Tamiya 70270 Walking & Swimming Duck STEM Classroom Kit  [70270]

What the Tamiya 70270 Walking & Swimming Duck shows

This non-scale STEM Robocraft model demonstrates both walking movements and simple water propulsion when assembled. The Tamiya 70270 is intended as an educational mechanicaI model rather than a performance Mini 4WD chassis.

As part of Tamiya's STEM/Robocraft lineup, the kit is aimed at hobbyists and learners curious about motion mechanisms. The construction features basic sealed elements for limited water interaction and straightforward linkages; it is not designed for racing conversions or prolonged heavy load use.

Assembly tips and routine care

• Assemble with common plastic modelling tools, taking care at pivot points; adhere to the manual for lubrication and clearance instructions.
• Dry any parts that touched water after use and inspect moving areas for grit or corrosion before storing.
• Source replacement pieces from official Tamiya spares to keep the model functioning as intended.
• Use the model as a demonstration of motion and buoyancy rather than a continuous duty vehicle, since small internal components are not made for extended heavy loads.

A compact and instructive build, the Walking & Swimming Duck suits educational setups, hands-on study, and collectors who enjoy mechanical novelty rather than race-ready Mini 4WD kits.
