About this Plan

Vega. Free flight towline glider model.

Quote (google-translated): "BUILDING INSTRUCTIONS. The model is intended for beginner modellers and for recreational flying. It cannot be used in competitions in the A1 or A3 categories; its dimensions, or rather its area, are exactly in the middle between the models in both categories. Therefore, it has a spatial fuselage, which, in addition to its similarity to a real glider, is also more rigid than a rod fuselage. For transport reasons, the wing is split; it is - as is the horizontal tail surface (VOP) - attached to the fuselage with rubber. To limit the flight time and prevent the model from flying away in thermal weather, it is equipped with a determalizer: the VOP deflects after a specified time and puts the model into a steep descent.

The model is simple in shape and construction due to its purpose. To speed up the construction, ready-made plastic Model ribs (Set of plastic ribs, cat. No. 4130 and 4131), which can be purchased at model shops, are used. However, the ribs can also be made of balsa 1.5 to 1 mm thick.

To build. We build the individual units of the model, i.e. the fuselage, wing and tail surfaces on a work board on the drawing, over which we place a transparent foil. We connect all the parts with acetone glue, securing them with pins until the glue dries. Before assembling the respective units, we prepare all the necessary parts — we trace them onto balsa planks and cut them out precisely with a sharp pointed knife on a wooden base. In doing so, we remember that the smoother surface is on the outer surface of the model; it is best to sand the planks with fine sandpaper beforehand.

Fuselage. We attach the lower part Ti to the drawing and support it in front. Glue the side panels T2 to it from both sides (with the smoother surface on the outside), secure with pins and gradually glue the prepared head T3 (glued together from boards), partitions I4 and T10 and connect the side panels at the back. Check the perpendicularity of the side panels to the worktop with a triangle. Then glue the upper rear cover T11 and the upper front cover T12. Leave the part between the head panel T3 and the partition T4 without cover for now. Remove the fuselage from the board and work the head into a round shape, extending the upper cover to the plane of the side panels. Sand the entire fuselage until smooth and slightly round the edges - except for the part where the wing and VOP are attached. Glue the ski T13 with the tied towing hook T14 into the cutout at the bottom of the fuselage and glue the spur T15 butt-jointed. Drill holes for pins T16 and T17, insert them, but do not glue them. Cut the wing support plate T18 in the middle along its length, break it, drip glue into the break and glue the plate to the fuselage. Secure its position and shape with the finished wing, which we place on it and tie with a rubber band. Then glue the VOP support plate T19.

After the glue dries, remove the wing and VOP, remove the pins (we glue them only after the fuselage is glued), cut out a longitudinal hole for the fin S1 and glue the finished vertical tail surface and VOP support T20. Then we fasten the wing and the VOP again, support the model under the wing support plate at the center of gravity and insert and then glue such an amount of weight (preferably lead sheet) into the fuselage between the head T3 and the bulkhead T4, so that the fuselage is horizontal. We finish the upper skin, in which we make a hole for later replenishment of the weight and clean the skin.

The wing is divided; its halves are connected by two wire connectors. On the construction drawing, we pin the leading edge K1 (glued together from 2 and 3 mm thick strips) and the trailing edge K2, both already machined to the shape according to the drawing (there is a risk of damage when machining on the finished wing), the lower edge of the spar (we measure the position with a rib) and the edge..."
