I follow that topic because I have a serious problem related to disarming with AC3.4.
I'm on it since several days and i begin to go nuts!!!
First I thought it was a refresh rate of GPS Issue, but it seems to not. My copter (huge octo, my loved tool for work since 4 years) does not disarm by itself after touching the ground. I always used auto landing, and it cost me a propeller set the first time I flew with AC3.4.
I Upload a log, you can see I wait for disarming (while still in poshold) for 3-4 seconds, then go back to stabilize to disarm manually. Even withouttaking off, if I engage throttle at 10% for making the props spinning, then go back to throttle down, it does not disarm.
