Sanwa/Airtronics MT-4 2.4GHz surface radio, the FHSS-4T telemetry version with the Multi Function Full Dots display. Powers on and boots to the model screen, shown in the photos. Comes with the matching RX-461 telemetry receiver, which is MT-4-specific and often hard to find on its own.

Cosmetically it's a used radio with normal handling wear. The steering wheel foam is worn and could be refreshed, priced accordingly. Everything else is clean and the buttons, trims, and dial are all present.

Included: MT-4 transmitter, RX-461 receiver, battery cover 

Sold as-is from a working setup. Great as a spare transmitter, or the practical way to run any RX-461 or other FHSS-4T receivers you already own.
