I'll be doing a review here on RCG of the new 2.4ghz DX8 transmitter, keep an eye open for it soon. Some of my favorite features of the DX8 so far are:

* Timer start on throttle up
* Vibrating timer (the whole box vibrates just in case you miss your countdown beeps)
* "wheel" style selector
* Telemetry
* Awesome 'feel' in the gimbals
