If you’re considering an upgrade or looking for a high-performance chassis that delivers precision, speed, and versatility, this comprehensive review will cover everything you need to know about the TA07 RR—from its features and design to its performance and real-world usability.

Introduction to the Tamiya TA07 RR

The Tamiya TA07 RR is a 1/10 scale electric touring car chassis designed for those who want to push the limits of performance. As an evolution of the TA07 Pro and TA07 R, this “RR” version integrates a range of high-end upgrades, making it even more competitive in club racing and high-level competitions.

With a single-belt drivetrain, advanced suspension components, and Tamiya Racing Factory (TRF) parts, the TA07 RR is engineered for precision, agility, and maximum speed. Let’s break down its features and see what makes this chassis special.

Key Features of the Tamiya TA07 RR

1. Single Belt Drive System

• The single belt drive is one of the defining characteristics of the TA07 series. Unlike traditional dual-belt systems, this layout minimizes mechanical complexity, reducing friction and energy loss, which translates to smoother power delivery.
• The belt runs along a central spine, offering improved balance and three possible motor positions, allowing racers to optimize the weight distribution for different track conditions.

2. High-Quality TRF Components

• TRF419 suspension arms and TRF super short big bore dampers offer improved handling and adjustability.
• The low-friction drivetrain with lightweight pulleys ensures efficiency and durability.

3. Carbon Fiber Reinforced Chassis

• The main chassis and upper deck are constructed from high-quality carbon fiber, giving it a stiff yet lightweight frame for maximum responsiveness and durability.
• The reinforced motor mount ensures better cooling and reduces unwanted flex.

4. Adjustable Suspension System

• The adjustable suspension geometry allows for fine-tuning of camber, toe-in, and ride height to suit different track surfaces.
• It includes stabilizers and adjustable shock positions to help dial in the perfect setup.

5. Low-Friction Drive Train

• The aluminum bulkheads and low-friction ball differentials contribute to a smooth and efficient power transfer.
• The lightweight drive pulleys reduce rotational mass, allowing for quicker acceleration.

6. Multiple Motor Positions

• One of the standout features is the ability to adjust the motor position in three different locations (rearward, center, and forward), giving racers the flexibility to alter the weight distribution for varying track conditions.

Design and Build Quality

Chassis Layout & Structure

The TA07 RR features a narrow chassis design, reducing ground contact and improving aerodynamics. The low center of gravity ensures excellent cornering stability, making it an ideal choice for high-speed racing.

Material Quality

• Carbon fiber reinforced plastic is used extensively for the main chassis and upper deck, providing the perfect blend of rigidity and flexibility.
• Aluminum front and rear bulkheads contribute to a strong, lightweight, and heat-resistant structure.

Ease of Assembly

• The TA07 RR is a kit, meaning it requires assembly. However, Tamiya provides detailed, step-by-step instructions, making it accessible even to those who are relatively new to advanced RC builds.
• The screw-together assembly (rather than glue-based construction) makes future modifications and upgrades easier.

Performance on the Track

Acceleration and Speed

• Thanks to its lightweight construction and efficient belt drive, the TA07 RR accelerates rapidly, giving it an edge in drag races and quick sprints.
• The drivetrain and precision TRF components ensure minimal power loss, meaning faster straight-line speeds and immediate throttle response.

Cornering and Handling

• The TA07 RR shines in cornering stability. The low center of gravity, combined with the super short big bore dampers, provides exceptional traction and balance when navigating tight turns.
• The adjustable suspension system allows drivers to tweak the handling to match track conditions, whether it’s a high-grip asphalt surface or a more technical indoor carpet track.

Braking and Stability

• The carbon fiber chassis and balanced weight distribution ensure the TA07 RR remains stable under braking, preventing front-end dive and maintaining control during aggressive deceleration.
• The low-friction drivetrain prevents abrupt weight shifts, allowing for smoother braking and acceleration transitions.

Assembly and Maintenance

Ease of Assembly

• Tamiya kits are known for their precision and clarity in instructions. The TA07 RR follows this tradition with a detailed, illustrated manual that makes the building process intuitive.
• Pre-cut and precision-molded parts ensure a frustration-free assembly experience.

Maintenance & Upkeep

• Quick access to key components makes maintenance relatively simple, even for beginners.
• The single belt system means fewer parts to manage compared to double-belt chassis, reducing overall wear and tear.
• The suspension system and drive components are modular, meaning easy repairs and upgrades.
