Sorry Dave I should clarify, Yes you would place the joystick Circuit Board into the housing, however I use an existing Arduino that I have in my cockpit. I have 5 Arduinos running for various button rotary and toggle systems.
Two axis -One for collective up down the other on the bottom
-Second under the collective
I didn't like the fact that the collective mounted on the chair was banging into the side of my cockpit. So mounted direct to cockpit.
Mounted by a couple of screws through the cd housing. I love building these things
