The Mini Biplane wooden model has a turning propeller and is powered by a rubber band motor—just pull the model back along a surface to wind it up, then release and watch it go! No glue or special tools are required to assemble this DIY kit, just punch the pre-cut pieces out of their composite wood boards and snap them together. When assembling the airplane model, remember to lightly sand and wax the moving parts to make them run smoothly. The model's toy-like appearance and simple mechanics make the Mini Biplane an excellent starter model and introduction to the fascinating world of Ugears 3D puzzles, DIY model kits, automatons, robots, wooden puzzle boxes and STEM Lab model kits.
