Tamiya Twin Motor Gearbox

The Tamiya Twin Motor Gearbox is a compact, high-performance mechanical kit designed for robotics and educational builds. It features two FA-130 brushed DC motors, each driving a separate 3mm hexagonal output shaft, allowing for independent control and complex motion.

Builders can choose between two gear ratios:

• 58:1 for high-speed applications
• 203:1 for increased torque and slower movement

This gearbox is perfect for small-scale robots, tank-style chassis, and custom mechanical projects. Its reinforced plastic gears and casing ensure smooth operation and long-lasting durability. No cement is required for assembly, making it beginner-friendly and ideal for classroom use.

The kit supports STEM learning by teaching gear mechanics, torque, and motion control. It’s compatible with Tamiya’s track and wheel sets, universal plates, and 2-channel remote controllers, offering endless possibilities for creative engineering.

Kit Includes:

• Two FA-130 motors
• Gearbox casing and gears
• Hexagonal output shafts
• Assembly instructions
• Gear ratio options: 58:1 and 203:1
