Yea, that was probably the same AR600 rx that I had an issue with. My biggest issue with Spektrum is that they did not seem to get pro-active about resolving the issue with a full on recall. There was a well documented issue with that specific model. I can't speak to the FASST technology. Other than that one incident, I have been happy with the DSM2 and DSMx radios. I will say that on my 99" Dynaflight, I upgraded to a DSMx receiver that has a backup sat receiver, just for a little extra security. That plane can easily fly over 1k' and lost signal could be a huge problem.
