Welcome aboard this deathtra- I mean airliner.

Its effectively a larger QC-12.2 series airliner, but less safe.
Why? There are multiple problems with the elevators:
1: Sometimes, it can just cause the aircraft to pitch down and fall out of the sky
2: Sometimes, it does the opposite and causes a stall

The cockpit is a complete mess as well, with instruments put in random places and the copilot not having any flight controls.
And the pilot in command can't actually see anything.

VTOl slider: Flap control
Activation groups 1-4: (De)Activates engines 1-4

Just don't break the plane, comrade.

Protip:
Use the rudder, it helps you to roll since the ailerons are next to useless.

It can also cause the plane to fall out of the sky as well.
