Manual zz. Check also that the wing is correctly located and firmly secured on the fuselage before each flight. When the model is switched on, ready to fly, take care not to touch the propeller. Keep well clear of the propeller disc too, and ask spectators to stay back. Allow the motor to cool down after each flight. You can check this by carefully touching the motor case with your finger. The temperature is correct when you can hold your finger on the case without any problem.

On hot days this may take up to 15 minutes. MULTIPLEX model kits are subject to constant quality checks throughout the production process, and we hope that you are satisfied with the contents of your kit.

However, we would ask you to check all the parts before you start construction using the Parts List as a guide , as we cannot exchange components which you have already worked on. If you find a part is not acceptable for any reason, please take it back to your supplier model shop , as he is your first port of call. After checking, he will send the part or the kit to our Quality Control department. Please be sure to include the purchase receipt and a brief description of the fault, otherwise we cannot process your complaint.

We are constantly working on improving our models, and for this reason we must reserve the right to change the kit contents in terms of shape or dimensions of parts, technology, materials and fittings, without prior notification. Please understand that we cannot entertain claims against us if the kit contents do not agree in every respect with the instructions and the illustrations. Radio-controlled models, and especially model aircraft, are by no means playthings.

Building and operating them safely requires a certain level of technical competence and manual skill, together with discipline and a responsible attitude at the flying field. Errors and carelessness in building and flying the model can result in serious personal injury and damage to property. Since we, as manufacturers, have no control over the construction, maintenance and operation of our products, we are obliged to take this opportunity to point out these hazards and to emphasise your personal responsibility.

Additional items required: e. Do not use styrofoam cyano. Epoxy adhesives produce what initially appears to be a sound joint, but the bond is only superficial, and the hard resin breaks away from the parts under load. White glue is entirely unsuitable.

Specification: Wingspan Overall fuselage length All-up weight min. Wing area Wing loading FAI min. RC functions mm mm g Please be sure to use cyano-acrylate glue exclusively, preferably in conjunction with cyano activator kicker.

Apply cyano glue to the mating surface, then place the parts together and immediately position them. Please be cautious when working with cyanoacrylate adhesives. Always wear protective goggles to guard against eye injuries. Keep these materials well out of the reach of children. To fit the servo output arm extensions 43 cut off the raised collar around the central hole in the original output arm, and fix the parts together using the standard retaining screw and the locating screw 49, as shown in Fig.

Carefully lay the fuselage shells down flat, and connect the pre-formed end of the steel inner rods including snake sleeves to the servo output arms.

Apply cyano to the channels for the snakes. Check once more that the fuselage shell is exactly flat straight , then glue the snake sleeve in the channel.

Installing the motor mounts Glue the two motor mounts 60 in the right and left fuselage shells using cyano. Ensure that the mounts 60 fit flush with the foam shells before you apply the glue.

Before assembling the model Please check the contents of your kit. You will find Figs. Canopy latch Glue the canopy latch clips 32 in the fuselage shells as shown in Fig. Apply thick cyano to one shell, hold the second shell against it, and check that the fuselage is straight and correctly aligned before the glue sets.

This may take up to a minute, depending on humidity. Hold the fuselage in your hands for a further two or three minutes, checking constantly that the fuselage is still straight, because the adhesive takes at least this length of time to cure. Preparing the control snakes The first step is to cut the snake outers and inners to the lengths stated below. To cut the sleeves, place them on a hard surface and roll them to and fro under a sharp balsa knife, so that they are grooved all round.

They can then simply be broken off. It is important that the parts are not twisted relative to each other. Parts 54, 56 and 52 are required for the rudder, and parts 55, 57 and 53 for the elevator.

Cut slots for the hinges 42 in the tailplane 12 and the elevator 13 using a sharp balsa knife, positioned as shown in Figs. Place the servos in the recesses and apply a drop of thick cyano or hot-melt glue to secure them. Dismantle the parts. CA 70 17 17 19 Abb. Wipe off excess glue at the pivot line. Apply cyano to both sides of the hinges as described previously, then push the elevators into final position. Wipe off excess adhesive immediately.

Gluing the tailplane to the fuselage Offer up the tailplane to the fuselage and check that it is an accurate fit, and that it can be aligned properly. Glue it in place using cyano, and align it accurately before the glue sets hard.

Preparing the fin Cut the slots for the hinges 42 in the tailplane 15 and the rudder 16 using a sharp balsa knife, as shown in Figs. Ensure that the slots are in line with each other, and are exactly central. Glue the horn 44 to the rudder, but apply the cyano to the underside only. Now cut a slot about 1. Apply cyano to both sides of the hinges as described previously, then push the rudder into final position. Glue in rudder fin Fig.

Apply a drop of cyano to the two wheel collars Preparing the wheel spats replacement part No. Fit the collet 72 and the 5 mm socket-head grubscrew Completing and installing the main undercarriage Fit the inner collets 72 as shown in the picture, and fit the wheels 71 together with the assembled wheel spats on the undercarriage unit Align the parts carefully.

Fit the outer collets 72, and tighten the grubscrews to fix the wheels and spats on the undercarriage. Installing the motor The motor must be attached to the motor bulkhead 61 in such a way that the end of the shaft is located about 10 mm beyond the front face of the bulkhead.

The kit contains a spacer ring 63 which is suitable for the recommended Himax motors long shaft. Attaching the motor bulkhead to the motor mounts The design of the motor mounts 60 and the motor bulkhead 61 allows you to adjust the sidethrust and downthrust of the motor. When the four adjustor screws 64 are fitted flush, the mount is already installed asymmetrically; this arrangement gives maximum sidethrust and no downthrust.

Make the following adjustments to set the motor thrustline at the correct initial angle. Note that we are working from the rear of the bulkhead. Upper left adjustor screw turn Upper right adjustor screw turns Lower left adjustor screw turns Lower right adjustor screw turns Caution: apply the adhesive on the tip of a small screwdriver or similar tool.

Take care not to glue the wheel to the axle! Installing the main undercarriage mount Offer up the undercarriage mount 76 to the recess in the Completing the canopy Insert the latch tongues 33 in the canopy latch clips, and 25 check that they fit correctly.

Place the canopy 5 on the fuselage and press down lightly to position the latch tongues correctly. Carefully open the canopy, bend the latch tongues 33 slightly to one side, and apply cyano to the joint surfaces. Straighten the latch tongues again immediately. Mask off the edge of the canopy using tape. Apply a very thin coat of the primer; just wipe it on and off again, as if you were cleaning the surface.

After this treatment you can paint the canopy using any paint of your choice. Weight down the panels at the centre section and the tip. Carefully slide the styrofoam strip 22 under the wing leading edge until the wing shell is fully supported, then fix the strip in that position.

Now insert the wing cover panel and immediately position if correctly; press it down evenly with the flat of your hand, working from the aileron area towards the thickest part of the wing. Leave the wing in this position no tests! Installing the servos The Nano S aileron servos are installed standing upright in the wings.

The servo leads can be drawn through to the wing root using a length of wire with a hook formed in the end. You may need to use servo extension leads, 8 Place the servos in the recesses in the wing and secure each with a drop of cyano or hot-melt glue applied to the mounting lugs.

Remove the ailerons again. Apply cyano to both sides of the hinges as described previously, then push the ailerons into final 26 position. Aileron pushrods Glue the horns 34 in the recesses in the ailerons using cyano. The aileron linkages are assembled from parts 38,35,34 and 37, as shown in Fig.

Screw the clevis 40 on the threaded end of the pushrod 41 and set it to the correct length. Connect the pushrod using the pushrod connector, as shown in Fig.

At first glance the design bears a passing resemblance to large 2m freestyle machines like the Majestic and Adrenaline. So, what did I discover? The sheet is rolled around the various parts and after carefully removing it from the box I noticed that one end was creased, which I suspected correctly, as it turned out might cause a problem or two during application. Alas, however, the trailing edge of the right wing root section was slightly crushed where it plugs into the fuselage. Fortunately this turned out to be nothing more than a cosmetic issue and can only be seen on very close inspection. Particularly eye-catching are the wheels, spats and spinner.
