SITL for quadplane

Hey guys I’ve been trying to simulate my V-tail Tiltrotor-Quadplane using SITL
I am facing the several issues

  1. Motor arrangement - where can I see which 2 motors are tilted. I can see that it load servo12 and servo13 with param as tiltmotor.
  2. During Fixed wing flight all 4 motors are working, but in real life only 2 front motors should be working.
  3. When I shift to MANUAL or ACRO mode the motors reach maximum PWM rather than stopping.

Idk what exactly is wrong. Can someone help me with the right parameter set that can be used for this. I am using a freeman VTOL.
Thanks in advance.
