That info is in the excellent booklet(s) by Don Dykin, which I could
possibly be persuaded to send you a copy of. Where are you? David Joyce,

Cut a hole in the baggage bay support to allow access to the bolt. It's onl
y plywood supported by fibreglass so a couple of small holes wouldn't be a
problem.

et.com>
Hi,
l I need to replace my electric flap actuator, ie both motor and lead screw
assembly. However, the mounting bracket FL26 is bonded and bolted to the f
uselage floor (Build manual 28T). Removal of the AN4-23 bolt is not possibl
e owing to location of the baggage bay supporting structure. Please advise
how to remove the existing actuator.

Oshkosh is on schedule, July 26 - August 1. The arrival Notam has been published
and EAA is selling wristbands on line. I have requested a forum for Europa
enthusiasts and will post the date, time and location as soon as I receive it.
We're looking forward to seeing everyone. Sorry Tim & Kingsley can't make
it this year.

| Subject: | Flap limiting speed 83 kts exceeded |
One of our group members got distracted during climb out after take off, while
the flaps remained extended to 18 degrees. Shortly his speed reached or slightly
surpassed 100 knots, so the exceedance was about 20 knots before he quickly
stowed the flaps.
After carefully examining all the flap hinge plates, the fibre-glass surrounding
where they are embedded, hinges inside the fuselage and surrounding structure,
flap root pins and the flap root structure generally, flap push-pull rod and
lever, no evidence of damage could be found. Subsequent flight confirmed that
the flaps seem to be in perfect working order. It also seems that the whole
construction is commendably robust.
So my questions are "How is the flap limiting speed determined by the designer
and what if any factor is allowed in calculations for possible overloads?"

Read both of the Dykin writings. They are very informative, however neither provide
the information being sought... Specifically searching for actual airfoil
profiles employed on the Europa; profile plotting data in excel spread sheet,
CSV coordinates, or title tag of airfoil.

No doubt you've read the PilotFriend flight test report http://www.pilotfriend.com/flight_reports/reports/18e.htm. At the end under Europa History is stated " Don Dykins designed the Europas wing. Don, as former chief aerodynamicist at British Aerospace, had directed the development of the advanced technology wing of the Airbus."
While building my Europa Classic between 1994 and 1997, I recall seeing it written
somewhere that the Don Dykins wing profile became known simply as the "Europa
profile" and I'll try rummaging through my large pile of Europa info to see
if I can find the reference you seek.
I'm fairly confident that it was never accorded a formal unique reference listing
in any airfoil database.

| Subject: | Re: Europa Monowheel - Cross Country Flying Machine |
Thanks for the reply Erich, interesting story and good advice. Certainly makes
me feel more confident and I have to say that I have been practicing and my landings
are becoming more controlled with a very small percentage of them with
a small bounce. This weekend I did a nice two hour cross country and enjoyed it
greatly.
Although I am sure that your landing story still applies to my airplane, am I correct
in assuming you used your split gear/landing feature to land with less
flaps during that extreme wind condition?
Best,
Chris

Cool Erich, I see it. However, not very eager to mess with my instrument module
now. Too lazy :)
I think I am going to try just a couple of NACA on the sides. I measured where
to put them to keep them out of the way. I will copy the ones in my LongEZ which
work well although those are located on a place where the angle favors them
greatly (compared to what it will be in the Europa)

I believe that the stall warner mod has a profile of the forward most 6 of the
wing profileFred
