Over the years I have used several different radio systems and have settled on the Spektrum DX7 for my current flying models, as well as my Phoenix RC Flight Simulator. In my opinion, two of the biggest advances in Radio Control technology in recent years are 2.4 GHz Spread Spectrum technology which led to the second, which is Bind-N-Fly.
The only thing the DX7 was lacking was a backlit LCD for flying in low-light conditions. I do a lot of flying indoors in low-light situations and the LCD display on my DX7 is quite hard to see under those conditions. Through the use of Electroluminescent (EL) panels, the LCD display can be backlit and the results are very nice as you can see in the picture. An added benefit to the LCD lighting is that it is obvious when the transmitter is left on due to the backlight since it does not come stock with a power light of any kind.
