I had a Turnigy 9x, but now I have a Fr Sky Taranis, and it's well worth the difference.
The Taranis has more controls, and ones you really use. More three-position switches, better screen, and a USB connection already in place for firmware upgrades, and load/save model configurations. It supports sound files, so you can setup a model with audible warnings and info, and it has telemetry! The two-way communication that makes telemetry happen is used to tell you BEFORE your receiver gets out of range, and with the right hardware on your craft, you can see or hear when the voltage is too low, or any other data from your controller or "SmartPort" sensors. This radio also supports S.BUS for single-wire connections and additional models to get up to 16 channels at one time.
The Taranis has a "module" built inside, and port for another, like a DSM2 module, so you can quickly switch between a DIY plane and a PNF quad without plugging anything in. The native ASST (spread-spectrum communication) is supported by many different receivers with three to sixteen channels, and different sizes to accommodate any craft you can find.
I really cannot see buying anything else!
