Safety notes Please read carefully! We all want you to have many hours of pleasure in our mutual hobby of modelling, and safety is an important aspect of this. It is absolutely essential that you read right through these instructions and take careful note of all our safety recommendations. If you are a beginner to the world of radio-controlled model aircraft, boats and cars, we strongly advise that you seek out an experienced modeller in your field and ask him for help and advice.
Safety notes Installing the servos Always install servos using the vibration-damping grommets supplied. The rubber grommets provide some degree of protection from mechanical shocks and severe vibration. Installing control linkages The basic rule is that all linkages should be installed in such a way that the pushrods move accurately, smoothly and freely.
Safety notes Disconnect all batteries and remove them from your model if you know you will not be using it in the near future. In very difficult cases a second filter can be used, positioned close to the servo. Capacity and operating times This rule applies to all forms of electrical power source: battery capacity is reduced every time you charge it. At low temperatures capacity is greatly reduced, i.e. operating times are shorter in cold conditions.
Computer system mx-12 6 channel digital proportional radio control system Computer radio control system with 10 model memories, incorporating high-level technology. Modern computer system for excellent reliability and security. Simplified rotary programming technology for straightforward programming.
• MODULATION: switchable PPM / SPCM • DUAL RATE / EXPO switchable to two positions and programmable for three servo functions, available range 5 to 125%. • DIFFERENTIAL FLAPERON (differential aileron mixer) • SUB-trim memory system for offsetting all servo centres; also for adjusting older servo types and servos with no standard centre • TRAVEL ADJUST: separate travel adjustment for both end-points of all servos adjustment range 0 to 150%.
Charging the transmitter battery Charging the transmitter battery The rechargeable transmitter battery can be charged via the charge socket fitted to the side of the case. The transmitter must be switched „OFF“ for the whole period of the charge process. Never switch on the transmitter when it is still connected to the charger; even a very brief interruption in the charge process can cause the charge voltage to rise to the point where the transmitter is immediately damaged by the excess voltage.

System Mode Model Selection; Model Name Entry Model Selection The mx-12 system offers memory for ten completely separate models. Therefore, it is possible to have a mixture of helicopter and airplane setups retained in memory. It is also recommended that the Model Name Entry function be used in conjunction with each model setup. Another very useful function of the Model Selection function is the ability to set one aircraft up several different ways. This is helpful when multi-task performance is desired.

System Mode Trainer Function Trainer Function The mx-12 offers a programmable trainer function with three trainer options: Normal mode: - In this mode the transmitter acts as a conventional buddy-box system. The transmitter can be used as a slave or as a master: however in this mode, the reversing switches and trims must be adjusted so the slave transmitter matches the master transmitter. In normal mode, when the trainer switch is activated, the student has control of all functions and switches.
System Mode Switch Select Switch Select The mx-12 allows the several options to be programmed for the dual rate, gear and flap switches (flight mode switches for heli). Aileron and Elevator dual rates can be programmed to be individually selected via its own switch (individ) or the aileron, elevator and rudder functions can be combined to operate from one of four switches.
System Mode Wing Type Selection ELEV D/R The gear channel operates from the elevator dual rate switch. INHIBIT The gear channel is inhibited and is centered making it useful as a slave channel for mixing. RIGHT SW The gear channel operates from the right upper (flap) switch. Flight Mode LEFT SW (default) The flight mode operates from the left upper (gear) switch. AILE D/R The flight mode operates from the aileron dual rate switch ELEV D/R The flight mode operates from the elevator dual rate switch.
System Mode direction. Note: Each servo‘s travel direction is adjusted individually through the Servo Reversing function. Once the servos achieve their proper travel direction, adjust their travel amount, dual rates, sub-trim and aileron differential. Note: The applicable channel‘s left or right travel adjustment may be made individually by accessing the Travel Adjust function. Refer to the Travel Adjust section of this manual for more information.
System Mode V-Tail Type Selection V-tail mixing is available as an option with your mx-12. V-tail equipped aircraft require two servos. Connect left servo to the aileron port of the receiver Connect right servo to the elevator port of the receiver Accessing and Utilizing the V-Tail Type Selection 1. While the Down and Select keys are pressed, move the power switch to the ON position to access the System mode. 2. Press either the Up or Down key until WING TYPE appears on the LCD. 3.
