Let me preface my post.. *** I realize that true dual op mode as designed by DJI cannot technically be accomplished without 2 controllers... KEEP READING!! *** I have had my inspire for 3 days now and made 7 flights. Before purchasing I debated very hard as to if I should get the dual controller mode. The opportunities it supposedly opened up seemed great especially for filming which is what I purchased it for. I ended up getting the single controller mode simply because I felt that I probably would be flying 90% of the time in single controller mode and I just didn't want to invest the extra $800 ($500 + tablet) right now for something that would sit unused. With each flight I have been tweaking flight/control parameters and learning new things on how I can control it to the best of its ability. Last night I started toying around with the ability to move the camera gimbal in any direction while pressing on the screen (Ipad air with .092 app) and then dragging your finger away from the point of press. This feature works freakishly well and it got me to thinking.. Can you have dual op mode without the second controller? As I debated getting the second controller I tried to envision how the dual control mode( with two controllers) would be used.. Here are two things that I figure are true but since I have not actually flown dual op/controller mode I could be wrong: 1. Since the camera operator would have control of the camera the pilot should NEVER fly FPV and only rely on line of sight while retaining good visual bearings of the physical location of the craft. 2. While the pilot would have the opportunity to look at the tablet on their controller this would probably not be a good idea AT ALL as it could easily lead to disorientation and cause extreme problems.(example.. the camera op is pointing the camera in the opposite direction of the direction of flight). With these assumptions and after using the touchscreen to rotate/pan the gimbal it got me to thinking that you could easily setup "dual op" mode with one controller and tablet using the following steps. Have your camera op stand close to you... Hand them the tablet(while it is linked to your controller via the usb port) and train them on how to effectively use the touch to pan/rotate feature of the gimbal. You as the pilot would pilot the craft while maintaining sightof the craft 100% of the time and only communicate with your camera op as to what movements you are going to make and how you would like the camera to move / shot to look. Honestly.. Without knowing exactly how dual op with controllers works but knowing how freakishly well the touch to pan/rotate works I could see this being just as good as true dual op.. Whatcha think?
