Nagaoka Shoten Elekit Aero Racer

The "Aero Racer" is a car that runs solely on air power, equipped with an air engine that operates using cylinders and pistons.
Because it uses compressed air energy as its power source, it does not require a motor or batteries.
A pump stores compressed air in an air tank, and when this air enters the cylinder, the piston of the air engine moves, generating the force to rotate the tire.
The air engine section is made of clear parts, allowing you to observe the piston in motion.
When the air engine starts, it makes a sound like a real engine and starts moving.
The estimated assembly time is approximately 2.5 hours.
