The variometer is a telemetry sensor for sailplanes that indicates the rate of ascent and descent via an audible tone using select Spektrum™ transmitters*. This provides an indicator to the pilot when the sailplane is in a thermal of rising , or sinking air. By knowing when the sailplane is rising or sinking, the pilot can keep the sailplane in rising air and out of sinking air providing longer flight times.
Know when your sailplane is in a thermal and fly longer durations with the Spektrum variometer.
