If you're carefull about energy, and don't make it a pure TnB fight, you can actually turn with quite a lot of aircraft. It can also do a climbing turn defense better than most I feel.
So if you dont turn it, it can turn

Jager, if you dont give up your energy, thats not a turnfight but an energy-fight. And yes, any aircraft is good if you come with E.
Its not a good turnfighter - a K4 can turn inside it. Wouldnt be that bad, but the flaps are ineffective. Still, baba's 4hog had to use his CV ack last time i upped a 205. True, it wasnt the plane, it was him being... not too tricky.
