One more advice: practice, practise and practise again. This is a sim (or at least close to that
) and there is a reason why pilots need several hours of training in double seater trainers before they can fly an aircraft alone.
Start flying with a forgiving aircraft like the Il-2 and be easy on the controls. No abrupt pulling/pushing. Stay away from late war fighters as they are usually difficult to fly (especially the P51 and the FW 190 are awful for beginners).
