The Sagitta (Arrow) was the first and last single seat standard class design from Holland. Designed by Piet Alsema the Sagitta first flew in 1960, after three years of planning. It has an all-wood fuselage and wooden wings with fabric cover. The Sagitta was the first "Standard Class" glider design to appear from the Netherlands. It was a modern high performance design with features like automatic connecting control surfaces on assembly and a backward sliding canopy that can be fixed open in flight at several positions. Piet Alsema used his three years planning and research before the first prototype flew on the 4th of July 1960. Even today the glider looks slick with its slender all-wood fuselage with raked fin and rudder, long pointed nose and sliding blown canopy which provides excellent all-round visibility. The two piece wing has a single spar made of spruce and about 25% of the wing is covered with fabric. The ailerons are plain wood and the uniquely constructed airbrakes open both from the upper and lower wing surfaces. The fuselage is of a relatively light construction, while the wings with their extremely strong spruce spars and wooden ailerons are quite heavy constructed. This model with its fiberglass fuselage and its fiberglass reinforced, balsa sheeted foam wings can handle full aerobatic pattern. The careful use of composites with competition balsa, creates a good light structure that will hold its shape for a long time. One of the unique features of this ARF is its wing construction. The wing is foam core balsa sheeted with both fiberglass and carbon fiber reinforcing. The leading edge is actually fiberglass. This gives the Sagitta performance characteristics similar to a fully molded wing while still remaining very light and relatively inexpensive. The synergy of low weight and strong structure is very unusual in a production sailplane and can only be achieved with careful attention to design and construction. This model is considered one of the best values on the market today.

With its fiberglass fuselage and its fiberglass reinforced, balsa sheeted foam wings the Alsema Sagitta can handle full aerobatic routine. The careful use of composites with competition balsa, creates a good light structure that will hold its shape for a long time.
