- -1.0<throttle<=0.0 : motor stop, default value 0, set to -1 to use a place holder for subsequent motor rules
- -2.0<throttle<-1.0 : spin regardless of throttle position at speed `abs(throttle)-1` when Mixer Transition is activated.

Airmode type should be set to "STICK_CENTER". Airmode type must NOT be set to "THROTTLE_THRESHOLD". If set to throttle threshold the (-) motor will spin till throttle threshold is passed.

Example: This will spin motor number 5 (counting from 1) at 20%, in transition mode only, to gain speed for a "4 rotor 1 pusher" setup:

## Motor 'Transition Mixing': Dedicated forward motor configuration
In motor mixer set:
- -2.0 < throttle < -1.0: The motor will spin regardless of the radio's throttle position at a speed of `abs(throttle) - 1` multiplied by throttle range only when Mixer Transition is activated.

- Airmode type should be set to "STICK_CENTER". Airmode type must NOT be set to "THROTTLE_THRESHOLD". If set to throttle threshold the (-) motor will spin till throttle threshold is passed.

2. In addition to 1. Add a little yaw mixing(about 0.2) in tilt motors.
- There will be a time window that tilting motors is providing up lift but rear motor isn't. Result in a sudden pitch raise on the entering of the mode. Use the max speed or faster speed in tiling servo to reduce the time window. OR lower the throttle on the entering of the FW mode to mitigate the effect.
