Fayrwerks,
Like I said, get a flight sim. There is no added cost if you crash on the sim. You are going to get do's and dont's about expo. I fly Warbirds, P-51's Corsairs. Spitfires, etc... I want my aircraft to do exactly what I tell it to do when I tell it to. Try landing a Warbird with a bunch of Expo in the elevator or rudder and take a sweat check as the beads roll off your face. No thanks.
