If you are ugrading to the DX6e from a DX6i you will surely enjoy this new radio. It has some very nice featuresone of which I wish my DX18 had. The On/Off switch is awesome.
Push to Power On
Push/Hold to Power Off
The next great feature is the ability to change gimbal spring configurations simply by moving a slider switch on the back of the transmitter. If you're an airplane guy who has quads and want to fly them with the throttle stick spring loaded a single slide of that switch gets you into that mode.
