This might sound like a strange question, but is it possible to use two controllers simultaneously with the DJI Phantom 2 Vision+? I know the Inspire 1 has this feature included by default, but was thinking this could be handy for the Phantom as well. With this in place, an expert could quickly take over control in case a novice is loses control, much like the old Driver's Education cars. Has anyone tried this yet? Would it be as simple as just buying an extra remote and registering it?
