3DConnexion just released a new wireless version of a 3D mouse (link). These things are awesome for CAD but I think they could be a great way to control a copter. I would love to see support for these 3D mice on mission planner. This could also be a good way to control our copters when using a tablet for telemetry. It can provide the feedback we don't really get from virtual sticks. I just want to get away from clunky RC transmitters soon.
