Nikolay Gerasimovitch Golodnikov is an Ace with seven victories over German aircraft and flew the Hurricane and P40 in battle as well as the I-16 and Aircobra. Briefly, his opinions on the Hurricane and P40 were;
Hurricane
".....It had a very thick profile and poor acceleration characteristics. At maximum speed it was somewhat faster than an I-16. But until it had attained this speed, many things could happen. It was not slow in responding to the control stick, but everything happened smoothly, in its own time. In the I-16, if you moved the stick, the airplane inverted right now. With this beast, it would roll over very slowly.
It had good lifting strength and could therefore equal the I-16 in rate of climb.
It was very good in horizontal maneuverability. If four Hurricanes established a circle, it was impossible to break out of it. No Germans could break into the circle either.
It was very poor in vertical maneuver, the thick profile. Primarily we tried to conduct battle in the horizontal and avoid the vertical plane.
The Hurricane had a short take-off run, again because of the thick wing.
In its technical and tactical characteristics the Hurricane was somewhat behind the Messerschmitt Bf-109E, primarily in the vertical. It was not inferior in the least in the horizontal. When the Bf-109F arrived, the Hurricane was well outclassed but continued to contest the skies.
The Hurricane burned rapidly and completely, like a match. The percale covering."
P40
"....the P-40 significantly outclassed the Hurricane, and it was far and away above the I-16.
Personally speaking, the P-40 could contend on an equal footing with all the types of Messerschmitts, almost to the end of 1943. If you take into consideration all the tactical and technical characteristics of the P-40, then the Tomahawk was equal to the Bf-109F and the Kittyhawk was slightly better.
Its speed and vertical and horizontal maneuver were good. It was fully competitive with enemy aircraft.
As for acceleration, the P-40 was a bit heavy, but when one had adjusted to the engine, it was normal.
When the later types Bf-109G and FW-190 appeared, the P-40 Kittyhawk became somewhat dated, but not by much. An experienced pilot could fight an equal fight with it."
