General Use

LG55 is a rugged tethering station for multi-rotor drones. This compact and robust solution enables the transmission of power from an external ground  power supply unit to the drone through the micro-tether. The core of the    micro-tether ensures the drone remains attached to the base station

providing a safe phase of flight.
