VTOL feature supported FC

I am a complete Noob never build a Rc plane.
Hey guys i am building my final year project (Dual rotor vtol plane ) and i am confused which FC should I use .(I have already purchased APM 2.8 but later found out it doesn’t support VTOL ). Please suggest me a FC (no pixhawk cube to expensive)which is cheap and can provide VTOL function and firmware in mission planner
