Step-by-Step Instructions
1. Cut the hull shape from the lightweight plastic or foam sheet, approximately 30cm long and 20cm wide.
2. Attach the thin plastic sheet or balloon material underneath the hull edge to create a flexible skirt that can trap air for hovering. Secure it using double-sided tape or hot glue.
3. Mount the three drone motors with propellers at the front of the hull: one center and two slightly to the left and right but all facing straight up (0 degrees). Use hot glue or zip ties to secure them firmly.
4. Mount the single rear motor with propeller on the rear of the hull, facing sideways (90 degrees) for forward thrust.
5. Connect each motor to its respective ESC, and then connect all ESCs to the battery and microcontroller or ESC controller.
6. Program or configure the microcontroller to run the three front motors simultaneously for lift and the rear motor for thrust control.
7. Secure the battery and wiring on top of the hull using zip ties or tape, making sure the weight is balanced.
8. Perform a safety check: ensure all propellers spin freely without obstruction and wear safety goggles before testing.
9. Turn on the system in an open, smooth area. Slowly increase power to the front motors to create lift and hover. Then increase rear motor power to move forward.
10. Adjust power levels as needed for stable hovering and smooth forward movement.
