Graupner MX-12 HoTT Transmitter

With 6 control functions, the mx-12 HoTT lets the advanced RC model builder to control numerous models. The use of Graupner HoTT 2.4-GHz transmission technology ensures great functional reliability through bidirectional communication between transmitter and receiver, with integrated telemetry, voice output via headphone output, and ultrafast response times.
The transmitter has 10 model memories. Programming by keys. A contrast-rich, 8-line, blue-lit graphic display ensures perfect display of all setting parameters and telemetry data. Telemetry data and additional model memories can be stored on a micro-SD memory card. (later after update)
The channel signal is resolved at 12 bits in 4096 steps, thus providing extremely sensitive control.
USB connector for reading out and storing model memories and for firmware upgrades.
Voice output via headphone output is available as an option.
