Bummer... I was hoping someone would have one of these by now and could give feedback.
I saw some pics online where someone opened up the controller and it showed a wire routing up into each antenna. I probably wouldn't do it, but I bet someone skilled enough could replace the existing antenna ports with a bnc type connector to be able to add various range boosters and/or larger antenna.
I'm not necessarily interested in increasing my range to any ridiculous distance due to battery limitation, I just want stronger signals in high interference areas.
