Subject: | Re: Jamar vs matco |
While I do not have a Europa (I have a DynAero MCR-4S - don't shoot me) I belong
to this list because of its Rotax 914 experience.
I however do have finger brakes and chose them against foot brakes because of weight
considerations and simplicity. If it is of interest and help I am happy
to provide photographs of my installation which may be of assistance. The DynAero
finger brakes are lighter than the Matco ones picture already published
and have a locking mechanism which holds them on for parking and run-ups tests.
I am happy with my choice.
Let me know - happy to help
Cheers Peter

Hi Malcolm,
I am in Brisbane, Australia and have had previous correspondence with Ian Rickard
and cc'd yourself.
Ian does have a CAD drawing of my proposed engine mount which I have yet to carry
out an FEA analysis on. The date of fitting my engine could still be at least
a year away.
Let me know if you want to find out any more details. I would be very interested
to see how your conversion works out. Ian did send an early photo of your 260i
mount adapter for the Europa.
Regards
Martin Benson

Subject: | "Flight into known icing conditions prohibited" |
- is one of the placards on my panel, next to "VFR operations
only". We all have heard about the danger of icing, and we understand why
it can be fatal.
Today I ran the engine on idle for 3-4 minutes on the ground (prior to
squirting engine conservation oil into the carbs until stopping, for winter
storage). It was a foggy day, air temperature just around freezing. A
soft, very thin layer of frost formed on the wings and fuselage when pulling
the aircraft out of hangar. I had not, however, expected to see the rapid
build-up of ice on the propeller during this very short run - see the
attached two photos. There was no ice on the front face of the blades, but
on the sharp leading edge there was a 4 mm buildup of clear, very hard and
difficult to remove ice (gradually diminishing towards the blade root).
This is seen as a white stripe along the leading edge on the photos. Ice
had also begun to build up on the blade back face and on the tip edge.
One can only imagine the loss of propeller efficiency and risk of vibration
if flying through clouds or fog around/below the freezing point. I did not
need this demonstration to heed the placard's warning, but it does bring the
message home.
Fly safely!
Regards,
Svein

All the recent postings about appropriate fluids for the tri-gear finger-brakes
has prompted me to think about what is OK for the monowheel brake system. I'm
using the standard Europa parts. My journal shows that, when fitting it, I cleaned
up & lubricated my master cylinder with Castrol Girling Universal SAE J1703
(which appears to be DOT3), and later I bought a can of DOT5.1 with which
to fill the system (when I get that far).
I note Neville's enthusiasm for the red aircraft grade brake fluid (what's the
proper name for that? Can I get it from LAS, for instance?) but also that Europa-supplied
seals may be an unknown quantity with respect to what fluid they like.
Is there any way (other than soaking them in a sample of fluid) to determine what
seals I've got in my master cylinder and in my brake calipers?
If the seals held in stock by Europa are not identifiable, where else could one
get seals properly identified as to type of fluid for (a) the monowheel master
cylinder and (b) the monowheel calipers?
in friendship

Hi I don't know what seal are fitted in your brake system so to be safe
you must use DOT5 fluid no other.
To help with bleeding the system first apply the brake on the wheel you
are not attempting to bleed and tie the brake finger leaver in the on
position. Now bleed the other brake circuit from the wheel cylinder by
using one of the std pressure bleeding kit's [Airworld 300981 worked for
me] that way you will drive the air up and out of the system at the
header tank. Once you are clear of air on the first circuit lock the
bleed nipple shut and repeat the same procedure on the other circuit.
Good luck Richard

Thanks for the advice, I've just come from the airfield having done a
bit more investigation.
Attached is a picture of my master cylinder, apparently it's a "New
Jamar finger brake controller all filled with DOT5.1 fluid filled from
the wheels as per the build book"
Apparently I have "Matco 5 inch discs on the wheels with new seals
fitted."
I just popped the cover off the levers to look at the master cylinders
and there are A LOT of very large bubbles in the left hand tube leading
out of the master cylinder.
I have just bought a bleeding kit and some 5.1 and will try to sort it
out tomorrow, I'm just worried there is a leak or something - as it was
fine last week but absolutely terrible now..
Do you think a simple bleed from the LH calliper will do the job?
Regards,
-Carl.

Describe the type of master cylinder you have as well as the type
wheel cylinders. There have been a few master cylinders of inferior
quality experienced by several builders.

Subject: Europa-List: Europa Finger Brakes
Can I just get a bit of advice from anyone with finger brakes fitted?
Mine seem to be a bit odd. Firstly, if i just pull a single one of
them it will hit the stop, whereas if i pull them both they have more
feel and don't hit the stop quite so much, however they seem to respond
better with a bit of pumping first.
Essentially I'm saying that they appear to be substandard, need
pumping to work properly, and even then pulling just one doesn't seem to
work well.
Any thoughts on what could be wrong? An engineer investigated it but
couldn't find anything wrong - he checked they were bled and suchlike,
he then reported it was caused by the fact the master cylinders were not
big enough for the callipers so they need pumping.

Rowland,
The original name for the red stuff was DTD585. I think the latest stuff
has an H on the end. LAS do stock it.
When I had a Mono setup I used exactly what the manual said to use (dot 3 or
4)and had no problems.
Regards
Brian

Subject: | Re: "Flight into known icing conditions prohibited" |
A number years ago I was flying along the Alaska coast on a job in a Hughes 500.
The fog keep getting lower and I had to fly lower to the ground. Then the
whole helicopter started to vibrate through the controls to the point I had to
make a landing quickly. Once on the ground I shut the engine off and there was
about 1/4 -3/8 of inch of ice along the leading edge and under it.
