Futaba 4EX_c4 High Precision 4-Channel Car Transmitter  [4EX_c4]

Track-Pro Control with Futaba 4EX_c4

The Futaba 4EX_c4 is a compact 4-channel FM transmitter built to give RC car drivers refined control and steady performance. It includes exponential settings for ailerons, elevator, and rudder plus wing mixing for V-tail and elevon setups to help deliver predictable steering and throttle response on the track.

Key Electronics and Setup

The unit features a 40-segment LCD for clear status readout and adjustment. Servo reversing and analog trims with memory make setup quicker, while End Point Adjustment (EPA) on all four channels lets you limit travel precisely to match your servos and linkages.

Power Options and System Compatibility

The transmitter uses FM modulation and accepts either a 9.6V NT8S600B NiCd pack or a 12V alkaline battery. A built-in low battery alarm helps avoid mid-session shutdowns, and the trainer system plus trainer box support make it useful for skill development and paired practice.
