The remote control uses 2.4Ghz technology to achieve automatic frequency pairing

It can support multiple devices to play competitively at the same time. You must first pair the frequency separately before you can play together.
The remote control is about 50 meters away.

The boat is protected from water, and the boat has to be put into the water before it can be connected to the frequency.
