Experiments with different types of tail configurations on tip launch gliders with slow motion clips showing what happens right after launch when the glider is subject to severe yaw. A conventional Y tail will twist so that half the stab becomes a rudder which helps yaw correction. However the Y tail also causes a pitch down moment which is especially bad when combined with an under cambered wing. Flipping the Y tail 180 degree proves this point as glider will pitch up significantly but there are other complications. X tail configurations combined with very stiff tail booms show promise as the launch is more straight and smooth which should eventually translate into less energy lost and more height.
