REFLECTOR: TruTrak Automatic Trim

[Bob Jackson]

No, that's not the way the TruTrak is supposed to work -- in fact, if you
don't have the auto trim box, the TT display will show a special 'moving
ladder' symbology when it's out of trim.  

And the unit DEPENDS on the pilot to manually trim the elevator until the
'moving ladder' symbology goes away (which means that the elevator is back
in trim, and no pitch spikes when it's disengaged).  The TruTrak autopilot
does not prevent the pilot from trimming when it's engaged -- at least not
our model (DigiFlight II VSGV).

I put one in about a year ago. Works pretty well. It doesn't go to zero
pressure trim, but overall good. Well worth it for me. Without it, you need
to guess and remember to trim. I used to hate the AP disengaging. At 350,
it's well worth it. It also disables the manual pitch trim when the AP is
engaged - making manual trim impossible until the AP is cancelled. Andy ----

Anyone flying with TruTrak's Automatic Trim module? If so, how would you
rate it's function and service so far? I see it has come down from $1100 to
$350 and was considering adding it to my Velocity's pitch trim servo. Bill
