The 2.4G communication, PA module (for signal amplification) and FHSS
(Frequency-Hopping Spread Spectrum implemented by the remote
guarantee signals’ stability and users’ safety.

The small remote, which implemented the 2.4G bi-directional
communication, is specially designed to pair the FOC ESC. It
features a series of functions like forward/backward direction switch,
gear switch, remote battery level indication, and skateboard battery
level indication. Two warning modes: LED flashing & vibration remind
users of possible issue(s). And the hand-held design makes the
interactive mode clear and simple.
