This wing type has a low amount of stability. It turns the second most quickly. Only item on a flat winged glider that will stop roll & yaw Dihedral angle range that causes back-and-forth, but will not roll. This wing shape has low efficiency Force that must be overcome to fly upwards This wing type turns slowly (like a bus) and has an increased amount of drag Dihedral angle range that that stops roll from occurring. High stability Generate most of the lift on a glider This wing type is the least stable of the wing designs. It does turn the fastest. Needs an onboard computer to fly.
