Tilt rotor stop in ACRO mode

Hello,

I am using Plane 3.9.0 on my X8 tricopter with pixhawk 2.1.

I use a configuration of 3 rotors and they all have mechanical rotation.

It works very well but I have a problem with the tilt rotor, when I go from Q mode to ACRO or FBWA, the rear motor stops pushing.

How can I set the motor tilt to work in airplane mode?

Add my config params.

Thank you!!

Try Q_TILT_MASK 11 instead of 3

(Tiltmotor 1,2 and 4 are titltable, 1+2+8=11)
