The SkyAssistant variometer is a small on-board instrument which indicates the RC sailplane model's vertical speed by an audible signal. Lift is indicated by a pulsed tone with rate and frequency of the pulses depending on the climb rate. Sink is indicated by a low, continuous tone depending on the sink rate. Audible signal and voice messages about model state are transmitted by built-in radio transmitter and can be received on standard LPD or PMR receiver (European version), FRS (American version) or UHFUltra High Frequency (300-3000 MHz) CB (Australian version).
