TOOLS AND SUPPLIES NEEDED.

• Medium C/A glue.

• 30 minute epoxy.

• 6 minute epoxy.

• Hand or electric drill.

• Assorted drill bits.

• Modeling knife.

• Straight edge ruler.

• 2 bender plier.

• Wire cutters.

• Masking tape.

• Thread lock.

• Paper towels.

• Rubbing alcohol

SUGGESTION

To avoid scratching your new airplane, do not unwrap
the pieces until they are needed for assembly. Cover
your workbench with an old towel or brown paper,
both to protect the aircraft and to protect the table.
Keep a couple of jars or bowls handy to hold the
small parts after you open the bag.

NOTE:

Please trial fit all the parts. Make sure you have the
correct parts and that they fit and are aligned properly
before gluing! This will assure proper assembly. The
ASK-21 ELECTRIC 3200 ARF 1/5 SCALE is hand
made from natural materials, every plane is unique
and minor adjustments may have to be made.
However, you should find the fit superior and
assembly simple.

The painted and plastic parts used in this kit are fuel
proof. However, they are not tolerant of many harsh
chemicals including the following: paint thinner, C/A
glue accelerator, C/A glue debonder and acetone. Do
not let these chemicals come in contact with the
colors on the covering and the plastic parts.

SAFETY PRECAUTION:

• This is not a toy

• Be sure that no other flyers are using your radio
frequency.

• Do not smoke near fuel

• Store fuel in a cool, dry place, away from
children and pets.

• Wear safety glasses.

• The glow plug clip must be securely attached to
the glow plug.

• Do not flip the propeller with your fingers.

• Keep loose clothing and wires away from the propeller.

• Do not start the engine if people are near. Do not
stand in line with the side of the propeller.

• Make engine adjustments from behind the propeller
only. Do not reach around the spinning propeller.

PREPARATIONS

Remove the tape and separate the ailerons from
the wing and the elevators from the stab. Use a
covering iron with a covering sock on high heat to
tighten the covering if necessary. Apply pressure
over sheeted areas to thoroughly bond the
covering to the wood.

INSTALLING THE AILERONS

1. Test fit the ailerons to the wing with the hinges.
If the hinges don’t remain centered, stick a pin
through the middle of the hinge to hold it in
position.

CA glue

2. Apply six drops of thin CA to the top and bottom
of each hinge. Do not use CA accelerator. After
the CA has fully hardened, test the hinges by
pulling on the aileron.

3. Place the servo into the servo tray. Center the

3. Place the servo into the servo tray. Center the
servo within the tray and drill 1,6mm pilot holes
through the block of wood for each of the four
mounting screws provided with the servo.

Remove the covering

INSTALLING THE AILERON SERVOS

1. Install the rubber grommets and brass eyelets
onto the aileron servo.

2. Using a modeling knife, remove the covering

from over the pre-cut servo arm exit hole on the
aileron servo tray / hatch. This hole will allow
the servo arm to pass through when installing
the aileron pushrods.

6. Repeat step # 2 - # 5 to install the second
aileron servo in the opposite wing half.

5. Place the aileron servo tray / hatch into the
servo box on the bottom of the wing and drill
1,6mm pilot holes through the tray and the
servo box for each of the four mounting screws.
Secure the servo tray in place using the
mounting screws provided ( 2mm x 12mm ).

4. Using the thread as a guide and using masking
tape, tape the servo lead to the end of the
thread: carefully pull the thread out. When you
have pulled the servo lead out, remove the
masking tape and the servo lead from the
thread.

INSTALLING THE CONTROL HORNS

1. One aileron control horn in positioned on each
aileron. Using a ruler and a pen, locate and
mark the location of the control horn. It should
be mounted on the bottom side of the aileron at
the leading edge, in line with the aileron
pushrod.

2. Drill two 1.6mm holes through the aileron using
the control horn as a guide and screw the
control horn in place.

aileron linkage. After both linkages are
completed, connect both of the aileron servo
leads using a Y-harness you have purchased
separately.

2. Attach the clevis to the outer hole in the control
horn. Install a silicone tube on the clevis.

3. Locate one nylon servo arm, and using wire
cutters, remove all but one of the arms. Using a
2mm drill bit, enlarge the third hole out from the
center of the arm to accommodate the aileron
pushrod wire.

4. Plug the aileron servo into the receiver and
center the servo. Install the servo arm onto the
servo. The servo arm should be perpendicular
to the servo and point toward the middle of the
wing.

5. Center the aileron and hold it in place using a
couple of pieces of masking tape.

6. With the aileron and aileron servo centered,
carefully place a mark on the aileron pushrod
wire where it crosses the hole in the servo arm.

7. Using pliers, carefully make a 90 degree bend
down at the mark made. Cut off the excess
wire, leaving about 4mm beyond the bend.

8. Insert the 90 degree bend down through the
hole in the servo arm. Install one nylon snap
keeper over the wire to secure it to the arm.
Install the servo arm retaining screw and
remove the masking tape from the aileron.

INSTALLING THE AILERON LINKAGES

1. Working with the aileron linkage for now, thread
one nylon clevis at least 14 turns onto one of
the 2mm x 180mm threaded wires.

INSTALLING THE WING

1. Attach the wing to the fuselage as picture.

3. Repeat step # 1 - # 2 to install the control horn
on the opposite aileron.
