I have looked at that and adding a plate to the
bellcrank at the end of the flap actuator in the 320/360 can give an attachment
point for the coupling spring right next to the elevator push rod.

You will need a bit more design in the 320/360 as the flap actuators
operate approximately 90 degrees to the elevator push rod whereas the 235
flap mechanism is a torque tube with any attached arm acting parallel to
the elevator push rod.

I
copied his installation, and after a few adjustments to spring
rates
and engagement
point, I have to make only small trim
adjustments after lowering or
raising the
flaps.

Previously,
the full range of adjustment on the mechanical spring trim
was not
quite enough
to cover the full range of operating speeds. The
installation is very
simple, consisting of a
spring mounted in the
center console. One end is attached to the end
of the flap
actuator
piston (in a 235). The other end of the spring is attached
to the
elevator pushrod.
