+### TailSitter support
+TailSitter is supported by add a 90deg offset to the board alignment. Set the board aliment normally in the mixer_profile for FW mode(`set platform_type = AIRPLANE`), The motor trust axis should be same direction as the airplane nose. Then, in the mixer_profile for takeoff and landing `set platform_type = TAILSITTER`. The `TAILSITTER` platform type is same as `MULTIROTOR` platform type, expect for a 90 deg board alignment offset. In `TAILSITTER` mixer_profile, when motor trust/airplane nose is pointing to the sky, 'airplane bottom'/'multi rotor front' should facing forward in model preview. Set the motor/servo mixer according to multirotor orientation, Model should roll around geography's longitudinal axis, the roll axis of `TAILSITTER` will be yaw axis of `AIRPLANE`. In addition, When `MIXER TRANSITION` input is activated, a 45deg offset will be add to the target angle for angle mode.

 ## Happy flying
 
 Remember that this is currently an emerging capability:
