- Update assessAltitude() to return the altitude in auto takeoff as well as auto land code.
Code that duplicated the calculations has been removed.
- Make pretty & update headers
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).
