Building the sheet balsa chuck glider Lomir gejn tanzn!

Materials:

Fuselage: B 3; wing supports: B strips 5 x 5; V-tail supports (optional): B strips 2 x 5 or 5 x 5; bamboo dowels diameter 5 mm; wings: B 1.5; V-tail: B 1; linen band width ½ in; 2 household rubber rings; ballast: steel or lead 7.5 grams / ¼ oz.

Assembly:

Cut out balsa parts in accordance to plan (photo). Make cutouts for wing and empennage on fuselage part (photo). Sand well. Mark positions of dowels with pencil. If coloring is desired do it at this stage.

Wing:

Fix one wing half on building board with needles. Cement other half at given dihedral to it. Linen/cotton band should later be cemented on the joining areas on top and bottom (photo). Let thoroughly dry. Cement linen band around leading edge of the wing so that band forms an U around the leading edge. Let dry. Cement a short piece of linen, around 5 cm or 2 in long, in the same manner at the wing trailing edge center area. This is where wing comes in contact with rubber rings. Linen reinforced areas protect thin balsa from cracking.

Fuselage:

Strengthen nose on both sides with some extra glue. Disperse glue well and let dry. Fix fuselage on building board with needles and cement wing and V-tail supports. Let dry.

Repeat this procedure on the other fuselage side holding support strips in place with clamps or clothespins. Let dry.

Drill holes for bamboo dowels. Cement dowels in place and let dry. Visual check symmetry!

Empennage:

Cement V-tail halves one to the other observing the given dihedral angle. A self made template from balsa will turn out helpful for this step. Reinforce joining area with linen band.

Final Assembly:

Set wing on wing support and assure that absolute symmetry is obtained. If not sand down a little balsa on one of the wing supports. Same procedure with empennage. Visual check better twice than once to obtain best possible symmetry.

Now use rubber rings to fix wing and empennage on fuselage. Start test flying. Use small piece of lead or scrap metal as ballast.

Remember correct center of gravity (CG) is essential for successful flights.
