The Temperature Sensor from Airtronics is compatible with the Airtronics 92010 (RX-461) receiver that is used with the Airtronics MT-4 2.4GHz FHSS-4T radio control system. The Temperature Sensor can be affixed to any number of different components on your models, such as your battery pack, electric motor or gas- or glow-powered engine's cylinder head to give you real-time temperature readings that are displayed on your MT-4 transmitter's Telemetry screen. This allows you to monitor and keep track of temperature readings while you're driving.
