as the Parrot Disco flightplanner freeflight.pro is really not useful some questions:
Is anyone aware, if there are any plans to support Skycontroller 2 on Ardu Mission Planner?
Will the Parrot Disco 4G hack get support?
Will the FPV of the Disco work in Ardu?
Any timeframes on this?
Keep up the good work.
It has nothing to do with mission planner .
Your questions are really;
Will Ardupilot/ArduPlane handle RC input from Skycontroller2 ?
And FPV video...
Fran, this is possibly not the best place to get an answer to this question. If you haven't already, I would suggest you try the Ardupilot forum, possibly under the Arduplane subforum.
Also, if you have some cash to throw at this, you might consider hiring a developer to look into it, have a look at the list at the docs page (it looks as if a lot of the dev work on the Disco was done by Andrew Tridgell).
