I/C FLIGHT GUIDELINES
Made in Vietnam
When ready to fly, first extend the
transmitter aerial.
Operate the control sticks on the
transmitter and check that the control
surfaces move freely and in the
CORRECT directions. ALWAYS land the model INTO the
wind, this ensures that the model lands
at the slowest possible speed.
Switch on the transmitter.
Switch off the transmitter.
Check that the transmitter batteries
have adequate power.
Switch off the receiver.
Switch on the receiver. ALWAYS take off into the wind.
Check that the wings are correctly
fitted to the fuselage. If the model does not respond correctly
to the controls, land it as soon as
possible and correct the fault.
Empty the fuel tank after flying, fuel left
in the tank can cause corrosion and
lead to engine problems.

I/C FLIGHT WARNINGS
Always operate in open areas, away
from factories, hospitals, schools,
buildings and houses etc. NEVER fly
your aircraft close to people or built
up areas.
THE PROPELLER IS DANGEROUS
Keep fingers, clothing (ties, shirt
sleeves, scarves) or any other loose
objects that could be caught or drawn
in, away from the propeller. Take care
at ALL times.
Keep all onlookers (especially small
children and animals) well back from
the area of operation. This is a flying
aircraft, which will cause serious
injury in case of impact with a person
or animal.
NEVER fly near power lines, aerials
or other dangerous areas including
airports, motorways etc.
NEVER use damaged or deformed
propellers or spinners.
DO NOT dispose of empty fuel
containers on a fire, this can lead to
an explosion.
NEVER fly in wet conditions or on
windy or stormy days.
ALWAYS adjust the engine from
behind the propeller, and do not allow
any part of your body to be in line
with the propeller.

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 parts bags.
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 DOLPHIN 40 ARF 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 paint 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
de-bonder 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 chip must be securely attached
to the glow plug.
• Do not flip the propeller with your fingers.
• Keep loose wires and clothing away from the
propeller.
• Do not start the engine if people are near. Do
not stand on the side of the propeller.
• Make engine adjustments from behind the
propeller only. Do not reach around the
spinning propeller.

3. Check the fit of the horizontal stabilizer in its
slot. Make sure the horizontal stabilizer is
square and centered to the fuselage by taking
measurements, but don't glue anything yet.
4. With the horizontal stabilizer correctly aligned,
mark the shape of the fuselage on the top and
bottom of the tail plane using a water soluble /
non-permanent felt-tip pen.
!
5. Remove the stabilizer. Using the lines you just
drew as a guide, carefully remove the covering
from between them using a modeling knife.
When cutting through the covering to remove it,
cut with only enough pressure to only cut
through the covering it's self. Cutting into the
balsa structure may weaken it. This could lead
to possible failure during flight.
2. Draw a center line onto the horizontal stabilizer.

2. Using a modeling knife, cut one length of silicon
fuel line (the length of silicon fuel line is
calculated by how the weighted clunk should
rest about 8mm away from the rear of the tank
and move freely inside the tank). Connect one
end of the line to the weighted clunk and the
other end to the nylon pick up tube in the
stopper.
3. Carefully bend the second nylon tube up at a 45
degree angle (using a cigarette lighter). This
tube will be the vent tube to the muffler.
4. Carefully bend the third nylon tube down at a 45
degree angle (using a cigarette lighter). This
tube will be vent tube to the fueling valve.
When the stopper assembly is installed in the
tank, the top of the vent tube should rest just
below the top surface of the tank. It should not
touch the top of the tank.
FUEL TANK installation
INSTALLING THE STOPPER ASSEMBLY
1. The stopper has been pre-assembled at the
factory.
Do not secure the tank into place permanently until
after balancing the airplane. You may need to
remove the tank to mount the battery in the fuel
tank compartment.
9. Secure the fuel tank using the plate of plywood
and glue it by C.A glue.
5. Test fit the stopper assembly into the tank. It
may be necessary to remove some of the
flashing around the tank opening using a
modeling knife. If flashing is present, make
sure none of it falls into the tank.
6. When satisfied with the alignment of the stopper
assembly tighten the 3mm x 20mm machine
screw until the rubber stopper expands and
seals the tank opening. Do not over tighten the
assembly as this could cause the tank to split.
7. Using a modeling knife, cut 3 lengths of fuel line
150mm long. Connect 2 lines to the 2 vent
tubes and 1 line to the fuel pickup tube in the
stopper.
8. Feed three lines through the fuel tank
compartment and through the pre-drilled hole in
the firewall. Pull the lines out from behind the
engine, while guiding the fuel tank into place.
Push the fuel tank as far forward as possible,
the front of the tank should just about touch the
back of the firewall.
Blow through one of the lines to ensure the fuel
lines have not become kinked inside the fuel
tank compartment. Air should flow through
easily.

the slot.
3. Working from inside the fuselage, slide the
threaded end of the remaining pushrod down
the inside of the fuselage until the pushrod
reaches the exit slot. Carefully reach in with a
small screw driver and guide the pushrod out of
the exit slot.
4. Install the clevis on the rudder pushrod. Make
sure 6mm of thread shows inside the clevis.
5. The control horn should be mounted on the left
side of the rudder at the leading edge, in line
with the rudder pushrod.
6. Drill two 2mm holes through the rudder using
the control horn as a guide and screw the
control horn in place.
7. Attach clevis to the third hole in the control
horn. Install a silicone tube on the clevis.
8. 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 to accommodate the rudder pushrod wire.
9. Plug the rudder servo into the receiver and
center the servo. Install the servo arm onto the

2. Uncoil the receiver antenna completely and
drill a 1/16'' hole in the side of the fuselage,
opposite the muffler, for the antenna to exit.
Secure the end of the antenna to the top the
vertical fin using a rubber band or similar
method.
3. Install the switch on the side of the fuselage
opposite the muffler. Use the faceplate of the
switch as a pattern for drilling the holes and
the cutout for the switch itself.
Balancing
1. It is critical that your airplane be balanced
correctly. Improper balance will cause your
plane to lose control and crash. The center of
gravity is located 75mm back from the
leading edge of the wing at the fuselage
sides. This location is recommended for
initial test flying and trimming. Balance the
Paragon with the fuel tank empty.
2.
Using a couple of pieces of masking tape or a
pen, make a mark on each side of the bottom
of the wing 75mm back from the leading edge.
3. Place your fingers on the marks on bottom of
the wing and carefully lift the plane.
4. If the nose of the plane falls, the plane is
nose heavy. To correct this, try moving your
battery pack back. It that is not enough
change, add a little lead weight to the tail. If
the tail of the plane falls, double check that
you have mounted the battery pack under
the fuel tank. If the airplane is still tail heavy
add lead weight to the firewall or even better,
use a sufficient heavy hub under the spinner.
Receiver & Battery Installation
1. The battery should be wrapped in foam and
mounted under the fuel tank to add in
balancing. We used a 500mah flat pack. The
receiver should be wrapped in foam and
mounted just behind the fuel tank.
2. Plug the throttle servo into the receiver and turn
on the radio system. Check to ensure that the
throttle servo output shaft is moving in the
correct direction. When the throttle stick is
moved forward from idle to full throttle, the
throttle barrel should also open and close using
this motion. If not, reverse the direction of the
servo, using the transmitter.
3. Slide the adjustable metal connector / servo
arm assembly over the plain end of the
pushrod wire. Position the throttle stick and the
throttle trim at their lowest positions.
4. Manually push the carburator barrel fully
closed. Angle the arm back about 45 degree
from center and attach the servo arm onto the
servo. With the carburator barrel fully closed,
tighte the set screw in the adjustable metal
connector.
5. Remove the excess throttle pushrod wire using
wire cutters and install the servo arm retaining
screw.
!
INSTALLING THE THROTTLE
1. Install one adjustable metal connector through
the third hole out from the center of one servo
arm, enlarge the hole in the servo arm using a
2mm drill bit to accommodate the servo
connector. Remove the excess material from
the arm.
After installing the adjustable metal connector
apply a small drop of thin C/A to the bottom
nut. This will prevent the connector from
loosening during flight.
