Control Stick Wiring (Electrical)
5.3 Hours

Today I got to work on the control sticks. I cut the pilot side stick shorter to make room for the stick grip and drilled the hole for the grip attach.

I cut the copilot seat stick to length and drilled it for the grip attach. I also did an old SB from Van's that has you drill the stick attachment for a bolt so it's impossible to pull the copilot stick out inadvertently (something that has happened).

Then I did all of the wiring for the stick grips. They both have a PTT button (for radio transmit), autopilot disconnect button, and pitch/roll trim hat. I still need to connect the autopilot disconnect circuit together.

I also added the trim power/ground inputs to the GAD 27 so it would show me when I was testing the trim hat on the stick grips. I also discovered I had wired the copilot roll trim wire backwards, so I had to take that connector off the GAD 27 and switch those contacts.
