This propeller joint is an essential component when upgrading your TT-01 or TT-02 drivetrain. For best results, use these joints in combination with the aluminum driveshaft for a complete, slop-free drivetrain. The improvement in precision is most noticeable with powerful motors.
Compatibility
These joints are designed for TT-02 chassis but may work with TT-01 in some applications. Check your specific chassis and driveshaft configuration before purchasing. The joints work best when used with matching Tamiya brand components.
TT-01 Hop-Up Buying Guide
Upgrading a TT-01 can be overwhelming with so many options available. Based on years of experience with the platform, I recommend following a logical upgrade sequence that maximizes performance gains while minimizing wasted money.
The Essential Three
Start with ball bearings, an aluminum prop shaft, and oil shocks. These three upgrades provide the biggest performance improvement per dollar spent. The bearings reduce friction, the prop shaft prevents power loss, and the oil shocks transform handling. These upgrades benefit any TT-01 regardless of other modifications.
Motor Upgrade Path
After the essentials, focus on the motor mount and heatsink before upgrading the motor itself. A solid motor mount ensures your investment in a better motor pays off. For motors, start with a Torque-Tuned or Sport Tuned motor for predictable power. Only move to Super Stock or brushless systems after you have developed sufficient driving skill to control the extra speed.
Compatibility Across TT-01 Variants
TT-01, TT-01 Type-E, and TT-01R share many common parts but have important differences. The Type-E features refined suspension geometry and accepts some TT-02 upgrades. Always verify compatibility before purchasing parts for your specific chassis. Some TT-02 parts like bearings and driveshafts work across platforms, but others are chassis-specific.
Brushless Conversion Considerations
The TT-01 can handle brushless power with proper preparation. Essential upgrades for brushless include the aluminum prop shaft, metal motor mount, ball bearings, oil shocks, and CVA universal drive shafts. Without these upgrades, brushless power will quickly destroy stock components. Even with proper upgrades, recognize that the TT-01 was not designed for brushless power and may require more frequent maintenance.
Frequently Asked Questions
What are the essential upgrades for TT-01?
The community consensus on essential TT-01 upgrades consists of three key parts: ball bearings to reduce drivetrain friction, an aluminum prop shaft to prevent power loss, and oil-filled shocks to improve handling. These three upgrades provide the most significant performance gains and should be your first purchases. After these, focus on motor mount and motor upgrades based on your performance goals.
Is the TT-01 worth upgrading?
The TT-01 is worth upgrading for beginners and intermediate drivers who want to learn car setup and driving skills without investing in expensive racing platforms. The upgrade path teaches valuable lessons about RC mechanics and tuning. However, experienced racers may eventually outgrow the platform and benefit more from moving to a purpose-built racing chassis like the TT-02 or TB-04 rather than heavily modifying a TT-01.
What motor should I put in my TT-01?
For first upgrades, the Torque-Tuned or Sport Tuned motors provide excellent power gains while remaining compatible with stock electronics. Intermediate drivers should consider the Super Stock RZ or TZ motors for maximum brushed performance. Brushless conversions are possible but require additional upgrades including aluminum prop shaft, metal motor mount, ball bearings, oil shocks, and universal drive shafts to handle the extra power.
Should I get oil shocks for TT-01?
Oil shocks are highly recommended for any TT-01 beyond basic bashing. The difference in handling and stability compared to stock friction shocks is dramatic. Oil shocks allow you to tune suspension for different track conditions and driving styles. The improvement in cornering speed and bump handling makes this upgrade worthwhile for both racing and spirited bashing.
Can you put brushless in TT-01?
Yes, the TT-01 can handle brushless power with proper preparation. Essential upgrades for brushless conversion include aluminum prop shaft, metal motor mount, ball bearings, oil-filled shocks, and CVA universal drive shafts. These upgrades prevent the stock plastic components from failing under brushless torque. Even with upgrades, recognize that the TT-01 was designed for brushed power and may require more maintenance when running brushless systems.
Final Thoughts on TT-01 Hop-Up Parts
The TT-01 remains one of the most upgrade-friendly platforms in the RC world, with a vast selection of hop-up parts available. By focusing on the essential upgrades first and building systematically, you can transform a basic TT-01 into a capable performer that teaches valuable lessons about RC setup and tuning.
Remember that the best Tamiya TT-01 hop-up parts are those that match your driving skill and intended use. Start with bearings, prop shaft, and oil shocks for immediate improvements across all areas of performance. Add motor upgrades gradually as your skills improve, and consider moving to a more advanced chassis when you have outgrown the TT-01’s potential.
Happy upgrading, and may your TT-01 be faster and more predictable in 2026 than ever before.
