Introduction Thank you very much for purchasing the Graupner Receiver Falcon 12 plus HoTT 2.4 GHz 3 axis gyro with vario and diversity antennas. This receiver is extremely versatile. It could be also flashed with a Quadrocopter flight control software and together with the GPS S8437 it does activate the functions Autopilot, Coming home and waypoint flying. Read this manual carefully to achieve the best results with your receiver and first of all to safely control your models.
Intended use More punctual information about receiver can be found in the Technical data section. The receiver is designed exclusively to be used in battery-powered, radio controlled models, any other use is not allowed. For any improper use no warranty or liability is accepted. Read through this entire manual before you attempt to install or use the receiver. Graupner/SJ constantly works on the development of all products; we reserve the right to change the item, its technology and equipment.
Symbols explication ! Always observe the information indicated by this warning sign. Particularly those which are additionally marked with the CAUTION or WARNING. The signal word WARNING indicates the potential for serious injury, the signal word CAUTION indicates possibility of lighter injuries. The signal word Note indicates potential malfunctions. Attention indicates potential damages to objects.
Due to safety and licensing reasons (CE), any reconstruction and/ or modification of the product is prohibited. Only use the components and spare parts that we recommend. Always use matching, original Graupner plug-in connections of the same design and material. Make sure that all of the plug-in connections are tight. When disconnecting the plug-in connections, do not pull the cables. Protect the receiver from dust, dirt, moisture and foreign parts.
Installation Fixed-wing model The receiver must be aligned at right angles to the model on the receiver platform. The lower surface of the receiver must always be parallel to one of the model sides. Prior to installation, remove the sticker on the back of the receiver. We recommend using double-sided tape No.: S8376 for Gr-18 to fix the receiver in place. Also the so-called mirror adhesive tape is suitable.
Binding The binding is only possible if, since the switch-on of the receiver, it has not been bound to any transmitter (red LED on).
Power supply The receiver does not feature specific sockets for connecting the battery. We recommend that you connect the power supply to the socket(s) close to the servos already connected to the receiver. If you wish to connect multiple separate batteries, the batteries must be of the same nominal voltage and capacity. Never connect different battery types or batteries with strongly different charges since this can cause an effect similar to a short circuit.
Maximum altitude (Max. altitude) This is where you can specify a maximum altitude. When the model reaches this altitude, an alarm is triggered either by the transmitter’s RF module in the form of a “general alarm tone” (regular beeping at a rate of approx. one beep per second) or the “altitude” speech output message. Note: When the receiver is switched on, the model’s current altitude is set to 0; the displayed altitude is therefore the altitude relative to the launch point.
Programming a fixed-wing model Free mixers FREE MIXER < > >MIXER: 1 FROM CHANNEL: 1 >TO CHANNEL: 6 >TRIM: +0% TRV - : +100% TRV + : +100% Note If you wish to use the gyros, you must always set the tail type to ‘normal’ in the transmitter’s model type menu. If your model is a delta, features a V-tail, or has two elevator servos, you must use the receiver mixer - not the transmitter mixer - to control these control surfaces, since the gyro stabilization system will have no effect on these servos otherwise.
A ‘Rudder / elevator’ mixer can be set up at the transmitter instead of ‘Free mixer 3’ at the receiver; the mixer should be set up asymmetrically, e.g. +30%, -30%. This option frees up one mixer at the receiver.
Gyro assignment Axis assignment < > Axis assignment < > >AILERON SERVOS: 2 >AILERON SERVOS: DO SETUP: yes DO SETUP: No AILE: (right) ELEV:(push) RUDD:(right) +2 +0 +0 AILE: (right) ELEV:(push) RUDD:(right) +2 +1 -3 2 Aileron servos: You should enter the value 2 in this line if your model has two aileron servos. In this case the gyro for channel (servo) 2 also acts on servo 5. If the ailerons are also used as flaperons or speedbrakes, gyro suppression is based on the sum of both channels.
! Elevator CAUTION Movement of the model Control surface action (tail view) Check that all the gyros are working in the correct direction! Move the model in all axes directions. Check the movements and travels. Now check the control surface deflections - see diagrams below.
Note Before you start entering settings for a new model, it is essential to select the number of aileron servos in the Aileron servos menu point, and to define the gyro axes and orientation in the New settings menu point.
Note If the model is too agile in mode 3, it is then recommended to set in the transmitter DUAL RATE and/or EXPO for this mode. Thus the model will react in a more docile way. In the Rate mode the model tries to reach the controlled rate. Also in mode 2 EXPO can be useful. Aileron/elevator/rudder: Shows the programmable factors for the corresponding control surface. The gyro correction can also be disabled by setting the value to "OFF".
Flight phase specific settings It is possible to use a channel to control the factor value by setting up flight phase specific transmitter control settings, but only with some transmitters; please see the instructions supplied with your transmitter and refer to the “Transmitter control settings” and “Flight phase settings”.
4. First select a low value (see value section for starting points) and carry out a test-flight. If gyro stabilization is not sufficiently pronounced, increase the value step by step until the level of correction is as required; if the model already oscillates, reduce the value step by step. 5. Move on to "elevator" or "rudder" and select the desired value (or OFF). 6. Leave the settings for “Factor” to OFF. 7.
Programming a helicopter model Preparing the helicopter Transmitter presettings Set all servos to neutral; the arms must be at right angles and the swashplate must be in the neutral position (perpendicular to the main rotor axis). The swashplate pushrods must be the same length. Select the free/deleted model memory and activate the helicopter model. Set the pitch front/back according to your personal preferences and do not change it anymore.
Basic settings Procedure 1. Once the transmitter and helicopter have successfully been prepared, call up the Telemetry menu in the transmitter (see transmitter instructions). 2. Set in the receiver the model type "Hely" (see section "Receiver settings"). Then change to the menu "Base setup contr.". 3. Scroll past the swashplate/tail setup menus; these will be used later on. 4. You must work through each item of this menu in order from top to bottom: Base setup controller BASE SETUP CONTR.
Swp frequency Swp frequency: frequency for the swashplate servos 50-200, default setting: 200 Hz Warning: Analogue servos may only be operated at 50 Hz. If they are not, the servos will be destroyed. Many digital servos can be operated at a higher frequency. (Use at your own risk). This allows the model to be controlled more quickly. With HBS servos, we recommend setting the frequency to 200 Hz.
Collective_A/B 50-120, default setting: 80 It is selected automatically based on the pitch stick travel on the transmitter. Use the pitch gauge to measure the required pitch travel when the full commands are applied (+-100%) and set it in this menu. All of the other settings can be made later on the transmitter for the pitch curves in the respective flying phase. Swp limit 50-200, default setting: +80 Swashplate limit.
This allows the model to be controlled more quickly. With HBS servos, we recommend setting the frequency to 333 Hz. Tail center -100 - +100, default setting: 0 If the value "Value tail center" (inverted field) is activated, the tail servo moves to the neutral position. The tail servo arm should be at a 90-degree angle to the tail linkage pushrod. The fine trim is then adjusted based on the mid-point of the tail. When the servo is set to neutral, the tail rotor should have a pitch angle of approx.
Axis assignment Axis assignment >DO SETUP: Roll (right): >Nick (push) >Tail: (right Axis assignment >DO SETUP Roll (right): Nick: (push): >Tail (right): DO SETUP < Yes +2 +0 +0 < No +2 +1 -3 DO SETUP: Yes/No Assignment of the gyros and their operating direction. If you have not already done so, you must now set the C1-4 servo directions so that everything works correctly. In the receiver's "Axis assign" menu, go to the "Setup" option and set it to "Setup: Yes".
Checking nick Tilt the helicopter so that its nose is facing downwards; the swashplate moves consequently backwards. Incorrect! Right! Checking roll Tilt the helicopter to the right; the swashplate moves consequently to the left. Checking the tail direction of operation This effect depends by the helicopter, the left-hand or the right-hand rotator, as well as the side and the direction of rotation of the tail rotor. Refer to the heli's instructions for this information.
Swp rate 50 -120, default setting 85 Sets the max. potential rate of rotation in Rate mode for roll and nick. Expo Swp 0 -50, default setting 15 You can set here an exponential curve (0 - 50%) for the rate of roll and nick. Low percentages result in a linear increase in the rate of rotation. High percentages a strong curve, the heli then no longer reacts so sensitive to the center of the stick. We recommend to use the Expo in the GR18 or in the transmitter.
The I-factor ensures constant rolling/nicking. Start with low values and only increase them until the roll and nick rates are constant. D swp (differential) D-factor for swashplate 0 - 70, default setting: +40 The D swp D-factor influences the how the swashplate is stopped. If the helicopter bounces somewhat when nick is stopped, this parameter should first be increased in small increments to test the nick stop.
If you want to use the Anti-ballooning compensation, start with the value "30". A reduction of the parameter eg to the value "25" increases the "rearing" tendency. An increase to, for example, "35" reduces the tendency but can also adversely affect the final speed. You need to find an optimal compromise between safe flight behavior without rearing and maximum speed. For this, first start in 5 steps and then make the fine tuning in 1 steps.
Tail rotor setting with Expertmode (See above for tail sensitivity menu item) P tail Tail rotor adj. >Tail sensitiv.(5)C9 Tail rate +85 EXPO tail +40 P tail +80 I tail +70 D tail +15 Pitch->Heck +25 Tail P-factor 40-125, default setting: +80 The P tail option is responsible for effecting a harder stop with the tail. Higher values result in a faster stop. If the P values are too high, the tail will start to "oscillate". In such cases, the value must be reduced again.
Tail dynamic 10 -100, default setting: 65 Higher dynamic values provide a more direct control feeling, lower values result in a smoother control feel. If the values are too high, the tail does not stop and it can overflow. If the values are too low, the control behavior becomes softer. Vibration damping YES-NO, default setting: NO The vibration damping automatically detects emerging vibrations at the tail rotor, e.g.
Firmware update Updates to the receiver’s firmware are made via the output channel 5 / telemetry socket using a PC running Windows. You will also need a USB interface, order No. 7168.6, and adapter lead, order No. 7168.6A or 7168.S, which are available separately. The programs and files required can be found in the Download area for the corresponding products at: www.graupner.de Connect the adapter lead to the USB interface No. 7168.6.
When the file has loaded, click on start... ... connect the receiver and switch it on. The progress bar shows that the transfer is running normally. The receiver LED lights up red during this process and flashes once the transfer is completed. Please refer to the detailed update instructions for the item in question in the Download area at www.graupner.de.
