Master precision assembly of upgraded suspension arms and steering hubs for your RC car! Learn to install steering hubs with dual bearings (front/rear alignment critical), secure pivot balls with shims, and torque screws in sequence to avoid misalignment. For rear arms, optimize pivot points with dual bearings and dual shims per side for smooth suspension travel. Pro tips: Verify bearing orientation, follow step-by-step shim placement, and ensure rigid yet adjustable linkages. Elevate durability and handling for competitive racing!

Master differential maintenance for your RC car! This tutorial covers front differential disassembly: removing the second-floor plate, front arms, bumper, and suspension mounts to access gears. Rear differential steps include detaching the upper deck, drive shafts, and rear arms. Learn to inspect/swap worn gears and reassemble components in precise reverse order. Pro tips ensure correct drivetrain alignment for optimal performance.

Learn to diagnose and replace stripped spur gears on your RC car! This guide covers removing the 2nd-floor plate and upper deck, disassembling drivetrain components (drive cups, bearings, axle), and installing a new spur gear with precision alignment. Pro tip: Verify gear mesh and torque specs during reassembly to ensure smooth power delivery and prevent future damage. Essential for nitro and electric racers!

Master Body strut maintenance! This guide covers removing/installing front struts: unscrew bolts with a 2.0mm hex driver, align the dot-marked side inward, then re-tighten. Adjust strut height for terrain or handling preferences. Repeat for rear struts, ensuring directional alignment (dot-inwards) and secure mounting. Pro tips: Verify thread integrity, use threadlocker, and test suspension articulation post-rebuild. Perfect for optimizing stability and durability in competitive RC off-road racing!

Master dogbone replacement for your RC car’s front and rear suspension arms! Front dogbone steps: Remove wheels, extract hex hubs and pins, unbolt screws, align new dogbone with drive cup slots, and secure screws. Rear dogbone steps: Unmount screws, replace dogbone ensuring alignment with differential cups, and reassemble. Pro tips: Verify smooth rotation post-installation and avoid over-tightening screws. Essential for maintaining drivetrain reliability and off-road performance!

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!
