I/C FLIGHT GUIDELINES

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 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 
YAK  54 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 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.

from the fuselage for the stabilizer and remove it.

INSTALLING THE WING TO THE FUSELAGE

Attach the wings to the joiner tube and using the 
nylon thumbscrews to secure the wing panels to the 
fuselage.

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.

6. When you are sure that everything is aligned 

correctly, mix up a generous amount of 30 minute 
epoxy. Apply a thin layer to the top and bottom of 
the stabilizer mounting area and to the stabilizer 
mounting platform sides in the fuselage. Slide the 
stabilizer in place and re-align. Double check all 
of your measurements one more time before the 
epoxy cures. Remove any excess epoxy using a 
paper towel and rubbing alcohol and hold the 
stabilizer in place with T-pins or masking tape.

2. Slide the vertical stabilizer into the slot in the 

mounting platform in the top of the fuselage. Mark

sides of the vertical stabilizer using a felt-tip pen.

3.  Now, remove the vertical stabilizer and using a  

modeling knife, carefully cut just inside the marked 
lines and remove the film on both sides of the 
vertical stabilizer. Just as you did with the horizontal 
stabilizer, make sure you only press hard enough to 
cut the film, not the balsa vertical stabilizer.

4. Slide the vertical stabilizer back in place. Using a  

triangle, check to ensure that the vertical stabilizer is 
aligned 90 degree to the horizontal stabilizer.

5. When you are sure that everything is a aligned 

correctly, mix up a generous amount of 30 minute 
epoxy. Apply a thin layer to the slot in the mounting 
platform and to the vertical stabilizer mounting 
area. Apply epoxy to the lower rudder hinge. Set 
the stabilizer in place and  re-align. Double check 
all of your measurements once more before the 
epoxy cures. Remove any excess epoxy using a 
paper towel and rubbing alcohol and hold the 
stabilizer in place with T-pins or masking tape.

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

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.

    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. To secure the fuel tank in place, apply a bead of 

silicon sealer to the forward area of the tank, 
where it exits the fuselage behind the engine 
mounting box and to the rear of the tank at the 
forward bulkhead.

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.

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.

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 105mm 
BACK FROM THE LEADING EDGE OF THE 
WING, AT THE FUSELAGE. This location is 
recommended for initial test flying and trimming. 
There is a 5mm margin forward and aft. BALANCE 
A PLANE UPSIDE DOWN WITH THE FUEL TANK 
EMPTY.

2. Mount the wing to the fuselage. Using a couple 

of pieces of masking tape, place them on the 
top side of the wing 105mm back from the 
leading edge, at the fuselage sides.

3.  Turn the airplane upside down. Place your 

fingers on the masking tape and carefully lift the 
plane .

4. If  the nose of the plane falls, the plane is nose 

heavy. To correct this first move the battery pack 
further back in the fuselage. If this is not 
possible or does not correct it, stick small 
amounts of lead weight on the fuselage under 
the horizontal stabilizer. If the tail of the plane 
falls, the plane is tail heavy. To correct this, 
move the battery and receiver forward or if this 
is not possible, stick weight into the firewall. 
When balanced correctly, the airplane should sit 
level or slightly nose down when you lift it up 
with your fingers. 

FLIGHT PREPARATION

 PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver 

batteries  before your first day of flying.

2. Check every bolt and every glue joint in your plane 

to ensure that everything is tight and well bonded.

3. Double check the balance of the airplane. 

4. Check the control surface.

5. Check the receiver antenna . It should be fully 

extended and not coiled up inside the fuselage.

6. Properly balance the propeller.

Aileron Control

 LATERAL BALANCE

After you have balanced a plane on the C.G. You 
should laterally balance it. Doing this will help the 
airplane track straighter.

5. Turn the airplane upside down. Attach one loop of 

heavy string to the engine crankshaft and one to 
the tail wheel wire. With the wings level, carefully 
lift the airplane by the string. This may require two 
people to make it easier.

6. If one side of the wing fall, that side is heavier than 

the opposite. Add small amounts of lead weight to 
the bottom side of the lighter wing half's wing tip. 
Follow this procedure until the wing stays level 
when you lift the airplane.

CONTROL THROWS

1. We highly recommend setting up a plane using the 

control throws listed.

2. The control throws should be measured at the 

widest point of each control surface.

3. Check to be sure the control surfaces move in the 

correct directions.

INSTALLING THE SWITCH

1. The switch should be mounted on the fuselage side, 

opposite the muffler, close enough to the receiver so 
the lead will reach. Use the face plate of the switch cut 
out and locate the mounting holes.

2. Cut out the switch hole using a modeling knife. Use a  

2mm drill bit and drill out the two mounting holes 
through the fuselage side.

3. Secure the switch in place using the two machine 

screws provided with the radio system.

INSTALLING THE RECEIVER AND BATTERY

1.  Plug the servo leads and the switch lead into 

the receiver. You may want to plug an aileron 
extension into the receiver to make plugging in 
the aileron servo lead easier when you are 
installing the wing. Plug the battery pack lead 
into the switch.

2.  Wrap the receiver and battery pack in the 

protective foam to protect them from vibration. 
Use a rubber band or masking tape to hold the 
foam in place.

3. Position the battery pack and receiver behind 

the fuel tank. Use the two light plywood pieces, 
placed over the battery and receiver and glue to 
the fuselage sides to hold the battery  and 
receiver securely in place. Use 15mm triangle 
pieces glued between the fuselage sides and 
the plywood pieces to reinforce the joints.

     Do not permanently secure the receiver and 

battery until after balancing the model. 

4. Using a 2mm drill bit, drill a hole through the 

side of the fuselage, near the receiver, for the 
antenna to exit.

FINAL ASSEMBLY

PARTS REQUIRED
·  (1) Spinner
·  (2) 3 mm x 20mm wood screw.

INSTALLING THE SPINNER

Install the spinner back-plate, propeller and 
spinner cone. The spinner cone is held in place 
using two 3mm x 20mm wood screws.

The propeller should not touch any part of the 
spinner cone. If it dose, use a sharp modeling 
knife and carefully trim away the spinner cone 
where the propeller comes in contact with it.

Cowl area cutout 
for proper airflow 
to carburetor.
