ble, it is essential to substitute longer aerials for the standard ones (approx. 145 mm long) fitted to HoTT receiver(s). The orientation of the aerial(s) is not critical, but it is advantageous to install one receiver aerial in a vertical – upright – position in the model. If your receiver is a Diversity type – two aerials – the active tip of the second aerial should be positioned at 90 ° to the tip of the first aerial, and ideally the distance between the two tips should be greater than 125 mm.
Safety notices Check the charge in batteries routinely, particularly the receiver’s battery. Do not wait until the movements of controlled mechanisms are noticeably slower. Replace expended batteries before they cause problems. The battery manufacturer’s charging instructions are always to be followed, this includes mandatory adherence to the length of charging time. Never leave batteries being charged unattended.

Safety notices and handling regulations for Lithium-Ion (LiIo) and Lithium-Polymer (LiPo) batteries As applicable for all highly technical products, observance of the following safety notices and handling instructions is essential for a long service life, fault-free operation, and harmless utilization of lithium/polymer batteries. These instructions are to be safeguarded. If the unit is transferred to another user, these instructions should certainly be passed along to the new user.
troduced. The temperature can easily be checked with the infrared thermometer, order no. 1963. The battery must never be discharged via the transmitter’s charging socket. This socket is not suitable for this purpose. Other handling notices • Never short-circuit the battery. A short-circuit allows very high current to flow and this heats up the cells. This will lead to loss of electrolyte, the production of gases and perhaps even explosions.
mc-16 and mc-20 The Newest Generation of Remote Control Technology The technical advances across the entire spectrum of model building is an ever-present challenge to design engineers. This is why the introduction of new transmission technology in the 2.4 GHz band represents a new milestone. The HoTT-System (Hopping Telemetry Transmission) developed by Graupner is a synthesis of know-how, engineering and testing done around the world by professional pilots.

Commissioning the transmitter Preliminary remarks about the mc-16 HoTT and mc-20 HoTT transmitters Preliminary remarks The Graupner/SJ HoTT system theoretically permits simultaneous operation of more than 200 models. However, because of the interspersed radio-frequency utilization permitted by certification for the 2.4 GHz ISM band, this number is significantly lower in practical application. Nevertheless, in general more models can be operated simultaneously in the 2.
• • GR-16 receiver supplied in the mc-16 HoTT set; this receiver is supplied already bound to the first model memory. Up to twelve servos can be operated with the GR-24 receiver supplied in the mc-20 HoTT set; this receiver is supplied already bound to the first model memory. In order to achieve the greatest possible flexibility but still preclude unnecessary inadvertent operator errors, control channels 5 … 8 respectively 5 … 12 have not been assigned to any controls.
Downloading a firmware packet Transmitter firmware updates are carried out … • … either as described under “FIRMWARE UPDATE / Change display language” in the section »Secret mode« on page 35 … • … or as described below with the help of a PC running a Windows XP, Vista or 7 operating system. Current software and information is available in Internet at www.graupner.de under the Download link for the given product.
Version “V4”. If you neglect this, individual components could malfunction. The same applies to future software packets, i. e. “V5” or higher. In contrast, if changes are made to individual firmware files within a particular version “VX”, then it is sufficient to install just the later firmware version for the corresponding product. The easy way to check whether firmware updates are available is to look at the creation date of the download file.
Transmitter firmware updates The USB interface cable (USB-A to mini-B-USB 5-pole) included with the set, will be needed to update the transmitter’s software via the transmitter’s faceside USB interface connector. This cable’s connector is to be directly plugged into the 5-pole mini-USB connector socket on the rear side of the transmitter. Important notes: • Please note that the HoTT components in your radio control system can only communicate perfectly if the firmware is compatible.
Switch off your receiver system if it is switched on then click on “Yes”. This will start the actual update process. A progress bar will begin to operate above a sequence of running text lines. The connection to the PC must not be interrupted during the update process! Click on “OK”. Subsequently switch off the transmitter and disconnect the USB cable between the transmitter and the PC or Laptop.
Restoring the transmitter software Program segment: “Restore” If a transmitter firmware update should fail, or if the transmitter software “hangs” – it may then be impossible to switch the transmitter off using the “POWER” switch – then you can reload the earlier firmware into the transmitter using the “Restore” program segment.

Receiver initialization Preliminary remarks Receiver system The mc-16 HoTT radio control set includes a GR16 bi-directional 2.4 GHz receiver, with sockets for a maximum of eight servos. The mc-20 HoTT set includes a GR-24 bi-directional 2.4 GHz receiver with sockets for a maximum of twelve servos.
out for just on three seconds, before only the red LED continues to flash. Release the button as soon as the LEDs go out. At the transmitter and receiver it is now possible to carry out a Binding procedure immediately. If the reset is done on a bound receiver and the corresponding model memory is active in the powered on transmitter, the LED will illuminate in green after 2 or 3 seconds as an indication that the transmitter/ receiver system is again ready for operation.
Receiver power supply Among other aspects, the safe operation of a model depends on a reliable power supply. In the event that, despite smooth operating rods, fully charged battery, battery leads with adequate cross-section, minimum contact resistances at connectors, etc.
Receiver system power supply NiMH 4-cell battery packs In compliance with the aforementioned conditions, your Graupner/SJ HoTT receiver system can be readily operated with traditional 4-cell battery packs as long as the packs have adequate capacity and voltage level. NiMH 5-cell battery packs Five-cell battery packs offer a greater voltage tolerance than do 4-cell packs.
Receiver firmware updates Receiver firmware updates for the GR-16 and GR-24 receivers, which are supplied as standard in the RC sets, are carried out using the side-mounted Telemetry socket marked “- + T” and a PC or laptop running Windows XP, Vista or 7. You will also require the USB leads supplied in the mc-16 HoTT and mc-20 HoTT sets, together with the USB interface, Order No. 7168.6, and the adapter lead, Order No. 7168.6S, both of which are also included.
Select the correct COM port in the “Port select” window, i. e. the port to which the USB interface is connected. This can be identified by the label “Silicon Labs CP210x USB to UART Bridge” in the “Device name” column. In the screen-shot shown above this would be the “COM 3” port. In the “Devices” folder, call up the “HoTT receiver” option under “Controller Menu”.
the Status display you will see “12, Complete !!” and at the same time the [Process Steps] display changes to “5”. When the update process is successfully concluded, the green LED on the receiver goes out, and the red LED starts flashing. If this process terminates before reaching the 100 % mark, switch off your receiver’s power supply then try to start the update process all over again. Do this by performing the above steps again.

As soon as the transfer is complete, the pop-up window “Receiver Data Write Success” appears: Repeat the procedure: Click on “OK” to conclude the data transfer procedure, then click on the “Disconnect” button to separate the Receiver Setup program from the receiver.
Installation notices Receiver installation Regardless of which Graupner receiver system you use, the procedure is always the same. Please pay attention that the receiver’s antennas must be mounted at least 5 cm away from all large metal parts or any wiring that is not directly routed out of the receiver itself. In addition to steel parts, this also includes carbon fiber parts, servos, fuel pumps and all kinds of cables etc.

Definitions of terms Control function, control, function input, control channel, mixer, kind of switches To make use of this manual easier, a number of the terms used repeatedly throughout this manual have been defined below. Control function A “control function” is to be perceived – initially independent of its signal path – as a signal intended to affect a given control function. For example, this could be for throttle, rudder or aileron in a winged aircraft or pitch, roll or crow for a helicopter.
before finally being applied as a control quantity for the respective servo. ing advantage of the programming examples beginning on page 280. Mixer The transmitter’s software contains a variety of mixer functions. These can be used to apply one control function to multiple servos or, conversely, to apply multiple control functions to a single servo. Please look over the numerous mixer functions in the text beginning on page 169 of this manual.
Physical control, switch and control switch assignments Principle procedure Maximum flexibility is offered by the mc-16 Hott and mc-20 HoTT system when it comes to assigning standard equipment operating elements to certain functions.
To this end, there are a total of 4 so-called “control switches”, C1 … C4, available whose switching direction can be established, even inverted, in the »Control switch« menu, page 145. • Logical switches, which are available as standard on the mc-20 transmitter only (but can be unlocked on the mc-16 HoTT at extra cost) allow two switches and / or control switches to be linked together logically in an “AND” or “OR” circuit. See the “Logical switches” menu on page 148.
Digital trim Functional description and description of C1 cut-off 70 Digital trim 1. Winged models C1 trimming has a special cut-off trim function intended especially for combustion motors. This cut-off trim function is configured as follows: First put the motor into a safe idle speed. Now if you push C1 trim in a single motion toward its „Motor cut-off“ direction until it is in its furthest travel position then an additional end-position marker will remain in the display.

What is a mixer? Basic functionality With many models, a mix of the model’s functions is often desirable, i. e. coupling aileron to rudder or coupling two servos together, in cases where rudder control surfaces with the same functionality are to be controlled together using a single servo. In all cases, the signal flow at the “output” of the control function on the transmitter control-side “branches” – , this also means: “downstream” of transmitter control options such as e. g.

The selected transmitter control directly controls the two flap servos located on receiver outputs 6 and 7 and, as required, also the two FL2 servos connected to outputs 9 and 10 – assuming that corresponding flaps have been specified on the “Aileron/camber flaps” line in the »Model type« menu.
the transmitter control does not influence any mixers on the “Brake settings” sub-menu. Otherwise, the mixer travel is expanded back to 100 % automatically. All other mixers in the »Wing mixers« menu have their neutral point with the control at its center, i. e. they have no effect at this control position. The value set is mixed in at full travel.

Optionally, this mixer can be activated and deactivated with one of the switches that is not self-restoring or a control switch so the model can be controlled with only the ailerons or rudder if desired. Typically, this mixer is set so that the rudder is deflec ted to the same side as the upward-oriented aileron, and you will find that setting a value of around 50 % is usually highly appropriate.

Range of transmitter control 7 Exemple: +50 % Gyro gain This means that at 0 % gyro suppression, gyro gain is constant for tail rotor stick movement; at 50 % suppression, gyro gain is reduced to half if the assigned transmitter control is moved to the +50 % position (as shown here); and only at >150 % suppression is gain reduced to zero with the slider at this position, well before full tail rotor deflection.

Helicopter mixer Auto-rotation setting Auto-rotation permits both full-size and model helicopters to land safely in a crisis, e. g. if the motor should fail. Moreover, if the tail rotor should fail, cutting the motor and landing using auto-rotation is also the only possible way to avoid a high-speed, uncontrollable rotation around the vertical axis and a resulting catastrophic crash – which is why a switchover TO the auto-rotation phase takes place immediately.
Tail rotor AR In normal flight, the tail rotor is set so that it compensates for motor torque while the model is hovering. It therefore generates some a certain amount of thrust even in its normal position. The level of thrust is then varied by the tail rotor control system, and also by the various mixers which provide all manner of torque compensation, while the tail rotor trim is also used to compensate for varying weather conditions, fluctuations in system rotational speed and other influences.
General notes on freely programmable mixers The previous pages have described a wealth of ready-to-use built-in coupling functions, in the context of the two menus »Wing mixers« and »Helicopter mixers«. The fundamental significance of mixers and the principle by which they work are described on page 169. The following section provides information about the so-called “free mixers”.

Tip: If you separate a control function – for example ,“9” – in the »Mix-only channel« menu, see page 216, then the servo’s response is determined exclusively by the mixer input of a mixer programmed from “9 9”. This menu is available as standard on the mc-20 HoTT transmitter only, but can be unlocked as an extra-cost option on the mc-16 HoTT.

Programming details The control curve is defined by up to 6 points, known as “reference points”. In the default software configuration, 2 reference points are already defined, namely only the two end-points, “L” and “H”; see the next screen image. The following section applies to “any” mixer to which we wish to assign a non-linear curve characteristic. The examples shown in the following section are merely illustrative, however, and they do not represent real-life mixer curves.

Trim point function Alternatively, with the Point value field active (i. e. highlighted) you can use the Select buttons of the left-hand four-way button to skip reference points L, 1 … max. 4 and H which you have already set, in the ascending or descending direction.

This is accomplished in the »Mixonly channel« menu, see page 216, which is available as standard on the mc-20 HoTT transmitter only, but can be unlocked on the mc16 HoTT transmitter at extra cost.

Teacher/pupil Connecting two transmitters for trainer mode with a trainer lead mc This option is available as standard on 16 20 both transmitter types. The transmitters mc-16 HoTT and mc-20 HoTT are equipped as standard – as viewed from the front, under the left front flap – with a DSC socket. This is not only usable for connecting flight simulators – as described on page 22 – but also to integrate the transmitter into a cable-coupled teacher/pupil system.
Note: The switch assignment just described also determines the transmitter used to issue the teacher and pupil functions, respectively. For this reason, a pupil transmitter must NEVER be assigned a switch on this menu. The header line therefore also switches from “Teacher / Pupil” to “Teacher / Teacher” once a switch has been assigned. The model to be controlled by the pupil must be programmed completely – i. e.
the teacher transmitter. Afterwards, assign the operating elements appropriately. Important: • If you should forget to assign a transmitter control on the pupil side, then the affected servo or servos will remain in the center position when the transfer is made to the pupil transmitter. • The pupil transmitter must always be operated in PPM mode, regardless of the RF connection type used between the teacher transmitter and the model.

Wireless HoTT system Wireless operation of the mc-16 HoTT and mc20 HoTT trainer mode system is also possible. To do so, the teacher transmitter must be “connected” to a pupil transmitter as described below. Prior to this, however, the training model’s receiver must be bound to the PUPIL transmitter. This configuration is possible between transmitters which have the “BIND:” option in the »Teacher/pupil« menu. Preparing for training mode Teacher transmitter The training model must be programmed completely, i.

During the … Training session … the teacher and pupil can maintain a variable distance from one another. But you should stay “within earshot” (max. 50 m) under any circumstances, however, no one else should be standing between the teacher and the pupil since these persons could reduce the connection range of the return channel used by the two transmitters.

entiation can be set: This serves to eliminate the negative torque. The downward deflected aileron normally generates a higher level of resistance during the flight than when deflected upward the same distance, whereby the model is pulled to the “wrong” side. In order to prevent this, with the input of a differentiation of the travel of the respective servo deflected downward is reduced accordingly. A value between 20 and 40 %, in this case, seldom arises, however, the “correct” setting must be sought.
the pilot and/or spectators at risk. Therefore, it would obviously be beneficial to program the function “Motor off” at the very least, in order to prevent such risks. With electro gliders, on the other hand, the fail-safe setting “motor off” can also be used, for example, for outlanding, to reliably stop the motor or its propeller by immediately switching off the transmitter after the landing. The author usually prefers a “braking finish” within eyeshot to floating off “somewhere else”.
Integration of an electric drive into the model programming In5 In6 In7 In8 GL GL GL GL fr fr fr fr ––– ––– ––– ––– typ SEL An electric drive can be controlled in different ways: The simplest method to integrate one such drive into the model programming is with the use of a throttle/ brake stick (C1).

merely “runs down”. toward the rear: Example 3 3-way switch usage This variant realizes a three-stage speed setting, such as Motor OFF, “half” and full power. A corresponding motor control (speed control) is required on the receiver side. The required settings are basically the same as those described under Example 1 and 2. Therefore, the same comments and recommendations also apply.
Control E-motor and crow alternately with C1 stick Example 4 Before we discuss the programming of this fourth example or turn to the expansion of the previously described basic programming, a few words should be said about the position of the throttle/brake stick with “Motor OFF” or “Brake OFF”. Normally the C1 control stick is moved forward for the throttle control and backward for the extension of the brake.
phase timer is automatically stopped and hidden in the base screen. More about this can be found on page 166. Now move the marker frame over the “ph.Tim” column to the “Motor” column to the right.
C1-stick switchable between E-motor and spoiler Example 5 If, contrary to the assumptions of the preceding Example 4, the model has additional spoilers or only spoilers, they can be incorporated into the control of the model by means of the following programming. Do this by programming the menus »Model type«, »Phase settings« and »Phase assignment« in the same manner as described under Example 4.
Timer confirmation with control or switch Examples 4 and 5 of the preceding pages If model programming is to be continued for Example 4, page 291, or Example 5, page 293, as described on previous pages or, completely independent of this example programming, the C1 stick (throttle/brake stick) is to be used for power regulation, then a control switch can be used to automatically start and stop the stopwatch.

C1 used in the example here should be “closed” in the “full throttle” direction and “open” below the switching point. Now switch to the menu … »Timers (general)« (page 162) … and select the line “Top” with the selection keys. This is the standard line assigned to the stopwatch.
Parallel operating servos A second servo running in parallel is often required, such as when brake flaps or spoilers installed in the wings or the left and right elevator or a double fin should be actuated by a servo or a large rudder flap should be simultaneously controlled by two servos due to high throw forces. In principle, this task could also be solved by connec ting the servos together on the model side using Ycable.

Two rudders We want to switch two rudders “in parallel”. The se cond rudder is located at the free receiver output 8.
Using flight phases Up to 7 different flight phases (flight conditions) can be programmed with settings independent of one another within each the model memory. Each of these flight phases can be called with a switch or a switch combination. This makes it possible to program different settings for various flight states, such as «Normal», «Thermal», «Speed», «Distance», etc., then make in-flight changeovers in a most convenient manner.
2nd Step In order to actually be able to switch between the individual flight phases, the assignment of one or multiple switches is necessary. Either one of the two threeway switches is ideally suited for switching between up to three flight phases. Each of the two switch end positions starting from the center position will be assigned to one of the flight phase switches A … F. The assignment of the switch takes place in the menu … »Phase assignment« (page 158) First select “C” with the marker frame.
4th Step Now three or four phases are programmed, the settings are also copied and there is even a “soft” transfer, but … there are still no flight-phase specific settings.

Turning away with the ailerons/landing flaps extended If you move the ailerons upward for the landing, the result is often a turning away over the longitudinal axis due to various servo paths of the aileron servos or due to design precisions. Therefore, the model begins to automatically hang the left or right wing.
Helicopter models With this programming example, you must have already covered the description of the individual menus and you must be familiar with the use of the transmitter. In addition, the helicopter’s mechanical construction should correspond exactly to the corresponding manual. The electronic capabilities of the transmitter should by no means be used to straighten out rough mechanical imprecision.

Enhancement recommendation: Rotational speed regulator At some point in time you may want to install a rotational speed regulator in the helicopter, in order to be able to fly with speeds automatically kept at a constant. In the process, it is logical to couple the individual rotational speeds with the flight phases so that further additional adjustments are possible.
