Do you have the sparrow strainer installed?

  While at high speed cruise (165 kts - 8500 feet - 2650 rpm) my trim is pretty much all the way up - if I am by myself. Two people, no problem.

  On high speed descent when alone, over 170-175 kts, then I am out of down trim. So I just add some forward stick pressure - or slow down a bit (less than 155 kts).  Before take off, 1" elevator down when alone, 2" down when a front seat passenger is on board.  Then as speed increases toward cruise, the trim goes toward more down.  

  I have considered shifting the trim actuator front pivot a bit forward to improve the cruise descent, but then I won't have enough up trim with two people up front and I'd have to be pulling back pretty good at rotation.  So I have decided it is best where it is.  It is installed pretty much like the 1999 manual - no changes to the ? spring. ( I don't think this has changed in the on-line manuals).

    This is where I do need the experience of those flying!

     

    When flying at high speed cruise ... do you find yourself needing nose up or nose down trim?  If you need to trim "nose down" ... what is the most deflection you need on the elevator (from neutral)?

     

    When landing I assume you need nose up trim, again ... how much deflection from neutral?

     

    Thanks much.
