Required Tools
- Phillips head screwdrivers (various sizes)
- Hobby knife or side cutters for plastic parts
- Needle-nose pliers
- Hex wrenches (if using optional aluminum parts)
- Shock oil and grease (included)
Pre-Assembly Checks
Before starting assembly, ensure all parts are present and free from defects. Familiarize yourself with the different plastic trees (A, B, C, etc.) and their corresponding parts. The chassis tub features specific mounting points for the SRX steering assembly, differing from standard TT-02 variants.

Operating Your TT-02 Type-SRX
First Run
Once assembled, ensure your battery is fully charged and properly secured. Connect your ESC, motor, and steering servo according to their respective manuals. Perform a range check with your radio system before driving. Start in an open area free from obstacles.
Driving Tips
- Begin with gentle throttle inputs to get a feel for the car's response.
- Practice smooth steering inputs to maintain control, especially in corners.
- The oil-filled differential and direct spool provide stable handling; experiment with different driving lines.
- Adjust suspension settings (camber, toe, ride height) to fine-tune performance on different surfaces.
Maintenance
Regular maintenance is crucial for the longevity and performance of your TT-02 Type-SRX chassis.
Regular Checks
- Inspect all screws and nuts for tightness after each run.
- Check for any loose or damaged parts, especially in the suspension and drivetrain.
- Ensure the ball bearings are clean and spin freely.
Cleaning
Remove dirt and debris from the chassis using a soft brush or compressed air. Pay attention to the gears and moving parts to prevent wear.
Lubrication
Apply appropriate grease to moving parts as specified in the manual. Regularly check and replenish the oil in the rear differential unit.
The oil-filled differential gear unit requires periodic maintenance.
