Ignore Disarm Command

ArduCopter Copter 3.6

Im having an issue where my hex is failing to disarm through the rudder command. It has happened a few time but I only have a log for the last time. The last time it sat at idle for about 10 seconds then went full throttle I was lucky to have been holding the hex down. Can someone give some advice on my

If you are in a guided mode, it will not disarm unless it thinks it is on the ground. Occasionally bad sensor readings will make the copter think it’s still in the air and not allow disarming. See if it disarms normally in stabilize flight mode.
