Using the advanced features in NAZA-M on the DJI Phantom controller allows one to fly in the Course Lock and Home Lock modes. In order for that to happen settings must be made in the Phantom Assistant software. While using the NAZA-M mode turn on the IOC (Intelligent Orientation Control). When the IOC is turned on the S2 switch in the top position means off.
The middle position is Course Lock. The advantage of Course Lock is you can start Course Lock right as you take off. Using the stick controls to turn the Phantom will still direct the Phantom as you expect and want — where up goes opposite from you and left goes to the left etc.
The bottom position is Home Lock. Home Lock is great because it comes back to you and the directions are still as you expect and want — where up goes opposite from you and left goes to the left etc. The disadvantage to Home Lock is it likely will not work till the Phantom is 30 feet away (10 meters).
If it seems the S2 switch is not working, turn the S2 switch to the off position and then back down to Home Lock or Course Lock. Then try the directions again. The Phantom Knowledge program demonstrates how to set up these features and explains how they work. One of cool features that is demonstrated is how to change the “base” direction of Course Lock while in the air.
