The SucceX-D F7 V2.1 is designed to work seamlessly with DJI’s new HD FPV system, connector to allow direct connection of a DJI Air unit with the included wire harness. In addition, iFlight added the popular and reliable USB Type-C as used in the DJI module.


- Universal USB Type C connector instead of micro USB

- Plug-and-Play. No need to solder tiny wires.)

- Supports BLHeli pass-through for easy ESC upgrade and configuration.

- Designed to support DJI Digital FPV.

TwinG Gyro Setup in Betaflight CLi:

  • Betaflight default setting is "gyro_to_use = both" (GYRO FUSION is active, the dynamic fusion and averaging)
  • To check the current setting, type "get gyro" and look for "gyro_to_use = xxx" (xxx being: "first" or "second" for single gyro and "both" for dual gyro)
  • FC can also operate in single gyro mode, using either gyro
  • To change settings, type "set gyro_to_use = xxx" (xxx being: "first" or "second" for single gyro and "both" for dual gyro)
  • Type "save" to activate your setting
  • to get the most reliable performance or encounter noise, oscillation and bent props: Please use the default setting "both". 
  • For single gyro use, please use the debugging options to find and tune for the cleaner gyro, but lose the dynamic fusion and averaging. 
  • BF offers the following dual gyro debug options: dual_gyro_raw, dual_gyro, dual_gyro_diff, dual_gyro_combined
  • BlackboxLog explorer graph: dual_gyro_raw Debugging = [0] Roll Gyro1, [2] Roll Gyro2, [3] Pitch Gyro2
  • the displayed graph will show the Gyro_Raw reading (no filters applied), both gyros can be compared

TR Tip: Take extra care when using the provided wire harness to connect a 4in1 esc to your FC. To avoid damaging the boards, before powering up, always double check that the wires are correctly connect to the respective pins on the boards, especially the positive and negative connection  powering  the FC.
