Tamiya 70266 WALKING BRACHIOSAURUS

Innovative Design and Transparent Mechanics

The Tamiya 70266 Walking Brachiosaurus kit boasts an innovative assembly approach for hobbyists and learners. It features a transparent plastic gearbox, which not only houses the built-in motor but also allows users to observe the inner mechanical workings as the model operates. This transparent design provides a unique educational opportunity, giving insight into the mechanics that drive the dinosaur's movement.

Large Scale and Enhanced Realism

Measuring approximately 432mm in length, 92mm in width, and 260mm in height, the Walking Brachiosaurus stands out as the largest model in Tamiya's Educational Construction dinosaur series. The model's lifelike gait is achieved through a sophisticated mechanical system, allowing the dinosaur to lope forward while swinging its head and tail side to side. These details, inspired by in-depth research conducted at the Fukui Prefectural Dinosaur Museum, help create a more realistic and captivating model for display and learning.

User-Friendly Assembly

This kit is designed with ease and safety in mind. The plastic gearbox comes pre-assembled, reducing the challenge of the build for beginners-only two cables need to be connected, making the process both straightforward and educational. The kit uses poplar wood parts, which are not only safe and easy to handle but can also be decorated and personalized with paints and pens, encouraging creativity.

Mechanical Performance and Operation

Powered by a single AA battery (sold separately), the Walking Brachiosaurus can operate continuously for about four hours. Its gear ratio of 288:1 results in a slow but steady walking speed of about 1.8cm per second, which translates to moving one meter in approximately 55 seconds. The innovative link and crank mechanisms enable realistic movement: forelegs are driven by the link mechanism, body movement shifts the weight to sway the head and tail, and the rotation controls the hind legs.

Accessibility and Challenge Level

Perfect for educational purposes, the model is recommended to be run on even surfaces to ensure smooth operation. It offers a moderate challenge, rated level 3 out of 5, making it accessible to both new and experienced builders. The expected assembly time is between 120 and 180 minutes, providing an engaging, hands-on experience that balances fun and learning.
