I have been interested in the mechanical trim wheel/spring cartridge system
Dick Reichel has produced as an alternative to the electric servo elevator
trim tab std on the Legacy and Mk II 360. The main reason I like it is
elimination of the possibility of runaway trim. Say you are coming downhill
deep in the yellow and the trim switch sticks - - - - down. I know there
are some good disconnect systems to recover from this, if you have the
presence of mind to react quickly enough.
Another reason is the ability to easily fine tune the pitch trim, my RV6
usually has to be bumped up-down-up a couple of times to get it right.
Again I know you can get a two speed electric trim, attach the MAC slow down
box, etc..
I have asked both "The" Don and Orin if they have tried the Legacy at cruise
speed with full up or down trim to determine control pressure, they haven't.
To me the mechanical trim seems to be a simpler less trouble prone system.

Dear Steve,
I've just completed a new batch of trim wheels. Give me a call. I
would like to see you put one on a Legacy; I think the mechanical trim
is a better approach than the electric trim tab. My cell phone number
is 805-455-4296 if the other phone doesn't answer.
Regards, Dick
