That's weird that the Spektrum glitched. I've had a DX3, DX3.0, and now a DX3r and none have ever glitched on me. Personally, the DX3r has everything I need. The only thing that would have made it perfect would have been a data port for PC programmability and/or firmware updates.
Yeah, it is pretty weird, but it's happened a few times. I will say that our track has a few power lines running right over it and really gave my last Airtronics MX-3S radio trouble in a couple spots.
I've also been interested in some of those other features I've mentioned that the DX3.0 doesn't have.
