I'm aching over this. I'm still learning about correct tuning methods and the ties between kv and desyncs occurring so bare with me please.

Just built this quad:

Mamba DJI F722 MK2/50a BLS stack (running bluejay)
Emax eco II 1900kv motors
6s
BF 4.3 stock tune
DSHOT600, 8k/8k, bidirectional dshot enabled (default filter settings, still need to learn how to tune)

When I first took it out I could arm and hover just fine. The second I punched out a little (not a full punch) it fell out of the sky. I did some research and realized it was probably a desync (made the high pitch noise as well). I changed some esc settings and upped the idle value to 7%. Now it sort of flips out a little when I punch out but doesn't fall. Here's bblog and current esc settings. I appreciate any help. I know this is not a new problem but I'm stuck. Thank you for reading this.

Did you set the ESC's to 96Khz? That could be a reason for the desync on your setup.
