Greg,
You may mix to different mods - the bubble windows (to give more head
clearance for tall pilots, and which I believe must be implemented when
ordering the kit - cannot be retrofitted?) and the door width mod (to give
more internal lateral space.
This latter mod affects only the interior of the aircraft, it does not
change anything on the outside (as the bubble windows do). The interior mod
does not affect the windows, it is only the lower part of the door that is
made thinner and the lower door sill is made more narrow.

Ken,
Of course this may be the first thing you checked, but an incorrect
rigging of the throttles may lead to boost irregularities when in the
100/115 % throttle opening range.
What you are describing reminds me of what COULD happen if the throttles
are not in the full 115% position, and are stuck somewhere between about
108 and 115%.
Do you have the required 100% gate on the throttle lever ?
Best regards,
Gilles

In my previous posting on this subject today, I wrote that the bubble
windows could not be retrofitted. Now, this was my mix-up of bubble windows
and the "high-top" version, where the whole upper fuselage half is "lifted
at the front and hinged in the rear".

| Subject: | Thank you, John Lawton. |
Last year, I had the pleasure of flying into John's airstrip, in
Tennessee and visiting with him and his near finished bird, for a
while. In our conversation, John mentioned how sealing up the aircraft
would clean up the lines, resulting in better speeds. As John said, the
glider guys do it and it works. Well, while I had Baby Blue
disassembled and was cleaning her up for Sun-N-Fun (which she did not
make, as she was still ailing from the weak carb spring incident) I
decided to add some gap seals to the wing, to seal the flaps, upon
retraction. What I used was a 2.25" wide piece of .020" styrene, a
product that I use, almost daily in my sign/graphics business. I
attached it to the wing using 1" hem tape (a very strong, two sided
tape, used to hem banners). Once the engine was restored to normal
operating condition, the results were immediate and astounding. I
haven't done a complete test, yet, but the results seems to have yielded
about 4-5 kph at cruise. It has also resulted in more float, during
landing, which I attribute to reduced stall speeds. I say reduced stall
speeds, because, by reducing my final approach from 65 kph to 60 kph,
across the numbers, Baby Blue lands like she used to. I'll be doing
more extensive tests, as the weather settles. However, I am extremely
pleased with the initial results of the simple and inexpensive mod.
Thanks again, John for your suggestion...

The fuel pressure was constant around 24 with both pumps on. The hoses look attached

Ken, this may not apply to you but I have a Whirlwind constant speed
prop with a Jihostra hydraulic prop governor. If my engine oil is not
fully warmed up, the prop governor will not hold a constant pitch.
Rather, it will change pitch back and forth causing an RPM surge up and
down. If the oil is at normal operating temperatures, no problem. It's
a long shot, but this may apply to you. Good luck sorting this out.

Hi all.
For what its worth I always travel with my jacking block. I have had one
incident where my tube blew out on landing at an airport away from my home
base. It would have been very difficult to deal with the situation had I not
had a jacking block with me.
To give you an idea I had 5 hefty guys to help be move my aircraft and it
was a major effort to move it the 3 ~ 4 meters required to clear the
airstrip.

It has an amazing combination of virtues - I was getting quite
interested in a Sportcruiser until I saw that it can only manage 105
kts at 5500 rpm from a 912 ULS. That makes the Europa a rocket ship
by comparison.

| Subject: | surging engine on take-off |
Ken,
I would double check the prop governor. Especially since you stated the
problem did not occur during the static run up. Not knowing what prop
you have, is it possible to set the pitch manually (not rpm)? If the pr
op is an electric controlled unit, while the engine is off adjust/set th
e pitch to approximately 22 deg and then pull the circuit breaker. Now
you have a fix pitch prop, effectively isolating the governor. Perform
a static ground run up and verify engine performance. With the prop iso
lated any surging noticed during the take-off roll can then be attribute
d to the engine.
If problem still persists, check throttle potentiometer for correct resi
stances. As you are aware the turbo will surge between 108-110% throttl
e position.
Also, you can always isolate the turbo. This is a little more difficult
since the default position of the waste gate is fully closed. In order
to bypass the turbo the waste gate must be manually set full open. Thi
s can be done one of two ways. The first and simplest, is to cycle the
TCU, and when the waste gate is fully open, electrically isolate the ser
vo motor (two pole switch installed per Rotax manual). This is a two pe
rson activity, as one will need to watch the waste gate cycle and call o
ut the moment it is fully open so that the person in the cockpit can iso
late the servo motor. The second method would require you to disconnect
the servo cable at the servo motor, fully opening the waste gate. Of c
ourse you will still need to electrically isolate the servo motor. Nex
t perform a ground run up and verify you do not exceed max RPM at full t
hrottle. If problem persists during take-off run abort take-off.
Other checks of the turbo system, ie pressure sensors, 3-way solenoid va
lve, etc. can also be made with relative ease.
Finally, you mentioned a drop in RPM from 5700 to 4800, do you recall wh
at the manifold pressure was at the time?
Good luck.

I am with Karl in tire changing technique.
I have a nicely primed and painted 1" steel bar about 18" long to slide
inside the axle. Several steps but not hard. An actual trigear jack point
would have been a nice design feature.
Its time, after about 70 flight hours to replace my main tires again.
I've been using new Goodyear Flight Special II tires and these prime
tires last fewer than 400 landings on concrete, both sides losing outboard tread
at a prodigious rate.
I wish there were a practical fix to this design "feature" as it is a bit pricey.

I have a support which goes underneath the tank area. It
has two scissor jacks, with their screws connected
together with a wooden board across the top onto which I
also place a spongey mat.
With this I can jack up the whole of the rear of the
aircraft (with the weight on the nose-wheel and the jacks)
until both main wheels are off the ground. Then dealing
with the wheel and tyres is easy !
I could include a picture - I would need to take it and
the fuselage is not available at the moment :-(
I had a similar "outside edge" wear problem. I have been
told it is because the gear legs were not installed
correctly ! I changed the tyres at 175 hours, but all I
actually did was change them on their rims, so that the
worn part is now on the inside edge. I reckon on that
basis the tyres will last for 350 hours !
Please note that changing left to right without changing
on the rims will leave the worn part still on the outside !!
The tyres are the standard ones.

Hey Jeff...
I've also had email exchanges w/ John Lawton and have perused a site he
recommended for info on gap seals...all very interesting. Could you go
into a little more detail on the nature of your installation? Exactly
where and in what plane have you attached this styrene? Does it create
a pressure seal?. In what way does it alter the airflow?

The bubble windows are a straight replacement for the original windows

right in that the three available size-increasing mods (door sills,
bubble canopies, and raised top) are all independent and can be
compined in any combination.

Ken,

So the throttle cables are ruled out.
Nevertheless, the absence of the required 100% gate reminds me of what I
have seen happen on a few occasions : when advancing the throttle at
takeoff, the pilot fails to push it all the way, at leaves it in the
100-115 % sector where Rotax advises that turbo operation is instable.
And indeed, the result was "attention getting" power surges ;-)
Could this have happened ?
> but have a manifold guage which I did not look at.
Too bad, as the reading could have helped discriminate between
governor/prop and engine trouble.
It is good practice to monitor the two gauges during the takeoff run : I
always make sure the RPM are 5800, and manifold pressure 39.9 in Hg.
Some pilots reported a stuck waste gate, or a runaway prop governor.
All the best with your investigations,
Best regards,
Gilles

Graham,
Yes, I'm sure it is styrene. I buy it in 4 x 8 sheets at .020"
thickness for under $7. a sheet. In the sign industry, we use it for
commercial displays. Cut to size, add your graphics and a few strips of
velcro on the back. It's not the same as the stuff used by the glider
guys, but is apparently just as effective, for a much lower price...

Fred,
I took some pics, but haven't had a chance to post them. The process is
dead simple, though. I cut two pieces of styrene, 2.25" wide, the
length of the flaps (about 63"), then added the hem tape to one edge.
The tape is 1" wide, so I marked back 1" onto the wing and drew a line
with a grease pen, parallel to the underside of the wing edge. I then
notched the styrene, where it had to clear the flap hinges, removed the
backing tape from the hem tape and applied the strip to the wing. The
width was such that it covered the gap, spilling over onto the flaps.
It is not truly a pressure seal, but is sufficient to direct the air
under the flap and not up, into the closeout. My guess is that it also
deflects the air, under the flaps, even with the flaps deployed, as
there is a definite lack of drag. If you do this mod, be prepared to
re-learn your approaches and it wouldn't hurt to have a good bit of
runway on the first few attempts...

The jacking block is a great idea but if you are without one there is
another easy solution.
Most jacks kits (aka Halfords) and calso ars come with foldable metal
wheel chocks.
Open out the chock as you would with a car and hold the face of the
chock (which would normally face the wheel) against the underside of the
swinging arm such that the top edge of the chock sits against the two
boltheads which protrude from the underside of the arm. They are only
about 3mm in depth but it is sufficient to support the weight of the
aircraft.
The jack is then placed underneath the chock and as long as pressure is
applied it will hold the chock in place and enable the wheel to be
jacked off the deck and removed for repair.
Because the chock is made of thin guage mild steel it will seat itself
against the bolt heads and there is little chance of being displaced.
None the less it would be sensible to support the swinging arm with a
block of wood while the wheel is away being fixed.
Its not as good as the proper block (discussed in this forum) but as I
said it is a readily available solution which will get you out of a fix.
I have used it a couple of times as I have had problems with the
hydraulic brake cylinder siezing and locking up the brake.

The flaps on the Europa are Slotted Flaps. They are designed to let the air
go thru the slot from the bottom to the top of the flap. The next step up is
the Fowler Flap design.

Jeff...Thanks for your very clear explanation of your installation.
There are no doubt folks on this list w/ more knowledge of aerodynamics
than I, but I believe that the Europa flap design is such that when
deployed, some portion of the increased lift is the result of air
flowing over the top of the flap as the flap drops and moves to the
rear when deployed.
Of course even when the flap is retracted, some air will find its way
up thru the gap between the leading edge of the flap and the vertical
face of the wing closeout, and it is this airflow which one wants to
eliminate in order to enhance cruise efficiency.
If this is so, it would seem that another way to get this increase in
cruise efficiency might be to install a compressible strip which would
close the gap when flaps are retracted but allow airflow over the flaps
when they are deployed, thus maintaining the short field
characteristics of the aircraft which, if I understand you correctly,
have been changed.
Keep us posted on your testing,
Fred

Adding compressible strips in the flap closeout was suggested to me some
time ago by a person with many years of aeronautical design experience.
The key is to close the airflow from lower to upper surface during
cruise but to ensure that the lower to upper airflow over the flap
remains per the design spec when the flaps are down.
This is quite easy to achieve by adding some light doorstop strip into
the flap closeout and, in many cases, will have already been achieved on
the port side if the pitot/static lines were run in the flap closout as
part of a retrofit.

| Subject: | surging engine on take-off |
Ken,
This sounds a lot like the problem I had coming back from Oshkosh last year.
My problem was surging while in the air and the engine seemed to always work
on the ground. My problem was a plugged static pressure sender going to the
TCU control circuit. Problems like this can be caused by the airbox or
static pressure sensors or a leak in anyone of those little black hoses. I
pulled each off house during troubleshooting my problem and used a small
syringe to pressure them up in some soapy water to look for pin hole leaks.
My problem ended when I pulled the static pressure sensor and found the end
block with a rubber cap the painter had put on to keep out the dist and
overspray.
Just a thought for other places to look for your problem.

Subject: Europa-List: surging engine on take-off
Yesterday taking off, the engine surged as the turbo kicked in it went up to
5700 RPM then dropped back into the 4800 range. I tried several runs but
aborted the take-off as it continues to surge. Checked the prop governor
and it checked out as functioning correctly.; Took the cowl off and the
turbo arm seems to cycle correctly when the master turned on and the
throttle cycled. Tied the plane down and ran it up to 5700 rpm. It did not
surge at all.
Any idea? I have not tried to fly it again yet.

I thought about it, but believe that the aileron is sufficiently
recessed to negate the need. My opinion, of course. I also considered
the compressible seal, but did not have any around the shop. Might
still try it out, as replacing the styrene would be easy and cheap,
should I decide to return to that...

Hi! Welcome back ....but which build I thought you'd completed one at
least?

Subject: Europa-List: I'ze back!
After a six month battle to resolve a major stuff up by a US based
internet service provider - which resulted in many US locations being
unable to send mail to us because they'd redirected the routes for a
large chunk of NZ internet addresses via Japan, I am now back on the
group email list.
Now all I have to do is finish the build!

| Subject: | Europa Widen Shoulder width door mod. |
Ok, so I will make a guess at this (a few pros and cons, based on the
responses so far)...
The bubble windows are for tall pilots, and are very easy to install, but
may have a negative affect on the airspeed, due to the way it pokes outside
the circumference of the aircraft. It would be a good choice for someone,
where speed is not of the essence, and limited time spent on the mod is.
The door sill mod increases the shoulder space of the Europa (by 1.2"),
requires a bunch of work, but does not affect the cruise speed of the craft.
The raised top method increases the height of the fuselage top, again for
tall pilots. It needs to be implemented during the build of the craft, and
will raise the forward upper part of the fuselage, and not the very rear of
the upper fuselage. It requires a bunch of work, and I must believe that
because of the increase of the frontal forward surface area of the craft
(that the air stream will see), that it will affect the cruise speed by some
extent. Probably to a much smaller extent than the bubble windows, due to a
retaining of the original sleek upper fuselage contour of the Europa.
Possibly the effect might be negligible.
Anyone see something I am grossly missing?
More importantly, are there any real world results that confirm any of this
speculation?
It would be nice to have a more complete grasp of the advantages and
disadvantages for the above modifications.
