A Standard Class sailplane which first flew in 1964, the Utu has a fixed landing wheel and a trailing-edge split spoiler/terminal-velocity brake. One surface rotates up like a spoiler and the other splits down like a flap and the resultant air deflection from the upper spoiler drives the wing down in a strong negative lift configuration.
