Comment:
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. |
