6. Setup Guide

6.1. Installing Electronics

1. Motor Installation: Securely mount your chosen brushless motor to the motor mount. Ensure proper gear mesh between the motor pinion and the spur gear. Refer to your motor's manual for specific mounting instructions.
2. ESC Installation: Mount the Electronic Speed Control (ESC) in the designated area, typically near the center of the chassis. Use double-sided tape or screws as appropriate. Connect the ESC to the motor and ensure all wiring is tidy and secured away from moving parts.
3. Steering Servo Installation: Install the steering servo into the servo mount. Connect the servo horn to the steering linkage. Ensure the servo operates freely without binding.
4. Receiver Installation: Mount the receiver in a protected location, typically in a receiver box to shield it from dirt and moisture. Connect the ESC, steering servo, and any other accessories to the appropriate channels on the receiver.
5. Battery Installation: Place your LiPo batteries into the dual XL battery trays. Secure them firmly using the provided straps to prevent movement during operation. Ensure the battery connectors match the ESC's connectors (IC5 or EC5 recommended).

6.2. Body Preparation and Mounting

The vehicle comes with a factory-finished body. You may need to trim the rear wing for optimal performance or adjust its angle. Use sharp hobby scissors for precise cuts.
