Hosim Upgraded Front Gear-Box Assembly FY-QBX03

The Hosim front gear-box assembly is designed for 1/10 scale Hosim brushless models such as X07, X08, X07W, and X15W. It functions as a differential gear assembly (FY-QBX03) and is compatible with the FY-QBX02 upgraded part. The design centers on a helical gear system for smoother engagement, reduced noise, and minimized power loss. Built to withstand wear, the assembly emphasizes durability to extend both the gearbox and overall RC car life. This part is ideal for racers seeking consistent torque delivery and reduced maintenance over time.
4Set DC Electric TT Prewired Gear Motor Wheel Kit

This kit provides a complete TT motor wheel solution with 69mm plastic tires suitable for smart RC cars and robots. Operating from 3V to 12V DC (recommended 6–8V), it includes two 200mm wires and delivers a maximum torque around 800 gf·cm at 3V. The no-load speed is around 200 RPM at 4.5V, making it a practical upgrade for models needing reliable, prewired gearing and new tires. The kit serves as a versatile replacement for worn or damaged DC gear motors and supports straightforward installation in compatible chassis.
1/10 RC Car Transmission Case Gearbox (Titanium)

Constructed from high-quality aluminum alloy, this front-and-rear unit is designed for Axial SCX10 and similar 1/10 crawler configurations (not compatible with 90046). The titanium-grade housing and front aluminum protection cover provide robust support for demanding off-road runs. The internal alloy gears and precise machining offer smooth, quiet operation and excellent power transfer, helping crawlers maintain control over rocky or uneven terrain while reducing wear on drivetrain components over time.
1:16 Scale Brushless RC Car

This 1:16 scale brushless RC car emphasizes high-speed performance (reported at 50+ MPH) with a full-metal drivetrain and IPX4-rated waterproof chassis. It features adjustable hydraulic shocks for impact absorption and a reinforced chassis built to withstand drops from moderate heights. The pre-assembled model is well-suited for racers who want a capable, all-terrain RC car that can tackle mud, snow, and shallow water while maintaining structural integrity during aggressive driving and jumps.
INJORA Complete Gearbox Transmission

This complete gearbox set by INJORA includes all necessary gears with a durable nylon casing for smooth driving. It is designed for 1/10 crawler applications like Axial SCX10 and SCX10 II, providing reliable power transfer and straightforward assembly. The construction focuses on reducing flex and wear while maintaining quiet operation, making it a practical upgrade for enthusiasts looking to improve longevity and performance in their crawler builds.
Buying Guide
Key considerations when selecting a gearbox-equipped RC car or upgrade:
- Scale compatibility: Confirm the model and chassis family (1/10, 1/16, crawler vs. racer) to ensure the gearbox fits and aligns with drive axles and mounting points.
- Gear design: Helical vs. straight-cut gears impact noise, smoothness, and efficiency. Helical gears generally offer quieter and smoother operation but may require precise assembly.
- Material and durability: Aluminum or titanium gear housings reduce wear and provide rigidity, especially for high-torque vehicles or rugged terrain.
- Protection and adds-ons: Front or full aluminum protection covers help shield the drivetrain in impacts; consider sealed or IP-rated chassis if you run in wet or muddy conditions.
- Power compatibility: Ensure motor and ESC torque align with gearbox capability. Check voltage range and wiring to avoid overloading the gears.
- Maintenance: Look for gear lubrication options and serviceability. A modular gearbox simplifies replacements without dismantling the entire drivetrain.
- Upgrade path: Some gearboxes are designed as direct replacements; others may require adapter parts or additional intermediate components for compatibility with your model.
- Budget vs. performance: Higher-grade gears often deliver longer life and quieter operation but at a higher cost. Balance expected use with your investment.
When evaluating options, consider how the gearbox interacts with other drivetrain components like the motor, tires, and suspension. For crawlers, a robust alloy gearbox with protective covers often yields the best reliability on rugged courses. For racers, high-torque brushless systems paired with efficient gear trains can significantly boost acceleration and consistent top speeds across varied terrains. The five products above provide a spectrum of compatibility, materials, and performance targets to suit different RC goals.
