1. Fix autoyaw to 0 attitude on takeoff post launch.
2. An error condition abort now properly disarms and continues to contrain thrust and stabi during disarmed state.
3. Increase thrustdown time from 2 to 5 seconds on an error condition (e.g. if 3 m deviation from takeoff position on NE).
1. Allowing arming in pathplanner
2. Takeoff activation requires throttle to be above 30%
3. Takeoff occurs at the current/actual position and rises vertical to the settings altititude.
4. The details of the takeoff waypoint are effectively ignored - this is a simplicifcation to avoid having to have pathplanner inject a flyvector command from the current location to the waypoint
5. We hard code the condition check for autotakeoff as only one mode is supported.
