If the tail fins have been previously assembled, please go directly to the Instructions on the next page.
Tail Fin Assembly
From the Bionics Kit, locate the bag containing the tools. Next, locate the bags containing the small screws and nuts
(long and short) and the plastic support pieces (large and small). You will use the shorter screws and the smaller
support pieces to assemble the small tail fins.
To assemble a tail fin, attach the small support pieces to the inside of the fin using the shorter screws, nuts, and
tools. Repeat for the other tail fin.

Instructions
Required items: material for distance plates, template for distance plates, scissors,
distance keepers
Print the template for the distance plates (located in the Downloads section on the
bionics4education website) and draw six or more distance holders on the plate material.
Cut out the plates with scissors and cut out the four holes marked on the template.

Required items: adapter, 3 cable ties (long)
Pass three long cable ties through the outer holes of the adapter until the cable tie heads
rest on top of the adapter.
Required items: adapter, 2 distance plates, 3 distance keepers
Start by threading a distance plate. Then thread one distance keeper onto each cable tie
and then another distance plate is threaded on.

Required items: tube (blue)
Push the blue tube through the hole in the middle of the distance plates and into the
middle hole of the adapter.
Required items: distance plates, distance keepers
Continue to thread the distance plates and distance keepers alternately until the material
is used up, or the length of the cable ties is no longer sufficient. End with a distance plate.
The trunk should consist of about 6 layers.

Required items: 3 large servo motors, 3 cable ties, 3-armed holder
Insert the 3 servo motors of the same size (not waterproof) into each slot of the 3-armed
holder and fasten them with a cable tie. Mount the servo motors on the side of the larger
opening in such a way that the rudder horns point inwards.
Pass the servo motors' connector cables through the hole at the base of the three arms.

Required items: scissors
Cut the blue tube approximately 1 inch (2.54 cm) past the last threaded distance plate.
Required items: 3-armed holder
Thread the 3-armed holder onto the last distance plate at the end of the trunk by passing
the blue tube through the hole in the middle of the holder. The smaller opening points in
the direction of the trunk and the servo motors in the other direction.

Guide each cable tie from the trunk through the one side of the rowing horn that appears
below it.
Required items: 3 cable ties
Attach each of the three cable ties that you guided through the rudder horns to the
rudder horn with an additional cable tie.

Required items: 2 tail fins (small), 4 cable ties, adapter (for gripper), 3-armed holder, 2
springs
Insert (slide) the two small tail fins into the two holders located on the adapter.
12
Attach the two small tail fins to the adapter
with a cable tie. To do this, guide the cable
tie through the hole on the side of one tail
fin. Then pass the cable tie through the side
hole of the other tail fin. Add another cable
tie to the end of the first cable tie to act as a
stop. Shorten the cable tie.
Next, loop a long cable tie around the cable tie
between the two fins and then insert the end into the
center hole of the adapter (through the blue tube).
Secure the cable tie to the bottom of the 3-armed
holder using a cable tie as a stop.
Attach the two springs to the gripper adapter.
