You'll likely get many arguments as to PCM vs. DSS. That said, I was a loyal Futaba guy until recently. My son got a heli version of the Spektrum DX-7 for his electric Mini UltraStick airplane. Both the heli and the aero versions have the same programming but the heli models have different (and some say more convenient) switch positions as well as a non-ratcheted throttle gimbal. He loves it!

I just bought a Futaba 9CAS system with the synthesized modules 18 months ago to upgrade from my workhorse 6XAS radio. That said, I've now just acquired a 2.4GHz JR X9303 and a rash of 2.4GHz receivers. My 72MHz gear is being put out to pasture.

I believe the DSS 2.4GHz market is doing to the 72MHz FM/PCM market what digital compact disks did to the vinyl LP market in the 1980s.
