  • Page 5: Scope Of Application

    1. General considerations. The Weatronic 2.4 Dual FHSS line has been developed in Germany by a selected team of electronic and signal engineers as well as IT experts. The system has evolved over the years to stay at the leading edge of today’s technology and is manufactured to the highest quality standards using some of the most advanced components.

  • Page 6: Receiver Package Contents

    2. Receiver package contents. The Micro receiver package contains the following components: . The receiver. . A SCU plug jumper. . A quick setup user manual. © Olivier Nicolas Micro user manual rev 4, 26 Oct 2014 p 6...

  • Page 7: Safety Considerations

    Keep you model within the sector allocated for flying in and never over-fly spectators, other pilots or anyone else who may be in the vicinity. The Weatronic 2.4 Dual FHSS system can safely be operated along-side transmitters using the 35 or 72 MHz bands with no risk of interference.

  • Page 8: System Description

    There are millions of different codes available. Interference or probability of being hacked by another system is nearly impossible. It is safe to use up to 120 Weatronic systems simultaneously in the same area together with old narrow band (35 or 72 MHz) transmitters.

  • Page 9: Power Bus And Gyro Considerations

    The description of all of the GigaControl software/ BAT transmitter functions is detailed in a separate user manual. 4.5. Transmitter system considerations. The Weatronic system can operate from both a specific DV4 antenna module that plugs into the existing transmitters like the Taranis unit, or the dedicated Weatronic BAT transmitters.
  • Page 10 DV 4 Modules are currently available for the following transmitters: • Futaba T12 FG/T14 MZ/FX-30/FX-40 • Futaba FF 7/FF 9/FF 10/WZ-2/FC-18/FC-28 • Multiplex Royal Evo/Royal Pro/Profi MC 3010/3030/4000 • Graupner MC19/MC20/MC 22/MC 22S • Graupner MX 22/MC 24/JR 9X/JR 10X, JR12X •...

  • Page 11: Receiver And Associated Accessories Setup

    5. Receiver and associated accessories setup. Our Micro receivers have been thoroughly tested to the most stringent levels of vibration and temperatures. However they should always be mounted as far away as possible from known sources of heat or vibration, like engine exhausts. 5.1.

  • Page 12: Routing The Micro Receiver Antennas

    5.2. Routing the Micro receiver antennas. The receiver is fitted with 2 shielded wire antennas. They should be located as far from each other as possible at an angle of 90 degrees. The antennas must stay straight and we recommend mounting them into plastic Bowden tubes (NOT carbon fibre!) for protection and guiding.

  • Page 13: Plugging Your Servos

    5.4. Plugging your servos. 5.4.1. Power rail considerations. The power rail can handle 5 amps max. This means that you can drain up to 10 amps if plugging a battery on each side of the rail. That can be on servo 1 and bat port of your receiver. 5.4.2.

  • Page 14: Setting Up Telemetry And Sensors

    5.5. Setting up telemetry and sensors. A broad range of telemetry sensors are available from Weatronic. Some are specialized items. For example the variolink unit for gliders. The sensor readout needs to pass by the SCU plug of the receiver. Some sensors can be plugged directly to the SCU port, whereas some other need to be interfaced on a serial unit called the Muxbox.

  • Page 15: The Pitot Tube Device

    On this picture you can see the black "batt" cable at the bottom that goes to the receiver Y servo cable ( power supply ). The blue plug goes to the SCU input slot of the receiver. Once the MUX box is connected to the receiver, power up the system. You will see the MUX box green and red LEDs flashing for a little while and then, the red should extinguish and the green become steady.
  • Page 16 The back of the pitot tube will be connected to the pressure sensor by two very tiny silicone tubes. One is blue and connect to the blue nipple, whereas the other one is white and connects to the non colored nipple. It is essential to ensure that the silicon tubes are not pinched when installing them.
  • Page 17 The servo plug has to connect to the A1 input of the MUX box as this is the only input that accepts this device. The pitot tube has to be installed in a free flow environment, as streamlined as possible and at least 40 cm away from any fuselage surface.
  • Page 18 When all the connection is done, enable the pitot sensor in the MUX box tab under sensor A1. The sensor name is 250 km/h pitot speed sensor. 5 Hz sampling rate should be enough for most users ( 5 readings per second ). Note that the 450 km pitot is the same device with the little tab at the bottom of the cube welded.
  • Page 19 Here is an example of a flight with the pitot tube speed. It is the red curve on the bottom window. If you want to monitor your approach speed at 1,3 vs and get the system to give you a caution when you reach this speed,we would highly recommend the use of the pitot tube.
  • Page 20 Additionally you can use the device to monitor your speed in flight and give you a warning when approaching a stall condition. We typically recommend to setup the voice output for the pitot tube as followed: Control channel= flaps 1. flaps up: minimum speed caution at 1,3 Vs 2.

  • Page 21: The 125C Temperature Sensor

    5.5.3. The 125c temperature sensor. It is a tiny device that can plug on any analog input of the MUX box ( A1 to A4 ). Once you have plugged the device and installed it in the fuselage, you can configure the MUX box tab. Here is an example where the temperature sensor is set on A2. Then select some sample rate to enable the sensor: Using this sensor can be useful to monitor a fuselage temperature at the back of the turbine.

  • Page 22: The Egt Sensor

    5.5.4. The EGT sensor. A chromel/ alumel sensor that reads temperatures up to 1000c is available from our shop. This sensor plugs on the specific port of the MUX box labeled "PT 1000". The sensor is configured from the PT 1000 entry of the MUX box tab of Gigacontrol. 5.5.5.

  • Page 23: Software Configuring Your Receiver

    5.6. Software configuring your receiver. Although your receiver comes loaded with a factory configuration, many important parameters can be modified and tuned according to your model and type of operations. The parameters governing the operating conditions of the receiver are available from the “receiver configuration” tap of Gigacontrol and under the menus “model setting”...

  • Page 24: Gigacontrol Settings

    5.6.1. Gigacontrol settings. The user settings are displayed with a slider. To adjust them, simply move the sliders. The modified value will show on the left side of the slider. Every parameter in this window is associated with a specific LED/ beep warning pattern an voice message if enabled. Battery warning is the threshold set to trigger a warning if the main battery voltage drops below the defined value.

    • BINDING button, press here to start the binding process. The BAT 60 will start to search for Weatronic receivers which are within range and in binding mode. You will see a progress pop-up. The pop-up will disappear when the binding process was successful or if you press the “Binding Stop”...

  • Page 26: Receiver Firmware Updating

    5.7. Receiver firmware updating. The receiver is always coming with the latest firmware pre-installed. However, we recommend that you install any new firmware when it becomes available. A specific USB firware loader is required for this purpose. Before doing so, please backup the receiver configuration file via Gigacontrol or the BAT transmitter. 5.7.1.

  • Page 27: Load The Firmware

    Prepare a fully charged receiver battery. 5.7.5. Load the firmware. On the PC, click on the "update" button of the GigaUpdate windwo. The program will try to connect to the receiver and display " Connecting to target". Within 5 seconds plug the receiver battery. As you do so, you will see a window popping up asking for upgrade confirmation.

  • Page 28: Post Upgrade Procedures

    It will then upload the new firmware. The red status LED will show solid as long as the firmware upgrade is in progress. The program will then advise of the firmware upgrade completion. You can now power the receiver down and unplug the USB loader device. 5.7.6.

  • Page 29: Batteries And Cables Sizing Considerations

    6. Batteries and cables sizing considerations. 6.1. Battery backer considerations. This receiver is not equipped with any voltage regulator or battery backer system. You can choose to use one or plug batteries on each side of the power rail. If this is the case, it is imperative to use the same type and size of battery to avoid cross feeding. In this situation, we strongly recommend a two A123 2 cell pack configuration.

  • Page 30: Micro Receiver Operations

    7. Micro receiver operations. 7.1. General. Our professionally developed Micro receivers are using high frequency micro processors that make the Weatronic 2.4 Dual FHSS system together with the Weatronic BAT transmitter an incredibly reliable and powerful combination. To get the best performance out of your system you will need a laptop or PC loaded with our GigaControl software or any browser based system connected to the BAT server.

  • Page 31: Quick Binding

    7.4. Quick Binding. As the serial number of each binded Micro receiver is stored within the module’s memory, re-binding (quick Binding) a receiver is extremely quick and easy. Simply switch on the transmitter, followed by the receiver and once the self test is complete press “Button 2”...
  • Page 32 This angle should give some indication on the masking components within the aircraft if the range is not adequate. After a “live” range test it is a good practice to review the data recorded on the memory card. Write down the RSSI value at which the system fail safes or Rx frames reach 0. This will give you a very good indication of the range margin you’ll get during subsequent normal flights.
  • Page 33 The RSSI information is interesting since it will show the masking of the antenna while turning the model at the limit of the range scale. The Rx frames information is the important one. As soon as frames for any one antenna drops to 0% the maximum range is reached.

  • Page 34: Advanced Range Testing And Antenna Placement Optimization

    7.6. Advanced range testing and antenna placement optimization. This is a very comprehensive test that will deliver precise data but will take a longer time to complete. We recommend doing it with big, expensive or professional models like jets, giant gliders or UAV.

  • Page 35: Range Test Procedure

    7.6.2. Range test procedure. This is the same procedure as explained above. It shall be done with an assistant. The key point, as explained previously is to deflect a control for each step away from the model, then to deflect another control while turning the model. As suggested previously, we recommend using the ailerons while walking away and then the elevators while turning the models for range evaluation.
  • Page 36 The log of an advanced range check. The green servo 2 curve shows the aileron deflection. The blue servo 4 curve shows the rudder deflection made in 4 phases during the rotation of the aircraft on the yam axis. Note the shape of the RSSI curve that will be translated on a polar graph.
  • Page 37 Altough one assistant would be enough to perform the test on the yaw and roll axis, two people may be required for the roll axis on medium and large ones. The range check shown previously is zoomed in and cut into four 90 degrees segments. It is then reported into a polar graph. Here is another example of a range test conducted on a large jet.
  • Page 38 The same diagram has been zoomed in to show only the rotation of the aircraft and cut into 4 quadrants. Note the quadrants numbered here in red. When you have done this for both antennas you will see the weak antenna directions. What is very important is that these directions do not coincide.
  • Page 39 A large jet model antennas horizontal polar coordinates diagram is shown here. The top of the diagram relates to the front of the aircraft. This represents the antenna strength for each quadrant as split on the previous schematics. The directions where the reception will be the weakest are the 6 o’clock ( back of the aircraft ) and 1 to 2 o’clock sectors.

  • Page 40: Range Limit Considerations

    7.7. Range limit considerations. Range limit warning can be programmed in the receiver page of Gigacontrol or the BAT transmitter. The minimum range warning will occur when either LQI reaches the specified value. We recommend setting the range warning value at 40% of LQI to stay on the safe side and get some large buffer margin.

  • Page 41: Data Log Analysis Considerations

    7.8. Data log analysis considerations. Analysing the data log after each flight is recommended. This will enable you to understand how your system performs in a specific airframe and characterize the weak reception spots in order to improve the antenna placement. The log shall be made readable by configuring NavView in a certain manner that will enable you to compare flights with each other.

  • Page 43 You should end up with the following display: You can now load the nav file by hitting the "open" button and selecting the file target. The data log will open automatically. Center the graph to the flight zone ( you will recognize it since the RSSI start to drop when the plane goes away from you ) and zoom it to get rid of the post and pre flight data.
  • Page 44 This option will enable you to evaluate the values compared to their maximum. It is very important to select this option otherwise the graph will not "talk" to you. The program is configured to show the "visible values" by default. If you see a zone of the flight that you want to evaluate more precisely, then center it on the dotted line, dragging the horizontal button.
  • Page 45 The line at 317s is automatically displayed in the left panel and highlighted in light grey color. You can then read the values... Note that the RSSI values can fluctuate between -110 dBm and -8 dBm, -8 dBm being the highest value ( best reception ). There are 100 frames per second of which 45 source frames ( flight orders ) .

  • Page 48: Telemetry And Voice Read Back Considerations

    7.9. Telemetry and voice read back considerations. It is recommended to enable the voice readback by installing the English voice file on the DV 4 module. The system voice warning should be enabled. This will send you system warning according to the receiver configuration parameters explained above in chapter 5.6.

  • Page 49: System Maintenance And Servicing

    Disregarding pilot’s error, battery failure is one of the main reasons for model crashes. For safety reasons Weatronic recommend the use of high quality battery packs which should be charged and maintained by a good quality micro processor driven charger.

  • Page 50: Lithium Polymer (Lipo) Batteries Considerations

    Long-term storage (for example, over winter) should be done between +10 and +30°C. Weatronic recommends replacing NiMH packs every 2 years as this period of time their reliability may reduce significantly and a new pack will cost a fraction of what a crash would.

  • Page 51: Data Log Monitoring And Maintenance Considerations

    8.3. Data log monitoring and maintenance considerations. Using the flight log can be an effective way of monitoring the performance of your system and a possible degradation with time. After having configured NavView as described in chapter 7.8.1. above, you will be able compare you system data.
