May day, somebody help me please!!!

[Flanker1985]

Hi, Guys. I have just bought this game a few days ago. But I have found this game is much more complex than the previous IL-2. Back in IL-2:1946, all we need to do is watch our atitude and speed, manifold pressure, RPM and our verticle velocity. But this one is so complex that I have no idea what else I need to know in order to fly. For example my engine often end up with "water Radiator Perforated". What does that mean??? What did I do wrong?
Also my engine often have other issues as well, sometimes I can't even start up.

This is the most realistic piston engine plane simulation I have even known. And I really want to learn. Can any one please teach me how to fly it apprepriately and what gadget else do I need to watch out for??

Thanks a lot. Really appreciate if someone can help me.
