You need two questions in your survey, Beetle, since you're actually trying to measure two dimensions rather than one. The first concerns flight model fidelity and how important players consider it, and the second one centers around realism in gameplay.
As it stands, you have coupled attitudes toward gameplay and flight model dynamics together when they probably don't go hand-in-hand. Expect either inaccurate results or people not answering because you don't present a choice that fits with what they believe.
