By the looks of it, your falken doesn't have any engines so maybe that's why it isn't flying? (Of course you have engines, this is just a way of saying if I can have a BP of it i could help more)

Ok, if it still flips out of control after a while if flying, try to make the thrust output make a straight line the cuts the center of mass and thrust output (individualy for both sides i would check the BP but I need my sleep)
Could you send a picture of the plane with the engines? I don't know how do you put them, but the best way is to clip all the engines ( make sure to disable their heat) the closest possible from the center of mass and add RCS to prevent it to flip
