The 6 channel mz-12 RTF Multirotor HoTT is a 2.4GHz voice telemetry radio designed to work with almost any type of multirotor setup. The integrated GR-18 receiver and flight controller eliminates the complexity of setting up your multirotor - just install the GR-18, select your multirotor configuration, attach and calibrate your ESC's and go fly!


Out-of-the-box the mz-12 and GR-18 flight controller is programmed to work with any type of 250-300 size race copter. In case you need to make setting changes no computer or programming boxes are needed. The mz-12 radio provides convenient wireless access to many advanced settings available on the GR-18 flight controller to you with optimizing your setup in a minimal amount of time.  Changes can be made anytime at the field or even during flight!


The Graupner hopping telemetry protocol (HoTT) provides continuous bi-directional communication between the mz-12 radio and GR-18 sending real-time information of telemetry and system health status for a safe operation of your multirotor. Thanks to an optimized frequency hopping algorithm across 75 frequency channels, operating your multirotor is reliable due to immunity of external interference.


Real-time telemetry is king with any Graupner HoTT radio. The mz-12 radio and GR-18 flight controller are constantly communicating with another exchanging critical flight information such as receiver voltage, signal strength and temperatures. To increase flight safety and situational awareness, the built-in voice processor will notify you about specific programmable telemetry events. 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 radio.


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 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 exciting experiences this hobby has to offer.
