Routing the receiver's antenna The receiver and its antennas must be positioned as far away as possible from drives of any kind. If the model's hull is made of carbon fiber material, the ends of the antennas must extend outside of the hull. The orientation of antennas is not critical. Nevertheless, a vertical (upright) installation of receiver antennas is advantageous. In the case of diversity antennas (two antennas), the second antenna should be oriented at a 90° angle to the first antenna.
Safety notices are always to be followed, this includes mandatory adherence to the length of charging time. Never leave batteries being charged unattended. Never attempt to charge primary batteries (nonrechargeable batteries) because they can explode. All secondary batteries (rechargeable batteries) must be charged before every session.
transmitter and receiver. • Prior to every flight, perform a complete functional test, range test and execute a complete simulated flight in order to exclude the possibility of system faults or problems with the model's programming. • Never program the transmitter or receiver while the model is being operated. Care and maintenance Never clean the housing, antenna, etc. with cleaning agents, gasoline, water or similar means. Use only a dry, soft cloth.
Safety notices and handling instructions for nickel-metal-hydride rechargeable batteries As applicable for all highly technical products, observance of the following safety notices, along with the handling instructions, is essential for a long service life, fault-free operation, and harmless utilization. Safety notices • Individual battery cells and batteries are not toys and must therefore not get into the hands of children. Batteries/cells must be kept out of the reach of children.
supervision. If a suitable quick charger is not available on which the exact charging current can be set, the battery can be charged by standard charging according to the 1/10 C-method, see example above. Whenever possible, transmitter batteries should charged with the 1/10 C method because of the differing charge states of the cells. However, charging current may never be allowed to exceed the maximum permissible rate specified in the given transmitter's instructions.
mx-20 the newest generation of remote control technology HoTT (Hopping Telemetry Transmission) is a synthesis of know-how, engineering and testing done around the world by experienced model pilots. HoTT technology combines 2.4 GHz band transmission/reception with bi-directional communications via a "return channel" integrated into the receiver unit.

Operating notices Receiver power supply A selection of 4 and 5 cell NiMH battery packs having different capacities are available to power the receiver. If digital servos are in use, we recommend a 5 cell battery pack (6 V) to afford adequate battery capacity. If analog and digital servos are used in mixed operation, be sure to pay attention to the given maximum permissible operating voltage. A stabilized, adjustable power supply for the receiver with 1 or 2 receiver batteries can be provided, e. g.
Joystick length adjustment The length of both joysticks can be continuously adjusted to adapt these transmitter controls to the pilot's preference. Hold the lower half of the knurled grip in place then turn the upper section to release its counter-locked threads. Now pull up or push down on the joystick's end to the desired length. When the length is suitable, tighten the counter-locked threads of the upper and lower sections again.
Operating notices Converting joysticks Neutralization Both the left and the right joystick can be configured for neutralized or non-neutralized operation as desired. Open the transmitter housing as previously described. To change the joystick's factory setting, locate the screw shown in the figure below enclosed in a white circle.
Brake spring and ratchet The outboard screw of the two marked in the next figure adjusts the braking force and the inboard screw adjusts the strength of the ratchet for the respective joystick. Joystick restoring force The joystick's restoring force can also be adjusted to the pilot's preference. The adjustment is located next to the return springs, see markings in the figure below. Spring force for the given direction of motion can be adjusted by turning the respective screw with a Phillips screwdriver.
Transmitter description Transmitter operating elements Attaching the transmitter's neck strap There is an eyelet on the top side of the mx-20 HoTT transmitter (see figure at the right) to which a neck strap can be attached. This anchor point has been chosen because the transmitter is optimally balanced here when it hangs from the strap. Order No. 1121 Neck strap, 20 mm wide Order No.

Putting the transmitter into operation Preliminary remarks about the mx-20 HoTT transmitter Preliminary remarks Graupner's 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.
Transmitter firmware updates capable of operating up to 12 servos. In order to achieve the greatest possible flexibility but still preclude unnecessary inadvertent operator errors, control channels 5 … 12 have not been assigned to any controls. This means that servos connected by way of these channels will remain in their middle positions until an operator element has been assigned. Practically all mixers are initially inactive for this same reason.
Now in the "Port select" window, select the COM port connected to the USB interface. The correct port can be recognized by its designation "Silicon Labs CP210x USB to UART Bridge" in the "Device Name" column. In the above example this would be the "COM 3" port. Now call up menu option "Firmware Upgrade" from "Menu" or open the "Controller Menu" and click on "Firmware Upgrade". the desired firmware update file with a ".bin" filename extension from the "Open file" window.

Receiver initialization Preliminary remarks about the GR-24 receiver Receiver system The mx-20 HoTT remote control set includes a type GR-24, 2.4 GHz bidirectional receiver for connecting up to 12 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 firmware updates Please note the following: A receiver RESET will cause ALL receiver settings - except for binding information - to return to their factory settings. Therefore if a RESET is triggered unintentionally, any custom settings that had been present in the receiver before the reset will have to be established again by way of the Telemetry menu. A deliberate RESET is recommended, especially if a receiver is to be "transferred" into another model.
Typically this file can be found in the folder whose name is prefixed with the order number of the receiver to be updated. This folder should contain the ZIP file that was downloaded and unpacked. Its filename should also be prefixed with the order number of the receiver to be updated. For the standard GR-12 receiver included in this set, the folder would be designated "33512_12CH_RX". The filename will appear in the corresponding window.
Both LEDs on the receiver will illuminate during the update process. Upon successful conclusion of the update process, the green LED will extinguish and the red LED will begin to blink. Switch off the receiver, remove the interface cable and repeat the process for any other receivers you have which must be updated. 4. Receiver initialization Following a successful update process you MUST perform a receiver initialization procedure before using the receiver again. This is necessary for reasons of safety.
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.
Receiver system 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.
for example, NiMH batteries. LiPo batteries are also available in hard plastic casings to protect them from mechanical damage. The comparatively high nominal voltage, 7.4 V, for a 2-cell LiPo pack does not present a problem for either Graupner HoTT receivers nor for those servos, speed controllers, gyros and other devices which have been specifically approved for operation in this – higher – voltage range.

Term definitions Control function, control, function input, control channel, mixer, switch, control switch, fixed switch To make use of this mx-20 HoTT manual easier, a number of the terms used repeatedly throughout this manual have been defined below. Control function A "control function" is a signal intended to affect a given control action – initially independent of its signal course in the – .
Fixed switches FXI and FX This type of switch turns a function permanently on, e. b. timers (closed fixed switch) or off (open fixed switch) or they can provide a fixed input signal for a control function, e. g. FXI = + 100 % and FX = -100 %. For example, in flight phase programming, these fixed switches can be used to switch a servo or speed controller between two settings.
Physical control, switch and control switch assignments Principle procedure The mx-20 Hott system exhibits maximum flexibility when it comes to assigning standard equipment operating elements to specific functions.
Control/fix sw C1 C2 C3 C4 FX FXi C1i C2i C3i C4i Use the arrow keys in the left or right key pad to select the desired switch then assign it with a brief tap on the center SET key of the right touch pad. Notices: • The two FX switches turn 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.
Digital trim Functional description and description of C1 cut-off 54 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.

Helicopter models The advanced developments incorporated into the transmitter as well as those now in helicopter models and their components like gyros, speed regulators, rotor blades, etc. make it possible to master a helicopter even in 3D acrobatic flight. On the other hand, a beginner needs only a few settings to get started with hovered flight training and then can take advantage of mx-20 HoTT features, step-by-step, with increasing expertise.
Notice for those transitioning from older Graupner systems: In comparison to previous receiver layouts, servo connector 1 (pitch servo) and servo connector 6 (throttle servo) have exchanged places. Servos must be connected to receiver outputs as illustrated at the right in the bottom figure. Outputs which are not used are simply left empty. More details about respective swashplate types can be found on page 86 in the "Basic settings" menu.

How do I program a flight phase? 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. takeoff, approach, hover, auto-rotate, etc.). With mx-20 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" – i. e. also "after" transmitter control options such as e. g.

connected to outputs 9 and 10 – assuming that corresponding flaps have been specified on the "Aile/flaps" line on the "Model type" menu. This transmitter control indirectly controls the flap position of the ailerons via the percentage value entered in the "Ail" (and "Ail2") column on the "FLAP" line of the multi-flap menu. To be able to provide more fine-grained control of flap positions, however, you should reduce travel to about 25% on the "Input 6" line of the "Control adjust" menu.
Mixer functions The individual options on the "Wing mixers" menu option are discussed below, separately for single-, dualand multi-flap models. Before we start, a number of remarks on the differentials for ailerons and flaps: Aile. diff. or Diff.

Diff. (camber-changing flap differential) AI Ail-tr Diff. fl.pos Normal 0% 0% 0% 0% FLAP AI Ail-tr Diff. fl.pos Normal 0% 0% 0% 0% FLAP2 In the "AI" line on the multi-flap menu, you can set the extent to which the flaps act as ailerons and follow the aileron joystick; the value is entered as a percentage. The flaps differential – to be set on the line "Diff." (two lines below) – works in a similar way to the aileron differential, i.e.
direction of deflection as appropriate. Optionally, this mixer can be activated and deactivated by using one of the switches that do not reset themselves (SW 2 … 8) or a control switch. This means you can then also control the model using only the ailerons or rudder, as required. Typically, this mixer is set so that the rudder is deflected to the same side as the upward-oriented aileron, and you will find that setting a value of around 50% is usually highly appropriate.
Here, you can set the degree to which the rudder follows commands acting on ailerons. This is used in particular in connection with aileron differential to suppress adverse yaw and thus make it easier to fly "clean" curves. You can of course still issue separate commands to the rudder. The adjustment range of ± 150% lets you set the direction of deflection as appropriate.

Detail program description - Control adjust program offers a much more flexible approach to finetuning and optimizing increases to system rotational speed below the hover point than the "idle-up" approach taken by older mc radio control units. Ensure that the throttle limiter is closed before you start the carburetor motor, i. e. so that the carburetor can be adjusted within the idle range only by using the idle trim. Ensure that you follow the safety instructions on page 177 at all times.
control turned fully to the left; the motor will be idling and respond only to C1 trim. This option permits you to start and also stop the motor from within any flight phase. Once the motor has started, turn the throttle limiter slowly in the direction of the opposite end-point, so you can once again activate the throttle servo fully using the throttle/collective pitch stick. To stop the throttle limiter limiting the throttle servo at its top endpoint, you should access the "Th.L.

that the deflections for roll and/or pitch-axis exploit the maximum travel mechanically possible, e. g. for 3D helis, then the total tilt applied to the swashplate if full roll and pitch-axis commands are applied simultaneously will be considerably greater (141% in numerical terms). The swashplate mechanism may then strike its endstops and in the worst case the ball-links could even be disengaged.
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. For some special cases, however, e. g. for "3D" flight, you may wish to program hover points that deviate from this standard. For example: one point for normal flight attitude above the center and one point for inverted flight attitude below the center.

hovers below the mid-point, correct this by reducing the angle of attack appropriately. You may also find that it is necessary to correct the carburetor opening for the hover point (point "1") at "C1 throttle". This diagram shows only the change to the hover point, i. e. collective pitch minimum and maximum are both left at -100% or +100%.
Helicopter mixers Auto-rotation settings 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. Accordingly, switchover TO the autorotation phase takes place immediately.
value on this line so that a glow motor is held at a safe idle during the auto-rotation phase without the clutch engaging; electric drive systems should be set safely to "Off". Note: You may wish to make use of the "Motor Stop" option on the "Base setup model" menu as an alternative "Emergency STOP" function. Depending on the friction and running resistance of the gearbox, the fuselage may still yaw slightly, however.

Timer confirmation with control or switch Examples 4 and 5 of the preceding pages If you have decided to continue with the model programming on described on the previous pages for Example 4, page 247 or 5, page 250 or you intend to use the C1 joystick (throttle/brake joystick) for the power regulation completely independently of this example programming, you can use a control switch for the automatic starting and stopping of the timer.

The switch status is shown to the right of the control number: CONTROL SWITCH ––– C1 Ct6 –85% C2 0% ––– ––– C3 0% C4 0% ––– STO SEL Notice: Now place the switching point; but do not put it at the limit position of the control, because safe switching is not assured when doing so. Ct1 used in the example here should be "closed" in the "full throttle" direction and "open" below the switching point.
Servos running in parallel 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.

Two rudders We want to switch two rudders "in parallel". The second rudder is located at the free receiver output 8.
Use of flight phases Up to seven different flight phases (flight statuses) can be programmed with settings independent of one another within one of the model memories. Each of these flight phases can be called with a switch or a switch combination. This makes it possible to switch between different settings for the various flight statuses, such as "Normal", "Thermal", "Speed", "Distance", etc., simply and conveniently. However, with the flight phase programming you can also make slight modifications, e. g.
to enable a "smooth" transition of the various servo positions. 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 "". 2. Step In order to actually be able to switch between the individual flight phases, the assignment of one or multiple switches is necessary.
Here, select the menu item "Copy flight phase" with the arrow keys and then briefly press the central SET key of the right touch pad. In the appearing window, "Copy from phase", "1 Normal" is selected ... Copy from phase: 2 Thermal 1 Normal 4 Launch 3 Speed => 6 5 => 7 … and then briefly press the central SET key of the right touch pad, whereby the display switches to "Copy to phase".

Use of flight phases Example 2 … Glider with four flap wings, two large flaps and tow coupling AI FL EL RU FL AI The following example is based on the assumption that you have already mechanically preadjusted 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 setting" menu.

Control of temporal processes using time delay and curve mixers A useful, but less known capability of the mx-20 HoTT software is the ability to activate nearly any servo movements with a maximum duration of 9.9 seconds using a switch. The programming for this should be shown on the basis of some examples in the following. Additional applications can certainly be found once you become familiar with these capabilities.

Eight-flap wing By standard the mx-20 HoTT supports the comfortable control of up to eight servos for the aileron/ camber changing flap functions. In the following we will consider a model without motor drive and without spoilers in the wings.
… if necessary. In doing so, the basic programming of the eight-flap wing is completed. Camber changing flap positioning and flight changes First program two or more flight phases in the "Phase setting" and "Phase assignment" menus. On this occasion, also change the standard default "Global" to "Phase" in the "Joystick setting", page 92 for the effect of the digital trimming, if applicable, on your individual requirements. An example of flight phase programming can be found on page 256.

11 + 12 extend upward and the camber changing flap pairs "FL" (6 + 7) and "FL2" (9 + 10) extend downward, whereas the elevator is trimmed in parallel to this, see page 162. In order for the brake system to react to the C1 joystick as desired, however, the mixer neutral point (offset) of the brake system must be adjusted accordingly. This takes place in the menu … "Model type" (page 82) After selection of the line "Brake Off.
Delta and flying wing models Of course, the general comments regarding the installation and the adjustment of the RC system to a model at the beginning of the wing model programming on page 236 also applies for delta and flying wing models! Similarly, the comments for test flying and finetuning the settings to the programming of flight phases also apply.

For example , the "lifting" moment caused by the raising of the ailerons (= elevator effect) can be compensated for with camber changing flaps lowered correspondingly wide ( = hydroplane effect).
In order to now achieve this with the mx-20 Hott, switch to the "Brake settings" of the … "Wing mixers" menu (beginning on page 146) … and enter the values for the ailerons to be raised and the "flaps" to be lowered in the "Crow" line so that the occurring moments compensate one another and the altitude of the model remains stable.

F3A model F3A models are a part of the group of motor-driven winged models. They are powered by a combustion or electric motor. Models with electric motors can be used in both the electric acrobatic class F5A and are also competitive in the international model acrobatic class F3A. for the carburetor can – if necessary – be provided. You normally use one of the two proportional rotary controls on the transmitter, which actuates one of the unassigned auxiliary channels. Free or aux. function Free or aux.
After test-flying and trimming of the model, we recommend reducing the trim travel for the elevator and ailerons The model has significantly less of a reaction to a movement of the trim lever. "Overtrimming" can be avoided, because with full trim travel, under certain circumstances, the movement by just one trimming step can have too strong of an effect: Therefore, the model which previously pulled slightly to the left, hangs somewhat to the right after the trimming. For this purpose, switch to the menu ...
Basic procedure: • Move the C1 joystick and, along with it, the vertical line in the graphic display toward idle to -50 % control travel and briefly press the central SET key of the right touch pad. • In order to attain the curve shape shown, raise this point with the arrow keys to approx. 0 % in the inverse value field of the "Point" line.
Asymmetric setting. The appropriate values must be tested in flight. Relatively small mixer values are usually sufficient in this case, the range lies below 10 %, but can vary from model to model. With the use of curve mixers, the mix ratios can be adapted even more precisely to the corresponding throw of the rudder. Again, no values are indicated for this, because this would be model-specific.
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.
change these in the adopted defaults "Stick mode", "DSC output" and "Pitch front/rear" as well as within the respective model memory location. The setting the "Contrast" line determines the legibility of the display under poor light conditions and the setting in the "Display light" line determines how long the display lighting remains illuminated after the transmitter is switched on or after the last key actuation.

If ever, this curve should only be applied "cautiously" at the very end, when all adjustments have been made. It should never be used for the throttle/pitch adjustment! The overlappings result in "nasty" effects.
The assignment of the switch takes place in the menu … "Phase assignment" (page 134) Under "C" and "D" assign the three-stage switches SW 4 + 5, for example: PHASE ASSIGNMENT combi prior C D E F A B 4 5 2 1 Normal Now you must assign the corresponding flight phase from the "Phase setting" menu to the respective switch position. Since you have already assigned names, the name of the phase "1 Normal" appears to the right in the display.
Enhancement recommendation: Rotational speed regulator At some point in time you may want to install a rotational speed regulator in the helicopter, such as mc-Heli-Control, 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.
