Insert the connecting rod (long) and connecting
rod clamp (long) into the left wing gear in the
orientation shown in the drawing and mount the
assembly on the front frame. Also slide two
knobs onto the crankshaft and insert the tip of
the shaft into the safety cover.
Insert the right wing gear into the front frame.
Insert the wing gear clamp.
Push the wing boom
into the front frame.
Insert the fuselage into the stopper, then
press the rear frame onto the stopper/
fuselage assembly. Insert the fuselage
firmly so that it goes all the way into the
holes of the front and rear frames.
The angled corner of the
fuselage should face the
bottom front.
Assembly time: Approximately 40 minutes

Cut the wing from the wing film
along the printed line and, with
the L and R at the ends of the
wing readably oriented, tape it
onto the portion of tape with the
protective paper peeled off. The
L is the tip of the left wing; the R
is the tip of the right wing.
The carbon shafts must be at their lowest positions
when taping on the wing film! If the film is attached
with the shafts raised, the film will be too tight and the
shafts will be unable to descend.
Tape it to the flat surface and
then remove all the protective
paper.
ape the wing film on, starting at the
tip, taking care not to let slack into
the wing film. Then, progressively
tape on the film by lightly pressing,
moving toward the center, and then
press firmly once
the film is
positioned to permanently attach
the film.

Tape the double-sided tape to the left and right carbon shafts and to the wing boom, as shown in the
drawing, and then peel back 15 mm of protective paper in the areas near the centers of each.
With the carbon shafts at their lowest position, put the bird-style wing film temporarily in place.
Remove the protective paper from the double-sided tape taped to the wing boom and tape on the wing film,
aligning the center line.
Place on the edge of a table or a similar
surface, peel the protective paper from the
double-sided tape taped to the carbon shafts,
and tape on the wing film.
Perform this step one wing at a time.
Cut the double-sided tape to half-length and
tape it to the tail frame as shown in the
drawing.

Hold the crank knobs of the front frame and test the
movement of the wing by winding the elastic a little. When
you try this, check that the part sticking out of the rear
frame wind-up knob catches and is facing upwards.
Cut the tail film from
the wing film along the
printed lines. Place it on
a table with the L and R
backwards, as shown in
the figure.
Gather the two loops
together at the knot
end, pass them
through the rear
frame, and then hook
them onto the wind-
up knob. Press the
knob into the hole in
the rear frame.

The knot can be moved by pulling on
the elastic cord.
Tie with a
loose knot.
Cut the leftovers
so that about
5 cm remains.
Fasten tightly.

Turn the tail film upside down, place it on a
table, position the tail frame so it covers the
film and tape it onto the film.
Double up the elastic cord, pass the loops
through the hole in the frame, and hook the
loops around the wind-up knob.
Hook the other ends of the elastic cord
loops around the crank of the front frame.
When the loop is 25 cm long, tighten the
knot, and then tie another knot at the end.
Insert the tail into the rear frame, adjust
the angle, and secure the tail in place with
the stopper.
Make a loop of about 25 cm out of the
elastic cord.
