Cypher/Telemetry

Available Telemetry Settings (Optional)

• Telemetry can be very useful for the FV-31 Cypher. You can get the most out of your battery by:
  • Monitoring the flight pack voltage and set voltage alerts
    • One way (preferred by most Flex Pilots) is to set a flight pack voltage alarm of approximately 10.2V
      • Program transmitter to alarm WHILE the voltage is below that voltage, and to not alarm if the voltage recovers higher than the threshold.
      • While flying, the alarm may sound at times under high loads. Monitor this, but keep flying.
      • If the alarm is on during steady hover, steady forward flight, or more than 30% of the time, land as soon as possible!
    • An alternate way is to set a lower flight pack voltage alert (9.1V for example) and plan to land the first time it is hit.
      • This way may be less reliable due to high momentary loads.
      • May trigger early with 'weaker' battery packs.
  • Calibrate and monitor you flight pack capacity used and set capacity alerts.
    • Best if you fly all packs of the same or very similar size
    • Set a transmitter alarm once a specified capacity is reached.

NOTE: The user should always make conservative first flight with a timer, and be conservative. Monitor the 're-charge' capacity of the packs, and the telemetry indications and fine tune their best use based on their preferences.

Spektrum Telemetry

• These instructions supplement the non-telemetry setup instructions in the Cypher manual.
• Easy to setup (really just the third pin plug and telemetry slider in configurator) and provides the following Telemetry Data:
  • Provided by Rx:
    • Fades (frames lost by individual sub-Rx)
    • Frames (frames of data lost buy all combined Rx)
    • Holds (Failsafe caused buy more than 40 continuous Frame losses)
    • Some may provide Rx bus (BEC) voltage, SPM4649T appears to not provide it
  • Provided by Betaflight/FLEXF3:
    • Main Battery Pack (Main 3S) Voltage
      

      Telemetry 3-pin Connection
    • Virtual (estimated) Current
    • Virtual (estimated) Capacity used (fuel totalizer)
• Choose a telemetry capable receiver such as the SPM4649T (Preferred) or AR8010T
• Bind the receiver to the transmitter
• Connect to FLEXF3 using the first 3 pins (-,+,signal). (Use 3-male to 3-mail pin cable if required for AR8010T style receivers)
• Use your configuration tool to: (hit the pages 'Save' button before leavng each page)
  

  Set Telemetry Slider and Save
  • On Configuration page
    • Make sure Receiver Mode is set to a serial based receiver.
    • Make sure Serial Receiver Provider is set to SPEKTRUM2040/SRXL
    • Now in Other Features, set the TELEMETRY slider to ON.
  • On the Receiver page, make sure your Channel Map is set to TAER1234 (SPEKTRUM)
• You should now have Telemetry, and you can use your transmitters instructions and settings to display and alarm as desired.

Futaba Telemetry

• These instructions supplement the non-telemetry setup instructions in the Cypher manual.
• Only Telemetry provided by the Rx is available. Receivers are available that can sample Main Flight Pack Voltage.
• Betaflight/FLEXF3 Data not available, so no Betaflight settings are made.
• To connect the Receiver's telemetry to the Cypher's flight pack voltage tap:
  • Choose an S.Bus capable receiver (T-FHSS, FASSTest) that provides Telemetry and has a Voltage port (XXX, R7008SB FASSTest)
  • "Y" or "Split" the small cable that provides Voltage Data to the FLEXF3. Install the Futaba compatible Voltage Cable/Plug to the voltage cable. (check polarity carefully!)
  • Plug the voltage cable into the receiver
  • Follow the Futaba instruction to configure the Futaba equipment to display/alert with telemetry

Jeti Telemetry

• These instructions supplement the non-telemetry setup instructions in the Cypher manual.
• Powerful, but requires custom made cable.
  • Provided by Rx:
    • Radio Signal Data
    • Receiver bus voltage (BEC)
  • Provided by Betaflight/FLEXF3:
    • Main Battery Pack (Main 3S) Voltage
    • Virtual (estimated) Current
    • Virtual (estimated) Capacity used (fuel totalizer)
    • Horizon Angle in Pitch and Roll
      

      Jeti Telemetry Cable Detail
• Choose a telemetry capable receiver such as the EX R3
• Bind the receiver to the transmitter
• Fabricate the Custom 3-pin to 4-pin male -to- male cable. (You can use the supplied two cables for parts)
  

  Jeti Telemetry Cable Photo
  • Remove insulation from the middle of the 'signal' wire.
  • 'Y' the wire and install a 2.2k Ohm resistor as shown in image at right.
  • Insulate with heat shrink tubing.
• Connect to FLEXF3 using the first 3 pins (-,+,signal) at the Rx's EX Bus Port and 4-pins at the FLEXF3 (-,+,Rx,Tx)
• Use your configuration tool to: (hit the pages 'Save' button before leaving each page)
  

  Set Telemetry Slider and Save
  • On Configuration page
    • Make sure Receiver Mode is set to a serial based receiver.
    • Now set the Serial Receiver Provider to JETIEXBUS
    • Now in Other Features, set the TELEMETRY slider to ON.
  • On the Receiver page, make sure your Channel Map is set to TAER1234 (SPEKTRUM)
• You should now have Telemetry, and you can use your transmitters instructions and settings to display and alarm as desired.
