Wooden construction set "Single-propeller airplane", educational model

Educational STEM constructor - a wooden "Single Propeller Airplane" that can be assembled. The constructor helps children get acquainted with the basics of physics and engineering in the simplest way.
Features:
A constructor, toy and educational tool in one. The educational kit allows future engineers to assemble a working airplane that moves forward thanks to the airflow created by a propeller, while introducing the principles of aerodynamics and engineering.
During assembly, the child develops fine motor skills, accuracy, and engineering thinking.
The parts are made of child-safe materials. The sturdy construction is suitable for use and safe play. The model is also suitable for educational activities.
Young engineers can paint and decorate the toy with decorations to give it a unique style.
Easy assembly: simple and clear instructions allow children to assemble the toy with minimal adult supervision, making the set suitable for both independent work and activities with parents.
STEM (Science + Technology + Engineering + Mathematics) are educational methods that integrate science, technology, engineering, and mathematics into a coherent learning model to prepare the younger generation for a world of rapidly evolving technologies.
This is a great choice for a gift, as well as for schools and educational institutions where simple, reliable and clearly functioning educational models are needed.
Operating principle:
The engine, powered by batteries, quickly spins the propeller and creates an airflow that propels the plane forward.
Circuit Building: By connecting the battery holder and the motor, the child learns what a closed electrical circuit is. Electrical energy is converted into mechanical energy through a rotational motion that turns a propeller, which creates airflow. The direction of the electric current determines the direction of rotation (for the plane to move forward, the propeller must push air backward).
Reaction Force (Newton's Third Law): When the propeller pushes air backward, the air pushes the model forward with the same opposing force.
Engineering literacy: Develops the ability to read blueprints and connect components correctly so that the system works properly (e.g., not mixing up the polarity so that the propeller blows air forward instead of backward).
Rolling: Because the airplane is on freely rotating wheels, the force of air thrust is strong enough to overcome friction and cause the entire structure to roll along the surface.
Educational value: The model provides a practical introduction to the principles of physics and electrical engineering, energy conversion, movement, and the operation of electrical circuits.
Purpose: for home learning, classroom learning, project activities.
