The H-480 has had CCC from the beginning, which is a very crude method of establishing waypoints. It works, but carries with it significant penalties. Using CCC the aircraft must first be flown to the desired location of a waypoint, saving that location, and moving to the next waypoint position and recording it. The mission profile is continued using that method until deemed complete. The aircraft is then flown back to or close to the beginning of the generated flight plan and initiated by the operator to be flown seamlessly using the autonomous functions of the software. A CCC mission cannot be set up with the aircraft on the ground, unless that mission had been previously flown, generated, and saved to be recalled later. There is no map or grid available to follow. A major detractor of CCC is the aircraft has to fly the mission to create the mission, and a large amount of battery capacity is consumed in flying and setting up the mission. Often a CCC mission must be generated on one set of batteries and flown using another set of batteries because too much battery was consumed in mission generation. Re-calling a saved CCC mission often requires previously saved waypoints be checked for positional accuracy by flying a test mission for verification. Tuna's UAV Toolbox blows CCC out of the water and is a much better tool to use for those that want to have a go at mapping, or waypoint missions in general. The only reason not to use it is that people want to be able to do any and everything for nothing and spending a few bucks on an app and learning how to use it is above their capability. Makes me wonder about the quality of the maps they create as that quality will be established by the captured data and the sophistication of the software or service used to process the data.
I've read where a few people have used the 920 profile and bound their 480 to it. Some say they have done this and successfully utilized the 920 waypoint function to fly mapping missions. I have yet to see product generated from those people and lacking proof to the contrary I'm a bit skeptical of their claims. Some say the 480 is stable when flown under the 920 profile while others say it is not. Since I don't know precisely where the PID's for the aircraft types are stored in the system I have a lot of doubts about stability. As the 920+ uses the same FC as the H-480 I don't understand how one flight controller can have two completely different sets of tuning parameters maintained within it. I do understand that a given FC can have different performance profiles but the differences in size and weight between a 920 and 480 are immense, as are the motor/propeller response times. That doesn't begin to consider the differences in aircraft mass, where the 920 is much greater and varies depending on how many batteries are used. My best guess has those using the 920 profile to fly a 480 putting their aircraft at considerable risk.
The 920's waypoint flight feature has provisions for downloading a limited amount of area from Google Earth, when internet connectivity with enough bandwidth allows, for later recall. A flight plan is generated by the user dropping waypoints with altitudes where desired, and allows "smoothing" the flight by selecting a curved intercept of the waypoints. Waypoint altitudes are also user selectable. Associated with waypoint generation are choices for where the camera will look and what it will do when arriving at a waypoint. The user has to set the tilt angles for each waypoint, which can be a bit tricky in guesswork. There is also a user option to establish what the 920 does after completing a waypoint flight. When building a 920 flight plan the aircraft is not being flown in the process. The waypoint function was designed and intended for cinematography type operations, not mapping. Sure, you can swap out the CGO-4 or other 16Mpxl to 20Mpxl 920 camera for a 12Mpxl CGO-3 to obtain geo tag data but hopefully you'll have changed lenses on the CGO-3 for something better than the stock lens.
I've never used the flight sim and have nothing to offer in that regard, but I can certainly understand staying warm inside over being cold outside
