AIR KONTROLER SPIDER BT - VARIO
The device is designed for easy monitoring of motors working in danger of temporary thermal shock that might affect on motor propulsion.
The controller indicates fuel level in the tank, informs about Moto-hours amount and shows air humidity that affects propulsion efficiency and wing load ability in flying devices.
