The FS-iT4 is Fly Sky's newest 2.4ghz radio system. This Fly Sky radio is loaded with tons of features that allow the user to easily configure their radio control model. The iT4 is capable of storing 20 models in its internal memory and has the ability to graphically represent all trim, exponential, and dual rate adjustments. The graphical representations are extremely useful in depicting how the car will react to the parameter changes. The switch and trimm buttons surrounding the steering wheel are fully programmable allowing the user to program each specific button to do a specific task manually assigned. The steering wheel housing pivots allowing the driver to configure the steering wheel angle for the ultimate comfort. Comfort can be further enhanced by the removable rubber back strap on the pistol grip. Two sizes of small and large are included in the radio package.
