Servo installation Always mount servos with the provided rubber vibration-damper parts. Only in this manner can these parts be protected against excessively hard vibrations. Installing control rods Control rods must be installed such that they operate freely and smoothly. It is particularly important that all rudder levers are able to move to their full limits, i.e. not otherwise mechanically blocked.
Safety notices Capacity and operating time The rule: "capacity is reduced with every successive recharging", applies to all batteries. Internal resistance increases at low temperatures to further reduce capacity. As a consequence, the battery's ability to provide current and hold its voltage is reduced. Frequent charging or the use of battery maintenance programs can also result in gradual loss of battery capacity.

Commissioning the transmitter Preliminary remarks about the mc-20 HoTT transmitter Preliminary remarks The Graupner HoTT system theoretically permits simultaneous operation of more than 200 models. However, because of the interspersed radiofrequency 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.
Transmitter firmware updates • • • Universal/EUROPE mode be used IN FRANCE. As many as 16 servos can be attached to the standard receiver included with the mc-20 HoTT 2.4 Set. The specific receiver included in the set has already been bound to the set's transmitter at the factory. In order to achieve the greatest possible flexibility but still preclude unnecessary inadvertent operator errors, control channels 5 … 16 have not been assigned to any controls.
Now use your Internet browser's vertical scroll bar to move down the page a bit until the tabs "Characteristics", "Spare parts" "Accessories" and "Downloads" appear. Because the "Downloads" tab is still missing on the mc-20 HoTT transmitter's page at the time of this manual's printing: Store the file on your computer in a directory of your choice.

be the "COM 3" port. Now call up menu option "Firmware Upgrade" from "Menu" or open the "Controller Menu" and click on "Firmware Upgrade". This will start the actual update process. A progress bar will begin to operate above a sequence of running text lines. Click on the button labeled "File Browse" and select the desired firmware update file with a ".bin" filename extension from the "Open file" window. Firmware files are product-specifically coded, i.e.
Receiver initialization Preliminary remarks about the GR-32 DUAL receiver Receiver system The mc-20 HoTT remote control set includes a type GR-32 DUAL, 2.4 GHz bidirectional receiver for connecting up to 16 servos. After switching on this HoTT receiver, should "its" transmitter not be within range or switched off, then the receiver's red LED will illuminate continuously for about 1 s then begin to blink slowly. This indicates the receiver has not (yet) established a link to a Graupner HoTT transmitter.
Receiver power supply 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., the transmitter indicates repeated receiver voltage collapses or is receiver voltage is generally too low; please give attention to the following notices.
Receiver system power supply NiMH 4-cell battery packs In compliance with the aforementioned conditions, your Graupner 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.
General charging notices • The charging instructions for the charger as well as for the battery from its manufacturer to be observed. • Pay attention to the maximum permissible charging current specified by the battery's manufacturer. In order to prevent damage to the transmitter, charging current should never exceed 1 A. If necessary, limit the current at the charger.
Receiver firmware updates Receiver firmware updates are made by way of the connector located on the side of the receiver and the help of a PC running under Windows XP, Vista or Windows 7. The optional USB interface cable needed for this is order no.7168.6 along with adapter cable, order no.7168.6A. The programs and files also needed can be found in Internet on the Graupner website at www.graupner.de under the downloads for the particular product. Note: After registering your receiver at https://www.graupner.
not correspond to the product (e.g. a transmitter update file instead of a receiver update file), the "Product code error" popup window will appear and the update process will not start. Activate the control labeled "Program". Wait for the progress bar to start. Depending on the speed of the computer being used, this may take several seconds. Now switch on the receiver while holding its SET button down. After a few seconds the "Found target device …" message will appear in the status display.
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.

Term definitions Control function, control, function input, control channel, mixer, switch, control switch, fixed switch To make use of this mc-20 HoTT 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.
this programming child's play. Learn about this by taking advantage of the programming examples beginning on page 268. Logical switches These functions permit two switches, control switches and/or logical switches or any combination of these to be combined with one another to create logical "AND" and "OR" functionality. A total of 8 logical switches, "L1 … L8" can be programmed, see page 138. Fixed switches FXI and FX This type of switch turns a function, e.g.
Physical control, switch and control switch assignments Principle procedure Maximum flexibility is offered by the mc-20 Hott system when it comes to assigning standard equipment operating elements to certain functions.
• The two FX switches switch a function on "FXI" or off "FX " permanently. • All other switches mentioned can have multiple assignments. Pay attention that you do not UNINTENTIONALLY assign reciprocally conflicting functions to a single switch. If necessary, note down the given switch functions. Typical applications: • Shut-off of an on-board glow plug heater upon underrun or overrun of an idle threshold point programmed for the C1 joystick.
Digital trimming Functional description and description of C1 cut-off Digital trim with visible and audible indicators Both joysticks are equipped for digital trimming. By default, turning trim wheels will offset the joystick's neutral position by 4 increments (out of a possible 100 steps per side). This offset is also reported acoustically. A brief press on the trim wheel will reset an existing trim offset back to "0". Any other "zero points" can be specified with the help of the »Trim memory« menu.

Perform a range test on the Graupner HoTT system according to the following instructions. If necessary, have someone assist you in carrying out the range test. 1. Preferably, the receiver already bound to the transmitter should be installed into the model in its intended position. 2.
When this technique is evaluated during competitions, the motor must be switched off for autorotation. On the other hand, for training mode it is advantageous to keep the motor at idle for autorotation. The Autorotation switch causes a switchover to the autorotation flight phase in which control of "throttle" and "pitch" are separate and all mixers which have an effect on the throttle servo are switched off.
A speed controller or throttle servo will only take on this preset position when a certain servo position or threshold is underrun and a switch is activated. This is done by setting the desired servo position (threshold value) into the middle column field, directly over the column label STO, then selecting the appropriate ON/OFF switch function in the right column. • If the percentage value specified for the middle column is greater than the current servo position, i.e.

Notes: • Be sure that during the switch assignment, the joysticks for aileron, elevator and rudder are in their neutral positions as otherwise their offsets from neutral will be adopted right away in trim memory as the trim value. • Since EVERY activation of the Auto trim switch has a cumulative effect, after concluding an "auto trim" flight, the assigned auto trim switch should be deactivated for reasons of safety.

Channel 1 CURVE Note: In contrast, when the throttle limiter is closed, the position of the throttle/collective pitch stick is meaningless. It can therefore remain at the maximum collective pitch position so that, when adjusting carburetor linkages, the throttle limiter alone can be used to switch between full throttle (throttle limiter open) and "Motor OFF" (throttle limiter closed). Now, with the throttle limiter closed, adjust the carburetor linkages so that the carburetor is (just) completely closed.
Throttle limit in combination with "Thr AR" in the »Stick mode« menu Time delay for the throttle limiter To safely prevent the carburetor from opening too rapidly, assign the throttle limiter input "Tl16" to a time delay that takes effect only in the direction of full throttle. This applies especially if the throttle limiter is controlled by a switch rather than, as preset, with the right-side proportional rotary slider.

How is a flight phase programmed? The concept of flight phase programming General information on flight phase programming During a flight, you will often want to apply different settings – e.g. flap or trim settings for a fixed-wing aircraft or collective pitch and throttle servo settings for a helicopter – at particular times in the flight (e.g. take-off, approach, hover, auto-rotate, etc.). With mc20 HoTT, you can access such presets automatically using switches or control switches.

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.

termed "adverse yaw". This effect is naturally greater on the comparably long aerofoils possessed by model gliders, compared to e.g. powered aircraft models, which generally have relatively short moment arms. For the former, it must normally be compensated for by making a simultaneous rudder deflection in the opposite direction.

El ¼ Fl (elevator ¼ flap) To provide support for the elevator for tight turns and aerobatics, this mixer can be used to make the flap function follow controls sent to the elevator.
Note: The Offset, i.e. the activation direction, is also set in the »Model type« menu, pager 94. This offset should be set to about +90 % of stick travel (if the C1 joystick is used, this is generally located at the forward position of the stick). To extend the flaps, the stick must therefore be moved back towards the pilot. The remaining joystick travel of around 10 % then has no effect, although it is not "lost", since the control travel is automatically expanded back to 100 %.

The value to be set depends both on the speed controller used and on the target motor speed that is desired, and can, of course, be varied according to the flight phase. For auto-rotation flight, an automatic switch-over is made from this mixer to a configurable default value; see page 190.

Fine-tuning the throttle and collective pitch curve Practical approach Note: The hover point should normally be set to the center position of the throttle / collective pitch stick. In special cases, e.g. for "3D" flight, deviating hover points can also be programmed.

Helicopter mixers 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.
function. 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 159. The following section provides information about the so-called "free mixers".

Thus, with linear mixers LinearMIX 1 … 8 or curve mixers CurveMIX 9 … 12, 8-point control curves can be defined for any transmitter control in a manner analogous to that described in the »Channel 1 curve« menu and these can also be used in flight phase switching if needed. This method of "linking" is not only also switchable but can even be subject to a delay by assigning an appropriate delay in the "– time +" column of the »Control adjust« menu.

Programming details The control curve is defined by up to 8 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.

Teacher/pupil Connecting two transmitters for trainer mode with a trainer lead The mc-20 HoTT transmitter is equipped 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.

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 / Teach" once a switch has been assigned. The model to be controlled by the pupil must be programmed completely – i.e.
dual axis sticks (1 … 4), access the »Control adjust« menu in the pupil transmitter and assign those inputs which correspond to enabled function inputs 5 … 12 as shown in the »Teacher/pupil« menu of 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 values entered in this position act as a quasi "limiter", whereby the setting is actually for which point of travel the respective servo may not exceed, so that it does not start up mechanically and thus unnecessarily draw current. In this case it is the end of available mechanical play on the servo, rudder and/or steering which is decisive for the value to be set.

An example of this would be the "dead" travel of spoilers.
Integration of an electric drive into the model programming 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 joystick (C1). However, since this is already specified for the brake system in the course of the model programming described above, either the switchable solution described beginning on page 279 or even the use of an alternative control is possible.

Control E-motor and crow alternately with C1 joystick Example 4 Before we discuss the programming of this fourth example or turn the to the expansion of the previously described basic programming, a few words should be said about the position of the throttle/brake joystick with "Motor OFF" or "Brake OFF". Normally the C1 control joystick is moved forward for the throttle control and backward for the extension of the brake.

As soon as you switch to the "Landing" flight phase, this flight phase timer is automatically stopped and hidden in the base screen. More about this can be found on page 156. Now move the marker frame over the "Ph.Tim" column to the "Motor" column to the right.
ailerons can be automatically suppressed. The suitable correction values for the respective value must be tested out through flight. Set this mixer so that the flight speed of the model does not change too much with the brake system extended in comparison with the "normal" flight speed. Otherwise, there is the risk, among other things, that the model plunges when the brake system is retracted, e.g. for the extension of a landing approach which is too short.
C1 joystick 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.

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 connecting the servos together on the model side using V-cable.

Using flight phases Up to 8 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.

Thus, an increased stress of the model under certain circumstances with a "hard" change of rudder or flap positions, for example, is prevented The "Status" column shows you the currently active flight phase with an asterisk "¾". nd 2 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 three-way switches is ideally suited for switching between up to three flight phases.
Here, select the "Copy flight phase" menu item with the selection keys then briefly tap the center SET key of the right touch pad. In the window which now appears, "Copy from phase", "1 Normal" is selected … Copy 1 normal 3 Speed 5 7 from phase: 2 Ther mal 4 Launch => 6 => 8 … and a subsequent brief tap on the center SET key of the right touch pad will change the display to "Copy to phase".

Example 2 … FL EL RU FL AI The following example is based on the assumption that you have already mechanically pre-adjusted the model and you have already ensured the correct deflection of all rudders or checked this again in the scope of this programming and made adjustments, if applicable, through servo switching at the receiver and/or through the »Servo adjustment« menu.

The mixing direction is to be selected so that all flaps are deflected downward with the elevator pulled up and deflected upward with the elevator pushed down (= hydroplane).

Since there is no particular priority here, assign for example switch "C" in the display to one of the two end settings of one of the two 3-way switches.
Now we will program the required settings in the flight phase "Thermal" as an example. In order to vary camber flap positions in the «Thermal» phase, it is merely necessary to switch over to the menu … »Control adjust« (page 108) … then change Input 6 – as described beginning on page 108 – from "GL(obal)" to "PH(ase)" and finally assign it to an operating element. To do this, first use the selection keys to switch into the "Typ" column for "I6" and change this setting from "GL" to "PH".
A simultaneous tap on the cd or ef key combination of the right touch pad (CLEAR) will reset changed values back to their standard default values. Note: Due to the improved lift distribution, the degree of mix ratios should be set so that the camber flaps are slightly "lower" than the ailerons. With a simultaneous tap on the ef keys of the left touch pad, the reaction of the AI and FL servos can be checked in the »Servo display« by actuation of the selected camber flap control.

Brake settings Note: The "Brake settings" menu is switched "off" if: "Motor on C1 forward / back" in the »Model type« menu, page 94, AND the "Motor" column of the »Phase settings« menu, page 142, are set to "yes" for the currently active flight phase. Change the flight phase, if applicable.
right Delta and flying wing models differ significantly from a "normal" flight model due to their unique characteristic shape and geometry. The differences in the servo arrangement, on the other hand, are more subtle. For example, with "classic" delta/flying wing models, only two rudders are normally provided. They are responsible for both "transverse" and "height/ depth", like the side rudder/elevator function on a V-tail unit.

Vertical ascent and descent Some models have a tendency to deviate from the ideal line in vertical ascents and descents. In order to compensate for this, it is necessary to have a center position of the elevator dependent on the throttle joystick position. If, for example, the model begins to hold off on its own in the vertical descent with a throttled motor, some elevator must be mixed in at this throttle position. For this purpose, program a free mixer "C1 ¼ Elev".
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.
