5. Initial Setup
Before your first drive, follow these steps to prepare your BlackZon Smyter MT Turbo.
5.1. Charging the Vehicle Battery
- Connect the included battery charger to a suitable power outlet.
- Connect the Li-Po 7.4V 1600mAh battery to the charger. Ensure the T-Plug connection is secure.
- Observe the charger's indicator lights (refer to charger manual if provided) to confirm charging status.
- Once charging is complete (indicator light changes or turns off), disconnect the battery from the charger.
- Important: Never leave charging batteries unattended. Do not overcharge.
5.2. Installing Transmitter Batteries
- Locate the battery compartment on the bottom of the transmitter.
- Slide open the battery compartment cover.
- Insert 3 AA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Close the battery compartment cover securely.
5.3. Installing Vehicle Battery
- Remove the body clips and carefully lift the truck body off the chassis.
- Locate the battery compartment on the chassis.
- Place the charged Li-Po battery into the compartment.
- Connect the battery's T-Plug to the corresponding T-Plug connector on the ESC/Receiver unit. Ensure a firm connection.
- Secure the battery in place using any straps or clips provided.
- Re-attach the truck body, securing it with the body clips.
5.4. Binding the Transmitter and Receiver
Your truck and transmitter should be pre-bound from the factory. If they lose connection or you are using a new transmitter/receiver, follow these steps to re-bind:
- Ensure both the transmitter and vehicle are turned OFF.
- Turn ON the transmitter.
- Turn ON the vehicle's power switch (on the ESC/Receiver unit).
- The LED on the ESC/Receiver unit should indicate a successful connection (e.g., solid green light). If it blinks, refer to the ESC/Receiver manual for specific binding instructions, which usually involves pressing a bind button on the receiver while powering on.
- Test steering and throttle response to confirm successful binding.
6. Operating Instructions
Once setup is complete, you are ready to operate your BlackZon Smyter MT Turbo.
6.1. Starting the Vehicle
- Place the vehicle on a flat, clear surface.
- Turn ON the transmitter first.
- Turn ON the vehicle's power switch. The ESC/Receiver LED should illuminate, indicating it's ready.
6.2. Driving Controls
- Forward: Pull the throttle trigger towards the grip.
- Brake: Push the throttle trigger away from the grip (from neutral position).
- Reverse: After braking, push the throttle trigger away from the grip again to engage reverse.
- Steering: Rotate the steering wheel clockwise to turn right, counter-clockwise to turn left.
6.3. Adjusting Trim and Dual Rate
- Steering Trim: If the vehicle does not drive straight when the steering wheel is centered, adjust the Steering Trim dial on the transmitter until it tracks straight.
- Throttle Trim: If the vehicle moves slightly forward or backward when the throttle trigger is at neutral, adjust the Throttle Trim dial until it remains stationary.
- Dual Rate (D/R): This dial controls the maximum steering angle. Turn it down for less sensitive steering (good for high speeds or beginners) and up for more sensitive steering (for tighter turns).
6.4. Ending Operation
- Turn OFF the vehicle's power switch first.
- Turn OFF the transmitter.
- Disconnect the battery from the vehicle and remove it for storage or charging.
- Allow the motor and ESC to cool down before handling or storing.
7. Maintenance
Regular maintenance will extend the lifespan and performance of your BlackZon Smyter MT Turbo.
- Cleaning: After each use, especially in dusty or dirty conditions, clean the vehicle. Use a soft brush or compressed air to remove dirt and debris from the chassis, suspension, and drivetrain. Avoid using water directly on electronics.
- Inspection: Regularly inspect for loose screws, damaged parts (e.g., bent suspension arms, cracked chassis, worn tires), and proper functioning of all moving parts.
- Drivetrain: Check the steel spur gear and differential gears for wear. Ensure metal driveshafts and hex hubs are secure.
- Shocks: Check oil-filled shocks for leaks and proper damping. Refill or replace shock oil as needed.
- Bearings: The vehicle features a complete set of ball bearings. Periodically check them for smooth operation and clean/lubricate if necessary.
- Battery Storage: Store Li-Po batteries at a "storage charge" level (typically 3.8V per cell) if not used for extended periods.
- Lubrication: Apply appropriate RC-specific lubricant to moving metal parts as needed, avoiding electronics.
