4. Montage und Einrichtung

4.1 Chassis Layout and Rigidity

The TA08 PRO features a unique chassis layout that eliminates the need for an upper deck, balancing weight and rigidity. The battery pack and servo are positioned at a slight angle (approximately 10 degrees) to minimize surface contact during cornering and optimize weight distribution. This design contributes to appropriate pitching (longitudinal) and rolling (lateral) rigidity.

Abbildung 4.1: Seite view of the chassis layout. The design, without an upper deck, allows for tilting of battery and mechanical components to optimize the center of gravity, reducing overall height, width, and weight, while achieving balanced pitching and rolling rigidity.

4.2 V-Shaped Carbon Fiber Reinforced Resin Chassis

The chassis utilizes a V-shaped bottom and carbon fiber reinforced resin construction. This ensures high rigidity even without an upper deck. The balance of longitudinal (pitching) and lateral (rolling) rigidity has been optimized for performance. The front part of the rear suspension is designed to mount the suspension bushes directly to the chassis.

4.3 Optimized Weight Balance

Mounting the battery and R/C equipment in a V-shape optimizes the weight balance. This design contributes to a low overall height, width, and weight, enabling high driving performance on relatively low-grip surfaces, especially within Tamiya Challenge Cup regulations.

4.4 Slim Chassis and Bumper Design

The slim main chassis and distinctive bumper shape reduce interference with the road surface during rolling. The urethane bumper features strategically placed holes, and its shape is designed to facilitate airflow between the tires and bumper, further enhancing driving stability.

4.5 Spur Gear Placement

The spur gear is strategically positioned in front of the motor. This minimizes the difference in front and rear belt lengths, resulting in stable machine behavior. A shorter belt length also reduces resonance even with looser tension, thereby reducing drive loss.

4.6 New Suspension System

The new suspension system enhances rigidity and maximizes tire grip. It features A-type upper arms supported by ball joints. Compared to conventional upper arm suspension types, this design allows for easier load transfer to the tires, enabling solid tire grip even at Tamiya Challenge speeds and on relatively low-grip surfaces.

4.7 Rear Suspension with Toe Control

The rear suspension is equipped with a toe control function. The suspension mount is a hanging type, which increases rear rigidity and improves rear grip and driving stability. Both front and rear SSBB (Super Short Big Bore) dampers are utilized. The toe control function specifically enhances traction by allowing the suspension to sink during cornering.

4.8 Cable Storage Box

A compact cable storage box is included to neatly organize the wiring for the servo, speed controller, and receiver. Keeping the R/C equipment area tidy helps prevent accidental problems and ensures a clean setup.

5. Bedienungsanleitung

Once the chassis is fully assembled and all R/C equipment (motor, ESC, servo, receiver, battery, and transmitter) is installed and configured according to their respective manuals, you can begin operation. Ensure the battery is fully charged and the transmitter is properly bound to the receiver.

5.1 Vorlaufprüfungen

• Verify all screws are tightened and components are securely attached.
• Check steering and throttle response from the transmitter.
• Ensure wheels spin freely and suspension operates smoothly.
• Vergewissern Sie sich, dass der Akku vollständig geladen und sicher eingesetzt ist.

5.2 Fahrtipps

• Start with gentle throttle inputs to get a feel for the car's response.
• Practice steering in wide, open spaces before attempting tighter turns.
• Adjust camber and caster angles using turnbuckle shafts and lower arm spacers to fine-tune handling characteristics for different track conditions.
• Experiment with rotating body mounts (180 degrees) to switch between standard and 2mm advanced body positions, which allows for changing the car's balance with various bodies.

5.3 Relevante Videos

No official TAMIYA TA08 PRO assembly or operation videos were provided by the seller in the product data. Please refer to the detailed instruction manual included with your kit for step-by-step assembly and setup guides.

6. Wartung

Regular maintenance is crucial for the performance and longevity of your TA08 PRO chassis.

• After Each Run: Clean the chassis of dirt and debris. Inspect for any loose screws or damaged parts.
• Regelmäßig: Check the condition of the drive belts for wear or damage. Lubricate moving parts as recommended in the kit's detailed manual.
• Schock Dampers: Inspect SSBB shock dampers for leaks and ensure smooth operation. Refill with appropriate shock oil as needed.
• Lager: Clean and lubricate ball bearings regularly to ensure smooth rotation and reduce friction.
• Differenziale: Check the TRF420 oil-filled gear differentials for smooth operation and proper fluid levels.
