Tamiya 70213 Fin Kick Craft Set - Springing Arm Robot Kit  [70213]

Tamiya 70213 Fin Kick Craft Set: Hands-on STEM Model

The Tamiya 70213 Fin Kick Craft Set provides a practical way to learn basic mechanical concepts through building and testing. Part of Tamiya's STEM lineup, this kit balances educational value with approachable construction for hobbyists and younger builders.

Build Notes and Mechanism Overview

This kit uses a springing arm mechanism driven by two small motors to create a lively kicking motion that propels the robot forward. The compact footprint of 184mm long by 126mm wide and 82mm high keeps the build manageable, using a mix of snap-fit parts and screws to secure major components.

Operation and Performance Details

The model arrives with motors and switches already attached to simplify assembly. In trials the craft can travel roughly one metre in four to five seconds, demonstrating efficient gearing and motion. Rear bar stays add stability and help the unit right itself if it tips over, making runs more reliable.
