  • Page 2 Specification Wingspan approx. 1600 mm Fuselage length excl. spinner approx. 1190 mm Wing area approx. 39.54 dm² Tailplane area approx. 9.0 dm² Total surface area approx. 47.54 dm² All-up weight according to fittings approx. 2500 g Longitudinal dihedral approx. 0.5 ° Downthrust and sidethrust built-in as standard Caution: this model is not a toy! If you are a beginner to this type of powered model, please ask an experienced...
  • Page 3 Creases: Blow warm air over the area and rub down with a soft cloth. Wing warp: Hold the panel twisted gently in the opposite direction to the warp, and apply warm air to remove the creases from the covering. Caution! do not heat the film more than is absolutely necessary. If the air or the iron is too hot, the film may melt and holes may be formed.
  • Page 4 batteries of this type do not reach full capacity until they have been charged and discharged (cycled) several times. You will need two suppressor filters, Order No. 1040, to connect the aileron servos to the receiver, and two further extension leads, 100 mm and 180 mm long. For shock protection the receiver and receiver battery should be packed in soft foam, e.g.
  • Page 5 Assembling the TAXI SPORT II The wing panels Use your fingertips to locate the opening in one wing for the aileron servo, and remove the film over it using the tip of a hot soldering iron or a sharp balsa knife.
  • Page 6 Cut down the servo output lever as shown in the photo below. Fit the output arm on the servo output shaft, facing outward, i.e. towards the wingtip. This arrangement means that the servos do not need to be reversed; this may be useful if you are using a “simple”...
  • Page 7 Fix the horn to the aileron using the pan-head screws and plastic spreader plate supplied. Tighten the screws just to the point where the horn cannot shift - take care not to over-tighten them. Snip off excess screw length using side-cutters before filing back the cut ends flush with the spreader plate.
  • Page 8 Use flat-nose pliers to bend the pushrod at right-angles at the marked point, and cut off excess pushrod material using side-cutters, leaving the bent end around 7 mm long. Connect the pushrod to the servo output arm and push the plastic keeper into place to secure it.
  • Page 9 Now use a felt-tip pen to mark the outline of the fuselage on the tail panels. Melt the film by running a hot soldering iron just inside the marked lines, and peel away the excess film from the joint areas. The prepared tailplane and fin can now be glued to the fuselage, using either UHU coll (white glue) or UHU hart (cellulose cement).
  • Page 10 Fix the tailwheel unit to the fuselage using the two retaining screws provided. The driver lug can now be attached to the bottom of the rudder, so that movement of the rudder is transferred to the tailwheel. Fit the plastic lug on the projecting wire, and fix it to the rudder using a single pan-head screw.
  • Page 11 Installing the rudder and elevator horns Screw an M2 locknut and a clevis onto the threaded end of each rudder and elevator pushrod. Slip the pushrods into the plastic guide tubes and connect the clevises to the horns. The horns should be positioned on the control surfaces in such a way that the clevis linkage hole lines up exactly with the hinge pivot axis.
  • Page 12 Mount the swivel pushrod connector in the outer hole of the throttle servo output arm as shown in the photo. Note that the retaining screw should be tightened just to the point where the barrel rotates smoothly, but without any slop. Set the servos to centre, tape the tail control surfaces at neutral, then mark the point on the pushrods where they cross the linkage holes in the servo output arms.
  • Page 13 The photographs above clarify the method of fitting the wheels: on the left the wheel spat and a cross-section through the wheel, on the right the system minus the wheel. Once the wheels and spats are fitted, the undercarriage legs can be attached to the fuselage using the retaining screws provided.
  • Page 14 The engine / mount assembly can now be attached to the firewall using the M4 x 25 machine screws supplied in the kit. These screws must be secured with a drop of UHU thread-lock fluid to prevent them working loose. At this point the silencer can be mounted on the engine using the screws supplied.
  • Page 15 Push the prepared fueltank into the fuselage and thread the fuel lines through the hole in the firewall. Glue the tank support behind the fueltank to hold it in place. Connecting the fuel lines Connect the silicone fuel line running from the clunk pick-up to the carburettor fuel nipple, and the tube from the overflow to the pressure nipple on the silencer.
  • Page 16 Installing the switch in the fuselage The ON / OFF switch for the receiving system can be installed below the hatch on either side of the fuselage. Cut and file out an opening at the appropriate point to suit the switch toggle or slider you wish to use. Secure the switch unit in the fuselage side using the retaining screws supplied with it.
  • Page 17 The flight battery is held down by a block of foam glued to the fuselage hatch. The foam, Order No. 2905.25, is an ideal material for this. Assembling the TAXI SPORT II We recommend that you permanently connect a suppressor filter, Order No. 1040, to receiver sockets 2 and 5, as this makes it easier to connect the aileron servos when rigging the model.
  • Page 18 Control surface travels Ailerons 10 mm up and down Elevators 11 mm up and down 30% Exponential Rudder 35 mm right and left Please note that the stated control surface travels are just a starting point; you may well wish to adjust them to suit your personal preference and flying style. Important: When fitting and adjusting the various linkages you should ensure that they move freely, without binding, are able to move to their full extent - including trim travel - and...
  • Page 19 Safety notes and warnings relating to model aircraft powered by internal- combustion engines Be sure to read right through the instructions covering assembly and operation of your model before you attempt to operate it for the first time. These safety notes are an integral part of the instructions. Please keep them and the operating instructions in a safe place.

If you have any questions regarding the safe operation of your RC model aircraft, please turn to your local model shop in the first instance as the staff will be pleased to help you.
  • Page 21 Model engines generate a lot of heat. The engine and silencer in particular • become very hot when running, and stay at a high temperature for quite a while. Touching the hot parts can give you serious burns, so take care especially when carrying out adjustments - wear protective gloves.
  • Page 22 Whenever you are working on the engine, make sure that you are on a safe • surface and cannot slip. Get used to holding the model really securely. Take-off and landing strips should be kept free of unauthorised people and •...
