I started looking at this, but I'm disappointed in finding that it won't go down below 11ms for frame rate. According to Spektrum's website for the product it only does 11 or 22. Even the older Spektrum's that I have use faster response times of 5.5ms.
So, at least with this initial offering, it looks like the choice is:
1) Stay with DSM2 and 5.5ms response times, but risk interference
2) Switch to this and DSMR to deal with interference, but loose responsiveness
I haven't looked at other radio systems to see if they went through something similar, but this certainly tells me I won't be upgrading anytime soon, as I don't have interference issues with DSM2 at the locations/tracks I drive at.
