The Fly Sky FS-iT4 2.4GHz 4-Channel Radio System is loaded with a host of features that you will only find on higher-priced radio systems from other brands. It all starts with the FS-iT4's large, color touchscreen display that you can operate with your fingers or the included stylus. The screen uses graphics to show you all of your adjustments visually, allowing you to customize practically every parameter for each of the 20 model memory slots. Control is superb thanks to the second-generation Automatic Frequency Hopping Digital System (AFHDS2) and its capability to do both model control and on-board telemetry at the same time. Yes - the FS-iT4 includes voltage, temperature, and speed telemetry sensors in the box, ready to plug and play into the FS-iR4 micro receiver. As for the radio in your hands, the single rechargeable 3.7v 1200mAh LiPo battery helps keep the transmitter nice and light. Further driver fitment comes from an adjustable-angle steering wheel housing and two different handle grips (included with system).
