Speedy bee F405WING SERVO OUTPUT GROUP?

I have build a 4+1 VTOL.ALL ESC can be use Dshot mode.Accourding to Speedy bee F405 WING manual , ALL outputs in that group be configured and used as Dshot, rather than PWM outputs.

  • PWM 1,2 in group1
  • PWM 3,4 in group2
  • PWM 5-7 in group3
  • PWM 8-10 in group4
  • PWM 11,12 in group5 Note: PWM12 is setup for serial LED use by default, if PWM11 is used for motors or servos, you must re-assign PMW12 to a normal PWM output or nothing

So I set servo3,4 and 5-7 to DSHOT protocol,servo 3-6 was set as motor1-motor4,and the function of servo7 was set to throttle.
the motor1 to 4 works ok,but the motor of fixwing can’t spin.
does i set someting wrong?
does one group can be mix with motor and throttle?
