I did similar to this, servo in the spar tunnel horse shoe spring hooks
up
to the control arm next to the aileron link rods

I elected to go with a homemade single composite horseshoe spring on the
end
of a mac servo (jack-screw model) - very easy to adjust the spring rate
to
one's liking..... just add/remove plies accordingly, and less chance of
breakage fowling the controls imho :-) ..... & nope not on my Europa
:-(

About easy trims.
If it can go wrong, it will, and the more complex and wonderful, the
more
chance for extensive troubleshooting problems.
I prefer a built in aileron tab into the aileron with the servo attached
and
aileron balanced. Looks and operates well. a 10x1.5 inch tab will trim
off
any load and only deflect a very small amount keeping drag to a minimum.
However in an aircraft with completed and painted surfaces I have used a
spring system.
I usually try to find easy ways to make dumb simple, bullet proof
control
systems that can't be goofed up.
Here is an item I designed, built and installed on a customers aircraft.
It
uses a simple spring set on either side of the stick with a mac servo to
pull left and right on one side and the other side has a simple bolt up
system. The servo can be replaced by a screw or lever system with a
locking
ratcheted lever. The bracket on the stick is .060 minimum 6061 T 6 bent
on
the grain. I normally install autopilots in our aircraft and the roll
servo
goes under the seat or in the tunnel and attaches to the bracket also.
The
trick is getting the spring and servo arm both attached. Break out the
OR
spacers on hand and nuts, bolts, washers and patience.
The spring rate is the tough part. Don't get it too tight or it
stiffens
the stick too much. At the base of the stick cradle, you only need
about 1
pound per inch max to trim a well rigged aircraft. I prefer springs
that
are 3 inches long. Use any length you want but make sure the extensions
and
hardware combination you use to attach to the servo or lever cannot
bind.
Without a trim servo motor or autopilot servo it is very simple to do.
Autopilot servos have no trouble with the system.
The next item that this requires is a simple fiberglass box cover so you
can't step on it... 3 layers of bid with a Reduxed angle on the floor
and
seat front keeps the cover set in place, but I glass or bolt in the
attachment brackets to assure that if stepped on it doesn't move.
Obviously
the cover has to have a U in the center to clear the stick.
I don't have photo's as they are the property of my customers, but it is
pretty simple. I prefer not to have an autopilot so that simplifies the
trim. Works too.

Bud Yerly

I would be cautious about any radio controlled =EDtem.as
<http://xn--tem-qma.as> I recall they they work on common frequencies.
When you are flying a radio controlled aircraft you have to ensure that
all
flyers are on different frequencies and everyone has a little banner to
indicate what frequency they are using.

Hi Alan
You could probably go blue tooth for control, just use your smart phone.
I
installed a Ray Allen servo in my aileron with the top being flush with
the
top and the control horn exits the bottom. I have it controlling a piece
of
hinge on the trail edge of the aileron. Not a great shot, left aileron,
view
in 600 you can see the bottom of aileron:

Don't forget you need to balance the aileron after you fool with it. I
don't
know how keen I would be to use a Lithium Polymer battery. For capacity,
cheap, readily available and a very low self discharge, I would go with
a
quality alkaline. keeping them it as far forward as you can. Tungsten is
heavier than lead, so you could try and find foam plugs in your
balancing
arms, or just drill and insert rods of tungsten (unless you can locate
some
depleted uranium rods surrounded with stainless steel). Put a switch
that
is easily accessible to turn it off and some sort of battery indication
you
can check on your pre-flight.
I know Steve D. was fooling with altitude hold:

Wonder if they make wing leveling too? Hmm, if you made a minimalist
wing
leveling tab, you could just leave it on wing level all the time when
flying, it would always try to keep wings level, then when you want to
bank,
you could easily over ride it!
