About this Plan

SZD 30 Pirat. Radio control stand-off scale sailplane model. Wingspan 109 in, wing area 701 sq in.

Quote: "If you have been wanting to give a scale sailplane a try, but were concerned about lengthy construction and performance, then maybe this is the plane you've been waiting for. SZD-30 Pirat, by Mike Hollison.

The lnstytut Szybownictwa (SZD) was responsible for the design and development of all gliders and sailplanes in Poland between 1947 and 1980. Over 4000 aircraft of more than 100 different types were produced and exported all over the world - a tribute to the excellence of the Polish sailplane industry and its flying machines.

The SZD-30 Pirat first flew in 1966, production started in 1967, and by the end of 1976 over 700 had been built, illustrating both the success and popularity of this design.

The Pirat is a multi-purpose sailplane designed for both training and competition flying, and is capable of basic aerobatics. Being of mainly wood construction, the full size Pirat lends itself very well to conventional balsa and ply modeling, and results in a light and maneuverable R/C sailplane well within the building skills of the experienced modeler.

Construction:
(1) Start with the fuselage by cutting all the formers to shape, drilling them for pushrods and/or wing mount as indicated, and halving formers F-2 to F-8.
(2) Cut the balsa spine and keel to length, lay them over the side view on the plan and glue F-4 through F-7 in place.
(3) Position former F-3 over the plan and connect to the rest of the fuselage with 1/4 sq balsa longcrons.
(4) Next, add F-2 and join to F-3 with the lower 1/4 sq longeron.
(5) Glue former F-8 in place, and proceed to sheet the fuselage with WV balsa fore and aft from F-3 to F-8, and from the spine down to the bottom longeron. The bottom of the fuselage between F-4 and F-8 is sheeted after the elevator, rudder, and radio antenna lead-outs have been installed. Remove the fuselage assembly from the board.
(6) Epoxy the remaining halves of formers F-2 through F-7 to the fuselage shell, adding F-3a to F-3, and the 1/4 in ply... "
