A recent test in one of the UK model magazines said that the JR DMSS system was the best set up. Mine has been faultless. Just like my DMS-2 JR systems. Anyone can have issues with any system, the installer has the biggest factor. How they handle fragile components, connections etc etc. You need to understand the system, its needs and then it will probably work fine. There were a lot of idiots slagging off Spektrum when it was released as they didn't understand the battery requirements, didn't understand what had been happening on their Mhz radios for years, but were "getting away with it" I still use the earliest AR 7000 Rx's from Spektrum with the slow update...in a 200mph EDF and its never missed a beat because I put the Rx, remote in the best place and used a PB switch and li-po
Go for what you like, understand, can get help with...
