Traxxas 6550 Telemetry Expander TQi

Telemetry expander for the TQi radio system.

The expander is what turns the TQi into a data system — it collects readings from temperature, voltage and RPM sensors and sends them back to the transmitter and the Traxxas Link app. On a nitro engine the temperature reading is the genuinely useful one: it tells you whether you are running lean before the engine tells you the expensive way.

Fits: Traxxas Jato 3.3 (55077-3) and other TQi-equipped models.

Sensors sold separately.
