I too like my Spektrum DX4S, even though I read lots of people on forums bashing Spektrum. That being said my only other radio experience is with my first RC's Traxxas TQi radio - I realize thats a big enough change.

I am very interested in getting this DX4R pro when it comes out, but I can't find much information online as to what the differences of the DX4S and the DX4R Pro will be aside from 11ms to 5.5ms and 50 memory profiles from 30. Can anyone who knows more about radios than I do tell me what other differences there are and if it would be worth the upgrade?

Thanks
