The I-16 was certainly maneuverable, but with a 19 foot long fuselage and 20 foot wingspan, there's not a whole lot to move around. Couple that with the 1,000 HP motor on the front and it is a real unstable pony. Turn too quickly, it will spin. But from what I have heard, if you can fly an I-16, you can fly anything.
Here is one of about a half a dozen survivors when it visited our museum.
It took a hearty Russian to fly in an open cockpit in those Russian winters! BRRR!
