He hasn't flown one so how can he.
Very true, I haven't flown one, and can't possibly tell you how the real one flys. But, the Lightning is a swept wing jet and should, at a minimum, have certain swept wing jet qualities. As I said before, the model does fly well and pleasantly enough, it just won't bite you in the butt like a swept wing jet will. Fighters are typically known to bite you in the butt even harder.
