Copter-3.4-RC5 Testing - Disarmed during guided takeoff and barometer not resetting to 0 upon arming

I tested out 3.4 RC5 on my F550 Hexacopter today. The testing went well except for these items:

1.) I had my MOT_THST_HOVER set initially to .2159392 and had MOT_HOVER_LEARN=2 in RC2 and it worked fine. I upgraded to RC5 and attempted a guided takeoff and while hovering the copter cut power. It looks like MOT_THST_HOVER either got changed during the upgrade to .3350102 or was adjusted in flight.

I changed it back to .20 and conducted multiple guided takeoff flights (and AUTO and LAND) without any incident:

2.) It doesn't look like the barometric altitude is getting reliably reset to 0 during arming. I noticed that uploading a new mission did reset the altitude for some reason.

3.) It still doesn't gracefully handle the situation where there is no R/C. I still have to override Yaw on guided takeoff and Yaw, Pitch and Roll on landing to trimmed values.
