Esc desync? No it's the MIN THROTTLE!

I was experimenting this strange attitude during my Realacc TC-R220 tuning flights.
I initially think was an esc desync problem or a motor failure. After reading lot of articles online, i fixed it by raising my MIN_THROTTLE from 1018 to 1030 in Betaflight. Hope it helps...Happy Flying!
