Tricopter VTOL plane

I want to build a tricopter style VTOL plane(wings and a tail), with 2 motors on the leading edge of the wing and one motor behind the wing, Y configuration. I would like the 2 motors on the leading edge of the wing to be able to move/tilt for VTOL and straight flight, the 3rd motor can stay in fixed position facing upwards for VTOL and only powers up during VTOL.
I have been building and flying planes for quiet some time now and this is a totally new venture for me. I am not very well versed when it comes to drones and its electronics. After doing some research I found out that Pixhawk 2.4.8 with GPS is available in one of my local hobby stores.
I would be grateful if anyone could guide me if it’s possible to do so with pixhawk 2.4.8.
I’ll be using turnigy tgyi6 transmitter with Turnigy TGY-iA6B V2 6CH 2.4G AFHDS 2A Telemetry Receiver S-Bus.
Also apart from the motors, escs, lipo and servos what other electronics will i be needing for this project.
If such a project has been done earlier (which i am sure of) then please guide me in that direction.
Looking forward to suggestions and support from you all.

Anyone here to guide me?
