sd-1 minisport Airplanes - Construction
The fuselage is comprised of sitka spruce trusses reinforced with carbon fiber and carbon rods, covered with thin plywood. The inside width of the cockpit is 21.3” (54 cm) in the standard version, with expansion of the pilot compartment possible with the XL version. The back of the pilot seat is inclined slightly for comfort and is removable to allow access to the baggage compartment located behind the seat. The cabin hood is made of composite with a polycarbonate windshield.
Wing assembly consists of a composite main spar with carbon caps to which the ribs of extruded polystyrene are glued. This skeleton is covered with thin plywood and wing tips of extruded polystyrene with fiberglass lay-up are attached. The wings are connected to the fuselage by two main and two auxiliary pins. The flaperons are connected to the controls by a control pin.
The construction of the horizontal tail is similar to that of the wings. The tail is completely moveable, has an anti-servo tab, and is statically balanced. Spring trimming is under the pilot seat. The fin has a main composite spar with carbon caps and a tail hinge. Tail attachment consists of control and tab rods, and a pin. The horizontal tail and flaperons are controlled by pushrods and bellcranks. The flaperon mixer is under the pilot seat. The rudder is controlled by 2mm cables.
Any engine from 24 to 50 HP can be used in the sd-1 minisport. Maximum engine weight is 93 lbs (42 kg). The integral fuel tank is made of fiberglass and PVC foam and is located behind the firewall. The electrical system is battery-operated and will accept a 12 V outlet for accessories like GPS. The instrument panel includes an airspeed indicator, altimeter, compass, vario, and slip indicator. There is also space for a COM transceiver and TPD with a diameter of 57mm. The Com antenna is built into the airframe.
The SD-2 SportMaster is a Kit airplane with one of the best price / performance / payload ratio on
the market. A clever mix of construction materials (wood + carbon composites) provides low
empty weight and high performance values. The cockpit is standardly equipped with adjustable
pedals and is comfortable even for 2 m tall pilots. The wing loading up to 52,5 kg/sqm allows high
cruise speed in rough air conditions. A short takeoff and landing distance is possible thanks to
the advanced slotted flap used. Available in 51% kit format.
