I just went through this thought process on a recent plane that came with
carbon tail pins. Though light, they won't take the abuse that steel will.
The stabilator is probably the most important flight control and a concession
made to the weight gods is probably a good idea here. It has happened that in
the heat of the battle, a plane was smacked in for a million point landing,
and it wasn't until the subsequent launch that the broken stab pin was
discovered. Big splat ensues. Another advantage to metal pins is that they
can be kinked, which makes stab retention possible without glue or set
screws. Anyway, I did have the right diameter music wire for the pivot pin to
replace the carbon, but not for the rear drive pin. I found some laying
around that was too thin, so I had to bring it up to spec by sheathing it in
a brass tube. I thought "Hmmm, one could probably sheath carbon in a brass
tube, save a little weight and gain a little durability. About the kinky stab
retention, though, I don't know..."
