SucceX F7 V2.1 TwinG // GY.RO FUSION is the NEXT-GEN flight controller you need for your next build. This FC is ready for anything with 5 uarts, 8 motor outputs, 32Mb blackbox and a powerful F7 processor to run it all.

With its clean intuitive layout, the SucceX F7  TwinG V2.1 makes installation a breeze with a 4 pin connector for your VTX and an 8 pin connector that allows simple plug and play connection with your 4in1 ESC.

But the real magic of this flight controller lies in its TWIN GY.RO configuration.

The TwinG uses two identical gy.ros oriented side by side with one offset 90 degrees from the other. Betaflight uses GY.RO FUSION to blend and average the information from both gy.ros to send a much cleaner signal to the PID loop controller! Less noise and fewer oscillations across the throttle band without adding any delay! Betaflight software filters can be lowered in most cases as well, which brings a significant decrease in delay.

With plenty of processing power and uarts, this is the perfect flight controller for long-range GPS builds. And the TwinG configuration makes it the perfect Fc for builds like macro quads, cinematic filming rigs and x-class racers that are a bit trickier to tune.

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.
