I spent a fair amount of time researching and planning the best way to do the stick grip wiring with the main questions being: wiring the push to talk to the audio panel and wiring the a button for go around mode to the G3X and the GTN 650.
The push to talk turned out easy with just needing to connect to an appropriate pin on the audio panel. The go around button will need a little more work requiring two small diodes to isolate the G3X and GTN 650.
The Tosten sticks have 8 switch functions. Here is my set up: trim left, right, up, down, push to talk, auto pilot (cws, disconnect and on depending on how long you the button), take off / go around and as an experiment I will be using one button to play / pause the music going through the audio panel! (I just found this option today.)
Some more details:
- Drilled 3 new wire pass through holes in the sub panel. I was very careful to cover and tape the electronics to keep metal shavings out.
- Added terminals to two pieces of 5 conductor wire for the stick wiring to the panel area.
- Ran the stick wiring forward and then temporarily attached the terminals to the switch wiring terminal block
- Connected the trim switch wires to the VPX and attached pins to the wires going to the audio panel.
