Gene ... your write-up sounds good, can you please send a picture or
sketch of the rear rudder pedals and trim direct and off line? My 4 is
all opened up right now so putting in rudder pedals is my next project
... I just need to know what works.

OK, for you out there that have rear seat rudder pedals, it is an easy
task to install a rudder trim...Get a turn buckle and a medium strength
spring, and (you determine the size of each to fit your situation) hook
the turn buckle to the right rear pedal, and the spring where the rear
pedal PUSH ROD goes through the bulkhead.
To operate, push the right rudder pedal with your size 12 until you
get the "ball" in the center, or where ever you want it, then start
cranking the turn buckle to tighten the spring (this PULLS the rear
pedal forward, and the right rudder forward) until you can remove your
size 12 from the front rudder pedal, and maybe tweak it if necessary.
I know your thought now is, "suppose I forget it all in the traffic
pattern," no problem, the spring might cause a little more pressure to
be applied to the right rudder, but it works fine...If you think of it
in time, you can reach down and disconnect the spring without even
looking.
So you don't have rear rudder pedals?..No problem, get a aluminum rod,
attach one end to the right rudder pedal right flange, drill a hole in
your right side bulk head and install the rod through it, allowing
enough length to work back and forth...For a long flight, get the "ball"
where you want it, and IN THE FRONT OF THE BULK HEAD, attach a small
pair of locking pliers to hold the rudder in place...LAUGH IF YOU WANT,
but I used this for years to go to OSH and LCL before installing the
rear seat rudder pedals (and never had right leg limp after
arriving)...If you forget about it in the traffic pattern, KICK THE "DOG
POO" out of the rudders and the pliers will fall off...(provided you
didn't crank them too tight!)................Hope this helps someone out
there, good luck and
.....................CHEERS!!!!...............................Gene Smith.

Jerry,
Gene's idea is great but is alot easier than that. All you need is a simple horseshoe
shaped piece of .040 aluminum 3" wide. Drill a hole in one side and attach
a small piece of mini bungee cord with a hook on one end and attach the
cord to the horseshoe. You simply place the "U" in the Horseshoe over the rudder
cable (next to your right thigh) with pressure on the rudder inflight with
the hook over the edge of the fwd fuselage bulkhead. Release the pressure and
voila' the cable pressure over-center moves the U to one side thus holding the
cable where you put it. Same principal as a strap for climbing palm trees...:)
Very simple, cheap and works. I'll take a picture for you and post it...
