Note about Glue Before starting to assemble the airplane, check your glue: S pr e ads om egl u e on a sheet of paper and wait a few minutes. If the paper gets wrinkled or wavy, then, that glue
8、 is not suitable for paper; the aircraft would be deformed and look ugly. A suitable glue is “transparent liquid contact glue” usually used for repairing shoes. They can be found at the “Glues” section in big shopping centres or hardware stores. 4 Suitable glue should have these qualities: -Accurate
9、 application. So that you can easily apply a bead of glue over a narrow paper tab. -Transparent. The airplane will look better if too much glue is applied and it overflows tabs boundaries. -It should dry fast enough. It should be strong enough to stick two pieces together after holding for two minut
10、es. -It should dry slow enough. The glue must allow enough time to manoeuvre the pieces before setting. -And most importantly: The glue must not deform or wrinkle the paper. X www.PaperA Print pages 8 and 9 on normal A4 paper or regular letter paper. Using a paper with a basis weight of 20lb / 80gr/
11、m2 will simplify the balancing process. Print full scale (100%) to avoid the distortion of parts and using option ”Auto-rotate and center pages”. Do not “fit to page” or “shrink to page”. Cut parts over the external lines. Note that you can fold the paper on the lines with the help of the rulers, (t
12、o the opposite side) and then, with your fingers, on the same line, to the correct side to obtain the shape of the final piece. F ol dov e rt heli ne sw itht h eh el pof rulers to obtain the shape of each part. 5www.PaperA X Stick parts by applying glue to the overlapping surfaces. 6 Apply a small a
13、mount of glue. Otherwise, the airplane will look ugly and it will weigh too much.www.PaperA Note about printing Parts Use either letter or DIN A4 formats, preferably with a basis weight of 20lb / 80gr/m2 . There are three pages to be printed on two sheets of paper. Page “opposite 9” must be printed
14、on the reverse side of page 9, in order that the plane is correctly decorated. Check option “Auto-rotate and center pages” but do not check “fit to page” or “shrink to page”. Print at 100% scale. You neednt to print the rest of the document. View it on the screen and zoom in when needed. If you want
15、 to build a static, non-flying model, you can print on high quality paper in high resolution. However if you want a flying model it is better to use normal paper. A weight of 20lb/80gr paper is perfect to fold and fly. The thicker the paper, the more difficult it is to fold and the heavier is the pl

If it stays level and does not fallit is balanced.
22、If it falls forward, the nose is too heavy. Put a load on the tail. If it falls backward, it needs more weight in the nose. Did you paste parts 25, 26 and 27? Add some pieces of paper if needed.

23、 holding it in the line of sight and projecting it along its longitudinal axis. Once you have mastered throwing it at eye level, try to launch it over head for a longer flight. 28www.PaperA 4 Correcting the flight path: Pitch If the aircraft pitches down towards the ground, bend the elevator gently
24、upwards. Repeat the flight. If it still goes down, bend the elevator upwards a little more until the aircraft glides straight. If the gliding path oscillates as shown above the elevator may be deflected too far upwards. Reduce the amount of upward deflection. In this case the nose still needs a litt
25、le more weight. Add some pieces of paper to the nose. 29www.PaperA + If you manage to stabilize the glide path but the flight path is too far downwards the nose may be too heavy. Try to remove part of piece 27 or add weight to the tail and reduce the elevators upward deflection. Correcting the fligh
26、t path: direction In order to correct the turn, gently adjust the angle of the ailerons asymmetrically es shown in the images. The deflections in the pictures are exaggerated; you will obtain the opposite effect. 30 5www.PaperA In case of slight corrections in direction, you can use the rudders. Adj
27、ust them very gently. Correct left turns by deflecting the rudder right Correct right turns by deflecting the rudder left. 31 Left slip: tail steering right, wings steering left. Right slip: Tail steering left, wings steering right. Flight path Flight path Slipped flight has poor a glide ratio. The
28、airplane somehow flies sideways and banks a little. The tail and wings might not be correctly adjusted. Correct left slip by moving the rudder to the left and ailerons steering right. Correct right slip by moving the rudder to the right and ailerons steering left.www.PaperA Advanced Flight 7 Once yo
29、u have calibrated the glide path in pitch and direction, you can try different airplane performances. “Cruise”: The airplane will pitch downwards. To reverse this, raise the elevators a little. The airplane will fly more smoothly Lower the leading edge flaps a little. “Approach”: Lower the LE flaps a little more. Compensate the downward pitch, by raising the elevators if needed. T h eai r pl a new illfl ysl ow e r. 32 “Landing”: Compensate the downward pitch by raising the elevators. The airplane will fly more slowly with a shorter glide path. Lower the LE flaps a little more.
