Domino (oz10410)

About this Plan

Multiplex Domino. Radio control sailplane. Wingspan 2300mm. Uses sheeted foam wing.

Quote: "The Glider 'Domino' is designed for the beginner or advanced model pilot. The airfoil combination and wing geometry of the Multiplex styro-foam wings endow the model with a wide speed range, excellent flight performance, and docile handling. Kit contents: Sheeted Multiplex styro-foam (cored) wings (with factory installed balsa skins), die-cut balsa and plywood parts, clear plastic canopy, hardware for radio installation, transfers (decals), detailed plan (three sheets), and extensively illustrated building instructions."

Note this plan file has 2 sheets. Sheet 2 titled 'Elektro-Domino' shows optional powered-glider configuration, using electric Permax 600 BB motor with gearbox and an extension shaft.

Quote: "Building instructions for the Domino: Introduction: The Domino has been designed in such a way that the beginner to modelling can complete the model without any outside help.

The model's robust construction makes it capable of absorbing considerable abuse. The two-part ready-made wings are attached of the fuselage by the time-honoured method of rubber bands, which allow the wings to fly off in a hard landing. The tailplane is screwed to the fuselage, as it does not usually need to be removed for transport, but is still detachable tor repairs and trim changes.

The airfoil selection and wing planform give the model docile flying characteristics without sacrificing performance.

The airfoil combination and wing geometry endow the model with a wide speed range, excellent flight performance and docile handling.

Tools: A few tools are absolutely essential if the model is to be completed successfully: 2 and 1,5 mm a drills, a sharp balsa knife, glasspaper grades 60, 120, 240 and 400 (the grade is printed on the reserse of the glass-paper), combination pliers, glass-headed pins, glues (see the section entitled Adhesives), a flat building board at least 1.20 m. long, a roll of adhesive tape and a sanding block.

The sanding block can be home-made. Find a wooden block about 2 cm. thick, 7 cm. wide and 15 cm. long. Stick coarse glasspaper on one surface, and fine glasspaper on the other. We recommend double-sided adhesive tape (Order No. 683116) for fixing the glasspaper, so that worn-out glasspaper can be easily removed and replaced with new. Taking the trouble to make up a sanding block is an important step in making a success of building the model, e.g. for sanding surfaces flat, or for tapering or contouring components to a particular shape, such as the wing leading edge and fuselage noseblock. You will find your sanding block absolutely indispensable.

Adhesives: You will need several different glues for this model:

White glue: This adhesive is still one of the best and most economical glues for modelling use. if can be thinned down with water, and can also be applied by paintbrush without difficulty. It takes a fairly long time to dry. We recommend white glue if you are a modeller who is as yet inexperienced in the use of glues.

Two-part glues:These adhesives produce joints of very high strength. They must be used in places where high loads are applied and the gluing area is small. Be sure to use only epoxy resins. They include fast-setting and slow-setting types. The 5-minute variety, such as 'Devcon', sets reasonably hard in enly five minutes. If you find this working period too short, you should use one of the slower-setting types. Always follow the manufacturers' instructions.

Instant glue: This is an ultra-fast setting adhesive of the cyano-acrylate type, sold under such names as Zap, Hot Stuff etc. The setting action is activated by moisture, either in the air or in the parts being glued (wood contains a lot of moisture). The greater the area of the glue which the moisture can reach, the faster the glue sets. For this reason, you should riot apply the glue thickly, otherwise the setting time will be retarded. Human tissues also contain a lot of moisture, and you will find that instant glue stricks human skin very effectively, and can for example, glue your finger tips together very quickly. It is particularly dangerous to allow drops of this glue to spray into your eyes. Always use the greatest care when handling these materials.

High-viscosity instant glue: Most instant glues have a thicker variant. These are more suitable for use with wood, and they generally take a little longer to set, typically 1- 2 minutes. It you apply a great deal of the adhesive, the setting time may be even longer. When using high-viscosity instant glues, take the same care as when using ordinary Instant types.

Fuselage: Fix the fuselage drawing down on the building board, using strips of tape. Cover the plan with transparent plastic film, so that the wooden parts do not stick to the plan when the fuselage is assembled.

To make one fuselage side, join the front fuselage side component 1 and the rear fuselage side 2 over the building board, and check for an accurate fit. Remove any irregularities at the joint line between parts 1 and 2 with glasspaper. When satisfied, stick parts 1 and 2 together directly over the fuselage side elevation. Pin the parts down on the building board until the glue has set, so that they cannot shift. It is a good idea to apply sellotape along the joint line while the glue is setting as this helps to obtain a neat joint.

When the glue has set, the fuselage doubler 3 can be glued to the inside of the fuselage side. Repeat the procedure for the second fuselage side, but take care not to produce two right-hand or two left-hand fuselage sides by mistake. Lay the fuselage sides on the building board with their outside faces down, so that the inside faces are exposed. Leave them like this when fitting the doublers, and it is virtually impossible to build two identical fuselage sides (figurelOpage 2).

The corner fillts 4 and 5 are added next. Take care to produce a sound joint where parts 4 and 5 meet the fuselage doubler 3..."
