The maiden first flight Return Home landed just over a foot, which is insanely good.
Head Lock Mode
I have never used to be a fan of Intelligent Orientation Control aka Head Lock mode, but have begun to appreciate it as alternate way to return home without GPS. Using compass, forward is forward, backward is pulling back, left is left, right is right, regardless of which direction the aircraft is facing. However, Head Lock mode is relative to where you are standing during take off, so if you decide to walk across the street and face the opposite way, you may just get confused with the direction you need to face.

Calibration
Find a flat surface, preferably concrete, not grass to do calibration.
Power on radio and than quad. Best practice is to not move or shove your LiPo cables until the quadcopter has completed it's bind and self-leveling, or better still wait for the GPS lock. Leave the wires alone!

1. When you change venue a long way from your last flying location (greater than 100 miles).
2. When your quadcopter is drifting or rotating in a "toilet bowl effect" fashion. The inclination and deviation has to be corrected through compass calibration. The inconsistencies between GPS and compass will cause that swirling motion, in a tug-of -war for direction.
3. After a firmware upgrade, as it may carry the factory magnetic values.
Horizontal calibration
Lower the throttle stick and toggle the Head-lock switch for about 3 times. You should see a solid green indicator
Rotate around 2 times, horizontally and ensure the horizontal green indicator always stays on.
Vertical calibration
Lower the throttle stick and toggle the Head-lock switch for about 3 times. You should see no lights
You should see a solid red indicator when your quadcopter is vertical. Rotate around 2 times, keep it vertical and ensure the vertical red indicator always stays on.
Lower the throttle stick and toggle the Head-lock for about 3 times to save your new compass magnetic inclination and deviation values.
I found that completing an Auto Take Off is one good way to perform a pre-flight check, to ensure the quadcopter is behaving properly. If it begins to drift off to the side and not hold it's position on take-off, I will land manually immediately, inspect the quadcopter, the gps, the extra weight center of gravity (CG), recalibrate if needed.
