Copter 3.4-dev disarm in midflight using pre-release firmware

There has been at least one report of a vehicle flying Copter-3.4-rc1 and disarming in the air when switching from AUTO to LAND mode. (see report here).

The cause is not yet clear but I recommend people be very cautious flying Copter-3.4-rc1 in fact, I would go so far as to recommend testers wait until we get to the bottom of this and release Copter-3.4-rc2 with a fix.

Thanks for the testing and patience.

Sorry, this issue was from a version of Copter from before -rc1 was released.
