Hand-held and tray-type transmitter:

With 8 control functions, the mc-16 HoTT lets the advanced RC model builder control nearly any model. The use of Graupner HoTT 2.4-GHz transmission technology ensures great functional reliability through bidirectional communication between transmitter and receiver, with integrated telemetry and ultra-fast response times.

The transmitter has 20 model memories. Programming by simplified programming with capacitive touch keys. A contrast-rich, 8-line, blue-lit graphic display ensures perfect display of all setting parameters and telemetry data. Telemetry data and additional model memories can be stored on a micro-SD memory card.

The channel signal is resolved at 12 bits in 4096 steps, thus providing extremely sensitive control.

USB connector for reading out and storing model memories and for firmware upgrades.

The processor in the CPU uses a sophisticated polynomial approximation method to calculate an ideal, correctly rounded MPC (multi-point curve) mixer curve.
• 7 flight phase programs can be adjusted individually for each model and assigned names; the switching time can be set separately.
• SUPER SERVO menu with a perfect overview of all servo setting data and simple correction of parameters for 4 levels (turning direction, centre position, bilaterally separate servo paths, and bilaterally separate travel limits for 8 servos with a total of 48 setting options)
• SUPER-DUAL-RATE, EXPO, and EXPO/DUAL-RATE menu with 36 possible setting variants, for 3 servo functions and 7 flight phases.
• Practical, optimised multi-function menus for fixed-wing and helicopter models. Entering the number of aileron and cambered flap servos automatically programs all the required mixer functions in the multifunction fixed-wing menu. Differential aileron mixer, butterfly mixer, dual-flap mixer, automatic gyro set function and additional special functions
• Helicopter swashplate mixer For 1, 2, 3, or 4-point linkage.
• Failsafe monitor for 8 servo functions
• Convenient timer menu. Stopwatch system, alarm timer, countdown timer, lap counter, et cetera. 2 times and 1 lap time can be displayed simultaneously.
• Stopwatch with history: In addition to the lap counter, there is a Time 1, which records the power-on times and a Time 2, which records the switched-on and switched-off times separately.
• Transmitter operating time timer is automatically set to zero by the transmitter battery charging process.
• Switch assignment of the flight phase switches: Now 6 switches, including 2 with priority function. The name of each switch combination can be selected freely. The number of flight phases thus does not depend on the number of flight phase switches.
• Linearization of swashplate servos: Electronic compensation for the nonlinear travel of swashplate rotary servos.
• Tailplane type normal, V-tail, Delta/flying wing. 2 elevator servos 3+8 (as a result 2 linkable elevator servos are immediately available without wasting free mixers/dual-mixers)
