RE: F-20 have washout?
Well, take a Warbird of any kind. Stall it and its over. Planes like Edges, Extras and that line can stall but it takes more effort to make them stall. I watch these guys bring those extras and such in on landings low and slow and plop it down. You try that trick on a warbird or a prop jet and its going to plop down right on its back!
I am not saying come in and land full speed but you cannot land them like a trainer or a stick and need a bit of throttle while landing. No coasting on in.
