Ability to designate an area of the display as the tracking selection and then select the subject in that
area for tracking by using control functions on the controller. Using a display is difficult unless you use a display shade. Once you install that, it's difficult to reach the display to use functions.
So, designate an area of the display as the target area before flight. Then select that area during flight using on of the switches on the controller with out having to reach the screen. Using the controller switches is much easier than reaching the display. One possible switch on the controller for use would be the C1 or C2 switches on the bottom of the controller.
Audio warning when tracking is lost.
GPS tracking as an option. When used, should make tracking more reliable for smaller targets and in
varying lighting situations
