Power and simplicity are the hallmarks of the mz-12 radio. This is our best entry-level radio and has earned many praises -- it was even selected as Radio of the Year by a leading magazine! Experience a new level of connection between you and your model with 6 channels and built-in real-time voice telemetry. Easily navigate through menus and setup options using the radio's directional keys. A high-contrast 128x64 blue LCD illuminated graphic display provides a clear presentation of radio settings and telemetry data.

The high precision quad bearings and adjustable gimbals provide a smooth feeling for accurate flight control. Safe and worry-free flights are achieved with our HoTT (Hopping Telemetry Transmission) technology by hopping over 75 2.4 GHz channels to secure the most reliable, interference-free operating channel.  


Telemetry is integrated in all our HoTT (Hopping Telemetry Transmission) radio systems.   The mz-12 comes with all the necessary hardware and software for important telemetry functions such as signal quality, temperature, or receiver voltage. The included 6-channel receiver provides telemetry functions that can be configured to notify you regarding any system changes. Graupner provides a wide selection of telemetry ESCs, modules and sensors that can immediately connect directly to your HoTT receivers without the need for external hub boxes or complex wiring. Our third-party partners provide additional telemetry products that work seamlessly with your mz-12 HoTT radio.

Telemetry functions and notifications can be easily assigned to switches to provide information about battery voltage, battery capacity, altitude, flight direction, speed, etc.  This is integral in increasing your situational awareness and adding extra flight safety. The real-time, bi-directional HoTT transmission protocol will constantly monitor system health and notify you of any changes to the system.  No more surprise situations such as sudden battery depletion or accidentally flying out-of-range!


Need to reverse your motor direction, setup your flight controller or program receiver settings? The mz-12 radio can easily setup, program, and change all Graupner HoTT products remotely. No need for cables, computers or programming boxes!   Each HoTT device contains a website-like user interface allowing 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!


It is important to all of us at Graupner that you make good use of your investment in our products.  All of our HoTT products (receivers, flight stabilization systems, ESCs, multirotor flight controllers, flybarless controllers, etc.) are designed to be compatible with one another regardless of the transmitter being used. This unified technology standard will ensure the same operation and user experience across all devices, making our products future-proof for new developments.

Our wide selection of HoTT flight controllers for flybarless helicopters, airplanes and multirotors will further enhance the usability of your mz-12, providing endless opportunities to discover all the radio has to offer.

Our Wireless Trainer Link allows the mz-12 radio to be used with any other Graupner HoTT radio in Student/Teacher Mode, allowing everyone to learn or teach about the wondrous experiences this hobby has to offer.
