To all
On Denis Vories info page http://www.europa-usa.com/enhancements.htm I can read in chapter UNDERCARRIAGE:
The main wheel tire was changed to an inexpensive Mc Creary "Air Hawk" 8.00-6
6ply (ACS# 06-07928) with a 120 MPH load rating of 2050 lbs. The tire looks better
on the Europa, improves ground handling and increases prop clearance by
1 - 2 inches. The brake caliper still had to be ground round at the corners to
provide new pad clearance from rubbing either tire even with the Europa revised
caliper plate installed.
Please, is anybody else installed this tyre? I would like to know before ordering
this tyre by Spruce (76$), if the current existing tyre from Europa can be
replaced by this new one without other changes (on the wheel etc.). I don`t need
to change the tyre for better aircraft looking. I have on my airplane constant
speed Woodcomp propeller with diameter 67 inches and this is more as from
Europa recommended 64 inches. These 1 - 2 inches by the new tyre could partly
help me to eliminate encreased risk of propeller strike.
Thanks very much for answers.

Go with a Mcreary 7.00 x 6 but use the original Europa inner tube due to
the valve fitting
This works really well

Sounds like a good idea to me if you can find a good way of fixing it.
Presumably it's working like the wire mesh on a Davey miner's lamp - by
conducting sufficient heat away to stop a flame getting through the mesh
with sufficient temperatrure to propagate the other side, regardless of
mixture ratio ( which might well be generally high inside the can, but would
locally be lower when the can gulps air to replace the poured fuel) David

As a further reference the type of cans used in the training film
can be seen in the online McMaster Carr catalog on page 1569.
Note that they have a double-mesh flame arrester screen.

Hi Al,
Did you make the drain wire (shield) one of your pins in the disconnect? The
drain needs to be connected so that it runs uninterupted to the stobe when all
is hooked up. Also, you will need to bond the drain wire on the power supply
end to the chasis of the strobe power supply to ground it. If it's not
grounded, it ain't draining and that might be the source of your interference.
You
can crimp a ring terminal on the drain wire at the power supply end and use one
of the power supply mounting screws to land the drain wire. A little
conductive grease under the ring terminal will help also.

John Lawton

If ever proof were needed as to the efficiency of this arrangement for
allowing a volatile fuel/air mixture through, while preventing the
propagation of a flame front, you need look no further than the "flame
traps" fitted in the inlet (intake) manifolds of the Rolls Royce
"Merlin" engine, between the supercharger and the head.
Made from layers of corrugated brass foil about an inch deep, these were
intended to prevent a backfire blowing the supercharger into the next
world. They worked very well, preventing the ignition of a perfect
stoiometric mixture at pressures up to 60" Hg.

Like Tony I used the Mcreary 7.00 x 6 tyre which works well. You will have
to decide for yourself whether you get adequate prop clearance. I am using
64" blades on a Classic monowheel. The recommendation is 62" for Classic and
64" for XS as the engine is mounted 1" higher in the XS. Unladen I get 11"
prop clearance instead of the normal 12". Even with the aircraft laden it
would require a significant nose down pitch for the prop to strike the
ground. Many prop strikes are caused by nosing over during groundloops. In
this situation it is unlikely that a prop strike could be averted as the
aircraft tends to continue pitching until the prop strikes whatever the
original clearance. It might make a difference if the tail is lifted by a
gust of wind or excessive brake is used. In both these cases quick control
responses might save the prop from ground contact.

I use the MATCO parking brake. It works very well. It is important thet it
is placed in a position where it cannot be inadvertantly selected. As it is
a hydraulic valve it will prevent brake application if it is selected with
the brake off. If it was knocked on in flight no braking would be available
on landing. Whilst the mechanical cam parking brakes are cheaper they are a
little more awkward to use and take more time to make and set up initially.
They are usually designed with teeth so the exact setting will be defined by
steps. Unless these steps are kept small the exact amount of brake pressure
with the parking brake set will change as the pads wear. The hydraulic brake
by contrast will hold whatever pressure is applied by the brake lever.

By definition, static electricity results from the contact of two dissimilar
NON-CONDUCTIVE materials, otherwise known as insulators. Rubbing, or other
relative motion, merely increases the effective contact area.

Fuel is nonconductive, so I can't see what it has to do with static.

I have installed the Matco valve in my not-yet-flying Tri-Gear (and also
added a set of foot brakes to the right side), and have located the valve
within the tunnel, just to the right of the 914's throttle quadrant.
Although I have seen Dennis' monowheel Europa a few times I don't recall
where he put the valve, but from his description it sounds like it is about
where I located it. Having a big empty space in my tunnel I can't comment
on whether the valve will interfere with the monowheel's operation but the
valve is certainly small enough to fit somewhere in the cockpit. I can
provide a drawing of the bracket I fabricated to mount the valve and details
of the extension shaft to put the operating lever above the tunnel - contact
me off list if you want more details.

In the location where we mounted the Matco valve in our monowheel XS, there
was not quite enough clearance to the tire. To increase the clearance, we
cut through the top of the tunnel on three sides of the valve, leaving a
flap of material attached along the front edge. Bending the flap upward and
glassing it in place made a very satisfactory installation. For a picture
(and a bit more explanation), see the description of various modifications
made to N135TD on Bob Jacobsen's web site:
http://www.europa-usa.com/n135TD.htm. We strongly recommend this parking
brake valve.

For my mono I have found a simple wedge of alloy, (the same thickness as the
brake lever slot) to work very well and it probably beats everything for
lightness and simplicity. You just drop it down in front of the lever when
you park, so as to take up all the space when the required braking force is
applied. It has a loop of cord through its thick end which stops it being
able to fall thru the slot, and hangs it over the handle when not in use.

Our Matco valve is not an on/off valve, but rather a check valve. When it
is on, brake pressure can be increased at any time, by pulling on the brake
lever, and the valve will prevent the pressure from falling, when the brake
lever is released. The usual operating sequence is to flip on the parking
brake, and then pull on the brake handle. Nevertheless, it would not be
much fun to have the parking brake engaged during landing. "Brake off" is
an essential part of our pre-landing check list.

--> Europa-List message posted by: Terry Seaver <terrys@cisco.com>
Hi Jim,
We ended up with a slight opening/gap on the port side when the rudder is centered.
With our mono-wheel installation, we found the ground handling VERY challenging
with the 2:1 ratio to the tail wheel. After a ground loop fairly early in flight
testing, we modified the bell crank at the rear bulkhead for a 1:1 ratio.
Our tail wheel travel went from nearly +- 90 deg to +- 45 deg of travel. Ground
handling became much more manageable after the
change. In my experience with various tail wheel aircraft, the tail wheel travel
is more typically +- 30 degrees, so our travel is still pretty aggressive.

Nigel,
Are you sure that you haven't got your valve arse about face? If you are
talking about the "MATCO PV-1" then this is the same valve that is supplied
with the factory finger brake kit for the Trigear.
A quote from the factory installation instructions:-
"The parking brake valve provides a means of retaining hydraulic pressure in
the lines between each wheel brake calliper and the valve. When the park
brake is set to "on" a check valve allows further pressure to be applied by
pulling on the brake levers."
The factory kit has the valve orientated with the flow from the finger brake
cylinders to the larger flat face of the valve and then out to the wheels
via the two ports on the smaller face.
I interpret the factory instructions as describing this as a one way valve
that is selectable in or out (of the system) rather than a on/off system.
If you have the valve connected the factories way round then you can select
the valve to park first, then apply wheel pressure which the valve will
hold. I suspect that you are having to apply wheel pressure first, and then
select the valve. Selecting the valve first (if it is installed backwards)
would stop pressure getting from the brake levers to the wheels.
Apologies if I'm talking b#ll##ks
Regards
Simon Smith

I use the MATCO parking brake. It works very well. It is important thet it
is placed in a position where it cannot be inadvertantly selected. As it is
a hydraulic valve it will prevent brake application if it is selected with
the brake off. If it was knocked on in flight no braking would be available
on landing. Whilst the mechanical cam parking brakes are cheaper they are a
little more awkward to use and take more time to make and set up initially.
They are usually designed with teeth so the exact setting will be defined by
steps. Unless these steps are kept small the exact amount of brake pressure
with the parking brake set will change as the pads wear. The hydraulic brake
by contrast will hold whatever pressure is applied by the brake lever.

I have to endorse David Joyces "wedge of alloy" as a simple, cheap and
effective parking brake.
Ours is made of tufnol but the material is irrelavent. It is possible to
apply as much or as little pressure on the brake lever as required
regardless of play or wear in the rest of the system and the cord stops you
loosing it.
We have used ours for a year now and cant imagine why you would need
anything more complex.

Thanks to all who responded. My plane is still in the open wing stage and I was
a little concerned about RF since I placed a connector in the wing at the inspection
panel. I thought I might have too much unshielded wire in the wing but
have come to the conclusion that that is probably not a major problem as long
as I install the drain wire (which I had planned to do anyway). I just didn't
want to close the wings and have to go back in because of RF problems.

We simply installed the wheels, as received. If you come up with some kind

Dave,
Thanks for the update...
Soaring is OK isn't it ;)
We are still plugging away at our MG. The top was glued on Saturday and the
landing gear functions as it should. It's so cool, it looks like a plane!
