It does turn the fastest. Needs an onboard computer to fly. Dihedral angle range that that stops roll from occurring. High stability This wing type turns slowly (like a bus) and has an increased amount of drag This wing type that self corrects roll & yaw by having more lift with lower wing to bring the lower wing level with the upper wing. Generate most of the lift on a glider This wing type has a low amount of stability. It turns the second most quickly. Dihedral angle range that causes back-and-forth, but will not roll. This wing shape has low efficiency
