Introduction
The CHIP is an ideal beginner’s hotline model, which offers maximum flying pleasure for minimum building effort. The model is highly pre-fabricated, but the procedures described in the following instructions must be carried out with the greatest care to ensure that the model flies safely and well. The aircraft’s all-up weight must not exceed 600 g.

Building instructions
Please read right through these building instructions before you start construction, to ensure that you have a clear understanding of the sequence of operations required. Lay out all the components, tools and adhesives for each stage before you start work, and prepare the model parts as described in the building instructions. When assembling the components always work on a clean, smooth surface, or cover the workbench with a layer of soft foam. Use cyano-acrylate and activator as adhesive. We recommend that you apply the glue to one joint surface, and spray activator on the mating surface. Take particular care to avoid adhesive running onto your hands or the model’s surface; immediately wipe off any excess glue using paper towel.
Caution: cyano-acrylate must never come into contact with body parts. Take particular care to avoid it getting in your eyes; we therefore recommend that you wear goggles when handling cyano. Store the adhesive well out of the reach of children. For safety reasons we recommend that you only use the adhesive stated above.

Fuselage and tail
Use a balsa knife to continue the channel for the reinforcement (2) right through to the end of the fuselage. Tip: use the balsa knife just to cut the side slits, then push out the scrap SOLIDPOR foam using the strip of spruce (2). Fit the spruce strip and ensure that it rests completely on the bottom of the fuselage. This is important, otherwise it will not be possible to push the fin (4) fully into place.
Locate the lug at the front face of the fuselage produced by the moulding process. Remove this to provide clearance for the power leads of the INLINE 400 electric motor.

Cut a 10 x 6 mm opening at the bottom of the fuselage for the servo leads.
Push the strip of spruce (2) through to complete the opening.
Glue the fuselage reinforcement (2) exactly central in the fuselage (1), and press it into place. Check carefully that the fuselage is not distorted when you do this.
Roughen the surface of the captive nut (3) using abrasive paper, then glue it in place using plenty of adhesive. When the glue has set hard, fit the retaining screw (12) in the nut and pull on it to check that the joint is strong enough. Use the balsa knife to cut the elevator snake outer sleeve (6) to a length of 440 mm, and press it into place as shown in the picture. Glue the elevator snake sleeve (6) to the side of the fuselage reinforcement (2) at the front.

Cut off a 2 mm wide wedge from the fin (4), sand the joint surface of the rudder snake outer sleeve (5) and glue it in place. Take care to glue the snake sleeve inside its channel only. Don’t glue the horn (9) in place at this stage.
Glue the snake sleeve (5) to the underside of the fin at the front. Ensure that it ends flush with the fin; it must not overlap the fuselage reinforcement (2) later, as this would make it impossible to insert the fin (4) completely. Temporarily slide the prepared fin into the fuselage; if there is a gap between the fuselage and the fin, squeeze the fuselage sides together at the top.
The fin can now be glued in place. Caution: don’t use activator for this joint,
otherwise the parts will stick together before you have a chance to position them correctly.
Apply cyano to the spruce strip (2) and the inside of the fuselage, then slide the fin briskly into place. Ensure that it ends flush with the top of the fuselage, and makes contact at the tail end.
