Description

With 12 control functions, the mx-20 HoTT lets the advanced RC model builder to control nearly any model. 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 24 model memories. Simplified programming using touch 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 connection for reading out and storing model memories and for firmware upgrades.

• Microcomputer remote control system with state-of-the-art 2.4 GHz Graupner HoTT technology
