FPV Flying is a difficult challenge due to potential radio frequency interference issues when combining a Datalink GPS system with an FPV video downlink system. On top of that your MR would also have to simultaneously use your RC radio control system.
GPS GCS Datalink systems were designed to use virtual 3D views from Google Earth to get around these issues.
To modify the software you would have to get a copy of the source code from the manufacturer as the controller contains only the object code which is typically a string of 1's and 0's.......(ANSI C code) which would be extremely difficult to decipher and reverse engineer.
You would also have to fight your way through the firmware encryption issues including serial number matching as well as modify the appropriate version of the Assistant software. That would then isolate your sw/fw development for free software/firmware upgrades as a result of free added features and/or debugged issues. There are also legal copyright infringment issues etc. My philosophy is to pay for what others have rightfully earned.
Your best solution would be to develop your own code, firmware etc. which is not too difficult to do.
Try DIY Drones and work with the free and open source material their developed for the Arduino and related controllers.
The open source world imposes tremendous pressure upon DJI and others to offer their proprietary products at a competitive price.:cold:
Thanks for the answers.
Of course I have to see how long the copterbattery lasts etc. That is- as I see it- the smallest problem. The user manual should reveal the most info on speed, battery life, ... These have just to be controlled.
However. What I actually meant was, if there is a possibility to 'modify' the software in a certain way?
PS: I want to use the copter for FPV flying.
