Pitch and Roll Auto Pilot Servos

I elected to install a two axis Dynon auto pilot system, (pitch and roll).  Perfect for holding altitudes and headings.  Turns using the heading bug, or route changes while in AP mode, will be assisted with the pilot's foot on the rudder pedals in the appropriate direction to compensate for adverse yaw.

The roll servo is mounted under the pilots seat on a .050 aluminum plate.  The plate is secured using adel clamps.  Dynon provides brackets in their AP servo mounting kits.  The following pictures show the plate I fabricated and the Dynon provided bracket.









The pitch servo requires a little more "beef".  I installed a .050 aluminum doubler under the floor board.  Then took another .050 alum plate with angles to create a base for servo bracket.  

This picture shows 1/8" thick angles attached to the bracket mount.  Angles are approximately 14" long for stability.  



Next, I attached the angles to the .050 plate (covered in carbon fiber vinyl for a nice finish)




Both AP servos mounted
