Description

Airdrive Pro — DIY Air‑Engine Racer Kit

Age: 8+ | Pieces: 113
Assembled size: ~18.8 × 7.8 cm (L × H)

Build a battery‑free speed machine and race with the power of compressed air. The Airdrive Pro kit teaches basic engineering and pneumatics: assemble the air tank, piston, intake, exhaust, bumper and chassis, pump in air, release and feel the car rocket along—up to about 4 m/s with a range near 20 m. It even produces a realistic engine‑like sound for full pit‑crew drama.

What you get

• 113 buildable parts and a step‑by‑step manual
• Working air‑engine mechanism (no batteries or motors required)
• Eco‑friendly, hands‑on STEM experience for young builders

Performance & extras

• Top speed ≈ 4 m/s; practical range ≈ 20 m
• Requires simple household tools (crosshead screwdriver, diagonal cutters, small hammer) and optional water basin for testing

A fun, educational project that combines construction, physics and racing—ideal for budding engineers and weekend builders.
