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 
Ka-8b  ELECTRIC  6000 ARF  1/2.5  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.

1

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.

INSTALLING THE CONTROL HORNS

1.  One aileron  control horn in positioned  on each 

aileron.  Remove  the  covering  from  the  aileron 
and secure it.

2

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

3

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.

4

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.

1.  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.

2.    Center  the  aileron  and  hold  it  in  place  using  a 

couple  of  pieces  of  masking  tape.  Adjust  the 
linkage until the aileron and the servo arm are 
both centered and then tighten the nut against 
the clevis. Install the plastic linkball to the servo 
arm. Remember use thread locking compound 
to secure.

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 

150mm  BACK  FROM  THE  LEADING  EDGE 
OF  THE  WING,  AT  THE  FUSELAGE.  This 
location  is  recommended  for  initial  test  flying 
and  trimming.  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  150mm  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. 

!

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.

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.

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.

 Aileron  : 15mm up 

15mm down

 Elevator : 15mm up       15mm down
 Rudder  : 45mm right  45mm left

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.

INSTALLING THE RECEIVER AND BATTERY

1.    Plug  the  servo  leads  and  the  switch  lead  into

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.
