A maker has designed an impressive DIY hovercraft that can glide over water, grass, and hard surfaces using a powerful air-cushion system. The body is made from four modular parts, 3D printed to fit standard printer sizes, with strong mounting points and precision bearings for smooth mechanical movement.
The hovercraft uses two motors, one for lift and one for forward thrust. A 5-inch three-blade propeller and a high-RPM brushless motor push it forward, while a separate motor fills the skirt with air to create the hover effect. Steering is handled by two metal-gear servos that direct airflow, giving it solid control on different surfaces.
The skirt is built from ripstop nylon, supported by foam and sealed tightly using silicone and O-Rings to keep the air pressure consistent. A camera module with wireless video streaming and LED navigation lights adds functionality and visibility. The electronics are neatly organized using terminal blocks and waterproof cable glands to handle vibrations and outdoor conditions.
The hovercraft is remote-controlled using a 2.4GHz antenna setup and designed with easy access to electronics, making it perfect for upgrades or repairs. Thanks to this mix of smart design and common materials, it serves well as an educational platform, a remote explorer, or just a fun DIY project to build and drive.
