The Graupner mc-20 is our most popular multi-purpose radio system on the market and for a good reason. It is jam-packed with features and functions at a competitive price! Its ergonomics provide easy-to-access control and switch layout, making it simple to set it to your personal preferences and needs. Adding or moving switches is done through a user-friendly interface and the navigation touch controls provide quick access all the software setup and programming menu options. The dual, high contrast LCD screens provide access to radio settings on the bottom screen while the top displays continuous telemetry information that can be activated with spoken voice alerts. Whether you fly handheld or tray with the mc-20 you can have both ways. The mc-20 can be configured for both styles depending on personal preferences.
The quad bearing 4096 resolution gimbals were machined with high-precision and are adjustable for smooth and 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.
VOICE and VISUAL TELEMETRY
Real-time telemetry is integrated in all our HoTT radio systems. The mc-20 does not require any additional hardware for functions such as signal quality, temperature, or receiver voltage. The included 12-channel and 6-channel receivers provide 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 mc-20 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! During flight, important data is logged on the SD memory card which can be analyzed to improve your system's reliability and performance.
Need to reverse your motor direction, setup your flight controller or program receiver settings? The mc-20 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 mc-20 radio to function as a browser to access the HoTT device and allowing you to make on-the-spot changes at the field and even in the air during flight!
The mc-20 in-flight control functions are adaptable to your personals. Each switch or control can be freely assigned to a channel or dedicated function. Or assign a logic switch, adding a new dimension of control to how you fly your model. You can set up a logical switch to combine two switches to change the state of function or channel. For example, will not allow your landing gear to come down unless you have your flaps in the landing position.
Additionally, moving or changing switch layouts is done easily from the back of the radio.
It is important to all of us at Graupner that you make good use of your investment in our products. All 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 mc-20, providing endless opportunities to discover all the radio has to offer.
Our Wireless Trainer Link allows the mc-20 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.
