Marc,
I found your concern about the A/P intriguing. Might I ask, in your opinion, do you not trust that you can override the servos in that situation?
I did have an incident about two years ago, right after I first installed the autopilot, that might be relevant. I had installed an A/P disconnect/CWS switch on my sidestick, as a pinky momentary toggle switch, (similar to what I had in the F-4). I installed it on the shaft of the sidestick, with the top of the toggle lever just below where my pinky would normally rest on the stick. Initially, it was a little bit too high, and before I moved it, I inadvertently activated it with my pinky without realizing it. Once this happened on final approach, about a mile or so out.
As I'm sure you know, (with the Hold to Engage set on), if the Dynon A/P is not engaged, toggling the disconnect switch (for 2 secs), causes it to engage, in roll mode. When this happened, although it was an adrenaline rush as I did not immediately realize what was happening, it was not hard to overpower the servos and maintain control. It was only after I was safely turning off the runway and it happened again that I realized what had happened and resolved to move the switch to a lower position on the sidestick.
