Bud - I'm intrigued to know that vernier throttles can be fitted to the Europa.
I am a fan of vernier throttles ever since flying with one in a hired Bonanza
years ago, but I don't think I've ever seen one fitted to a Europa. Can you advise
how this is achieved?
I have seen push-pull throttle knobs with dual cables, but never one with vernier
adjustment _and_ dual cables. Obviously one could make some sort of intermediate
bellcrank arrangement under the cowl to operate 2 carbs from one cable,
but I suspect that would be a lot of work to get approved here in UK. I'd hope
that _if_ a dual-cable vernier knob was available, that could be installed without
so much approval hassle.
(Yes, I know that instructors don't like vernier throttles as a student's hand
can obstruct the lock, preventing the instructor from opening the throttle in
an emergency. Yes, I know that military folk prefer lever throttles to push-pull.
But I know what _I_ like!)

I put a single vernier throttle on A143, it was very straight forward as the attached
photos show.

Thanks to all for input
this wiring/instrument thing is pesky

I did the same as Frans, used brass bolts through the firewall as the main
star points, I fed 5 wires with ring ends through a hole from the instrument
panel and connected on the bolts so I can easily remove the instrument
panel. I had noisy and quiet power and return and alternator output. Really
you want the battery to be the bus (but then my battery is in the FWFD). In
the instrument panel again I wired to brass bolts on the ledge 2" from the
bottom for ground star connections to low power instruments etc.

| Subject: | Should top wing skin be simulated when bonding on wing-profile |
jig
Hi Bud,
Yep, my plan is to use one popsicle stick plus a layer of tape as a wing
skin simulate before finalizing the flap hinge positions.
Thanks, I will use these techniques when setting the wing incidence (not
too far away from it, now). They will be quite useful.
thankyou,
Greg

Greg,
I find that measuring the wing skin thickness and using spacers to be the
idea way to set the wing incidence when using the incidence board. You will
notice that the wing skin has about a 1/4 inch of foam but that foam ends
before the root rib. The skin is about 6 layers thick at the root or about
a popsicle stick. The big thing is to get both wings the same. Get anal
about it and use a good digital level, the same incidence board, a spacer
set about 2 inches in front of where the rear pin goes, and I even hold the
level with the digital screen facing the same way at the same exact position
on the incidence board. Then, before I glue it final, I step back and
check by eye, the lower skin of each wing of the aircraft from behind to
verify that the bottom of the wings both are at the same angle. See my
website for trimming the Europa.

<gregoryf.flyboy@comcast.net>
To Any/All builders,
Before bonding the wing profile jig on the upper part of the wing (when
installing flaps on the wings), is it assumed that the upper wing skin
thickness should simulated with a suitable spacer such as popsicle sticks or
such? The jig, when placed on the wing root, lines up with the indentation
where the top wing skin would be, at the rear of the wing. I placed lately
taped-in sticks at the rear of the wing, where the jig will be set, to
simulate the top skin, in anticipation. The difference between both ways is
only in the 1-2 mm area, but anyhoo.. Including spacers looks like it would
-slightly- increase the reflex of the flap. Just trying to get a feel for
what others have done, or interpreted this move. A short search on matronics
did not eek out any results.

Rowland,
Verniers are great for throttles for aircraft which need a very fine
adjustment like on the Beechcraft you flew. (I personally am a fan of
the Debonair, loved it and the vernier prop control was really necessary
due to its linkage.) However, by a chore I mean that you must come up
with some sort of single to dual cable arrangement that is full proof
and easily adjusted. The support of the cables, the vernier end and the
fittings will run you well over $100. The vernier screw has a lot of
leverage so it can easily pull hard enough to bend the idle throttle
stop on the Bing style carb, so some sort of stop has to be included in
the mechanism to prevent bending the stop from inside the cockpit when
screwing out the throttle in the pattern. The ergonomics of the Europa
interior make a vernier motion and attachment and plumbing in the panel
a bit difficult without some time consuming cutting and fitting. Some
of the nicest were in tunnels that were cut down to allow a flat area to
rig the mechanism. I've even seen one through the panel, which makes
panel removal more of a pain. I prefer to pull the panel quickly to get
behind the panel work done by easily removing the whole box, so I have
never done such an installation.
I have found that a lever is just dumb simple and the max and idle stops
are a breeze to fabricate in minutes. I have spent hours making a lever
to easily adjust my throttle friction to lock my throttle from creep,
yet be easy to move in formation flying, and frankly it was a waste of
time, but a fun exercise. Whereas the vernier has a lock built in.
(Yes, I nearly cracked up a Zenith 701 during a STOL power off 35 knot
min roll landing test, when on final, Roger, the Zenith factory pilot,
locked the throttle on the pilot side while I was flying, which also
locked my instructor side throttle. Luckily I swapped ends at the last
second and prevented a bone crushing landing. Needless to say we
discussed it over a beer.)
The Rotax / Bing carb does not require a very fine adjustment so I see
no need for the extra time and effort on the installation, but by all
means if you are interested in a one of a kind, personally customized
aircraft, that is the beauty of the kit aircraft. If you want it, go
for it. It is your time and patience.
Regards,
Bud
