I am very pleased with the spring bias rudder trim I installed last summer.
It was easy to fabricate, install, and required no modifications to the
rudder. It has adequate range for high attitude climbs and fast descents.
Beats having to hold rudder pressure for long periods of time. I used the
aileron trim servo kit and installed it just behind the baggage bulkhead
against the bottom skin straddling a stiffener. An additional cable connects
to the rudder horn on one side, wraps around a pulley, to the springs at the
servo and back to the rudder horn on the other side. Pictures available to
any who are interested.

I'd love to see pictures! I've modified my -10 so that the rudder
cables hook to the pedals inside the tunnel, and will add a loop to tie
the rudder pedals together. The trim is the only thing left!

I had a lot of requests for pics so I'll post this to the list.
I used the same servo kit that we use in the wing for aileron trim, servo,
springs, assembly etc. I left a 12" gap in the cables for springs just like
in the aileron setup and that seems to produce adequate trim.
The pulley is a 3" dia for 3/32" cable. I put a keeper over the pulley so
the cable couldn't come off but I think it is redundant.
The bracket holding the pulley sits on top of F-1035 and under the elevator
servo mounting bracket see page 10-24 fig 1. I bent a flange on the sides to
make it stiffer.
I installed the pulley bracket and then assembled the MAC servo kit. The
servo and bracket are mounted about midway between the bulkheads and
straddling a stiffener using 4 flat head screws up through the bottom skin.
I used 3/32 7x19 s/s cable with MS20668 Eye Ends. At the rudder horn I used
a longer AN3 bolt and attached the trim cable below the original rudder
cable.
This was actually very easy to install especially if you had thought ahead
and the 5 wire cable was already in place. The dual cables at the rudder
horn aren't too nice but I didn't want to clamp onto the rudder cables
inside the tail cone for some reason. The new cables line up well with the
snap bushings and the original rudder cables. You can easily over-ride the
trim should it be necessary.
