Using this hovercraft kit is easy. First, gather the required items like the whoop frame, motors, and batteries. Then, start assembling the parts from the kit. Attach the 3D - printed motor mounts to the foam body parts. Next, add the bottom skid pad. Make sure to install the flight controller properly and connect it to the motors. When choosing batteries, pick one between 200mAh and 600mAh. Remember, a programmable flight controller gives you more control. For maintenance, keep the foam parts clean and check the motor mounts regularly for any signs of wear. Avoid exposing the hovercraft to water or rough surfaces. If you have any issues, refer to Drone Junkie's build video for troubleshooting.
