Parameter setting for Bicopter with Tilt Rotors

I am building a Bicopter and referring to Quadplane Setup and Operation in wiki.

Q_FRAME_CLASS I set it to 10. Is it correct for Bicopter ?

Q_FRAME_TYPE
Wiki does not have this param for Bicopter. What values should I set ?

Q_TILT_TYPE Arduplane V4.2.3 does not have this param (3 for Bicopter as indicated in wiki).

Q_TILT_MASK
What values should I set for this param ?

SERVOn_FUNCTION
Should I use TiltMotorFrontLeft/Right, or TiltMotorRearLeft/Right value?

Thank you for any help.
