Master your MG4 transmitter with this step-by-step setup tutorial! Learn to reverse steering/throttle channels (ST.REV/TH.REV), adjust steering/throttle endpoints (ST.D/R, TH.D/R) for maximum turn angle and throttle punch, and fine-tune neutral positions via trim knobs. The video demonstrates powering up the system: install batteries observing polarity, confirm ESC blue blink and receiver red LED, then bind transmitter. Key features include beginner mode activation (hold CH4 + rotate wheel counterclockwise) to limit throttle response for new drivers. Perfect for optimizing steering precision, throttle linearity, and adapting controls to racing conditions. Essential for competitive RC enthusiasts!
