Setup and Assembly
This section outlines the general steps for assembling the Himoto EXB-16 chassis and installing necessary electronic components. Refer to detailed diagrams for specific part identification.
- Chassis Assembly: Securely attach the front and rear suspension arms, shock towers, and bulkheads to the main chassis plate using the provided screws. Ensure all pivot points move freely without excessive play.
- Differential and Drive Train Installation: Install the front and rear differentials into their respective bulkheads. Connect the center drive shaft between the front and rear gearboxes. Ensure smooth rotation of all gears.
- Shock Absorber Installation: Fill the shock absorbers with appropriate shock oil (not included) and install them onto the shock towers and suspension arms. Adjust spring preload as desired.
- Steering System: Assemble the steering linkages and connect them to the front knuckles. Install the steering servo (not included) onto the chassis and connect it to the steering bellcrank.
- Motor and ESC Installation: Mount your chosen brushless or brushed motor (not included) to the motor mount. Install the pinion gear (provided or purchased separately) onto the motor shaft and adjust the gear mesh with the spur gear. Secure the Electronic Speed Controller (ESC, not included) to the chassis.
- Receiver and Battery Tray: Install the RC receiver (not included) in a waterproof receiver box if available. Secure the battery tray and strap for your chosen battery pack (not included).
- Wheel and Tire Mounting: Attach the wheels and tires to the wheel hexes. Ensure wheel nuts are tightened securely but not overtightened.
- Body Mounting: Secure the body posts and attach the body shell (not included) using body clips.

Operating Guidelines
Once fully assembled with electronics, follow these general guidelines for operating your Himoto EXB-16 buggy.
- Pre-Run Check: Before each use, inspect all screws, nuts, and linkages for tightness. Check tire condition and ensure the battery is fully charged.
- Initial Power-Up: Turn on the transmitter first, then the vehicle's ESC. Reverse this order when powering down.
- Driving Environment: Operate the buggy in open, clear areas. Avoid water, deep mud, or extremely dusty conditions unless the electronics are specifically rated for such environments.
- Control: Practice smooth throttle and steering inputs. Avoid sudden, aggressive maneuvers that can damage components.
- Battery Management: Do not over-discharge your battery. Stop operation when you notice a significant drop in performance.

Maintenance
Regular maintenance is crucial for the longevity and performance of your Himoto EXB-16 buggy.
- Post-Run Cleaning: After each use, especially in dirty conditions, clean the chassis with a soft brush or compressed air. Remove any debris from moving parts.
- Inspection: Regularly inspect for worn or damaged parts, including tires, suspension components, gears, and drive shafts. Replace damaged parts promptly.
- Lubrication: Apply appropriate grease or oil to moving metal-on-metal parts, such as universal joints and differential gears, as needed. Avoid over-lubrication.
- Shock Absorbers: Check shock oil levels and replace if necessary. Inspect O-rings for leaks.
- Fasteners: Periodically check and tighten all screws and nuts. Use thread-locking compound on metal-to-metal screws where appropriate (e.g., motor mount screws).
