RE: Toe-in or toe-out on a warbird?
A lot does depend on the geometry of the gear. My 1/4 scale cub likes a little toe-out and negative camber as it sits static, but what actually happens when the tail lifts up is the main gear flexes, the camber changes, and the toe-out actually "dissappears". My P-51 is just the opposite, it likes a little toe-in because when the main gear is under load, they flex outward almost to the point of toe-out.
