When these talented bicycle mechanics set out to build their first heavier-than-air powered aircraft, they needed wings that were lightweight and strong. They opted for a biplane design, reminiscent of the early gliders. Biplanes have two fixed wings, one stacked above the other, connected by several struts. The aerodynamics allow for a lighter wing structure.

Ugears is known for creating beautiful wooden DIY designs, characterized by a particular sensitivity. The Ugears Mini Biplane model is both a fun toy and an attractive decorative item for display on a shelf. We chose an open design, making the Mini-Biplane light and transparent, revealing the internal workings of the model.

The wooden Mini-Biplane model features a rotating propeller and is powered by a rubber band motor - simply pull the model back along a surface to wind it up, then release it and watch it go! No glue or special tools are needed to assemble this DIY kit; just push the pre-cut pieces out of their wooden boards and fit them together.

When assembling the airplane model, remember to lightly sand and wax the moving parts for smooth operation. The playful appearance of the model and its simple mechanics make the Mini Biplane an excellent starter model and an introduction to the exciting world of Ugears' 3D puzzles, automata, and robots. As your child learns to build these enchanting and exciting mechanical puzzles, they will also develop their mechanical skills.
