FlySky GT2B is a 3-channel device perfect for car control. The simple service is an undoubted advantage for all those starting their adventure with remote controlled models. The set includes a GR3E receiver from the same manufacturer. The radio has been equipped with the Fail-Safe function, which protects the servos installed in the model from uncontrolled movements resulting from signal loss. In case of loss of communication, they will be stuck in their original position. The equipment also includes trimmers with reversal, ST (control trimmer), which allows centering of the front wheels or rudder and TH (throttle trimmer). The equipment also has a dual frequency, a function that allows you to reduce the sensitivity of the control and the maximum deflection of the servo (and therefore the turning radius). Power is provided by a 3.7V lithium-ion battery with a capacity of 800mAh, which eliminates the need to replace multiple batteries at the same time.
