▲ Please drive on a flat surface, rough or loose sand and rock surfaces may damage the air cushion of the hovercraft. Do not drive on grass or rough sand or rough ground! .▲ Using high-speed motor and high-efficiency energy conversion device, the power is stronger and the speed is faster. .▲ The propulsion is stronger, and the flowing air is converted into kinetic energy more effectively, and the driving speed is greatly improved. .▲ 2. 4G high-frequency remote control system, long remote control distance, single frequency, suitable for multiple people to play at the same time without signal interference. .▲ When the water-sensing fan switch on the bottom of the boat is in contact with the water, it will automatically start the fan on the hull to generate a reaction force to make the boat float on the water, so that the hovercraft will not sink.
