Power and simplicity are the hallmarks of the mz-12 radio. Our best entry level radio that has earned many praises and even selected as radio of the year by a leading magazine. With its 6 channels and built in real-time voice telemetry you will experience a new level of connection between you and your model. Navigating through the basic and function menus is easy using the directional keys on the radio. A high contrast 128x64 LCD blue illuminated graphic display ensures clear presentation of radio settings and telemetry data.

The high precision quad bearings and adjustable gimbals provide a smooth feeling for accurate flight control. High reliability is achieved by hopping over 75 2.4 GHz channels to secure the most reliable interference free operating channel for a safe and worry free flight.


Telemetry is integrated in all of our HoTT (Hopping Telemetry Transmission) radio systems and the mz-12 will not require any additional purchase to benefit from important telemetry functions such as signal quality, temperature or receiver voltage. Like all of our HoTT receivers, the included 8ch receiver provides telemetry functions that can be configured to notify you in case of an imminent system failure. Graupner provides a wide selection of telemetry ESC's, modules and sensors that can connect directly to your HoTT receivers for immediate operation without the need for external hub boxes or complex wiring. Our third party partners provide additional telemetry products that will seamlessly work with your mz-24 HoTT radio.

Telemetry functions and notifications can be easily assigned to switches to provide information about battery voltage, used battery capacity, altitude, flight direction, speed and much more increasing your situational awareness and adding extra flight safety. No more surprises from sudden depleted batteries or flying out of range situations. The real-time bi-directional HoTT transmission protocol will constantly monitor system health and notify you when needed.


All HoTT products can be programmed and setup directly from the mz-12 radio. No need for cables, computers or programming boxes! Need to reverse your motor direction, setup your flight controller or make receiver settings? The mz-12 radio provides easy access to all the available functions of any HoTT device directly from the radio. Each HoTT device contains a user interface just like a website where your mz-12 radio functions as a browser to access the HoTT device allowing you to make on the spot changes at the field and even in the air during flight!


Making good use of your investment in Graupner products is important to us. All of our HoTT products such as receivers, flight stabilization systems, multirotor flight controllers, flybarless controllers, ESC s and many more are all designed to be compatible with another regardless of HoTT radio used. This unified technology standard will ensure the same operation and user experience across all devices increasing usability and ease of use when using Graupner HoTT products.

Our wide selection of HoTT flight controllers for flybarless helicopters, airplanes and multirotors will further enhance the usability of your mz-12 making it future proof for new developments.

Interoperability is further extended with our wireless trainer link where the mz-12 radio can be used with any other Graupner HoTT radio in student teacher mode.
