Required Additional Components (Not Included in Kit):
The RD2.0 is an unassembled chassis kit. To operate the vehicle, you will need to purchase the following items separately:
Figure 4.1: Visual representation of essential components required to complete and operate the RC drift car.
- 2-Channel Transmitter & Receiver: For remote control of the vehicle.
- Steering Servo: To control the steering mechanism.
- Steering Gyro: Essential for drift control, assisting in maintaining slide angles.
- Speed Controller (ESC): To regulate motor speed and direction.
- Motor: The power unit for the vehicle.
- Battery: To power the motor and electronics.
- Charger: For recharging the battery.
- Drift Body: A complete body shell for the vehicle.
- Polycarbonate Paint: For customizing the drift body.
- Drift Tires & Wheels: Specific tires and wheels designed for drift performance.
Initial Adjustments:
- Steering Trim: Adjust the transmitter's steering trim so the wheels are straight when the steering wheel is centered.
- Throttle Trim: Ensure the throttle is neutral when the trigger is released.
- Suspension: Set initial ride height and damping according to the assembly manual's recommendations. Fine-tune later based on driving surface and preference.
- Gyro Sensitivity: Adjust the gyro sensitivity to provide stable drift control without overcorrection.
5. Operating
Once assembled and set up, your Yokomo Rookie Drift RD2.0 is ready for operation. Always operate your RC vehicle in a safe and responsible manner.
Basic Operation Guidelines:
- Power On Sequence: Always turn on your transmitter first, then the vehicle's receiver/ESC. When finished, turn off the vehicle first, then the transmitter.
- Steering: Use the steering wheel on your transmitter to control the direction of the front wheels.
- Throttle: Use the trigger on your transmitter to control forward and reverse movement, and speed.
- Drifting: Practice smooth throttle and steering inputs to initiate and maintain drifts. The steering gyro will assist in stabilizing the vehicle during slides.
Safety Precautions:
- Operate in open areas away from people, pets, and obstacles.
- Do not operate near public roads or in wet conditions.
- Always supervise children operating the vehicle.
- Ensure batteries are charged safely and correctly.
6. Maintenance
Regular maintenance will ensure the longevity and optimal performance of your Rookie Drift RD2.0.
Routine Checks:
- Inspect Screws: Periodically check all screws for tightness. Vibrations during operation can loosen them.
- Clean Moving Parts: Remove dirt and debris from suspension arms, steering linkages, and drivetrain components.
- Gear Inspection: The kit includes plastic gears in the drivetrain and differential. Inspect these regularly for wear or damage and replace as needed.
- Shock Absorbers: Check for leaks or inconsistent damping. Refill or replace shock oil as necessary.
- Tires: Inspect drift tires for wear. Replace them when performance degrades.
Lubrication:
Apply appropriate RC-specific grease or oil to moving metal-on-metal parts, such as universal joints and bearings, to reduce friction and wear.
7. Troubleshooting
This section addresses common issues you might encounter with your Rookie Drift RD2.0.
Common Issues and Solutions:
- Vehicle Not Responding:
- Check battery charge in both the vehicle and transmitter.
