Tornao's relative lack of controllability in AIR - Cannot get consistent flight

So running into the issue with the tornado. I like the plane, and if I can resolve this one issue it would be my favourite in Sim second to the harrier. The problem being that I cannot get it to fly level, trimming it doesn’t do anything, using SAS seems to want to throw it into the ground. Is there anything that can be done to resolve this or is it yet another case of Britain getting shafted because Britain?
