The Astir CS (club standard) was the first sailplane designed and serially produced by Grob. It features composite (fiberglass/resin) construction, a large wing area, a T-tail and water ballast. A Standard Class Sailplane, the large wing area gives good low speed handling characteristics. The main gear retracts. A slightly improved version, the CS-77, was introduced in 1977. The CS-77 has a different rudder profile fuselage similar to that of the Speed Astir. The Standard III followed in the early 1980’s reverting to the higher profile fuselage and with reduced empty weight and increased payload. One, flown by R.R. Harris of the U.S., won the world absolute altitude record at 14.938 m./ 49.009 ft in 1986. Specifications are given for the Standard III. ATC, except for the Standard II which is EXP.
