text_A: Initial service experience revealed that the ShKAS machine guns had a tendency to jam. This was the result of the guns being installed in the wings upside-down to facilitate the fit. The problem was addressed in later modifications. Evaluations from pilots confirmed the experience with prototypes. Controls were light and very sensitive, abrupt maneuvers resulted in spins, and spin behavior was excellent. An aileron roll could be performed in under 1.5 seconds (roll rate over 240 ;degrees/second). The machine guns were fired via a cable and the required effort, coupled with sensitive controls, made precision aiming difficult. The unlikely rear weight bias made the I-16 difficult to handle on unprepared airfields because the aircraft was rather likely to flip over the nose, especially if the front wheels dug in.
text_B: Is an aerospace engineer likely to be surprised if you tell them about the rear weight bias of an I-16?
YES.
