and the stations are slow to switch their premium tanks over due to
lack of volume, we also see lots of running issues and vapor lock with the
"winter gas" formulation.

Hi William,
Had to reduce the spacer lengths to 1.500=9D to deal with the very la
rge
startup and shutdown movements of the high compression 912ULS. That said I
believe Erich with his lower compression 914 got away with 1.592=9D w
hich I
found to be *really* quiet and smooth - except with my 912ULS it would bang
around during startup and shutdown (when I had the heavy and gear-box
abusing warpdrive, I may be able to lengthen them with my now super-light
E-prop).

It will vary but winter mogas has typically 10% more butane to help it start in
cooler seasons, butane has 20% less energy than gasoline and evaporates easily
so it doesn't age well in a vented tank.
The EPA mandates the Ried vapour pressure =RVP, and butane is how they adjust this.
Mogas usually more volatile than 100LL.
100LL has additives to reduce icing and static and anti oxidents to prevent gum
build up, it ages well. I would suggest buy a spcific gravity tester, from Fisher
Scientific, only $20 when I bought mine. Good to know what's in the tank.

That is a good bit of info in that link.
Another useful test if running pump gas, or even avgas, is to check for ethanol
content of the fuel before putting the fuel into the aircraft; its a simple and
quick process and can prevent carbi icing scenarios.
Basically take a glass container put 100ml of water in, draw a line at the water
level, put 100ml of the fuel in the container and give it a stir; if the water
level increases then thats the % of ethanol in the fuel.

Bob - I hope that many members will support this - it looks a good idea.
Am I correct in thinking that the intention is to show home addresses,
NOT aircraft bases? With so many Rotax engines being stolen, I would not
want to have pointers published that thieves could use to locate
potential targets. Yes, I know the map will be members-only, but the
black hats may well have the tools to circumvent website security as
well as the ones used to liberate engines!
I=99ve recently been doing something similar with online maps
using the Leaflet templates, which I found really easy to use - see:

Hi Rowland
The suggestion is to create a map with the approximate position of the Members
home. This is achieved by using a truncated version of the Members postal code.
This map to only be available to Members using the password privileges.
In the settings page both new and existing Members can define if they are happy
to release personal detail in the Membership settings options:
https://www.theeuropaclub.org/members/
Currently 23% of the Europa Club Membership have positively selected that they
do not want any personal information disclosed (including by default map information).
The Club will respect the Members wishes. So the map would show 77% of
locations if active today.
In respect of thefts from airfields the Europa Club is acutely aware of the sensitivity
of the subject. The Europa Club has no intention to publish at this time.
Poignant, my home airfield was targeted Christmas 2020. The theft of engines, including
mine, was traumatic! Installation of high tech, high cost security security
equipment and processes followed.
Regards
Bob

Hi Rowland,
The intention is to use the first part of an individuals post code for their location.
This will identify the general location, but not the specific address
of the individual. The individuals name and email address would be displayed,
but not their address or phone number. In this way, an individual can be
contacted, but it is then up to the individual to decide if they wish to engage.
Best Regards

Hi Pete Z.
In May 2018 the privacy GDPR laws changed in the UK & EU. The laws are very different
in Canada and the USA. This side of the pond there is the threat of fines
or other sanctions for publishing a Members contact details without permission.
Consequently we are obliged to proceed cautiously and with consent. The Europa
Committee will likely review and decide at the next Committee meeting.
Thanks for the feedback
Regards
Bob

I like this idea in that it allows members to be aware of where other members may
live in general. The email info would allow for contact in a general sense.
Remember, there is still the emergency contact list for those traveling that might

| From: | "JonathanMilbank" <jdmilbank(at)yahoo.co.uk> |
UK Classic and possibly XS owners who have recently been informed by their inspectors
to comply with Mandatory Permit Directive MPD : 1998-019 R1 subject Flexible
Fuel Tubing. I WANT TO SPLIT THE COST WITH YOU.
After measuring generously, the total length I need is 7 meters / 23 ft. Looking at the LAS website, I ascertain that 23 ft at 4.14/ft will cost 95.22 and probably delivery + VAT to be added. But its "provenance" is debatable, even though LAS Aerospace Ltd no doubt has impeccable credentials. https://www.lasaero.com/products/article/S03RCYQ1X
My inspector is keen for me to acquire TYGON, which fulfils the MPD requirement as "tubing manufactured from an identifiable material" and so he provided me with this link to Tubing International https://www.tubinginternational.com/cart/ which comes in at 167.24 incl shipping and VAT. That gets me a 50 ft / 15 meter roll, which is more than double what I need. Would anyone like to buy the leftover half roll from me for, shall we say, 70.00 incl shipping?
Looking forward to a stampede of replies. Jonathan

| From: | "h&jeuropa" <butcher43(at)att.net> |
Jonathan,
I certainly do not know LAA requirements, but I can share my sight gauge and fuel
hose experience.
I tried Tygon F4040 fuel hose initially. It will get hard and lose flexibility
in less than a year as I recall. It is yellow initially and gets more yellow
with time.
What I have been using for the last 6-8 years is Tygon SE200. This is clear tubing
with a Teflon liner. There has been no change in color or opacity since
installed. The liner will not withstand flexing, so for protection, I slid the
SE200 inside clear flexible tubing that I purchased a the local DIY store. The
only place I use this is for my sight gauge.
All other fuel hoses in my Europa are Gates Barricade, which meets SAE J30R14T1
specification. This hose has very low permeation so smell is minimized. It comes
in carburetor version and fuel injection version. The fuel injection hose
is stiffer and more difficult to slide on fittings but also will keep it's shape
better around sharp bends. The carburetor version is softer and easier to
slide on fittings but can collapse or deform around sharp bends.
I also have replaced all barb fittings in my fuel and oil system with AN style
hose ends. They are much easier to work with than the original Europa barb fittings.
Hope this helps but I have no idea if allowed in the UK.

Jim,
Many thanks for your words of wisdom. As you're probably aware, in the UK we seem
to enjoy less freedom and are subject to detailed annual permit renewal inspections.
So if my inspector says "Jump!" then I reply "How high Sir?" At last
year's inspection he told me that he would like me to replace the sight gauge
tubing before the next inspection, preferably using the TYGON which seemingly
is being used by several UK aircraft types.
I'll have to keep my fingers crossed, hoping that it lasts as long as what is currently
installed and still in quite good condition after 26 years. Unfortunately
the old tubing was supplied by Europa as part of the build kit, with no way
now of knowing who manufactured it. The picture of what I've already ordered
shows fairly clear tubing without a hint of yellow. It'll be interesting to
see what comes out of the package.
My other hope is that the formulation of US mogas may be a little different from
the UK. For one thing, we can still buy mogas at certain fuel stations with
zero ethanol in it, which is what I always use.

Jonathan you could find another inspector. Thats what happens when I tell LAA members
something they dont like at permit time. Especially if it involves them
spending money or their aircraft maybe grounded. Safety usually comes a poor
third. Not sure why after all this time your inspector is quoting MPD 1998-019
R1. Unless he's new to you. Its been around since 1998 and should be carried
out every permit renewal inspection. I carry it out on any aircraft it am carrying
out a Permit renewal inspection on. I inspect all flexible lines and hose
for deterioration. Not just fuel lines.
I have only found out about Tygon hose in the last week. I've only ever used standard
commercially available fuel hose. I change it on-condition. Because its
cheap it gets changed often as needed and not every 26 years. If I was going
your inspection I would suggest that to you. Unless you really want Tygon hose
at that is.

| Subject: | Europa fuel sight guage shorter route up seat back |
| From: | "JonathanMilbank" <jdmilbank(at)yahoo.co.uk> |
After looking through documents available at The Europa Club, LAA Europa TADS and
my paper documents, I can't find anything giving Mod approval or instructions
/ diagrams on how to re-route the fuel sight guage from the tank outlet in
the tunnel and up the seat back, which several Europas seem to have done.
I'm considering doing this, but need to have some documentary support to show my
inspector. Please help. Thank you.

| From: | "n7188u" <chmgarb(at)gmail.com> |
Per Jim's recommendation I also used the SE-200 tubing. For those in the US it
is sold by McMaster Carr as "Ultra-Chemical-Resistant Versilon PVC Tubing 1/4
ID, 3/8 OD" PN 6519T13. The stuff is great and after 3 years it has not stained
and remains crystal clear making reading the fuel level very easy.
However, I installed my tube right against the cockpit module's seat back in the
center (if someone has seen Bud Yerly's airplane, but without the fancy base).
That means I did not have to bend this tube to place it in the foot well as
the plans indicate. I have 1/4" aluminum tubing from the tank and vent and bent
90s at the top and bottom of the seat back center. From there a straight run
of the SE-200 against the seat back. No bends.
Jim is right, the stuff doesn't like bends because the FEP liner inside will collapse.
But in a near straight line it is amazing for fuel sight gage use. Also,
pushing the tube into the 1/4" tubing is hard because the liner separates and
bunches up in front of the tubing. But with some patience it is doable. Certainly
worth the effort.
But I don't know if you can change the location of the fuel sight gage in England.
Could you use barbed fittings and use the SE-200 only on the vertical run
where you read the fuel level?
Honestly, I have no clue why Europa didn't place it against the seat back. Easy
to see and fairly accurate.

| Subject: | Dynon HDX Autopilot Settings |
Hi folks,
I'm back in the air after determining my no generator issues were due to
a poor connection.
When I first installed the Dynon Autopilot on my HDX system, it worked
right out of the box using the default settings in terms of
sensitivities, gains, etc. for both roll and pitch.
A software upgrade introduced a tendency for an aggressive roll tendency
when initiating a turn. Others on the Dynon forum had the same issues.
Then another software update provided 'the fix' but it was also clear
that for me the default settings no longer worked in the pitch axis.
I have gone through the process for adjusting the settings as provided
by the autopilot tuning manual but it still 'wanders' having captured
altitude quite nicely.
I'm thinking of asking Dynon how to reinstall previous software versions
but then I thought I would ask anyone who has a Dynon HDX system with an
autopilot who is running the current software if they could send me
their settings.
Any pointers would be appreciated.
Regards,
Martin Tuck

| Subject: | CKT silencer crack |
| From: | "JonathanMilbank" <jdmilbank(at)yahoo.co.uk> |
This damage looks difficult to repair by welding. The "collar" into which the exhaust
header tube is held with springs, has broken the weld most of the way around
where it attaches to the silencer box. There are other broken small welds
where the other header tubes get inserted.
Throughout the 300 hours total in the air since the silencer was first installed,
the carburettors have been kept electronically balanced and the Airmaster propeller
is also well balanced. The silencer was suspended with utmost care to
avoid strains as the flange nuts got tightened, making sure to tighten the telescopic
joint in #1 header tube last.
I'll probably have to replace the whole exhaust system. This topic is just FYI.

Hope your keeping well?
I had a very similar failure with my silencer at around the same number of hrs
on my aircraft, new silencer was indeed required.
I have just had the number 3 cylinder down pipe fail on friday afternoon whilst
flying. The Number 2 down pipe had no more than 30hrs on it before the failure
Hope you can get things fixed soon.

Hello All
Im considering the Beringer wheel and looking for experience of others with Beringer.
Ive had 3 pinch flats on my mono and will get the better tubes and higher
inflation to help prevent future failure but still concerned about being stranded
on a strip.
Perhaps the tubeless tire Beringer will work better and still allow for less tire
pressure and help with landing. Also the added breaking power.
Thanks for any input and advice!

Jerry, I was delighted with how well it worked for me. Clearly better
braking and lighter. My only cabeat is that it is possibly a mistake to
fit it with the bicycle brake style lever on the P1 column. You may come
to want to be able to brake from P2 position somewhere down the line, so
I recommend a lever system in the conventional Europa position. David

Hi Jerry,
I fitted the Beringer wheel 6 years ago and I am very happy with the performance
as the braking is progressive without being too powerful. Make sure you get
the pressure limiter which is what provides that feel.
My system came with the stick mounted brake lever, I hesitated to send it back
but thought I would give it a try especially as Beringer offered to swap it if
I wasnt happy with it.
It took several flights to get used to it because initially you feel like you should
be doing something with the right hand but once accustomed to it its really
pleasant for just that reason. It frees up your hand to do other tasks when
taxiing but giving you constant control over your braking inputs.
I used the 7 Air Trac tyre on my mono.
As David pointed out an issue could be if you instruct on your aircraft but thats
not something I envisage doing. I suppose you could add a second brake on the
other stick but it would increase cost and add weight and you wouldnt want
the uninitiated playing with it!
If you have had several pinch punctures you cant be far from a prop strike with
a fully compressed gear and compressed tyre.

Here is how my centrally mounted brake lever looks. There is a park
brake button just out of view on pax side of installation. Ergonomic
inasmuch as very close to throttle. Installation fairly complicated but
well within abilities of anyone who has built his plane. I am not an
instructor but have found myself flying from R hand seat on a number of
occasions over the years and as we all get older and probably do more
buddy flying it is comforting for either pilot to have ability to land
the plane. David Joyce

Im having some Europa hats embroidered. The attachment shows how they will look.
They are adjustable so one size fits all. They can only be mailed to US and
Canada addresses. The cost delivered is $27. If anyone from outside the US / Canada
is interested and will attend Oshkosh, I could bring their hats for pick
up.
I previously emailed directly to my North America Zoom list. Before I obtained
a quote, some expressed interest. After providing the price to those interested,
some agreed to purchase. Some that expressed interest have not responded whether
they want to purchase knowing the price.
To add another wrinkle, some want hats but without the word Club. The supplier
has agreed they can produce hats with the word Europa and the airplane artwork,
with or without Club, at the same price.
Anyone interested please let me know the following via PM or email America(at)theeuropaclub.org:
If you have agreed to purchase, do you want with or without Club on your hat(s)?
If you expressed interest but havent agreed to purchase, I will assume you do not
desire to purchase if I dont hear by Wed 3/8.
If you havent responded previously and wish to purchase, let me know and advise
whether you want Club on your hat(s).
I plan to place the order Thursday 3/9. Payment can be check or PayPal. I will
advise payment details after I place the order.
Thank you.

> Hello All
> Im considering the Beringer wheel and looking for experience of others with Beringer.
Ive had 3 pinch flats on my mono and will get the better tubes and higher
inflation to help prevent future failure but still concerned about being
stranded on a strip.
> Perhaps the tubeless tire Beringer will work better and still allow for less
tire pressure and help with landing. Also the added breaking power.

Apologize for repeat on this, I am not getting replies from matronics.
Went to their site and I see one reply, so thanks!

I have the Beringer complete kit but no hours using it yet. It's been on the market
about 10 years many Europa owners have been using it. In the beginning there
were worries expressed about it getting flats too or rotating on the rim at
low air pressure but I have yet to read one post with any complaints, that says
something.
The other issue is do you use the motorcycle style brake handle? My answer is a
Big Yes! It is much better ergonomically for a pilot.
I can hold the stick back with brake applied by the left hand while I advance the
throttle with the right hand, it's great. It's complete with parking brake
and a anti lock brake type feature that is actually a pressure limiter, you don't
have to install this feature but why not?
I run the brake line into the cockpit through the landing gear frame tube.
The Brake disk won't ever rust, it's SS, twice as thick as before. Aug 15, /22
posted some photos of my installation, "what did you do with your Europa"
I'm sure you will get other comments but I think it's a real improvment.

Jerry the photos of the Beringer wheel & brake were posted 8/15 2022 but they are
to be found in the 8/12...2022 " what did you do with your Europa last week".
I chose the Airtrac 800-6, here is a photo of the Beringer with 800-6 beside a
700-6.
The 700-6 is 0.7 lbs lighter and 1/2" shorter and 1" narrower. The total weight
of the wheel and brake with 800-6 Airtrac is 19.99 lbs. or 9.07 Kg, take your
pick.

| From: | "h&jeuropa" <butcher43(at)att.net> |
Brad Shafer is having problems posting here, so I am forwarding his Facebook posts.
Like many others, I woke up to gas on the floor and a crack in the tank.
Mine was low on the saddle. I liked what Dave Disney had done so I drained the
tank and created an opening in the top. With the ability to inspect the inside
of the tank (which is a very nice option to have!), I found another narrow crack
in the bottom corner that must have been there for awhile.
Given the placement of the cracks, I couldn't find a way to gain access with a
heat gun so I needed to find another option. I found this (https://tbbonding.com/)
as an option to patch poly tanks. I talked with them and felt good about
trying. I like the idea that the patch is flexible and will expand with the tank.
Jim Butcher
Worst case, it doesn't work and I do the full tank replacement. The bonding process
was straight forward and fairly easy with access to the inside of the tank.
So far it is holding well after 6 months but I'm going to do some more testing
to make sure.

Found a nice solution for artwork on our Europas. I worked with Alwan Wraps in
Michigan (sales(at)alwanwraps.com). For $250, they created a CAD image of a trigear
and worked with me to layout the artwork. And then the decals were $450 including
the tail and wheel pants. I'm assuming that anyone else wouldn't have to
pay the full $240 since the CAD work is done already. See attached pics. Really
happy with the results.

For my panel, I used Front Panel Designer. They have a great free design tool and
create/ship the panels fairly quick in the US. The hard part was getting the
panel outlines into CAD to start. From there, it was actually kinda fun with
their design tool. The cost was between $50 and $175 depending on the thickness
and complexity (2mm or 3mm). Let me know if anyone wants the CAD or Front Panel
Designer files.

| From: | "tonyvaccarella" <tony(at)weimagine.com.au> |
Hi everyone,
Im wondering if anyone else has encountered this problem with the trim damper assembly
as I have.
>From Page 19-2 - Figure 2, the TS04A bolt is placed through the support bracket
- however, when I installed the Nyloc Nut M10 and putting in safety (only by
about 1 thread). The spring is fully compressed and causes binding with operating
the electric trim.
I can't see an easy way out of this and I have been thinking of removing the spring
and cutting one or two spirals of the spring.
Can anyone kindly offer some wisdom on this?
Many thanks

Hi
That is one good looking aircraft. One thing that worries me though is
if you spill fuel whilst re-fuelling, will it damage the decals?

Not had a problem.
Whenever Ive come across something thats doesnt seem to work I always go back to
the manual to check I have the right items and assembled them correctly.
For example the thickness washer placed under the head of a bolt instead of the
nut meant the shoulder of the bolt did not go all the way through a control rod
end resulting in too much play in the control. Corrected and all works fine.

Well, now that flying the europa is starting to become a bit more second nature,
do we make it more enjoyable to fly?
Really don't enjoy the noise of a racing bike any more; so its time to shut those
fricken carburettors up!
Today has been a day of distraction, instead of fitting new hydraulic hoses to
some heavy machinery, and there's nothing better than playing with a europa..
The plenum box has been extracted and Cad'd up to analyse its flow and acoustic
aspects; its basically currently acting as a fantastic resonator boosting induction
noise straight through the firewall.
Today has been spent looking at Mass Flow and Dynamic Pressure through the assembly
at 6000rpm WOT.
The target objective will be implementing passive noise attenuation features to
mitigate carburettor induction noise ingress to the cockpit.

Brad Shafer is having problems posting here, so I am forwarding his Facebook
posts.
Like many others, I woke up to gas on the floor and a crack in the tank.
Mine was low on the saddle. I liked what Dave Disney had done so I drained
the
tank and created an opening in the top. With the ability to inspect the
inside
of the tank (which is a very nice option to have!), I found another narrow
crack
in the bottom corner that must have been there for awhile.
Given the placement of the cracks, I couldn't find a way to gain access with
a
heat gun so I needed to find another option. I found this
(https://tbbonding.com/)
as an option to patch poly tanks. I talked with them and felt good about
trying. I like the idea that the patch is flexible and will expand with the
tank.
Jim Butcher
Worst case, it doesn't work and I do the full tank replacement. The bonding
process
was straight forward and fairly easy with access to the inside of the tank.
So far it is holding well after 6 months but I'm going to do some more
testing
to make sure.

Brad Schafer is having problems posting so I am adding his Facebook posts.
Found a nice solution for artwork on our Europas. I worked with Alwan Wraps
in
Michigan (sales(at)alwanwraps.com). For $250, they created a CAD image of a
trigear
and worked with me to layout the artwork. And then the decals were $450
including
the tail and wheel pants. I'm assuming that anyone else wouldn't have to
pay the full $240 since the CAD work is done already. See attached pics.
Really
happy with the results.

For my panel, I used Front Panel Designer. They have a great free design
tool and
create/ship the panels fairly quick in the US. The hard part was getting the
panel outlines into CAD to start. From there, it was actually kinda fun with
their design tool. The cost was between $50 and $175 depending on the
thickness
and complexity (2mm or 3mm). Let me know if anyone wants the CAD or Front
Panel
Designer files.

Stage One of "shut that noise up" has been a flying success!!!
Worth every one of the 1000g weight penalty; couldn't recommend it more.
The mod has worked so well that noise canceling is no longer required.. in fact,
its worse now flying with noise canceling than without... at WOT engine noise
has gone from high pitched screaming hell to a dull drone... at cruise you could
have a cockpit conversation without headphones; its just so much more relaxing
and enjoyable... over the moon with the result...
Weight & Balance has been affected by moving the CG more forward; with 10L fuel
the cg crosses the forward boundary.. so i just have to t/o with 50L on board
to balance out closer to center.
Planning on adding a bit more aft weight so not too concerned.
Will still apply Stage 2 internal baffles to shut things up even more...

Experience is now a low frequency drone from exhaust along with slight level of
low frequency carburettor noise; so can still hear the engine and gearbox, its
just not a high frequency or high volume level.
At cruise the noise volume of engine and air over the canopy is about equal.

Peter, the material functions by absorbing specific high and low frequency waves
of the audible spectrum; its material design purpose is for eliminating resonance
drumming on automotive panels.
The plenum box on 181 is very thin fibreglass, so its like a drum skin stock untreated.
Everyone's ears will respond somewhat differently to sound waves, so results will
be perceived differently.

Area-51,
Great feedback and thanks for sharing. Could you share more details, such as specifications,
on the soundproofing material and the 3M adhesive used. I searched
for Driver Consolidated Industries (DCI) and 3M Magic Tape and found nothing.
I love my Europa except for, as you describe and I have done too, the "Screaming
from Hell"! I am going to try this right away since if it is as you describe
my Europa will go from "Great" to "Fantastic".
Since I am going to take my airplane apart for painting I was considering installing
a Firewall Blanket to reduce the screaming. I wonder if anyone has done
this, results, and if positive materials used.
Best,
Chris

A-51,
I have this material that I purchased a while back in an attempt to use something
to reduce the noise in the cockpit. I never used it because this stuff is like
lead in sheets. Incredibly heavy at 0.7 lb/sqft (3.4 kg/sqm), if I did the
converting right. But it looks like it is what you used. I include a picture
of what I got. It's a butyl based insulation with foil. About 80mil (2mm) thick.
Is this close (at least in thickness) to what you used?

A-51,
Does your CFD show the ideal location for the carb vents in the plenum? Should
be as close to a stagnant velocity point as possible I would guess. In my plenum
they are located about as far from the top as in yours but further outboard,
more or less in line with the carb intake axis.

That is light weight sound reduction product at 0.7 lbs sqf. If it works on the
firewall please post results.
Dad spent many thousands of hours flying in the western Canadian Arctic behind
a variety of aircraft that were rather loud but the worst was his Helio Courier
with its gear driven Lycoming G0-435 he found a good solution though with adhesive
foam & .010 lead at 6 lbs sqf. it was much heavier than the product you
have but it made the geared Lycoming seem almost silent.

Cool story. I guess that to me this stuff seems heavy. I did have a 1964 Mooney
that I removed the sound deadening material from the thin fwd fuselage aluminum
skin. It was so lout that it would overpower the ANR headset I had back then
and make it squeal during take off until power and prop RPM was brought back
a little.
I got the plenum out and will be doing the covering it today. The firewall I will
do after I take the engine out to facilitate painting. Still don't know what
to do there. I may use the "heavy" stuff I have for the metal firewall section
(mono) since I heard that part could be a big contributor to noise going into
the cabin. But may consider doing a blanket for the composite if I get some
positive feedback from the group.

Ok, an update from this morning's second test flight...
Today was magic; perfect conditions and zero wind; was up in the air just after
sunrise; and experienced even more brilliant results... Today I got to use my
TSO'd Clarity Aloft in ear comms without any bit of challenge from external noise;
they are actually better to use now than the Bose Active X; even on WOT
the Clarity Aloft volume was set at about 30%.. the aircraft flight experience
is now like cruising down the highway in a wonderful 60's british sports car...
it takes a lot to impress me, and i am beyond impressed; the aircraft is just
such a joy to be in now.
The conditions were so good today i tootled around at 70kt for 75minutes and burnt
a whopping 6Lt of fuel...
Chris, the product you pictured is the same spec, and its "Diver Consolidate Industries"
in victoria australia, google for "DCI Heat Shielding", try emailing
Wayne, he will fill you in on how to correctly use this product. For something
like a 60's mustang rear quarter you only need a 4x12 inch strip to stop the
panel drumming. There are other lighter DCI products for noise attenuation.
Regarding the compensation tube positioning; any position 1.5" toward the center
of the plenum box away from the carbi induction port will be in static atmospheric
conditions and away from induction affects.
The plenum box rests upon the top of the undercarriage spaceframe posts and backface
firewall; it could be 50kg and still not cause any stress upon the bing
carbi mounts.
As is the mod has sent hell screaming back to where it fricken came from!

Hello Europa Community:
I am looking at upgrading my existing GRT SX-200 EFIS equipped aircraft to autopilot

What would be the best practices, from lessons learned and MOD 75&76 prescribed,
to install the two lateral/vertical command GRT servos?
While the lateral component control from a servo installed under the right seat

the vertical component servo to the CS10 torque tube. MOD76 suggest complete
removal of the existing CS10 torque tube and replace with a CS10/2 version
having an actuation horn affixed to. Is this the only (difficult) solution or
would a connection to the elevator pushrod or already welded on actuation horn
be a solution, without purchasing a replacement CS10/2? Perhaps welding/ riveting
a horn to the existing CS10 tube would do?
I have the GRT servos which look very similar to Dynon or Garmin AP new digital
servos - any solutions to make a metal bracket or otherwise securely attach the
servos to the aircraft would be appreciated? GRT sells metal servo brackets
for general installations.
I have a CLASSIC fuselage with original large tunnel.
It was mentioned there could be a conflict with the glider wing brake actuating
mechanism for the vertical component of the autopilot installation. EUROPA gliders,
was there a solution found?

For treating firewall areas i would not use the butyl matting product... there
is a much lighter product in the DCI line that is a dacron weave with 3M adhesive
and foil shielding; it's primarily a medium level heat shield and acoustic
isolator for OEM automotive under roof paneling; weighs almost nothing and is
perfect for the firewall and upper engine cowl lid... it can be purchased direct
in 1000x1000 size sheets.

I used the Noico material since I already had it (purchased a while back but never
used due to the weight). and is installed. Unfortunately we have a few days
of bad weather and wind coming so may not be able to test but will try just
before sunset today if the wind dies down a little.
Regarding the material to use on the firewall, flammability of the material needs
to be considered. I did a vertical flame test on the material I used in the
airbox and the flame did not propagate. After the starting flame is removed it
will burn for a short time but not support it (quits). I don't think it is any
worse than the resin the airbox is made of but not 100% sure of course. And
even wonder if it was the adhesive that was burning. But if there is a fuel or
oil fire in the engine compartment this stuff will certainly not help. And the
fumes may be another problem. So I would not consider this material unless
more info on this becomes available.
I will do a more aggressive test later this weekend using a torch. Want to make
sure the material will not support s flame a I saw earlier today.
Here are some pictures of the install. Looking forward to testing :)

Nice job; you don't muck around!
Your airbox is slightly different and looks like your engine is possibly set forward??
Technical data on the butyl is provided on the DCI website in support pdf document;
or via emailing them. Be mindful though it is shielded by the foil so this
prevents air supporting flammability, but at the right temperature butyl will
liquify into a tar type goo. If the situation is getting that hot you will likely
be having bigger issues to worry about than the butyl igniting.
Looking forward to hearing the results...

A51,
I didn't muck around on this one because I am so desperate to see if this work
and make my airplane quieter that this morning I woke up before the sun came up
and couldn't sleep anymore so went to the hangar and got to work :)
Regarding the different airbox, my kit was a mix of bits and pieces scattered all
over the country (and world). The airbox was missing but a kind soul in England
send me an old one which is what you see here. However, when I tried to install
it the thing's size was so off that the top cowling would not fit by a
lot! I had to Frankenstein the airbox and chop about an inch of the top and glass
it all up again. So yes, it is certainly custom.

On the Europa Club website under Bud Yerly Notes, there is a document called Pitch
Autopilot Options which gives several suggestions.
About your glider question, we found the mono wheel flap pushrod interfered with
the glider spar after the spar was enlarged with the mandatory mod. Our solution
was to replace the rod with a push pull cable. We have not completed our
glider wings so no idea about interference with the airbrake mechanism.

Ahhh, that makes sense.. yes, i fitted some buffer pads under mine and had to remove

about 45min flight time i would start thinking about wanting to land and rest..
last three flights i have not had any thought about landing to rest... feeling
a lot more connected to the aircraft now.

at 90kt into a steep climb at 5000rpm holding at 72kt; watched the dial hit 1000'
in a blink, then cruised around at 75kt again... figured, hey i got nowhere
to actually go, why burn all that fuel and load everything up?! Did a few more

Hi Area-51, I follow your posts with much interest - not least because you have
a handle on the engineering physics as evidenced by your simulation images.
I was going to say that whilst adding mass coating is one route to improvement
(Bergers Law 1911), isn't a set of noise-cancelling headphones a more optimum
or at least, initial, route to achieve the same thing - and at less weight gain?.
Not a criticism, just interested to know why the additional mass route. It will
work if you add enough mass, but the carb rubber wear/unknown fire risk increase
and general weight penalty does seem a bit onerous.
That said, the tinkering/problem-solving with these things is almost as much fun
as the flying, of course !

These are great discussion points, so let's break them down a bit...
The weight penalty factor v's noise cancelling headphones:
I've added 1000g stationed 50mm ahead of the firewall; my W&B has been marginally
affected... The Bose Active X headsets weigh 0.485kg (1.1kg with carry case),
the Clarity Aloft weigh 0.135kg (0.320kg with carry case)... The AUW penalty
is now the added mass less the gain; we are now at around 0.4kg weight penalty...
but hang on a minute, let's now fly two up! Bose headsets with carry cases
2.2kg, Airbox mod with Clarity Aloft headsets and carry cases 1.75kg... just
lost 0.45kg!! ... thats two more $100 hamburgers!!

Thanks for your reply and i do understand your reasoning.
In the Automotive world (based upon ~20+ years in hands-on NVH development there),
the other issues were 1) moving the resonating cavity/intake openings as far
away as possible from the operators ear - usually to the front of the engine
bay, as, like reductions from mass damping, distance makes about the same difference
in attenuation (double the distance, halve the sound power), and 2) working
to try and tune the intake pipework so that it does not resonate at the
typical cruise engine RPM. Most cars have intake resonators that take this problem
away - some of them are even closed-loop, measuring the tone and then adjusting
the effectiveness of the anti-resonator to minimise it.
I wish we had the freedom to tinker here in the UK that you have - changing a nut
and bolt can invoke cries for the mandatory need for a scrutinised MOD required,
here.
And I dearly wish i still had access to the rather expensive test equipment i could
get my hands on back then, a Campbells diagram [Sound level or Vibration
amplitude vs both RPM and frequency scales - for both engine Vibration and emitted
noise vs RPM for e.g. a Rotax engine installation in a Europa], could tell
us all so much - why exhaust springs break so easily, why the noise in the cabin
is what it is, and what the optimum engine RPMs would be to minimise those
etc.

Flew again today; the results are very consistent.. next stage is an internal baffle

so any noise emissions would be directed out front like an air horn as apposed

As Clive alluded to, resonance in the opposed 4 banger exhaust is an issue as well
as intake. The thin fiberglass footwell directly under the feet of the pilot
or passenger, especially in the Classic with the exhaust pipe exiting directly
aft under the pilots feet, resonates something fierce and sounds just like
the carb inlet. Creighton Smith's 96EG underwent a surgery of the heavy Classic
Exhaust and the aft lobe was removed, and a straight pipe added. What a
racket that made initially. We changed the tuning length and put in an expansion
pipe (nothing sophisticated, just cut the pipe and put a wider pipe on the
end to change the note). Creighton was a motorcycle racer, and he did an excellent
job softening the sound. What a difference. Still louder than my 914
but it didn't bring the airport to a stop on ground runs any more.
Prop pressure pulses across the aircraft windscreen in the Europa are not that
bad, so I have not been concerned with that as in other light aircraft. However,
any looseness in the doors hinges, latches and the D panel in the back are
very large drum skins and the low frequency drone is annoying enough and fatiguing,
but the rattle is irritating beyond description. Prop power pulses as
I call them, is normally not bad on a three blade that is tapered. The two blade
wide chord blades can definitely be felt and heard as even the XS nose tends
to transmit some of that back to the cockpit.
Personally, having a 914 and leather interior makes most of my aircraft remarkably
quiet on the inside. The 912S and 912 versions I tend to prefer a rework
of the inlet air geometry to break up the intake noise and as far as the exhaust
note, I leave it to Robin at CKT Engineering for the 912S exhaust note. It
is amazing what a bad baffle in the exhaust sounds like. Many don't realize
they have a bad silencer baffle. CKT has done a nice, but expensive, Rotax 912
down pipe exhaust and side exit that makes the little fart can engine sound
very quiet. My opinion for what that is worth.
Noise is fatiguing. ANR helps the ears, but the vibration of the various noises
hitting the body is fatiguing. The Europa has that phenolic type firewall that
is very thick and I do not do any heat or soundproofing on it. I do add a
thin stainless steel plate some 4-6mm proud of the pilots footwell on some of
the 914s as this cuts the heat on the feet. Proper air venting is needed down
here in the South. I will not do a painted only interior because it is loud
and sound bangs around all through the cockpit with nothing to absorb it. I
do not do any firewall sound proofing on a trigear because I build in a firewall
aft of the nose gear covered with firewall 2000 (excellent fire and sound proofing).
The mono is a different animal. I find the metal firewall an excellent
sound transporter and amplifier. The airflow through the slots is also a
bugger. I have tried the soft and hard Lord mounts and frankly didn't see any
change in apparent vibration (purely measured by feel) Props make a difference
as does exhaust plumbing and support. Nothing worse than an exhaust system
in contact or firmly attached to the frame on a 912S. The 914, you don't have
a choice on the mounting. But in its 15-20 years it has had a few turbo support
cracks repaired.
One of the reasons I went with the stock kit. Experimenting to fix issues is time
consuming/expensive and well, an experiment, sometimes it works, sometimes
it doesn't and hopefully, it doesn't add weight.
Keep up the good work.

Yep, that D panel at the back of the cockpit along with its bulk head sure sounds
like a brazilian festival drum... that got attended to not that long ago by
fitting a 1/4" ply brace for the luggage ties to the reverse face of bulkhead;
made a noticeable difference.
181 has a CTK exhaust fitted and i find its performance quite acceptable; DCI SheetHot
5000 had to be fitted to the lower cowl as it was burning and getting
pretty close to igniting. The footwell area does not get that warm.
I have been receiving some pm's regarding the air box mod; its turning out a common
grievance for many other europans. Regulations in the UK may possibly be
mitigated by reviewing the mod as a "surface treatment" much like painting, as
the box itself is not being modified; just my thoughts here not recommendations
to depart from any regulations, especially any fire risk prevention regulations.

Experiments and discoveries are moving forward over the past few days with some
entertaining results.
A rudimentary study of some baffle concepts were drafted and run through the simulator;
the variations happened by accident due to forgetting to half the density
consumption to rpm speed; so the elongated porting was developed and employed
on these over calculated equations of x2 actual rpm; once recalibrated the
results were pleasing on all the variations.
Flow analysis through the air box was applied at 6000, 5500, 5000, 4000 rpm at
1013.25 atmosphere at 20.05C. Filtering for Static Pressure primarily, and Acoustic
Energy and Flow Path as added features.
Red represents Ambient Atmospheric Pressure which indicates zero restriction to
air flow within the airbox at engine rpm.
Testing revealed the carburettor porting tubes are slightly undersized causing
a pressure drop in these regions at engine speeds above 4000rpm on normally aspirated
setups. At 6000rpm the pressure drop equates to approx 600' altitude increase,
and at 5500 rpm approx 300' altitude increase, and at 5000rpm around
80' altitude increase.

Very interesting conversation guys. Part of what makes owning an Europa fun is
this type of interaction.
I have not been able to fly the airplane enough to reach a conclusion on this most
recent mod to my plane. I only flew around 20 minutes last Friday, was windy
and bumpy so had other worries in my mind. Tomorrow AM looks nice so will do
a short local before work but really want to do a longer x-country to be able
to provide an objective conclusion (on the subject of fatigue).
But I hate to report that based on that short flight last Friday I did not find
that the mod made as large a difference as I was hoping for based on A51's encouraging
results. But again, the jury is still out.
I think I do detect a slight difference. Maybe a little softer on the high frequency.
And I think it is worth keeping the change. But I was hoping for more.
Will report again after I get a few longer flights in.
Please do keep in mind that I have a paint only interior and, as Bud indicated,
I too agree this is a good reason why my Europa is loud.
Clive, I still need to go through all the tech discussion in detail (I am at work
dealing with other tech discussions) but I did buy a new Bose A 20 when I started
flying my Europa. It is incredibly effective at cutting all low frequency
noise (prop) but all the high frequency ones seem to go right through making
it VERY annoying. In fact, I sometimes switch to my non-ANR headsets and find
the low frequency drone much more pleasant (but yes, it is louder).
So I will continue evaluating and will provide some final thoughts later on. And
all feedback on this subject is greatly appreciated.
I think that if I try something in the near future it will be lighter noise insulation
on the metal firewall, some quick prototype level interior paneling to
see if I can see a change before commuting to that route, and I really wanted
to try a wheel pant I have for the mono, maybe in hopes of deflecting air away
from the wheel well and reducing turbulence in that area.

Fwiw,
Classic, mono, no fairings, panted interior, 912s, stock exhaust, factory cold
air intake plenum.
My biggliest bang was the softer lords swapout. Before with the stock rubbers the
gear whine and harsh compression pulses excited the cabin surfaces and the
engine was the most overbearing noise. Post rubbers, the gear whine is below
the engine, and the engine is below the 130mph cruise air noise. e-props unique
sound signature is more noticable than the WDs when pulling throttle back. I
doubt i would have heard that with the stock mounts. High freq engine noise is
far below the wind noise. Bose do a fantastic job now.
E-props reduced the large start stop excursions (and obvious gearbox dogging) experienced
with the WD, nullifying my previously required exhaust and oil reservoir
clearancing efforts with the softer lords.
Unhappy with bose high freq atten? Try the lightspeeds for comparison lol.
I also get a noticeable buffet from my unfared mono wheel, but havent got around
to fairing it..watching with interest if you do.

Interesting Pete,
Since I will probably be removing the engine for painting in the next couple of
weeks, does anyone have any dimensions for the new spacers needed to retrofit
the Lord mounts? I remember Erich telling me a while back that getting the engine
to rest in the correct position took a bit of effort.
I could give this a try.

to add one interesting anecdote regarding the noise in my Europa, people tell be
that when I fly overhead to enter the pattern (midfield downwind entry is common
at my airport due to a Class C at one end of the field) my airplane makes
no sound. They can only hear what they think is just wind noise and makes them
think it is an electric airplane :) Good job CKT.
But inside .... another story. Although I once took a friend up for a ride and
he thought I was crazy and that the airplane was not that noisy inside. But he
has an F1 Rocket so he may not be a good judge of what a small Rotax powered
composite airplane should sound like :)

Weather here in FL has been a bit wonky. Nice during the week and then not so good
on the weekends when I can fly. I did Area-51 mod of insulating the intake
air box with sound deadening material (enjoyed being in project mode) and waiting
for weather to improve a little to fly more.
I am getting ready to paint the airplane. I have bought a good spray gun, a forced
air respirator system, got the paint and I am rebuilding my wood frame spray
booth. I am going to wait until after Sun'n Fun next week, in case the weather
is awesome and decide to fly the airplane there, to start disassembly and
painting. I plan to take my time to paint and implement a few changes on the airplane.

Choosing not to fly today; instead thought toward identifying drumming areas of
the fuselage; details attached along with required acoustic patch sizes. Some
areas of hatches and footwell floor are only accessible for treating during building;
footwell floor void could probably be filled with expander foam though.
Total added mass can be estimated from sizings. Sizings can be reduced 20%

Shortest flight yet this morning. Rolled out on 23 after pre-flights and hit rough
as guts turbulence straight away until turning xwind at 500'... then spotted
a squall approaching at 15nm from the south. Jump plane advised about to drop
chutes.... quick decision to re-join circuit downwind and put the bird back
on the ground; squall hit the field upon exiting cockpit.
Had a random moment noticing how clear headset audio is now with the Clarity Aloft...

| Subject: | Muffler (silencer) suspension puzzle |
| From: | "JonathanMilbank" <jdmilbank(at)yahoo.co.uk> |
In my limited knowledge and experience of light aircraft having flat-four boxer
engines, particularly the Rotax 912 series, the various muffler designs have
something in common. The muffler boxes all hang by the four exhaust tubes (headers)
from the exhaust ports and this has always seemed strange to me. It hardly
seems surprising that aircraft owners get cracked tubes, broken springs and
occasionally cracks in the muffler boxes.
Before going further I want to assure anyone who might be interested that my engine
mount rubbers are good, the carburettors and propeller are balanced "to within
an inch of their lives", the muffler and tubes get installed with extreme
care not to introduce stresses by tightening the manifolds haphazardly. In fact
CKT provides a telescopically jointed #1 cylinder tube which, if installed
last before tightening the joint clamp, should ensure that there aren't any installation-induced
stresses.
Yes I've tried the alternative type of tube with the Rotax-provided header pieces
which insert into the exhaust ports and it made no difference. It cracked after
fewer hours than the older type which it replaced.
A friend has an Evektor SportStar with an identical Rotax 912 and its header tubes
look segmented, like a vacuum cleaner hose. He never has muffler related problems.
Before converting my aircraft from Classic to a more XS-type configuration forward
of the firewall, I had the original double-chambered heavy silencer provided
by Europa and it also had occasional broken springs and cracked header tubes.
Eventually I resorted to making two thick large eliptical "washers", each with
a large hole through which the lower engine mounting bolts were secured and
a small hole for attaching a bracket. These brackets, being one narrow strip
of metal each side going to the sides of the silencer, were then secure by jubilee
clips to where the tubes entered the muffler box. That put an end to broken
tubes etc for a couple of hundred hours.
Now to my question. Why are mufflers allowed to hang unsupported by their tubes
and consequently vibrate laterally. Is there a risk that by preventing some or
most of these vibrations, cracks and/or damage might occur elsewhere?
I'm hopeful of an answer from someone who has formal engineering expertise to offer,
relating to "dark arts" like harmonics, oscillations, nodes of vibration,
damping, crack prevention and all that esoteric stuff, but in terms that a layman
can understand. In summary, what are the associated risks of anchoring the
muffler box like I did previously?

Nearly all and everything contemporary produced is completely designed within a
digital computer specified environment; from electronics to mechanical; covering
design criteria such as Thermal Expansion & Conductivity, Modal Frequency
Vibrational Response, Dynamic Physical Loads & Gravity, Material Elasticity Stress
& Strain, Chemical Interactions... This is a very basic matrix of R&D analysis.
When a company such as Bombardier develop a power train it is run through the above
matrix before being produced and released for industry use.
The factory supplied 9XX exhaust system will have the above matrix applied along
with field testing results which are fed back into the design process upon a
"Continual Improvement" basis, which the end user sees as optional or mandatory
factory Service Bulletins.
This closed loop system quickly falls apart when third party aftermarket components
are brought into the mix; some may cause premature failure, others may prevent
it; it depends upon the applied knowledge of who ever is producing the component.
The whole exhaust is constantly vibrating at (x)hz at (x)deg and will be tested
at the factory based upon the typical operating ranges of the power unit being
in the vicinity of 5100rpm and (x)deg give or take 15% either side. Stress and
strain fatigue points of the exhaust system will naturally be found around
both bending points, and attachment points. Hard mounting the exhaust muffler
to the engine block moves any inertia forces of the exhaust into the engine block
which may or may not be designed to support such loads beyond (x)hrs of usage
at (x)rpm.
A rough running engine or loose fixing somewhere in the mix adds another dimension
of vibration into the fatigue failure equation.
This why its important to keep any motor well serviced and tuned and running smooth.
The short answer to the question is "Cycle Count" but that is just going to be
too cryptic for most to understand.

Today is Sunday and the conditions are useless again for flying.
So its back into "Shut That Noise Up" project...
In this post 181's air box is getting analysed for harmonic resonance. The test
passes frequencies from 1hz to 20,000hz through the 1.5mm fibreglass component
to see where points of dynamic distortion will be at specific frequencies; blue
is zero red is maximum.
Four frequencies were isolated from the pack to review what is going on at 3600
/ 4000 / 5200 / 5600 rpm. The data provided correlates to where the air box body
is "resonating" at specific rpm. The purpose of this is to identify focused
points of resonance that can be individually attenuated as opposed to wrapping
the entire box.... image order correlates to rpm list above.

or in my case a pocketed dog gearbox, heavy warpdrive prop, eaten plastic gearbox

Today I finally had a chance to get a longer flight in. It's hard to say how much
improvement the install of the sound deadening material on the air box has
on the internal noise. But there is certainly improvement!! The flight today was
very pleasant and more enjoyable. But what really struck me is that, as A51
experienced, I had to lower the intercom volume quite a bit since it felt too
loud. Same thing when I was playing music as I generally do. So, even though
I can still hear relatively high frequency sound, but maybe less, it seems that
overall there is a reduction in noise.
But, I have to admit this is all just based on perception. It is indeed hard to
quantify the change. But I have to say that despite the increase in weight, it
is a keeper.
On a different note: I finished rebuilding my spray booth and getting closer to
starting the painting process. I will hold off taking the airplane apart this
week to see if I fly it to Sun n Fun but by next weekend it will come apart so
no more flying until it is done. I also have a couple of pending jobs I want
to perform on the airframe.

Dear Europa Friends,
Since my airplane is coming apart for painting, I wanted to implement the cockpit
widening mod 67. Any negative experiences with doing this? I think it would
help increase the comfort of the airplane as I notice that after a x-country
flight my left arm hurts a little from rubbing on the door frame.
Since the door will be worked on I am going to change the gas strut attach point
(my door was already built with the old style attach point). I know this is
basically a must although the current configuration has worked OK.
At last, anyone has any experience with installing a monowheel wheel pant? I have
a kit for that and was thinking about installing the front part only. I am
not doing it for the speed as I know the wheel is basically blocked by the cowling's
exhaust but I think it could help seal the wheel well better and possibly
reduce turbulent air getting into it (noise).

Attached is a rudimentary cross section of free stream air through the forward

>From experience flying in a mono with wheel fairing fitted; with ANR switched
on at the time there was no detectible change in cabin noise volume compared to
flying in 181. However the degree off air flow through the cockpit was greatly
multiplied due to the wheel well being mostly sealed off during flight; not
fitting the rear portion of the fairing will greatly diminish this ventilation
feature.

to flying in 181. However the degree off air flow through the cockpit was greatly
multiplied due to the wheel well being mostly sealed off during flight; not
fitting the rear portion of the fairing will greatly diminish this ventilation
feature.

Sun 'n Fun is here! Join us at the Forum!
Now that Anita and I are no longer doing a booth at Sun 'n Fun, my blood pressure
is down, and my sense of humor is back. Airshows can be a grind. We are volunteers
for the event with my local EAA chapter making sandwiches daily with
about 40 other volunteers and friends from the local community and our flying
community.
Jerry Hope and I and our wives are at the Sun 'n Fun Pavillion making sandwiches,
drinks and shooting the bull from 0900 until 1130 daily. So far, Anita and
I enjoy driving home after lunch and I go to the shop and print some 3D mods
and repair parts I have done to tools/and other items. I have made many little
tidbits improving my aged CAD skills and patience as these printers are notoriously
slow. Frankly, some of what I have done could be whacked out of foam
and glass and modded quicker. That's another story.
If you all would like to come and chat, we have a place to meet out of the sun
and a bit more quiet, so come over to the pavillion about 1130, it is a nice place
to meet and exchange ideas. I will be walking the show in the afternoons
taking a break from the airshow watching crowds seeing the sites and old friends
and if anyone wants to go to the shop in the late afternoon, I'll be available
to open it up and assist folks wanting to sift through the mono stuff left
over. In the shop, I only have one kit left partially built XS Trigear and
Brett Browns trigear and my own trigear. Of course, I'm tearing down my woodworking
tools and rehabbing them so it is a mess. That is where the 3D printed
parts are going.
We've arranged a Forum for Europa Owners on Wednesday March 29th at CFAA-05 FROM
1:00 TO 1:55 (the Nazis will throw us out at 1156). There are problems that
just arrived with WiFi in the building so this will be an informal gathering
for Europa Owners and the topics are open for discussion. Of course, we also
can meet in the Sun 'n Fun Pavillion area daily and gather and talk about individual
issues you may be having on your Europa if you don't want to discuss it
in the forum.
I have a shopping list this year and am not afraid to exercise it, so 12AY is tore
down in the shop getting little goodies installed. I may be adding the internal
Stratus to my ESG transponder. Some other doo dads are being looked at
and more than likely I'll probably just build another Stratux an put it into
the cockpit area. My move of the Stratux ADS-B in to the rear near my transmitter
antenna has caused interference with the ADS-B operation and although shielded
and working, it looks like an amateur did the install.
The weather looks reasonable from Tuesday afternoon through the rest of the week
so join us. Be sure to bring sun screen and a hat. IT IS HOT!
Best Regards,
Bud and Anita Yerly

| From: | "Area-51" <goldsteinindustrial(at)gmail.com> |
Today has been spent crunching numbers again by adding the butyl layer to 181's
air box. The untreated air box was also rerun through the same analysis matrix
settings as a control for comparison purposes.
Several criteria were examined on both models; the modal natural frequency, the
harmonic response, and the harmonic acoustic qualities.
Two sets of solutions were applied overall based upon 1 cylinder cycle and 4 cylinder
cycles from 3000rpm to 5800rpm; both provided similar attenuation plot
results. The images attached are from the 4 cylinder cycle solutions.
The attached images relate to distortion of the air box at a nominated frequency
of 8200hz, being 4100rpm. Blue represents zero distortion, red maximum measured
distortion. The two images clearly show how well the butyl layer attenuates
excitation frequencies of the air box; being the image with the most blue.
The attached graphs are related to the amplitude of applied frequencies being projected
from the air box to the surrounding environment, measured at a near field
specific position to the air box being 100mm above the air filter opening,
behind the rear at the firewall, inside under the air filter, and corollate
to (x2) rpm.
The db attenuation qualities of applying the butyl has proven much better than
expected. One point to note is the material density applied. The DCI product presents
a density of 1310kg/m3 against standard 900kg/m3 of other similar products.
It was surprising to make the distinction between the lower amplitude levels on
the graphs to the different power setting rpm selected in real flight situations;
they are identical to where the smooth running points are being perceived
to be.
Again these tests are not for determining induction noise affects, they are for
determining the inherent acoustic qualities of the air box and how it is affected
by environmental frequencies along with its ability to adsorb vibrational
frequencies. Can it or can it not absorb and dissipate a specific kind of kinetic
energy.

Air spilled from the intake duct looks terrible.
I also have the duct open on the lower starboard side of the cowling. I guess that
is there for the 914 but I kept it open because it seems to provide some cool
air to the oil tank area and rear of the engine. I dare to say it may even
augment the flow through the exit a little. My cooling system is working very
well so afraid to change anything at this point.
I am planning to remove the gills on the top cowling and make that area smooth.
I have them closed right now and it seems to me they probably just add turbulence
to the air going over them.

BTW, I did a little number crunching of my own. I measured all the templates I
used to cut the airbox sound deadening material and calculated the weight for
the Noico material I used.
0.6 kg or 1.3 lbs. It is significant for a single component but for now I'll keep
it.
Regarding the effect of this additional mass on the carburetor mounts, the airbox
is well supported on the back. But that's not to say it has no effect on the
carb rubber mounts so I will just double the inspections on that area.

| From: | "Area-51" <goldsteinindustrial(at)gmail.com> |
[quote="n7188u"]Today I finally had a chance to get a longer flight in. It's hard
to say how much improvement the install of the sound deadening material on
the air box has on the internal noise. But there is certainly improvement!! The
flight today was very pleasant and more enjoyable. But what really struck me
is that, as A51 experienced, I had to lower the intercom volume quite a bit since
it felt too loud. Same thing when I was playing music as I generally do.
So, even though I can still hear relatively high frequency sound, but maybe less,
it seems that overall there is a reduction in noise.
But, I have to admit this is all just based on perception. It is indeed hard to
quantify the change. But I have to say that despite the increase in weight, it
is a keeper.
On a different note: I finished rebuilding my spray booth and getting closer to
starting the painting process. I will hold off taking the airplane apart this
week to see if I fly it to Sun n Fun but by next weekend it will come apart so
no more flying until it is done. I also have a couple of pending jobs I want
to perform on the airframe.
Chris[/quote]
Chris, i noticed you mention calc on the added mass of your air box being 0.6kg.
This aligns with the lower density of products out there. The affects will be
reduced... Adding a second layer will bring the results closer to what the DCI
product has provided, but will of course add another 0.6kg.
Reviewing the graphs demonstrates the db reduction achievable for a given rpm.
The average is 10db but some points it is as much as 25db... the high frequency
vibrational load upon the carbi rubbers is reduced as well as a result.

| From: | "n7188u" <chmgarb(at)gmail.com> |
Hi,
As I mentioned on a previous message, I am considering the cockpit widening mod
(67). Just checkng to make sure it makes sense since it involves some cutting
and will require me to touch up the interior paint which is quite nice right
now.
My concern is that the mod involves only a partial widening of the lower door edge.
It seems that if you do this your arm will still touch this remaining edge
of the door. I guess that yes, that remaining width of the door is further outboard
than the fuselage door flange so some gain in overall width is achieved.
Im looking for some comments regarding this mod. Impression? Are you happy or not
if you did it? Is it worth it?
I once asked Bud and he gave his nod of approval which to me means a lot. Just
wanted to see what other people that have done it to their airplanes thought.

Hi Chris
I have done the width mod and to be honest it's a waste of time and effort. It
buys you no more than 15mm on either side and requires you to cut out a chunk
of the fuselage door lip and well as doing the same with the door, as well as
reworking the door locking mechanism. I'd leave it personally.

Chris, my aircraft has this mod already done so I didn't know any better but recently
I rode in one without it and I can say that I noticed the difference. It
wasn't a remarkable difference but was noticeable.
I suppose that this comment just muddies the waters for you as I'm sure you will
get the opposite view.
Why don't you try to sit in one that has the mod first and decide then?

The downward curvature of the canopy prevents sitting close to the door and forces
the occupant towards the centreline of the aircraft.
So, providing hip space in the centre tunnel is more effective that arm/shoulder
space at the door.
However, if you are sitting low with good head clearance then it can make a difference,
if only to make it less noticeable that the door cill is sticking in
to your arm.

Hi guys,
Thanks for the feedback. Very much appreciated. I still have some time before I
need to commit because I will leave the painting of the fuselage to last.
Although it doesn't look hard to do I agree it is quite a bit of work. Particularly
considering I already have the interior painted and would require sanding
off the paint in the areas needed, and then paint it again.
I will say that at the last flight I did the contact of my arm against the door
sill was bothering me a little. I also think that the continuous slight leaning
to the side doesn't add to comfort. But as Duncan said, the head is also an
issue that is not addressed my this modification.
And I am not really a wide person. I wonder what demographics Europa had in mind
when they designed our beloved airplanes [Rolling Eyes]

| Subject: | Re: Finishing tips |
| From: | "n7188u" <chmgarb(at)gmail.com> |
One personal observation regarding finishing:
I thought this process was going to be painful, but actually found it to be not
as bad as I thought it would. I honestly did not read the entire procedure posted
here but I will briefly say what I did.
1.- Clean and carefully scuff sand the fiberglass or gelcoat.
2.- Using the the fishing line technique, apply a nice think coat of expancell
plus West Systems 105. What helped a lot was to use an epoxy pump and a sensitive
weight scale to exactly measure the ratio of epoxy and expancell. Keeping
the mixture consistent between mixes is key.
3.- Apply the mix using a dry wall spreader modified with an angle epoxied at
the width of the application end. This is also key to keep the spreader from bending
and creating a concave surface.
4.- Wait until the applied coat starts to gel, remove the fishing line, fill the
groves left by the line.
5.- Using Dura-Block sanding blocks and very coarse sandpaper sand expancell coat
until no depressions are observed. Most of the time a single pass of expancell
coat was enough. If a few voids are present fix those.
6.- Now the cool part, I used a modified epoxy 2K filling primer made by 5-Star
and rolled it on using a small foam roller. Push hard and fill as many pinholes
as you can.
7.- Once cured, apply coat of Dry Guide Coat (I used Mirka brand).
8.- Sand this coat until all of the guidecoat is gone. Don't worry if this results
in a good part of the 5-Start 2K to be gone.
9.- Spray one heavy coat of SPI (Southern Polyurethanes) white Epoxy primer. Welcome
to pinhole land since this primer will make them show like craters in the
moon (it's actually called "cratering" by the people that make the prime which
is very prone to doing this).
9.- Now, without sanding the epoxy primer but before 7 days after applying it,
use thin 3M polyester glaze to fill every pin hole, one by one. This is tedious
but the fantastic quality of the 3M glaze makes the job much easier. The 7
day window is important since the epoxy primer doesn't need to be sanded if the
glaze and subsequent 2K is applied within this time frame.
10.- Sand the pinholes. This part is indeed tedious because the polyester putty
will stick to the sandpaper. The solution was to use a scrap piece of fiberglass
and use it to scrape the glaze of the sandpaper. Use only high quality 3M
sanding paper. The cheaper red one seems to work better though and the glaze sticks
less.
11.- Spray a heavy coat of SPI grey regular 2K primer.
12.- If any small pinholes show I used red one part lacquer glaze to fill them.
Quicker and easier for just a few of them.
13.- Guide coat, sand until the white shows and almost all grey 2K is gone. the
guide coat will show the low spots. Here you need to gage what fillers to use
to reach perfection. A little more 2K will fill shallow areas but it is a little
heavier. Still I used it. Some polyester 2K glaze is also good. I don't think
I had anything deep enough to go to expancell. If you do you have to do all
the stuff stated above on that area.
14.- Finally, a coat of SPI white epoxy and you can spray the paint (no sanding
needed if within 7 days). Or I flew it on primer for 2 years. The stuff still
looks like the day it was applied and no issues with bugs or deterioration. The
SPI primer is semi gloss so it looks pretty good too.
And I used a forced air respiration system and a dust collector from Harbor Freight.
I think it is a must.
I can provide more detail on the sandpaper used, 3M glaze PN, 5 Star modified epoxy
primer, SPI stuff but will have to collect the info. I can also put together
a few pictures.
I hope I didn't bore anyone with this long post.

First Day of Sun 'n Fun.
It was wildly busy doing volunteer work. I went through the LSA and Spot Landing
contest. My old friend and EAA member John Moody (The father of Ultralights)
porpoised his little ultralight yesterday and luckily at 80+ he got a scratch
on his arm and cracked his helmet when he hit hard on the nose and the plane
flipped upside down (it is a biplane) and we got him medical attention and he
is fine. It P.O.ed his wife as he broke his pledge to stop flying his Easy
Riser. So I didn't see much and after running errands also, we got home had supper
and I'm vegging out.
Tomorrow the front comes through and we are doing the Europa Seminar at 1 PM still
showing at CFAA-05 on the second floor room 206 so watch the signs.
Fly/Drive Safe and see you there.

Im glad to hear John is ok. I always enjoyed watching his show.
Now it seems Ill go to SnF on Saturday. Not a fan of going that day but my son
has school obligations and he wants to come.
We would like to see the night show and pitch a tent to sleep then head back home
on Sunday. Ill try to fly the Europa but forecast calls for a windy day on
Sunday. Will see as the day nears. Could always take the LongEZ (that plane doesnt
mind windy days but cant take anything in it)
Anyone there with an Europa on Saturday?

| Subject: | Re: the Obsidian Files - So Much Noise!!! |
| From: | "Area-51" <goldsteinindustrial(at)gmail.com> |
Always onwards into the realm of investigation and dissection... "trust the science"!!!!
Ever wondered what's inside a 912's factory Rotax muffler?
Today's episode of "shut that noise up" was spent looking at the back end of the
rotax; running the numbers on the factory stock 912is exhaust muffler... how
well does it actually look on paper?
Well, let's tear it apart and find out?!
Thankfully no destructive work was required; and no animals were harmed in this
episode.. these days we can simply grab a CAD model and whiz it through some
predefined plugins and see what gets spat out... personally when i first turned
the cad viewer to xray i was astounded, i said to myself "that is a joke; that
won't be doing a bloody thing... what's the replacement price on that again?!"...
let's come back to that knee jerk assumption later...
So we ran our pre calc's, established our base frequency range for 5000rpm, and
got to work preping the model for analysis.
Several tests were run looking at low band, medium band, and wide band results;
the focus here is primarily on the low band results.
Well, the low band results showed zero attenuation of sound transmission until
320Hz with awesome attenuation capabilities of 32db at 460Hz!!! This is great!!
Only problem being 460Hz equates to 12600rpm, and 320Hz equates to 9600rpm
so my knee jerk assumption appears supported.
So the factory 912is muffler is as affective as that of a Chonda generator, i.e,
empty expansion box with pipe going in and pipe going out...
To be fair the muffler does provide affective mid range attenuation in the frequency
range most noticeable for human hearing, which is mostly the higher frequencies
being generated by the muffler itself.
It would be great to compare a CTK muffler but i won't be cutting 181's unit apart
any time soon to CAD it up.

An update on yesterday's recon into an exhaust muffler... spent the day trying
a few different things mods; all that was mostly achieved was a transposition
along the frequency band but not much db reduction... gave up for now and went
back to testing the carbi box... and...
Well as expected 181's stock factory air box did pretty much zip to shut things
up; on average about 3db across the whole range. Then the Mod box got some scrutiny.
Mod box rocks... on average around 25db to 40db reduction through the target range;
WOT rpm primary frequencies are returning up around 30db and secondary harmonic
ranges are returning around 15db reduction.
Will have to build this Mod box and see if the actuals match!
A 25db noise reduction from the engine will make eating cheese inflight more enjoyable
again.

Loving your posts on this topic, a great mix of detail and humour. Can i ask where
you get your geometry from - do you use a 3D scanner? And which CAD and
CAE analysis tools please?
On the potential to improve exhaust silencer re-radiated noise, i worked with the
owner of CKT a few years ago to help him develop a cabin heater based on a
shroud around the silencer (loads of heat power there). It didn't progess to
a for sale product for internal reasons, but i know them fairly well/they might
let me have redacted CAD geometry for it that might help what you are doing?
Reducing the noise radiated from the cylindrical silencer is always going to be
difficult. The flatter ends are a possible area. Think Rayleigh pistons - where
noise radiation is concerned as the size and stiffness of the surface controls
both frequency range and ability to re-radiate.

Thanks Clive,
Most of the CAD is reverse engineered; the europa is an OCD paradise.
Open Foam is open source and great for people that want access to physics analysis,
but if you can learn the other industrial commercial level packages thats
great too; same same results... Blender has just upgraded to a full CAD capability;
another free open source package... after a while they all taste like chicken
to me though.
Not a fan of and never have been one for exhaust affected cabin heating; always
ends in sudden death. Recipe for disaster and up there on the top shelf for a
Darwin Award. It needs a separation medium layer to be even remotely considered
as an option. And with a rotax why even bother, just run it off the coolant
system.
The CKT kit i can probably work out internals by tapping around with a spanner;
but if someone want to through a CAD model at me i'll give it a whirl.. exhaust
is a bit more tricky due to hot gasses cooling rapidly, so speed of sound is
transitioning from x to y to z; so not that straight forward designing on paper
or computer...

Stepping a bit over the line me thinks with the Darwin Award and always bit. Other
flying risks outrank the subject by factors.
Exhaust cabin heating can be done safely, with careful inspection and inflight
monitoring- especially with the stainless construction. In fact, my classics
cabin CO levels are determined not by the heat channels but instead by the outlet
position of the stock exhaust (I extended it), in combination with flap position,
speed, cabin vent/heat pressurization and the europas open fuse flap slots
in a high pressure zone.

| From: | "budyerly(at)msn.com" <budyerly(at)msn.com> |
The latest from Sun 'n Fun 2023
It's really nice weather this week. A bit breezy, but clear skies, and delightfully
warm (HOT to many) and well attended by fliers and the public.
Wednesday folks finally started to fly in as the weather fronts abated by Tuesday
up north. It was a huge fly in day filling most of the GA Camping area and
some in the homebuilt camping.
Wednesday Fred Klein, Jerry Hope, Lyle Antieu, Jim, and I all discussed Fred's
accident with the rocker switches having been inadvertently switched off and unnoticed.
I was asked to do a critique of Fred's switches and his fix to put
guards on his ignition, and engine control switches. A smart move on his part.
These small rocker switches are neat, but difficult to see if they are on and
off as they are a very low profile.
Fred's repairs are nearly complete and the engine undamaged so a bit more time
and he'll be flying again.
My only comment for Fred was to replace rockers with lever lock switches that
cannot be inadvertently shut off by simply hitting them.
In my previous military and civil training our instructors always required a blindfold
cockpit check prior to solo. Knowledge by wrote memory and feel sharpens
the quick reactions of a pilot. I'm a fan of it, but in the civil training
environment normally, it is not even a training that is considered. I find
it speeds checklist operations and assists in emergencies and normal ops such
as running out of gas in the main side or aux, night flying, and old guy mental
fog.
As I said, the Sun 'n Fun GA fly in side has been very well attended but homebuilt
camping is only about 1/2 full on Wednesday and another 20 or so flew in on
Thursday.
John Wigney flew his beautiful Europa Mono in on Wednesday afternoon. He reports
the new homebuilt camping area, near the VOR was quite nice and his comment
that there were only two showers for men and two for women meant a bit of patience
was needed in the AM. However, the campground hosts were doing evening
meals and morning light breakfast which John said was very nice. The only drawback
I saw was the tram for transportation to and from the area was a bit annoying
as it ran about every 20 minutes but occasionally was longer. It is a long
walk from the VOR to the airshow East End and a reliable tram was now needed.
John walked the 1/4 mile in short time from the LSA area and there were numerous
carts stopping to pick folks up from the ultralight/LSA area to homebuilt
camping.
I saw Chuck Reinas's trigear, but did not run into Chuck.
It was not as hot on Thursday, but Anita's foot was sore, my back got twisted up
stepping off a sidewalk, so after doing some volunteer work in the AM and some
Airmaster Sale visits, we went home a bit early at 2 PM. I got a well needed
nap in the afternoon, and corrected my back and Anita got her foot taken care
of. A win-win for us.
Jerry Hope leaves Saturday and I think many others will from the homebuilt area
as another front is crossing the Ohio valley area. Florida will be unaffected
but those flying home East of Ohio will be heading out I'm sure with a healthy
tail wind for a change.
Saturday, Anita and I have grand baby visits in Orlando, and we will be away from
the show for the day, but back Sunday to volunteer/assist and staying through
the teardown.
Best Regards,
Bud and Anita Yerly

| Subject: | Canopy ball stud |
| From: | "JonathanMilbank" <jdmilbank(at)yahoo.co.uk> |
Does anyone know the dimensions of the canopy ball studs, please? What is the thread
and the diameter of the ball ? Here are links to suppliers:
https://www.ebay.co.uk/itm/112402496613?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=cIQwD279Q8a&sssrc=2349624&ssuid=dW2b1pNUSLS&var=&widget_ver=artemis&media=COPY
https://www.sgs-engineering.com/gas-struts/end-fixings/ball-extensions
I've fitted new gas struts which are proving sticky / jerky when opening the canopies
a little, then become smoother when the canopy opens wider. A threaded
end has broken off one ball stud and I'm loathe to unscrew another in order to
make measurement of the thread.
Hopefully the gas struts will become smoother in operation with the passage of
time.

Most gas struts will have a C strap clip at each end (some have a wire spring clip);
extend the strut all the way and remove the clip; the socket will come away
from the ball.
Give the shaft a light coating of silicone grease to affect smooth op.

Hi Jonathan
Ends up I have a spare ball stud and just measured it for you.
A little difficult, I measured across threads and got .186". A 10-32 die wouldn't
go on by hand.I tried a 5 x .8mm tap into the nut and it wouldn't go in?
OK got it figured. The threads are 10-32. They plated after they ran a die on them.
I ran die on threads and just a tad of plating came off.
So:
** The threads are 10-32
The length of threaded portion is .390" with a rounded tip
There is a shoulder on the .390" which is .394" diameter and ~.062" long which
isn'tthreaded
Where you grab with a wrench (circle with 2 flats) has the circle diameter at
.312" and the flats .270" (7mm)
** The ball is .314" in diameter
Hope that helps
Ron P.

Hello everyone, I am in the midst of converting my mono to a tri gear.
The manual talks about installing the legs and then proceeding with the

Is there any reason why I cannot assemble all of the wheel & brake

Episode 82 of "shut that noise up"
Upon the eve of Easter, while out looking out over the distant full moon lit pastures
for a pink and white rabbit an idea emerged instead...
With feverish reckless abandon i quickly searched through some 12,000 images of
my electronic memory and found photos of 181's CKT exhaust.
Rushing back to the table with assumptions in mind the computer was turned on and
the images again reviewed,.. using the burn markings of the CKT muffler a model
of what could possibly be a similar internal structure, three absorber sections
with a central expansion chamber, was modelled and then sent through the
acoustic analyser with results being spat out shortly after.
What was found??? The CKT absorber/reflector style muffler provided better overall
attenuation than the factory Rotax reflector style unit; broader low range,
medium, and high range attenuation.
On a broadband level the CKT styled unit provided on average 4db greater attenuation
than the Rotax. Low range was shown to be affective from 50Hz upwards where
as the Rotax offers none until 320Hz. Peak attenuation levels on the CKT styled
unit happened between 2000Hz and 3200Hz where the Rotax is 450Hz to 4000Hz
with most attenuation taking place within this band.
So the CKT style Absorber/Reflector muffler is more quiet on a broadband basis
and works best at attenuating more mid-field frequencies than the factory Rotax
unit.
Happy Easter to all...

Hi Paul
You need to set up the correct angle of the legs using the spindle as a gui
de. If you have the wheel and brake on it you won't be able to get the corr
ect alignment.
The legs only bolt into the socket so once the socket is set up you can rem
ove the leg and build up on the bench if you prefer.
Cheers
Kind Regards

Hi all,
I=99m at the stage in my tri gear conversion where I need to think ab
out how
I am going to cover the hole in the belly and I am looking for ideas from
those who have gone before me. Think light =F0=9F=98=84
My initial thought is to cut some 3 mm foam and cover it with some plies of
uni on each side. I would have a couple of access holes or perhaps one oval
shaped hole.
Any suggestions would be appreciated.

Hello Paul,
Well I recently closed in my mono hole and followed instructions that Bud
posted (or emailed me, can't remember). I started by doing 3 layers of
bi-direction cloth on a glass table and used a vacuum bag to make it flat
as possible. Then taped that up against the bottom and traced out the hole
from the inside. Then I used G10 board as the access cover plate and cut
that shape plus an extra 5mm or so. From there I freeCAD designed some
spacers to give a nice even 2mm gap around the access G10 cover and placed
that in the hole and filled the void with flox and over lapped with 3
layers of bid to mount nut plates to later. With the trace line cut I held
the patch in place with tape and ran 3 layers of bid from the panel to the
side walls to glue in.
Its now complete but I have a video that talks a little about it here.

Hope this helps,

| Subject: | The Obsidian File - Mono Wheel Fairing |
| From: | "Area-51" <goldsteinindustrial(at)gmail.com> |
The second black op Obsidian File has been sanctioned for declassification...
techniques rumored used for original data extraction have been dispelled however
some information remain redacted... some names have been changed to protect
operatives still active within current high level field ops.
A quick review of data within this file focuses upon the debated myth and legend
of the Europa Mono wheel fairing... preliminary assessment of the facts shrouding
this vicarious circle of assumptions points towards the successful mitigation
of noise and turbulence; however the studies reviewed so far are just loose
preliminary tasks used to verify test field integrity.
The attached images show Acoustic Power "noise levels", and the first image Velocity
"air movement"... higher resolution and longer solution solving iterations
will provided more clarity toward actuals; bit what has been revealed so far
is useful and indicative toward a standard equipped mono.

Today was spent raising the resolution of the analysis and re-running the preliminary
solution... Some points of interest were glanced over also being static
pressure inside the engine cowl, flow velocity through various airframe vents
and openings...
Regarding the main gear area... as the images show, with the gear retracted and
set at its operational position, due to the existing lower cowl faring, it remains
just on the cusp of free-stream air during flight; however, about 80db of
noise is being displayed downstream; whether this is caused by the wheel or
the cowl faring is not yet determined... some updated images attached.
The areas responsible where most noise is generated are the flap tube ports in
the fuselage; somewhere in the order of 90db. However this may alter with the
wings installed.
Next session will be looking at same results while utilising a wheel faring.

We are in the midst of the install of our replacement 914. Europa supplies a coolant
hose for the inlet to the coolant pump that has a 90 degree bend and a 180
degree bend in order to have the pump inlet facing to port.
But the inlet can be rotated to face starboard. Is there is reason not to use a
shorter, simpler hose that would just be a 90 degree bend to go to the coolant
radiator?

I had to replace the 180 degree hose to the radiator and did it with a 90 degree
silicone hose. I inserted a coil spring inside to keep it from collapsing and
has worked well for 4 years now. You can find the spring at McMaster Carr and
it works great for tight bends on silicone hoses.

Hello everyone,

need to know the thickness of the nylon friction plate, the size of the
hole and the O ring thickness.
My guess is 1/8" thickness of the material with a 1 1/8" hole and a 1" ID O

If anyone can help I'd appreciate the information.

Not quite Paul.
NG05 is 3.00 IN OD, 1.0 IN ID, PIN HOLE 1/4 IN Centered between ID , and OD
edges or 0.5 inches from the edge. ABS plastic. I would machine from FRP
G10 of 1/8 inch thick. Easy to do on a drill press. Buy the FRP, 3" Hole
saw has to be 3" ID so I use a 3 1/8 OD instrument hole saw. CLOSE ENOUGH
.
The O-ring depends on your depth cut of the steel spacer defining the O rin
g recess.
Ideal O ring is 1/8 inch thick. 1 inch ID, 1 1/8 OD. SOME are in need of a
3/16 thick Oring with ID of 1" to seal properly due to builder tolerances
in modifying the original non sealed base. This was a cut and file mod .
Some cut the bearings, others the steel to preserve the bushing thickness.
Idea was to prevent grease from running out on the plate. That leaky grea
se decreased friction and was a continuing shimmy issue. Seal the base and
life is good.
Make sure the spindle is square to the yoke.

| From: | "Area-51" <goldsteinindustrial(at)gmail.com> |
The past weekend has not been good for flying; so more numbers were crunched and
more fairings were assessed; it was interesting to try some known shapes, no
shapes, different retraction heights, and an initial design developed way back
near the beginning of all this.
As usual the control piece was the standard mono in standard flight configuration
at 100kt velocity (51m/sec). The airframe was stripped back to fuselage only
to reduce computer power and solving time. Several indicators were implemented,
Drag, Lift, Surface Velocity, Surface Acoustic Power... Fairings were tried
as semi and fully enclosed scenarios.
What the computer said...
The standard mono wheel, when retracted, skips on its tyre upon free stream air;
most all the remaining tyre remains within a protected pocket created by the
lower cowl deflector covering the muffler... employing a fairing does little
to reduce drag, however it does reduce acoustic noise within the undercarriage
well... a fully sealed fairing reduces this acoustic noise to near zero... the
variance upon drag factor between no fairing and fully enclosed is about 1kg
out of 38kg total; Lift variance is 1.8kg less with a fairing out of 7.8kg total
and is probably due to the tyre skipping on the free stream air... and thats
about it for the mono wheel faring with the ball ended enclosed shape providing
the best aerodynamic results.
Myth Busted...
Attached images relate to velocity and acoustic comparisons.

Different from noise, i notice significant (and irritating to me lol) buffeting
starting at 120knots and increasing slightly as speed increases.
Intuitively, buffeting energy would be draggy with the pressure waves traveling
outward from the tunnel.

Consider also the gap between the frame/wheel and fuselage opening. That g
ap has to be cut "like Goldilocks" or just right or air swirls around and g
ushes up into the well.
NACA had tests on the partially retracted gear and frankly, a half-buried t
ire is a good compromise. Drag was decreased slightly in the wind tunnel w
ith a narrower gap. In these tests the gap was closed up to the tire and t
he tire gap was as small as practical. Photos are grainy and virtually imp
ossible to find from NASA. Heinkel did work in this area also.
Most 1930-40s aircraft with partially exposed wheels did hide the wheels in
the nacelles or made covers for the gap in the wings back to the tire to c
lean up the gap and reduce drag. Making a flange with rounded edge in the
rear of the wheel well area was also done to clean up the exit and prevent
air pressure buildup in the well. ( As done by Seversky in the P-35) Dougl
ass put the oil cooler on the C-47 just before the tire to cut the drag. C
rude but effective. Bellanca did no streamlining until the Viking series.
Adding a small cover to the front helped, so they made a complete door to
enclose the gear. A full fairing is nice, but the extra weight and complex
ity becomes tedious to complete effectively. Many folks up north simply re
moved the rear door.
See NACA Report 518 for some drag numbers (very crude stuff, drag is in pou
nds, but the tire size is familiar looking) to bounce off your calcs.
Enjoy your computer work. I=92m doing 3D printing stuff and cooling airflo
w and enclosure mods using similar programs. The learning curve was and st
ill is steep. Too many assumptions have to be made to compromise on airflo
w and pressure build up. Yuck. It is a hit and miss (for me anyway) on ge
tting the best airflow bang for the buck and time.

Bud Yerly

Thanks for the input there Bud; always thought provoking..
Gaps and edges can be noise generators. The semi enclosed fairing has a large gap
at the rear to allow tyre passing. On something like the europa installing
bristle brushes at the gaps might offer an affective cheap and light solution
here.
Cooling ducts on 3D printers are a real challenge. I did one a few years back as
i wasnt happy with the factory side flow versions; so i designed up a really
affective single head unit which resulted in a 150g lighter print head; took
five assumptions to get the flow balance correct... works great! Let me know if
you are interested, can send you the STL file, ready to print.

Breakfast today has turned into brunch as all three model variations had a higher
velocity of 75m/sec (150kt) applied; and revealed an interesting anomaly.
Its not certain or being ruled out that at the higher air speed an acoustic pressure
wave is detected traveling rearward along the fuselage belly aft of the
main gear. (the fully enclosed fairing does not exhibit this trait).
Other results on the acoustic aspect shows db levels increasing some 50%; the loudest
areas being where deflected free stream air at the lower engine cowl fairing
rejoins slower moving air exiting the engine bay area; some 105db; quite
audible over everything... installing a trailing fence may reduce this turbulent
corridor.
The pressure wave though is interesting, at 70-80db it would be noticeable and
the cause of it would likely be related to the flutter of turbulence created by
air passing over and behind the cylindrical shape of the tyre. As Bud mentions
above there is also the added element of air escaping the gaps of the fairing
and exposed main gear rejoining faster moving air... The belly of the fuselage
is quite flexible and is likely oscillating enough to cause annoying pressure
pulses within the cockpit.
Employing fairing fences might provide an answer to the above situation.
Regarding Drag and Lift comparatives at 150kt, standard and semi enclosed setups
were identical in Drag with the later giving up 3.0kg of Lift; again the tyre
is removed from the free stream... The fully enclosed setup provides some 3.0kg
Drag reduction and gives up 2.0kg of Lift.

Brunch has turned into lunch..
The fence concept has provided value by reducing the acoustic pressure pulses to
almost zero and assisting in keeping trailing turbulence tighter within the
fuselage centerline... Drag and Lift gains and losses were not anything worth
noting; mostly "shut that noise up"; advantages being greatest using the semi
enclosed fairing option, however both semi enclosed and standard setups nullified
the trailing pressure pulse effects... two thumbs up on this one.

Lunch has now turned into dinner.. there was a brief hiatus in the weather where
the sun came out and a bunch of bananas were lopped from the tree and many hands
cut off; of bananas, not apes...
So just for entertainment and curiosity the fence concept was extended further
to a more aft limit.. that worked favourably; so the concept was developed into
a rib extending to around 1m short of the stern. And that appears to also work
favourably toward keeping air flowing neatly and quietly downstream to the
undercarriage. A secondary affect if shaped with foam and glassed over would be
added rigidity of the belly skin and less tendency for panel drumming.
Peter the fence is just a 3.00mm piece of flat plate running from the lower engine
cowl side face rearward; a block of triangular shaped foam glued to the skin
would also work for a temporary trial... ending it just forward of the fuel
drain vents will function well; the fence height used in tests is 64.0mm.

Have been looking forward to this one...
The outcome was disappointing.. was expecting wind in the cockpit; and thats all
that really happened...
Drag went up 25kg at 100kt for a twin door departation and 17kg for a single door
scenario... on both events the wind came into the cockpit!! It swirled around
and down into the footwells and rear luggage wells, where it swirled around
some more before shooting out straight up at the human head like an upper cut
from both front an rear directions before flying out and over the rear of the
door frame... Anything left loose in the cockpit is getting sucked up and is
going out an opening after slapping the occupants in the head.. for a dual door
situation the swirl remains left and right sided; leaning one's head to the
centre and back may find a pool of calmness... A single door situation is more
exciting; the swirl comes up to the opening on a diagonal from the opposite side
hitting the human closest to the opening in the head from the front and rear
on the way out; anything left loose in the luggage well, shelf, footwell is
going out the opening after slapping the occupant in the face; the occupant can
be human dog or cat... a small dog like chihuahua is probably going out the
opening... a loose ipad; out the opening... and that's about it..
The aircraft is flyable without one or both doors but it won't be very pleasant
at all with 25-30kt winds swirling around like tornado....
Maybe some deflectors will improve a doorless situation...

Interestingly my colombian friend whose door opened in flight reported the
very same thing. His pax grabbed and partially closed the door.
He was worried that the cover would exit the door and wrap round the
tail...In the attempt to catch the cover his passenger let go of the door
handle and away went the door.
They did catch the cover tho.

Thanks for the input William... Its amazing how the computer can mathematically
estimate actuals. Something like a cover could wrap around the head very quickly.
I'm not totally finished on this one yet and want to look at how the complete airframe
responds in the 3 axis environment when a door departs.
All analysis so far are just preliminary static tests to identify generated sound
levels and fluid reaction around the component body.

Some further numbers were run this afternoon after William's comment, focusing
on trailing wash affecting the horizontal stab and items snagging on a control
surface.
Airspeed was increased from 100kt to 150kt with some interesting results... basically,
flying faster reduces the turbulence within the cockpit after a door departs.
The other outcome noticed while slicing through the layers of velocity tracing
was all the turbulent flow exits the cockpit at the top center of each door port;
the sides of the fuselage remain fairly unaffected and away from the wash;
so it would not be too untrue to assume anything such as cloth or lite items
sucked out of the cockpit possess little chance or risk toward hitting or snagging
on the horizontal stab.
So the numbers indicate fly faster to be in a windy bus stop, or fly slower and
sit in a tornado... personally not excited or outwardly wishing anybody find
themselves in the situation to prove the theory correct.

My Arplast PV50 lead screw bearing has gone a bit crunchy so needs replacement.
Im looking for tips and advice please from anyone who has done this before I
start to disassemble. At the same time Im looking to create some spares so if
anyone has the dimensions for the lead screw, bearing and the other parts, or
can help me as to where they sourced them, thet would be much appreciated. Thanks

| Subject: | The Obsidian Files - Departed Canopy |
| From: | "Area-51" <goldsteinindustrial(at)gmail.com> |
This file entry leads on from and related to the Doorly Departed file.
The weather is still crap for everything but ducks, so more numbers have been crunched
as ideas and what ifs spring forth from the ether...
This entry looks at a loss of canopy during flight at 100kt.
With the doors already suppressed the canopy was removed and numbers once again
put through the magic grinder.
What was revealed... the aircraft will still fly without a front canopy or doors...
the turbulent flow within the cockpit is lowered to chest height with the
majority of swirl at across the breadth of the rear of the cabin, leaving the
occupant's heads above within 50kt fast moving free stream air; very exciting
moment requiring good wrap around eyewear... Turbulent air exits the cockpit
along the entire rear breadth of the door port out along the empenage, and along
with air drawn up from the fuselage belly will shield about 50% of the horizontal
stab in very slow moving air; so highly reduced pitch authority would
be a highly probable situational expectation.
With only one door departed the above affects are divided to the side of the departed
door.
That's all for now upon a front canopy departing...

More insight was extracted last night from this study... the above image indicates
how the air enters the cockpit after the door has departed; at the lower rear
frame rail... it then whips around at the centerline toward the front for
the uppercut rearward exit; this creates a vortex in the lower luggage well, and
another in the front footwell to head area.
Several deflectors were tested at 100kt.. upper forward rail visor, side forward
visor, a lower side rail board, and rear lower rail louvre... all additions
performed some affect with the louvre setup providing the best outcome toward
reducing cockpit turbulence to a pleasant level while doorless.

Many thanks for your input. Just FYI I measured the actual ARM last weekend and
it worked out to by 85.5 inches.

Replying to my own post in case it helps someone else.
The bearing is 61800-2Z-SKF and is pretty common so all the usual suspects stock
it. Ill update when I replace mine and post some images.

Mine has no separate reservoir, only the master cylinders for finger brakes mounted
inside the tunnel. See attached pictures.

Hi Paul,
Since you are installing Matco masters, I would put the reservoir on the fi
rewall.
Even the Jamar benefits from the master higher up on the firewall.
Reason: Maintenance.
Matco prefers 5606. It is sticky and stains. Lasts forever but does absor
b water from the air and should be changed out once it begins to discolor.
Dot 5 silicone brake fluid is normally a nice purple or clear but if it st
arts to yellow or turn slightly red, change it. If it is discolored it is
contaminated with water. Dot 5 is nice to use as it doesn't stain if you d
rip some. So I put the reservoir on the firewall as it is easy to get to a
nd inspect on my routine 25 hour inspection/oil change. This requires me t
o plumb more line to the masters. I use the =BC inch OD 1/8 ID vinyl tubin
g for the reservoir line to make that chore easy as there is no pressure on
the line so a simple barb fitting is all that is necessary and it won't le
ak. To clean out the old fluid simply tip and drain the reservoir, then ad
d fresh and pump the fluid down to a bleeder cup/container filled with flui
d until the fluid is clean again. It works fine for me but does require an
assistant. Bleeding from the bottom slave cylinder I can do IAW my articl
e single handedly and it is excellent exercise getting up and down to drain
the reservoir. If working alone, I simply undo the reservoir and let it d
rain into a pan setting on the footwell, but only if I have no need for the
exercise. Plummbing the Matcos does require some head scratching to make
them easy to inspect/service/plumb. Just remember the reservoir should be
the highest point in the brake system to operate properly.
Putting the reservoir in the tunnel is OK but requires the time to get into
the tunnel to check the condition and the level of the fluid. It is a bla
ck hole in there, only openned on the annual normally, and you have to plac
e your reservoir and line where it is easily serviced. This can be done, b
ut it just requires planning. I have my fuel pumps, fuel flow and pressure
senders, parking brake, stall horn, and fuel selector in there, so my hole
is a bit tight on observation space.
I placed my reservoir it where it can be seen (with a flashlight and some h
ead cranking) on the firewall behind and offset from the fuel pressure regu
lator. I should have put it on the oil tank side. Duh...
Best Regards,
Bud Yerly

Whats is the consensus on the best oil.
I have used the Aeroshell sport PLUS 4 oil up to now mainly because I used
AVGAS in Colombia. (Mogas was of doubtful quality.)
I have since heard that lost of people use Mobil Synthetic.
Any thoughts?

>From memory, there may be a discussion about this subject on Recreational Flyer
forum site, or Rotax page on matronics.
The issue with using similar motorcycle grade oils in the 912 is that they do not
have additives for high altitude situations above 4000' i think it was... otherwise
they worked fine; some with less burn-off between oil changes. Aeroshell
also has an additive to flock lead from the oil and transport it to the reservoir.

| Subject: | Oil - Rotax - Synthetic or other |
Getting an oil with enough ZDDP (anti-scuff) is an issue, with this substan
ce being now very diminished in any oil that could be used in an engine wit
h a catalyst (because the Zinc contaminates the catalyst).
Aeroshell SP4 has loads and the new Rotax synthetic oil * is suggestive tha
t it does too (in its comment: Not recommended in automotive applications w
ith catalytic aftertreatment systems).
Sometimes the MSDS will say how much ZDDP is present, other times not. But
if the gearbox screeches momentarily on shutdown, chances are your oil does
n't have enough.

change oil every 25-30 hours anyway as I believe in routine 25 hour inspec

is about $11-15 a quart and MX4T is about $12-15 a quart. Depending on wh

including shipping, and the 4T is about $86 for 6 quarts plus shipping. Ag
ain, depending on where you buy your oil costs change. Since only a few ai
rports across the US carry MOGAS of 91 AKI, I can=99t avoid leaded AV
Gas use. I stick with the SP4. Do I religiously use the TCP fuel additive
? Well, I try to. If cross country and I need oil and the FBO does not st
ock SP4, I use either the Valvoline semi synthetic motorcycle oil or Mobil
MX4T to add if my oil level gets low for some reason.

d Premium 92 Octane R+M/2 is about $4/gallon in Tampa. If I fly 25 hours a
year how much do I save at 5-6 gal/hr with a 25 hour oil change. (Note I r
eally only flew the Europa 10 hours last year.) My gas use would be 137 ga
llons and an oil change is about 3 quarts. Avgas/SP4 at 5.5GPH $962+33 for
oil =$995 but normally with my discount $688+45=$732 and 91AKI Mogas u
se would cost in my area (My FF is 5.8 GPH at 31 inches on Shell Supreme fu
el) $582 + 45= $625 and I must now consider I can=99t get reliable
MOGAS on cross country at the nice airports, however I still have to worry
about bad or old gas that has been setting at the airport and in my airplan
e. For me it is not that much of a difference over a years worth of flying
but, if you only fly local and fly 300 hours a year, you can save quite a
bit. Those folks overseas that can get good super supreme fuel at airfield
s and go 50 hours between oil changes can save enough to pay a month
=99s hangar fee and or a month=99s worth of insurance so it=99s
worth it for those overseas to look for alternatives due to their high fue
l costs and oil availability. For me, in the Tampa Florida area, it just i
sn=99t worth the stagnant fuel issues since I fly so little and SP4 w
orks and is relatively cheap to buy for a specialty oil. As far as auto fu
el goes vs 100LL, my particular 914 likes 100LL. It starts really fast. N
o worries about kickback on start with that fuel, no matter how old it is.
With ethanol laced super MoGas only available here in Tampa, I find that b
y using 100LL fuel, my carbs are always clean and have stayed tuned for 4 y
ears, the floats don=99t sink and my float bowls look like new. Othe
rs in the area are not so lucky that fuel with ethanol gas.

with TCP and SP4 oil and Rotax Filter. The engine was unbelievably clean
on the inside. The oil tank holds the lead in suspension like it is suppos

of carbon from the turbo. There is a new Service Bulletin on the 914 turbo
can which changes the design and adds a filter screen. It may set too clo
se to my duct so I doubt I can change it without lowering the duct. I
=99ll see how much it costs. I like the design but, I probably will be

I would think graphite could change the friction on the clutch mechanism in the
gearbox.
Its a bit of a juggling act!
