Masking tape - Straight Edged Ruler - Pen or pencil - Drill and Assorted Drill Bits If exposed to direct sunlight and/or heat, wrinkels can appear. Storing the model in a cool place will let the wrinkles disappear. Otherwise, remove wrinkles in covering film with a hair dryer, starting with low temperature. You can fix the corners by using a hot iron. Bei Sonneneinstrahlung und/oder Wärme kann die Folie erschlaffen bzw. Falten entstehen. Verwenden Sie ein Warumluftgebläse (Haartrockner) um evtl. Falten aus der Folie zu bekommen. Die Kanten können Sie mit einem Bügeleisen behandeln. Nicht zuviel Hitze anwenden Low seting Symbols used throughout this instruction manual, comprise: 1.5mm Drill holes using the stated size of drill (in this case 1.5 mm ) !

It should insert smoothly up to the center line marked above. 3- Slide the other wing half onto the dihedral brace until the wing panel meet. If the fit is over tight, it may be necessary to lightly sand the dihedral brace. 4- Check for the correct dihedral angle. 5- Mix up some 30 minute epoxy and apply a generous amount of epoxy into the wing joiner cavity of one wing half. 6- Coat one half of the dihedral brace with epoxy up to the center line. Install the epoxy-coated side of the dihedral brace into the wing joiner cavity up to the center line, marking sure that the “V” of the dihedral brace is positioned correctly 7- Do the same way with the other wing half. 8- Carefully slide the wing halves together, ensuring that they are accurately aligned. Firmly press the two halves together, allowing the excess epoxy to run out. Clean off the excess epoxy with paper towel and kerosene. IMPORTANT: Please do not clean off the excess epoxy on the wing with strong solvent or pure alcohol, only use kerosene to keep the colour of your model not fade.

Checking for leaks - block the vents and blow into the feed - if in doubt submersing the tank in a blow of water will show up any problems. Carefully install the fuel tank to ensure that they will not shift during flight (secure the fuel tank in place using zip tie). 13- Cowling 1.5mm Cut of shaded portion 3mm Prop. hub 2,5x10mm screw ...........5 ZLIN Z-526 14- Electric motor -Using a aluminum motor mounting plate as a template, mark the plywood motor mounting plate where the four holes are to be drilled. -Remove the aluminum motor mounting plate and drill a 1/8”(3mm) hole through the plywood at each of the four marks marked .

Pull the left and right elevator out of the horizontal stabilizer. 18B Push the horizontal stabilizer into the slot on the fuselage as show. Check the alignment of the horizontal stabilizer by measuring from a fixed point along the center line of the fuselage to the leading edge on each side of the horizontal stabilizer. The distance must be equal on both sides . If not, adjust the stabilizer until the measurements are the same (see picture below: A=A’). Cut away only the covering 18A 18B A’ A A=A’ 18C When you are satisfied with the alignment, use a pencil to trace around the top and bottom of the stabilizer where it meets the fuselage. 18D Cut away only the covering both side 18D Remove the horizontal stabilizer from the fuselage. Using a straight edge and a sharp hobby knife, carefully cut away the covering inside the lines which were marked above. Be cautious not to cut into the wood-this will weaken the structure. ZLIN Z-526 19- Horizontal stabilizer Install the horizontal stabilizer onto the fuselage and adjust the alignment as described in steep 18B. Note: it is important to ensure that the horizontal stabilizer is also level in regards to the fuselage. Apply the thin CA along the area where the covering was removed in the previous step and to the fuselage where the horizontal stabilizer mounts . B=B’ B Apply thin CA glue into the slot where the fuselage meet the horizontal stabilizer. B’ CA CA Apply CA glue both sides. (thin CA) 20- Vertical stabilizer 20A Pull the rudder out of the vertical fin. Carefully, push the vertical fin into the slot on the fuselage as shown. 90 degree triangle 20B Trial fit the vertical fin in position. Using a 90 degree triangle, ensure that the vertical stabilizer is perpendicular to the horizontal stabilizer. Using a pencil, trace around the vertical stabilizer where it meets the fuselage. Remove the vertical stabilizer from the fuselage. ZLIN Z-526 21- Vertical stabilizer the vertical stabilizer from the fuselage. 21A Remove Using s sharp hobby knife, carefully cut away the covering below the lines which were drawn in the previous steep. Do not cut into the woods as this will affect the structural integrity of the stabilizer. Insert the vertical fin into the fuselage, precisely align the vertical stabilizer as described in step 20B. Apply the thin CA glue on the vertical stabilizer where it 21B contacts the fuselage. ! Securely glue together. If coming off during fly, you lose control of your air plane. 90 degree triangle Cut away only the covering (both sides) Apply thin CA CA glue both sides 22- Installing the elevator Without using glue yet, push the elevator and its hinges into the hinge slots in trailing edge of the horizontal stabilizer.
