I-153: cheap or not?

The I-153 has a great roll rate, so the pilot will just roll it on its back and then follow you down. That tactic will get you some breathing space though, so its worth trying if you need to escape from an I-153 on your tail.

Ahh sorry - I couldn't see how lift was factored in, but I'm conditioned to think of velocity as a 2D vector, but obviously here it is 3D. So includes lift.

That's what I said. Monoplanes can't do that cause their corner speed is higher.
They can't turn without descending at airspeeds below around 200kph, not at their maximum turn rate at least.
