Compared to the Il-2, the new Il-10 had really good flight characteristics — the ground speed at nominal engine operation increased from 389 to 507 km/h. Climbing speed and maneuverability increased: all this was possible due to the use of all-metal construction, a new thinner and faster wing profile and, of course, a new Mikulin AM-42 engine, which was a further development of the AM-38 engine. The design of the landing gear was changed so that it didn’t protrude from the wing when retracted, and the radiator intakes were moved to the wing root.
