I currently have the Navaid autopilot and  the Dick Richtel trim system in my 320, they are both working fine.  Now I am considering installing the Trutrak altitude hold system (Altrak) and wonder if anyone has any comments, or knows of any competing products?  I would be interested in installation pictures/comments.

 

 

TIA
