Tamiya 70270 non-scale walking-and-swimming drivetrain STEM Robocraft model kit Walking & Swimming Duck  [70270]

Tamiya 70270 Walking & Swimming Duck - STEM Robocraft model

It is a non-scale STEM Robocraft walking and swimming animal kit in Tamiya's STEM Series, positioned as an educational Robocraft model rather than a racing Mini 4WD. The product name indicates the intended motion modes: walking on land and basic propulsion in water when assembled and powered.

This item is cataloged under Tamiya's STEM/Robocraft line and is aimed at model builders interested in mechanical motion and educational assembly. The build focuses on basic mechanical linkages and sealed sections suitable for limited water interaction; it is not a competitive Mini 4WD chassis and is not intended for racing upgrades.

Build and maintenance notes

• Assembly requires standard model-building tools and attention to moving joints; follow the supplied instructions for lubrication points and tolerances.
• After any water operation, components that contact water should be dried to reduce corrosion or dirt buildup; inspect moving parts for wear before reuse.
• Replacement parts and service items should be sourced from official Tamiya spares when available to retain original fit and function.
• Keep the model as a mechanical demonstration of walking and buoyant motion rather than as a performance vehicle; internal mechanisms may include small drive components that are not rated for continuous high-load operation.

The Walking & Swimming Duck is a compact STEM Robocraft model that presents simple terrestrial and aquatic motion. It is suited for educational displays, hands-on mechanical study, and collectors who value mechanical novelty rather than competitive Mini 4WD performance.
