We have so far not test the return-to-home feature. We would prefer to perform this test in a very open area with no risk of the drone colliding with a person or property.
Eve has demonstrated very nimble "headless" flight. In headless flight, the forward direction is defined by the direction the operator is standing. Thus forward is always away from and reverse is always towards the operator. This makes for some great flying as you can yaw the quadcopter around while flying in a straight line.
The other IOC mode defines forward/backwards based on an intended flight path (think point A to point B). We may post results on this in the future though it's perhaps not as interesting or useful.
