The 16 channel mc-32 PRO is absolutely packed with features, functions and user-friendly interfaces making this the best trey radio for pilots in need for optimal reliability and precision control.  It is equipped with our unique HoTT telemetry technology that uses up to 75 frequency-hopping channels to ensure extreme operating reliability and immunity to external interference.  The mc-32 PRO is beautifully designed with an aluminum frame and black highlighting and comes with two LCD screens for maximum efficiency.  Monitoring telemetry data and transmitter data from two independent screens has never been so easy.


The bi-directional data transmission provides you with real-time telemetry, such as receiver voltage, battery voltage, battery usage, signal quality, temperature, etc. to help you 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!  By using brushless control + T ESC, or HoTT sensor modules (sold separately), you can check additional real-time data such as RPM, receiver voltage, current, motor temperature, and enable voice notifications to sound through the speaker.


The mc-32 PRO includes many other features, grouped into a new user-friendly menu system.  Future-proof your radio by upgrading with the free Graupner Update Studio, or populate up to 80 model memory slots internally and on the Micro SD card.  Program the swashplate limiter to prevent striking mechanical parts during simultaneous full roll and pitch-axis maneuvers in 3D helicopter operations.  Precisely calibrate digital trim through the aluminum scroll wheels, or use the auto-trim function.  Simply and easily assign control elements, such as stick, external switch, proportional control, and trim lever as control functions.  The 8-stopwatch system, alarm timer, countdown timer, lap counter, etc., allows for 2 timers and 1 lap time to be displayed simultaneously and in large characters. 


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.  We are certain that the mc-32 PRO radio will provide you with the best possible experiences this hobby has to offer.
