can you confirm does Speedy Bee F4 V3 support DShot?

MOT_BAT_VOLT_MAX,24.6 (6x4.2)
MOT_BAT_VOLT_MIN,16.8 (6x3.2 ??)
MOT_PWM_MAX,2000
MOT_PWM_MIN,1000
MOT_PWM_TYPE,5

double-check your motor order too.

FRAME_CLASS,1
FRAME_TYPE,1
SERVO1_FUNCTION,36
SERVO2_FUNCTION,33
SERVO3_FUNCTION,34
SERVO4_FUNCTION,35

follow the configurator approach, understand what you bring to the Speedy Bee, check your drone CG, and do this first flight test.
