I'm planning a "stick enable" switch with three positions: Left, Both, Right. This can be done with a SP3T switch. I drew the wiring that it would require at some point but I don't know where I put that. You can also use a magneto switch to selectively ground your stick buttons.

I want the option of turning off the left seat stick in case I decide to fly from the right seat and have a passenger in the left. I decided I don't really need the option of turning off both sticks.

I consider this post by Ed Wischmeyer to be one of the best I've read on the subject of determining which functions earn their way onto the stick. Simpler is better in the long run. Also, in my construction blog there is an entry that captures my thoughts on stick buttons for my RV-14A. I used Ed's logic to assign functions to the various buttons.

When you're musing over stick buttons, don't forget that they do not exist in a vacuum. Make sure you look at the system as a whole. Where do you want to position the flap switch? TO/GA (if included)? Think about how you're going to operate the aircraft. What are your flows? How are your hands positioned during takeoff, climb, cruse and landing? What functions do you need to perform in each of those phases of flight?

If you go through this process, you'll end up with a simple layout that is less prone to operator error (e.g. unintentionally bumping the starter button).

Good luck. I look forward to seeing what you decide.

Pet peeve: "Lose" (rhymes with "booze") is the opposite of "find". "Loose" (rhymes with "juice") means "not tight".

Default Pitch Sensitivity in cruise

There is another reason to mount the passenger's stick buttons on the panel. I learned a long time ago when flying with a friend in his 6A to Sun'n Fun that operation of the stick mounted PTT could cause a gain or loss of 20 or 30 feet in altitude.

At cruise the RV's are sensitive in pitch. If the passenger is doing the radio work while the pilot is flying, it just makes more sense to me to have the PTT (and any other switches) on the panel. Otherwise, let the right seater be PIC while he/she transmits.

YMMV
