It's no coincidence that the military has incorporated control interfaces on a lot of new equipment that is based on video game controllers like the PS series and Xbox. A whole generation is very familiar with it. Just Google "military equipment uses game controller" and you'll see what I'm talking about.
Traditional RC fliers and us older dogs don't seem to have much of a problem with the 2-stick controllers. So many game controllers seemed to lack the proportional control needed for precision input.
Great point! It also depends on what purpose you're flying the drone for. If it's for fun, this may be acceptable, but something where you need precision, it doesn't seem like this would cut it right now. Maybe once they're a few generations in and work out the glitches.
