Ensure peak performance with proper motor pinion maintenance! This video covers inspecting pinion engagement: confirm the pinion grips the spur gear tightly to avoid slippage. For installation, align the pinion’s flat side with the motor shaft, apply threadlocker to grub screws, and tighten securely. Adjust gear mesh using the A4 paper trick: insert a strip between gears, press pinion into the spur, tighten screws, then remove the paper for perfect clearance. Prevent power loss and gear wear with these pro techniques!

Master shock tuning and maintenance! Adjustment: Press the spring downward and rotate the shock collar to fine-tune preload for optimal handling. Installation: Secure long screws with a 2.5mm hex driver and short screws with a 2.0mm hex driver, ensuring correct orientation. Removal: Reverse the process using matching tools. Perfect for racers dialing in suspension performance on rough terrain!

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!
