Can't throttle up beyond arming

Hi Hosein, thanks, your reply made me think about the calibration process, I went back to the MP, defined a BLHeli pass through, changed to Dshot150 and two things came up:

  1. I installed BLHeli suit, managed to connect but the suit shows all ESC’s have no data
  2. Suddenly seems like I can throttle up.

I will re-check with props installed and see if I can takeoff and fly.
Will update…
