No bird ever flew nonstop from New York to Tokyo, or raced 15 miles high at triple the speed of sound.                                                                                                   
  But birds do something else.
  They do not conquer the air; they romance it.

Some decisions in life are bare of any obvious logic

 

The Dynon system communicates through the Dynon network. There are dedicated network cables identified as SV-NET cables which the Dynon system uses to communicate between the different components and devicdes. The cables exist in different lengths and the short ones have the connectors pre-installed in both ends. For the longer wire runs, only one connector is pre-installed and the other one left off to facilitate routing through the different conduits, grommets and bushings.   You can install multiple SV-NET-HUBs which serve as connection and routing points for the different SV-NET connections.

I installed one SV-NET-HUB on the cockpit side to connect the control modules, HDX and EMS.

Today I installed a second one on the F-728A bellcrank channel which will serve as connection point for the ADAHRS SV-NET cable and the SV-NET-SERVO that feeds the autopilot servo's.

The back side is close to the bellcrank channel but interferes in no way.

Next I routed the 3 nylon wires that lead into the ADAHRS module for AOA, Pitot and Static air input

I ran the long SV-NET cable from the hub behind the panel, through the center conduit, F704 and conduit underneath the passenger seat towards the new SV-NET-HUB on the bellcrank channel.

Mission accomplished, cable installed with some service loop.

I had some time left and started playing with adjusting the elevator trim pushrod. The trim is at 0° in the neutral position aligned with the elevator skin.
In the Flight inspection and test part of the manual on page 15-2 you can find the maximum  deflection of the trim tab.

Maximum up is 25° and maximum down is 35°

 

In my first attempts, I exceeded these values. Too much up trim and way too little down trim soo far. This will require more tweaking in the near future.
