The C.205 is a great plane, but you have to learn it's strengths and weaknesses. Outclimb, and out turn a lot of others, lots of cannons. It is not a speed demon, so do not try to outrun a lot of planes.
It is great for base defense, as well as bomber defense. What it is not, it is not a turn fighter, nor is it a slow speed fighter. It is a good mid altitude, mid speed fighter.
