Beginners questions

[Strax]

Hello,
I've been playing IL2 for many a year and have decided to take the plunge with COD. I'm only on the training flights at the moment and have come across a problem when starting my engine. I hit "I" the engine cranks over and then dies. What am I doing wrong?

Also, is it possible to "look" using the mouse as it is in IL2?

I'm sure I'll have plenty more questions for you soon enough.
Thanks in anticipation.
