Can any of you guide me with some good designs that I could use as a
starting point to build? After flying the Cessna’s for quite some time,
I am pampered by the use of the trim wheel and want to build something
close to it for my Firestar-2.

I built a simple bungee trim for my UltraStar.

I have aluminum trim tabs on the elevators, set to a slow cruise (about 40
mph) on the theory that I might survive a landing at that speed if the
elevator linkage broke. The bungee adds nose down trim, giving me just
enough for a shallow dive when the front tanks are nearly empty. What you
see in the picture is a loop of bungee cord (the black and white striped
lines), which attach to the elevator bellcrank at the rear and a piece of
cord at the front (the red sleeve covers the knots). The cord goes around
a pulley attached to the fuselage frame with a cushioned tube clamp, thence
to a jam cleat (also attached with cushioned clamps) where I set it as
required. Pull back on the line for nose down. Of course a Firestar is
different but the idea would be the same.
The bungee, pulley, cleat, and red ball on the end of the line are all from
West Marine.
