mx-12 micro-computer transmitter with integral NiMH 8NH-1700 TX battery, R 700 receiver on the appropriate frequency, pair of crystals on the same frequency, C 577 servo, switch harness, battery holder for receiving system.

1. Basic system display: Normal display after switching the transmitter on, battery voltage / charge state, AIRPLANE / HELICOPTER model type, PPM / SPCM modulation, model memory No. 1-10, 8-letter model name, model operating time TOTAL T.
2. STICK MODE 1 - 4: Stick function layout. Selection of control function sequence (MODE 1 - 4), throttle left / right,to suit the pilot's preference.
3. LIST MODE set-up menu: In this menu model-specific and pilot-specific parameters are selected and adjusted, e.g.: Dual Rates, Travel Adjust, Servo Reverse, Sub-Trim, Mixer und Monitor program.
4. SWITCH SEL: Select menu for defining switches, position and assignment of switches for Dual Rates, Retracts, Mixer und Flap systems.
5. D/R + EXP: Dual Rate und Exponential set-up programs with separate adjustment facilities for Dual Rates and Exponential function for ailerons, elevator and rudder; Dual Rates 0 - 125%, EXPO -100% to +100%.
6. SUB-TRIM: Servo centre offset for six servos, ± 125 increments, for throttle, ailerons, elevator, rudder, retracts and collective pitch functions, model-specific, adjustable for each model separately, settings can be stored.
7. WING TYPE: Select menu: wing type. FLAPERON (two ailerons), ELEVON (delta system) and V-TAIL. The relevant mixer and servo functions are automatically assigned when you select the appropriate wing type.
8. DIFFERENTIAL ELEVON (Delta): Differential travel for model deltas with differential mixer, 0 - 100% (split mode), adjustable to suit the characteristics of the individual model.
9. TRAVEL ADJ: Travel adjustment, separately for left and right, 0 - 150%, for throttle, ailerons, elevator, rudder, retracts and collective pitch functions.
10. REVERSING SW: Servo reverse switches for throttle, ailerons, elevator, rudder, retract and flap servos, model-specific; can be selected and stored.
11. HELI basic system display: Screen displays transmitter battery voltage / charge state, HELI model type, model memory No. 1 - 10, 8-letter model name, PPM / SPCM modulation and model operating time TOTAL T.
12. MODEL SEL: Model Select menu: data for ten models can be stored separately, and called up when needed. The memories contain model type, PPM / SPCM modulation, model memory No. 1 - 10, model name and model operating time.
13. 120° CCPM: Set-up menu for fine adjustment of the swashplate system, required to compensate for system inaccuracies.
14. THRO CURVES: A five-point throttle curve system is available for fine-tuning the motor characteristics to the requirements of the individual helicopter.
15. MODULATION: Select modulation: PPM or SPCM, model memory-specific, to match the receiving system used in the model.
16. REVO MIX: Universal programmable mixers enable extreme special functions to be programmed, such as revolution mixing in helicopters.
17. PITCH CURVES: The optimum collective pitch setting for hovering can be obtained by setting up a five-point collective pitch curve system. Full-slow position, ¼ position, Centre position, ¾ position und Full-high position can be set independently.
18. MONIT servo travel monitor: The graphic servo travel monitor enables the user to check all servo functions simultaneously for servo centre and servo travels.
19. FAIL SAFE: In SPCM mode it is possible to program a PCM-Hold position for the servo functions. Fail-safe programming is not possible in PPM mode.
20. THROTTLE HOLD: The Throttle Hold menu enables you to set the auto-rotation throttle position very accurately.
21. MODEL COPY: The copy menu can be used to copy tested model configurations to different model memories to form the basis for a new model set-up.
22. SWASH TYPE: Swashplate type, 1 servo. Standard mechanical mixing. This type uses separate servos for the roll, pitch-axis and collective pitch functions.
23. SWASH TYPE: Swashplate type, 2 servos. Mixing with three roll / collective pitch servos; a mechanical mixer is used for the pitch-axis function.
24. SWASH TYPE: Swashplate type, 3 servos. Symmetrical three-point linkage, all three servos are used simultaneously for all three functions: roll, pitch-axis and collective pitch.
