| Subject: | RV-6A rudder trim tab |
I am priming things. I gather that most planes have a small
rectangle of sheet aluminum glued/taped to the trailing edge of the
rudder and this is used to make a tiny trim adjustment to the
rudder. I can't find a reference to this in my manual. Can some one
advise me of the size of this this and what thickness is usually used
for it?
Thanks,
---Tom Sargent, RV-6A, almost ready for the color coat.

Hi Tom,
What worked for me was a balsa trailing edge for model airplanes purchased
from a hobby shop. I used one about 1" wide attached with double stick foam
tape. I started with one about 8" long and finally trimmed it to about 5-6"
after several trials. I have seen wedges of various materials, attached in
various ways on RVs. I am sure the length needed varies with the individual
plane. So, it is an engineering experiment to adjust the length as needed
until the plane flies with the ball in the center at cruise speed. It is a
separate problem from a heavy wing correction. I used a balsa wedge from the
same stick as my final rudder trim and painted it the color of the rudder.
The foam tape was still intact after three years and 140 hours.
Regards,
Richard Dudley

Tom, most use balsa wood and size is determined by trial and error.
Most I used are about 4 to 7" long by 1.5" wide. After trying in
flight and size is determined attach it with JB Weld. and away you go.

Oops. Make that a tapered pc of balsa starting at 1/8" and going to about 1/4"

Well, I can't really answer your question about the tab size. A fixed
trim tab will only be truly effective at one certain airspeed ..... and
is usually set for the cruising speed most used. I'm building a -10,
and am going through the 'trim tab' scenario as we speak. There's been
a few emails with pictures etc. on the -10 list about bungee (spring)
trim systems .... some folks are really creative. I don't like those
solutions, so I'm going to attach a hinged tab to the trailing edge of
the rudder and move the tab with a model airplane servo. I'm in the
process of creating the servo controller with a 555 timer in pulse width
modulation mode.

Tom,
A few years ago, I installed this simple wedge now sold by Avery. Trim its length
in 1/8" increments and test fly until you are happy with the performance.
Can be epoxied into place. My wedge is attached to the rudder with double sided
carpet tape, works fine.

Why would you not want to use a small spring attached to the proper rudder
pedal?

I tried that. Spring amount that was good at cruise was way too much
at low speeds. I changed it out for the wedge.
