propulsion system of your choice.

Assembly Instrucons

Note: Most joints can be made by the popular method of fing or holding parts together and wicking a very

small amount of thin cyanoacrylate glue (cyano) between them. A strong and lightweight build may be

achieved in this way. Be warned however that this makes an instant and permanent bond, so be sure that

things are right before you apply the glue. Note also that cyano, especially the thin variety, tends to soak into

and harden balsa, This can make subsequent carving and sanding more difficult, and for this reason some

modellers prefer using a soer “white” glue for certain jobs.

Glue in place the reinforcing strips on the

fuselage sides and the top and boom frames.

Allow to dry and then sand.

Remove the excess wood from the fuselage

frames ensuring you keep the reinforcing

strips highlighted in the image.

Prepare the four ply centre cabanes. Glue two of

the cabanes together as shown in the image, when

dry sand the edges but make sure you do not round

the edges. Repeat the process for the other two

pieces.

Prepare the two servo trays and glue together. Once dry sand

the sides square.

No glue in the servo tray channel.

NOTE - Please make sure you make the two

fuselage panel to suit the le and the right

(NOT THE SAME) Glue the ply re-enforcer to the

inside edge of the fuselage side. Use the dowel

holes as a reference point for alignment. When in

posion you should have enough space for the fire

wall to sit just in front of the reinforcing plate but be

flush to the external edge of the balsa fuselage at

the front. Also ensure the channel for the servo tray

does not fill with glue.

This must be to the front of the plane.

Glue the cabane to the fuselage ensuring the correct

orientaon (use image for reference). Allow to dry and sand

flush to the side you will be using for the port side of the

fuselage. Repeat the process and make sure on the second

one you sand the fuselage the opposite side to the first

(starboard).

Gap for the firewall.

Place the tailplane seat in posion and mark

the forward most point on the fuselage side.

This is to prevent the triangle secon going

any further than this point.

Using the four lengths of triangle secon

cut to length a secon to travel from the

rear wing seat area to the rear of the

fuselage. You will need to make a slight

cut as shown in the image to allow to lay

flat.

Make a small cut to allow to lay flat.

Mark this posion.

The rear of the fuselage should look like this.

Repeat the process on the other fuselage

frame but to suit the opposite side.

Trim to allow the triangle secon to lay flat.

this step.

Glue the other side of the fuselage in place at the firewall only.

Use the servo tray as a temporary spacer to keep the fuselage

frames parallel but do not glue the servo tray in posion.

Firewall

Pywood re-enforcing

Balsa fuselage frame

Use servo tray as a spacer(do not glue in place).

While gluing the two sides to the firewall make sure you keep the two frames parallel to each other.

Insert the tailplane seat between the two fuselage

frames and glue in place. It is very important when

you glue this in place that you do not induce a

banana shape to the fuselage.

Glue in place the undercarriage plate.

With the remaining triangle secon re-enforce the

firewall, undercarriage plate and top plate.

Glue in place the top plate ensuring it aligns with the

centre cabanes.

Ensure the frame aligns perfectly

with rear wing seang area

Glue the underside frame in place. Ensure the frame aligns

perfectly with the rear trailing edge wing seang area.

Ensure the frame bus up

to the rear of the cabanes.

Glue the top frame in place ensuring the fin post

cut out aligns to the tailplane seat and the frame

bus up to the rear of the cabanes.

Ensure the fin post cut out

aligns with the cut out in the

tailplane plate .

Before gluing the top frame in place you need to decide

if the rudder servo will be located at the rear or inside the

fuselage. If your choice is at the rear please install the

servo blocks on the inside of the frame. If your choice is

inside then please use a piece of scrap balsa to blank the

servo hole.

Before glueing the centre top plate in place a decision needs to be

made. If your intenons for this Panic are to go electric now is the

me to fabricate a tray system and hatch for your baery.

If you have chosen to go for the IC setup then

please glue the top plate in place.

Insert the dowels supplied to the centre cabane and

the lower fuselage.

Now the fuselage is complete sand all edges and round

the rear fuselage corners. How much you round the rear

of the fuselage is up to you but weight can be saved by

increasing the radiuses. You can now glue the servo tray

in place making sure the rear of the tray aligns with the

reinforcing edge. Make sure you leave adequate space

between the two servo trays to fit your servos. If you have

chosen to put the rudder servo inside the fuselage and

you are installing a throle servo you will need to remove

the parts shown in the image below.

Remove

Remove all excess balsa from the tailplane and fin. Please make sure

you keep the two secons highlighted in the image.

Keep these two reinforcing strips.

On a flat surface glue the leading edge on the front

of the tailplane and glue the trailing edge of the

rudder to the rudder. Insert the reinforcing into

the rudder.

Glue the reinforcing strips in place.

Do not round trailing edge. Either sand flat or V shape.

Sand the tailplane flat and round the leading edge as shown

in the image. The trailing edge of the tailplane you can either

leave flat or you can shape to a V which aids extreme movement.

Under no circumstances round the trailing edge of the tailplane

as it restricts movement of the elevator. The elevator will need

to be V-shaped on the leading edge and the trailing edge needs

to be le flat. Do not round the trailing edge of the elevator as

this will make the control surface less effecve.

Do not round trailing edge. Either sand flat or V shape.

Sand the leading edge of the fin as shown in the image.

The trailing edge of the fin you can either leave flat or

you can shape to a V which aids extreme movement.

Under no circumstances round the trailing edge of the

fin as it restricts movement of the rudder. The rudder

will need to be V-shaped on the leading edge and the

trailing edge needs to be le flat. Do not round the

trailing edge of the rudder as this will make the

control surface less effecve.

Do not round trailing edge.

Do not round trailing edge.

Lay out the necessary parts to build one wing

panel. This comprises of :–

1 x Triangle leading edge

1 x Trailing edge with build jig aached

2 x Top and boom strips

8 x Wing ribs

Separate the trailing edge strip as per the image above.

The lower part of this secon is used as a wing build jig,

but also used as part of the wing build later. Do no discard.

Remove all excess wood from the wing ribs and prepare items

as shown in the image. Please be careful not to split the trailing

edge strips as these have a strip aached to it for building the

wing on a flat surface.

IMPORTANT - Please note that the three ribs

that are grouped together should always form

part of the inboard wing as this area is for the

servo points.

We recommend you build the wing on a building

board so you can pin the trailing edge and wing ribs

square to each other. It is imperave the wing is

built square otherwise when you come to join the

wing panels together it will be hard to align the

wing panels. Before you pin the parts to the board

glue the ribs to the trailing edge strip using a slow

seng glue to allow working me.

Build jig

Glue the lower strip in place with a slow seng

glue to allow working me. Now place the wing

secon on your build board and pin in posion

making sure everything is square. At this point

you can see the importance of the trailing edge

build jig spacing the wing profile from the board.

Build jig spacing the trailing edge off

the build board.

Glue and pin the triangle leading edge in place and

allow to dry.

Make sure the wing ribs are sing vercal

to the build board. As menoned before this is

imperave for when it comes to joining the wing

panels together.

Before starng on the servo trays you have to decide if you are

going to use four servos for ailerons or just two in the lower wing

with joiner rods to the top ailerons. Remove the excess plywood

from the servo trays and ensure the surfaces are clean.

Glue the servo trays in place as shown.

IMPORTANT – it is imperave the servo tray fits between the

ribs on the outboard side of the three ribs that are posioned

closer than the rest. Also it is imperave that the servo tray is

flush with the surface of the rib, if set deeper into the rib the

servo will protrude past the surface of the wing on the reverse

side when installed.

Outboard wing

Inboard wing

Servo trays must be in this posion.

Glue the sheet in place and leave to dry in this posion.

Do not aempt to roll the balsa sheet back into posion

unl fully dry.

Angle the secon to allow for a good

surface contact to the triangle leading edge.

Obtain one of the eight sheets of leading edge sheeng.

The leading edge of the sheet you need to slightly chamfer

the edge so it aligns with the triangle leading edge when

glued in place.

When the glue has set on the leading edge run slow seng glue

on the ribs.

Carefully pull the balsa sheet back over the front of the ribs and pin in place

and allow to dry. Repeat the process on the reverse side.

Now glue the jig strip on the back of the trailing

edge as shown and pin in place.

Carefully remove the trailing edge jig strip and sand

the trailing edge to ensure it is flat.

Install the reinforcing strips as shown in the image

along the length of the wing.

Obtain one of the eight trailing edge strips and glue in

place as per the image and repeat the process on the

reverse side.

Remove the excess

balsa from two of

the eight centre balsa

sheets as shown in the

image.

Glue the centre balsa sheet in place cung it at the trailing edge to fit

the gap between the front and rear sheet. Please note this is to be

aached to the inboard wing area closest to the servo tray which should

always be inboard of the wing NOT outboard. Remove the excess balsa

from the wing rib capping strips and cut to size and glue in place on both

the top side of the wing and boom.

Remove the excess balsa from the wing rib capping strips and cut

to size and glue in place on both the top side of the wing and boom.

Remove all excess wood

overhanging the wing ribs

on either end of the wing

and sand flat. Once

removed glue one of the

four wing ps in place.

IMPORTANT – Please make

sure this is glued on the

out board wingp.

Using the wing rib capping strip make a box area around the

servo tray as shown in the image.

Glue these into place as shown paying aenon to the grain direcon.

Grain direcon front to back.

Remove these and discard so not to get

confused with the others.

Remove the excess wood from the ailerons but keep the small

squares as shown in the image. Please discard the squares

removed from the highlighted points on the image so they are

not confused with the others as the grain direcon differs from

the two types. Also please keep the outer part of the aileron in

parcular the end secon.

Using the outer secon of the aileron that you kept from two

steps ago, cut a secon to fit the secon shown, nong the

grain direcon, and glue in place.

Grain direcon front to back.

Please V-shape the leading edge of the ailerons as shown in the image.

Pay aenon to the image below to show which side is the leading edge.

Leading edge of aileron.

Please note this is for reference only for

posioning of the hinges as this is normally

done once the covering of your choice has

been applied. We recommend four hinges

per aileron. Hinges are not supplied in the kit.

Please note this is for reference only for posioning of the hinges as

this is normally done once the covering of your choice has been applied.

We recommend three hinges for the rudder. Hinges are not supplied

in the kit.

Prepare the four wing panels to be glued together.

Before you commence gluing you need to finalise

the exit points for your aileron servo leads so they

exit the wing inside the fuselage. Install some

drawstring to make it easy when it comes to

installing the servos. Run a secon of masking

tape around the lower part of the wing ready to

receive the other wing panel.

Please note this is for reference only for

posioning of the hinges as this is normally

done once the covering of your choice has

been applied. We recommend four hinges

for the elevator. Hinges are not supplied in

the kit.

Exit holes for servo leads.

Apply the glue and push the two wing panels together, the masking tape

on the boom will prevent any glue seeping out from the boom. Whilst

drying the wing will need to be kept under constant pressure from

wingp to wingp so find some good weights to push the two wing

panels together.

Using glass cloth (not supplied) run a secon around the

centre wing secon and seal the wing. We recommend

ZAP finishing resin. Repeat the process with the other wing.

When dry cut out the holes for the servo leads.

Please round the leading edge of the wing p struts.

To secure the wing p struts use the 19mm press studs.

You will require eight pairs for the build.

Round the leading edges.

Mark a line 15mm in from either end of the wing strut.

Then measure from the leading edge of the strut back

20mm along that line. Then measure again from the

leading edge of the strut 60mm back. This is the

posion for the studs. When posions have been found

press the stud down to mark the outer ring.

60mm

20mm

Leading edge

15mm

Recess the area of the stud about 3-4mm so the base can sit below the

surface of the strut which makes it easier to glue into place. Do not glue

the studs in place as it is easier to cover the strut first, then remove the

covering from the recessed areas and glue the studs in place. It will be

necessary to temporarily tack them in place to mark the posion on the

wing p studs.

50mm

50mm

Posion the undercarriage wire on

the plane as shown and mark the

joining posions of the wire. Remove

and clean all metal joints with a file.

Place back on the plane and temporary

solder the main undercarriage together.

Posion the wings on the plane and pin the strut to the top and boom so

the stud foremost is 50mm from the leading edge on both the top and the

boom. Repeat the same process on the other side. When you are happy

with the posioning of the struts gently press the strut against the wing p

to make an impression on the wing p so the press stud posion can be

located.

Solder these points temporally.

Posion the rubber band supports according to the metal length. If you have an

IC engine and have the silencer running under the fuselage it may be necessary

to lower this to allow the pipe to pass and not interfere with the rubber bands.

Cut 8 – 10mm diameter brass tube

and slit so it creates a C shape.

Wrap this round the joint and solder

in place. Once complete fit the

undercarriage with the supplied

saddle clamps.

This may need to be

lowered to allow for the pipe.

The most common servo installaon:-

2 x Servos on the lower wing for the ailerons with links to the upper wing ailerons.

1 x Rudder servo in the rear of the fuselage with closed loop control wire.

1 x Elevator servo in main servo tray.

1 x Throle servo in main servo tray.

If you have chosen to put the rudder servo in the main servo tray please ensure you modify the servo tray

before installaon.

Remove before tray installaon.

The line of thrust on the Panic is centred around the hole in the firewall, Any power system you are installing

please use this as the centre of your installaon.

With the panic covered and everything installed the C.O.G will need to be checked. This should be 100mm from

the leading edge of the top wing.
