| Subject: | Undercarriage & Flap Lever on the XS Mono Wheel |
My thoughts on this: Any extra long lever would need to be dog legged as the
top of the existing lever fits into the recess in the panel. Also the force
needed is very depended on getting the bungee tension correct. If this is
high enough then the force needed to retract or engage the undercarriage
will be minimal.

Subject: Europa-List: Undercarriage & Flap Lever on the XS Mono Wheel
Has anyone ever created an extra long lever or an additional attachment to
make the Undercarriage Lever easier to operate?
I have arthritis in the knuckle joints of the first 2 fingers of my right
hand and found it quite difficult to push the lever forward to put down the
Mono Wheel & Flaps.
I was thinking of a longer lever which would give more leverage?
Thanks in advance for any suggestions/advice.

James,
Ted Gladstone and Justin Kennedy have done several mods to their
Monowheel
Z-TED, including the following reported on the Matronics list as
follows:

Subject: tric Flaps on Monowheel
>Shaun Simpkins wrote:-

>Has anyone out there tried decoupling the flaps and gear on a
monowheel<
We are the Edinburgh group who have fitted an electric screwjack
actuator to
operate the flaps on our monowheel Europa. Rowland is correct in that
the
actuator was originally designed to operate the elevation mechanism on a
lounge chair or bed for the elderly. It weighs about the same as the
long
cranked linking tube and its associated couplings. We also developed a
manual emergency method lowering the flaps, should the electric motor
fail,
but Francis Donaldson (PFA Chief Engineer) did no share our enthusiasm
for
it and we locked out this device. Along with many other mods we have
also
changed the lever that operates the undercarriage such that it rotates
from
a horizontal position on the tunnel through 180 deg to end up again in
the
horizontal position on the tunnel. It allows us to fill up the cavity
in
the instrument panel and it can now be operated with a single finger!
The electric flap motor also operates the outriggers in the normal
manner
(for the time being) but we have the intention to also operate the
outriggers with small electric screw jack actuators. When this is done
we will be able to operate the flaps to any angle but, with the existing
setup, we can go down to 30 deg and op to 23 deg without unlatching the
outriggers. At the moment we have decided to abandon any further mods
and concentrate on getting it flying ( it's kit No 15!!!). When its
flying we can amuse ourselves with our further mods and go faster
fairings.

G-ZTED
While this may be too radical a solution for you, the principle involved
in
making the undercarriage lever rotate through 180=B0 has clearly
resulted in a
very light operating force. I have always found Ted and Justin very
willing
to share their Europa experiences and am sure they would be happy to
discuss
ideas on the subject.
Best regards,
Mike

Thanks,
Am I correct in assuming that the aforementioned metal rod (would a
sturdy tube do?) goes in where the attachment for the wheel pants goes
in? Or does that one somehow fit into something else that is mounted
within the wheel axis? (please see attached photo)
Any other options BTW? What if you needed to work on the landing gear
strut for an example, and didn't want the fuselage to be standing on it?
I saw that suggestion about suspending the fuselage from the engine
mounts and the tail. My local mechanic who's helping me with all this
wasn't very fond at all of that idea.

To raise the nose wheel I use at least two 30 liter cans of fuel/water to we
igh down the tail with a padded strop over the fuselage in front of the fin.
To service main wheels I use the method described using a piece of steel tub
e pushed in to the axle, a jack and a piece of 1 inch ply to support the leg
.
