mc-16/20
Expandable Radio Control Set for a maximum of 16 channels
3
Using the proven computer system mc-16 as the basis of the new mc-16/20 Microcomputer Remote Control set was developed. With the series already equipped with 20 model memories, the mc-16/20 offers features to beginners and more experienced equally.
The controls and ergonomically optimised transmitter case have been developed further and gain an LCD for precise and clear display of all functions. It also enables, even in bright sunlight, secure adjusting and reading of all model-specific parameters.
A more intelligent chip and complex software offer a maximum of security and reliability. Owing to this innovative technology, modules for the implementation of complex coupled functions are no longer required in the transmitter, and complex mechanical mixers become unnecessary in the model construction.
The program selection, based on experience, are simpler and offer the scope and flexibility to adjust complex control functions to suit the requirements of the user. In particular, importance was attached to the interests of the intermediate user.
The user is persuaded by the simple and clear menu structure, and the conveniently fast selection of most functions. In addition, the mc-16/20 copes with every request up to the demanding competition application.
Half the program functions are common to the five different model types. Each type of model, from the simple glider to the modern high speed helicopter, contains model type specific functions, which allow programming of a flight model. Depending upon personal requirement and operator ability, individual functions can be switched off with optional external switches.
You should take notice of the organisation of the completely revised programming manual, and in particular to the clear and detailed operation and programming structure it represents.
Since the software covers special programs for the operation of both fixed-wing models and modern model helicopters, the operating instruction are arranged into several sections:
After a section concerning general operating instructions, the second section gives transmitter basic adjustments. Thus adjustments independent of model type, are described like model storage, name, type and modulation mode, among other things.
Following this are adjustments such as servo direction, servo reversal, freely programmable Mixers, etc., since these functions are common to all model types at your disposal. Afterwards the program descriptions for model types of the class of gliders and power planes follows.
STANDARD, UNIFLY, F3B / BUTTERFLY and AEROBATIC.
The fifth model type is dedicated to the helicopter. It covers all adjustment possibilities that available for the programming of a helicopter, even if they were already described for the fixed-wing models. This saves time consuming paging back and forward the instructions. Due to the complexity of the programs with this type of model it is recommended to observe the suggested programming order.
The reference sections are placed in front of the program sections for each type of model, and functions in clear flow charts and menu diagrams. Block diagrams clarify, in a simple way, the signal flow through the different functions that can be modified and between the control sticks and receiver outputs.
In the appendices the NAUTIC multi-function module is presented. It also contains information about further accessories, technical data etc.
Is advised that the beginner and less experienced model fliers initially attach as many servos as possible to the receiver and to first complete all functions in accordance with the guidance. He will learn, in the shortest possible time, the main operating steps of the mc-16/20 required to be able to make a meaningful program for the model to be finished.

Operating Instructions
6 General Section
Opening the Transmitter case
The removable back of the case is held by one locking catch and two interlock sliding catches.
Before opening the Transmitter ensure the power switch is OFF. The sliding catches are moved against the direction of arrow (inward) until they hit the stop, then case back can be opened. To close, insert the case back into the housing at the lower edge. Push it closed and then slide both caches in direction of the arrow (outward).
Changing the proportional control sticks and changing the centring force.
Both vertical control stick directions can be changed between centring or non-centring (e.g. throttle on the right or left). With the transmitter open and at the appropriate centring lever, notice the feather/spring (figure below. Lift up the centring lever to be able to get access, remove and keep the spring.
In the case of mechanical conversion of the throttle function, an electronic conversion of the control functions must also be made using the code "MOD" during the basic transmitter programming, see page
15. The ratchet strap provided in the accessories is mounted to the two captive nuts on the inside of the control stick units (photograph on the right).
The resistance to movement of the control stick can be adjusted between low to high by tightening or loosening of the adjusting screw.
The centring force of the control sticks can be adjusted at the screws indicated in the figure by an arrow:
Clockwise rotation – centring force higher Anti-clockwise rotation - centring force lower
General Section 7
Power Supply
The battery tray in the transmitter is equipped with a
9.6v battery.
Different battery types are available to be selected. Into the battery mounting for the receiver, insert four AA cells of 1.2v and between 500 and 600mAh. Instead of the battery mounting, or in addition, a 4.8v battery with miniature plug can be used, see page 5.
Pay attention to the full battery voltage. If the rudder moves noticeably more slowly or display the goes under 9.6v back then stop operation and load new batteries (or recharge).
Charger devices and batteries - see Graupner main catalogue telex.
Your contribution to environmental protection:
Do not throw to used up batteries into the domestic refuse, but take these to an appropriate collecting point, in order for them to be recycled or disposed of in an environmentally friendly way.
Charging of the Transmitter battery
The rechargeable transmitter battery can be charged in the Transmitter using the socket on the side of the case. The set must be switched OFF while charging.
When using the automatic MULTILADER 5B or 6E the connection is made by charging cable Part No.
3022. For the MULTILADER 5 it is necessary to use the polarised charging cable Part No. 3040.
The remote control system is equipped with a reverse connection protection circuit for charging of the Transmitter battery. Thus damage is prevented by incorrect polarity or short-circuit. In order to disable this reverse current protection (e.g. for measuring purposes or when connecting an automatic loader), it is necessary that the enclosed two-pole plug link is attached directly to the link pins as short circuiting bridge.
During rapid charging the transmitter battery charging current must not exceed 1.5A.
Charging the receiver battery.
The charging cable Part. No. 3021 for MULTILADERS 5B and MULTILADER 6E can used to connect the receiver battery directly to the charger. If the battery is in the model, then charging cables Part. No. 3023, 3046, 3377, 3934 or 3934,3 are attached making use of the connector integrated into the receiver switch harness. For the universal battery charger MULTILADER 5 the polarised charging cable Part. No. 3041 is necessary.
The period of operation of receiver batteries depends heavily on the battery type and on the frequency of servo movements and their load. In the PCM mode the "Fail Safe" function can be activated, which will display when the receiver battery falls below to a certain voltage, see page 25.
Operating Instructions
8 General Section
Frequency band and Channel change
Change frequency band
: The Transmitter can be operated on different frequency bands by changing the High Frequency module. The removable HF module is held by four sprung pin fittings in the centre of the Transmitter. Two cables must be attached. Link 1 connects to the Transmitter circuit board. Link 2 connects the HF module to the aerial.
Changes of the HF channels: The channel is determined by the crystal. Only crystals of the correct type and the appropriate frequency band may be used (see page 98).
The Transmitter crystals “T” is put into the HF module. Frequency band and channel number of the crystal inserted must correspond with that in the Receiver.
Installation the Module
The Transmitter case is pre-drilled for the installation of the modules, like NAUTIC, Proportional and Switch Module. The blanking caps in the holes of the case can be removed pushing them outward with an appropriate object. To complete the assembly of the Proportional and Switch modules, Part. No. 4152 or 4151, they must be connected to the HF module.
The NAUTIC modules are installed by inserting the controls through the pre-drilled holes in the case (from the inside) (see next paragraph "fastening the modules"). Ensure that the connection socket of these modules points to the centre of the transmitter.
General Section 9
Fasten the NAUTIC modules
Insert the module into the intended location and that check it fits correctly. The protective plastic film on the printed fascia plate can be now taken off. Then remove the backing paper of the double sided tape and the attach the fascia plate lightly pressing it down. Insert the module from the inside into the prepared module location. The module is secured by fitting the washers and nuts to the potentiometers or switches and carefully tightening them with a suitable tool. Finally, mount the control knobs to the potentiometers so they correspond with the scale markings.
Length adjustment of the control sticks
The length of the control sticks can be adjusted up to the maximum length marking on the stick shaft.
INC/DEC Keys
By installation of a 2 way momentary switch, Part. No. 4160.44, the functions of the INC / DEC keys can be taken over. The connection is made to the sockets marked INC and DEC on the transmitter circuit board, see page 10. The switch increases the operating ease, especially when model-specific values are programmed during operation.
Assembly of the Transmitter Carriers
The transmitter can be equipped with the transmitter mounting Part. No. 1127. Open the transmitter case and in remove the bottom blanking caps. The bottom of the case is already prepared for the assembly. The four mounting plate holes in the bottom of the case can be opened up by boring through using a screwdriver. From inside the case, insert the metal arms through the mounting holes. The plastic mounting plates are fed over the metal arms and screwed to the outside of the case, with two screws each. The carrier arms are strongly retained up a long coil spring. If softer folding of the carrier arms is required, the spring must be shortened accordingly.
