Tamiya 70143 Universal Arm Set - Adjustable Beam Kit  [70143]

Tamiya 70143 Universal Arm Set for Robust Prototyping

The Tamiya 70143 Universal Arm Set is a practical collection of arms for makers and instructors focused on mechanical design. These pieces make it easy to experiment with linkages and structural layouts during prototyping sessions.

Engineered Hole Spacing

Each arm has a series of 3mm holes at 5mm intervals to ensure consistent spacing for joins and mounts. That regular grid speeds up assembly and pairs well with other Tamiya Construction elements.

Use Cases for Makers

Ideal for drive trains, articulated models, and proof-of-concept rigs, the arms are handy when testing geometry or adding modular extensions to a model. They support both static frames and moving mechanisms.

Reasons to Add This Set

• Flexible for a range of model and robotics tasks
• Matches the common Tamiya Construction hole system
• Useful for clubs, workshops, and solo projects
