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.

OPEN AND CLOSE THE CANOPY

FINAL ASSEMBLY
INSTALLING THE SPINNER

Install the spinner back-plate, propeller and

spinner cone. The spinner cone is held in place
using two 3mm x 15mm 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.

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. Strap the battery pack and receiver onto the

wing joiner tube in the fuselage.

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.

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

85-90mm  BACK  FROM  THE  LEADING  EDGE
OF  THE  WING,  AT  THE  FUSELAGE.  This
location is recommended for initial test flying and
trimming.  There  is  a  10mm  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 85-90mm 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.

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.

back of the firewall.

FUEL TANK installation
INSTALLING THE STOPPER ASSEMBLY

1. The stopper has been pre-assembled at the

factory.

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.

2. Carefully cut away the covering material from

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.

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.

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.

3. Slide the cowl back into place. Align the front of

the cowl with the crankshaft of the engine. The
front  of  the  cowl  should  be  positioned  so  the
crankshaft  is  in  the  middle  of  the  precut
opening.  Hold  the  cowl  firmly  in  place  using
several pieces of masking tape.

4. While holding the cowl firmly in position, drill

four 1,6mm pilot holes through both the cowl
and the side edges of the firewall.

5. Using a 3mm drill bit, enlarge the four holes in

the cowling.

Enlarging the holes through the cowl will prevent

the fiberglass from splitting when the mounting
screws are installed.

6. Slide the cowl back over the engine and secure it

in place using four 3mm x 12mm wood screws.

7. Install the muffler. Connect the fuel and pressure

lines to the carburator, muffler and fuel filler
valve. Tighten the screws completely.

ENGINE INSTALLATION
INSTALLING THE THROTTLE PUSHROD HOUSING

1. Install the engine mount into the fire wall using

4mm x 20mm screw.

2. Place the engine into the engine mount and

align it properly with the front of the cowling.
The distance from the firewall to the front of the
engine thrust washer should 110mm.

If your engine is equipped with a remote needle

valve, we suggest installing it into the engine at
this time.

3. Slide the pushrod housing through the hole in

the firewall, through the hole in the forward
bulkhead, and into the servo compartment.

4. Apply a couple of drops of thin C/A to the

pushrod housing where it exits the firewall and
where it passes through the forward bulkhead.
This will secure the housing in place.

5. Using a modeling knife, cut off the nylon pushrod

housing 26mm in front of the servo tray.

INSTALLING THE ENGINE

Locate the long piece of wire used for the throttle

pushrod.  One  end  of  the  wire  has  been
pre-bend  in  to  a  "Z"  bend  at  the  factory.  This
"Z"  bend  should  be  inserted  into  the  throttle
arm of the engine when the engine is fitted onto
the engine mount. Fit the engine to the engine
mount using the screws provided.
