INTRODUCTION

Congratulations and thank you f or purchasing the Top

Flite Control Line Score ARF.The Score is capable of

performing all AMA stunt maneuvers; however, it is

also a plane that’s suitable even for relative

newcomers to control line flight. The pre-covered

Score assembles quickly and easily with a bolt-on

wing and stabilizer.Access hatches in the tail section

allow elevator control throw adjustment at the field,

and a removable wing tip weight access hatch allows

you to add or subtract tip weight between flights to

fine tune the model. The leadouts can even be

adjusted by a quick turn of a screwdriver. Whether

flown casually or in competition, the Score is sure to

provide you with impressive control line performance.

For the latest technical updates or manual corrections

to the Score Precision Control Line ARF visit the Top

Flite web site at www.top-flite.com. Open the

“Airplanes” link, then select the Score Precision

Control Line ARF. If there is new technical information

or changes to this model, a “tech notice” box will

appear in the upper left corner of the page.

If you have not flown a control line stunt model

before, we recommend that you get the assistance

of an experienced pilot in your club for your first

flights. If you’re not a member of a club, your local

hobby shop has information about clubs in your area

whose membership includes experienced pilots.

AMA

In addition to joining a control line club, we strongly

recommend you join the AMA (Academy of Model

Aeronautics). The AMA is the governing body of

model aviation and membership is required to fly at

AMA clubs. Though joining the AMA provides many

benefits, one of the primary reasons to join is liability

protection. Coverage is not limited to flying at

contests or on the club field. It even applies to flying

at public demonstrations and air shows. Failure to

comply with the Safety Code (excerpts printed in the

back of the manual) may endanger insurance

coverage. Additionally, training programs and

instructors are available at AMA club sites to help

you get started the right way. There are over 2,500

AMA chartered clubs across the country.Contact the

AMA at the address or toll-free phone number below:

YOURSELF & OTHERS

FOLLO W THESE IMPORT ANT

SAFETY PRECAUTIONS

1.Your Score Precision Control Line ARF should not

be considered a toy, but rather a sophisticated,

working model that functions very much like a full-

size airplane. Because of its performance

capabilities, the Score Precision Control Line ARF, if

not assembled and operated correctly, could

possibly cause injury to yourself or spectators and

damage to property.

2. You must assemble the model according to the

instructions. Do not alter or modify the model, as

doing so may result in an unsafe or unfly able model.

In a few cases the instructions may differ slightly

from the photos. In those instances the written

instructions should be considered as correct.

3.Y ou must take time to build straight, true and strong.

4.You must use lines that are in first-class condition,

and a correctly sized engine and components

throughout the building process.

- 2 -

5. You must correctly install all pushrods and other

components so that the model operates correctly on

the ground and in the air.

6. You must check the operation of the model before

every flight to insure that all equipment is operating and

that the model has remained structurally sound. Be

sure to check clevises or other connectors often and

replace them if they show any signs of wear or fatigue.

7. If you are not already an experienced control line

pilot, you should fly the model only with the help of

a competent, experienced control line pilot.

8. While this kit has been flight tested to exceed

normal use, if the plane will be used for extremely

high stress flying, or if an engine larger than one in

the recommended range is used, the modeler is

responsible for taking steps to reinforce the high

stress points and/or substituting hardware more

suitable for the increased stress.

9.WARNING:The cowl and wheel pants included in

this model are made of fiberglass, the fibers of

which may cause eye, skin and respiratory tract

irritation. Never blow into a part to remove fiberglass

dust, as the dust will blow back into your eyes.

Always wear safety goggles, a particle mask and

rubber gloves when grinding, drilling and sanding

fiberglass parts. Vacuum the parts and the work

area thoroughly after working with fiberglass parts.

Remember: Take your time and follow the

instructions to end up with a well-built model

that is straight and true.

Before starting to build, compare the parts in this kit

with the Parts List and note any missing parts. Also

inspect all parts to make sure they are of acceptable

quality. If any parts are missing, broken or defective, or

if you have any questions about building or flying this

airplane, please contact Top Flite at the address or

telephone number below. If requesting replacement

parts, please provide the full kit name (Score Precision

Control Line ARF) and the part numbers as listed in the

Parts List.

ASSEMBLE THE WING

Install Flaps

❏ 1. Carefully remove the tape holding the flaps to

the wing panels. Cut the covering from the control

line bellcrank access hole as well as the flap joiner

wire groove located in the center of the wing trailing

edge. If necessary, trim the covering from the two

wing bolt holes.

❏ 2. Cut the included 2" x 9" [51 x 229 mm] CA hinge

strip into 3/4" x 1" [19 x 25 mm] hinges as shown in

the drawing. Clip the corners of each hinge to allow

them to fit in the hinge slots easier.

❏ 3. Locate the holes and slots for the flap joiner

wire at the inside leading edge of both flaps and trim

the covering away. Temporarily install CA hinges

halfway into each of the pre-cut hinge slots in the

flaps.Test fit the flap joiner wire (the larger of the two

included joiner wires) into the joiner wire holes with

the control horn pointing up.

❏ 4. Temporarily attach the flaps to the wing by

sliding the CA hinges into their matching pre-cut

slots.View the trailing edges of the flaps from the end

of the wing. See if the flaps are parallel with each

other (have the same “up” and “down”).If necessary,

“tweak”, or bend the joiner to align the flaps.Be sure

to remove the joiner wire from the flaps before

attempting to bend it.

❏ 5. Remove the hinges and trim the covering from

the pre-cut CA hinge slots both on the wing and the

flaps. Drill a 3/32" [2.4 mm] hole into the center of

each hinge slot.

❏ 6. Insert the hinges into the slots in both flaps.Use

a T-pin to help keep the hinges centered in the slots

during assembly.

❏ 7. Roughen up the por tions of the joiner wire that

fit into the flaps with sandpaper. Clean the wire with

denatured alcohol. Mix a small batch approximately

7.5 cc [1/4 oz] of 30-minute epoxy. Use a piece of

wire or a toothpick to apply epoxy to the holes and

grooves in the flaps for the joiner wire. Coat the

matching halves of the joiner wire with epoxy, and

then insert it into the flaps. Join the flaps to the wing

by inserting the hinges into their mating slots in the

wing. Apply thin CA to the center of the hinges on

both sides. The hinges will secure the flaps in place

while the epoxy on the joiner wire cures.Wipe away

any excess epoxy with alcohol.

Install Flap Linkage

❏ 1.Thread a 2 mm nut, silicone clevis retainer, and

a metal clevis onto the flap pushrod wire.

❏ 2. Feed the bent end of the pushrod wire through

the cutout in the sheeting near the trailing edge of the

wing. Connect the pushrod to the outer hole on the

control line bellcrank.

❏ 3. With the bellcrank in the center position, adjust

the clevis until the flaps are neutral when the clevis is

connected to the middle hole on the flap joiner control

horn. Slide the silicone clevis retainer onto the clevis,

add threadlocking compound to the pushrod threads,

and tighten the 2 mm nut against the clevis to secure

it into place.

ASSEMBLE THE T AIL SECTION

Install Elevators

❏

1. Trim the covering from the two mounting holes

on the horizontal stabilizer and the elevator joiner

wire groove located in the center of the stab trailing

edge. As you did with the wing and flaps, trim the

covering from the pre-cut CA hinge slots both on the

stabilizer and the elevators.

❏ 2. Locate the holes and slots for the elevator joiner

wire at the inside leading edge of both elevators and

trim the covering away. Temporarily install CA hinges

halfway into each of the pre-cut hinge slots in the

elevators .Test fit the elevator joiner wire into the joiner

wire holes with the control horn pointing down.

❏ 3.T empor arily attach the ele vators to the stabilizer

by sliding the CA hinges into their matching pre-cut

slots.View the trailing edges of the elev ators from the

end of the stab. See if the elevators are parallel with

each other (have the same “up” and “down”). If

necessary, “tweak” the joiner to align them. Remove

the joiner wire from the elevators to do this.

- 6 -

❏ 4. Roughen up the por tions of the joiner wire that

fit into the elevator with sandpaper. Clean the wire

with denatured alcohol. Mix a 7.5 cc [1/4 oz] batch of

30-minute epoxy. Use a piece of wire or a toothpick

to apply epoxy in the hole and groove in the elevator

for the joiner wire of only one elevator. Coat the

matching half of the joiner wire with epoxy, and then

insert it into the elevator.Secure the joiner wire to the

elevator while the epoxy cures.

❏ 5. After the epoxy has cured, reinsert the hinges

into that elevator and attach it to the stabilizer.

Position the elevator so that the elevator joiner

control horn is centered in the groove in the trailing

edge of the stab. Using the same procedure as the

flaps, permanently attach the elevator to the stab.

❏ 6.Maneuver the partially assembled stabilizer into

the fuselage. Using two 3 x 25 mm SHCS and two

3 mm washers, permanently mount the stab to the

fuselage. To prevent the screws from backing out,

use thread-locking compound.You can also glue the

stab into place with epoxy.

❏ 7. Just as you did with the wing, mix another small

batch of 30-minute epoxy and attach the other

elevator in the same manner. Before the epoxy cures,

secure the hinges with thin CA glue. The hinges will

hold the flap in place while the epoxy cures.

Install Elevator Linkage

❏ 1. Loosely install a 2 mm nut onto each end of the

remaining pushrods.Install a metal clevis with silicone

retainer onto one end of each remaining pushrod wire.

Thread the ends of the pushrod wires that only have a

nut installed on them into the ends of the aluminum

pushrod. Adjust the clevises and pushrod wires inside

the aluminum pushrod so that the total length of the

assembled pushrod is 18-3/4" [475 mm]. Be sure to

use threadlocking compound on the pushrod threads.

❏ 2. Slide the assembled pushrod through the

fuselage. Temporarily attach the clevis to the middle

hole in the elevator control horn.

❏ 3. Tighten the nut against the clevis at the other

end of the pushrod near the wing saddle. Be sure

that the clevis is threaded on about 6mm [1/4"].

❏ 4.Install the elevator control horn access hatches

using eight 2 x 6 mm self-tapping screws.

FINISH THE WING

Test Fit the Wing

❏ 1. Cut the covering from the holes in the front of the

wing and glue in the wing dowels with epoxy.Tap the

dowels into place as far as they will go into the holes.

❏ 2. Using two 4 x 55 mm screws and two 4 mm

washers, test fit the wing to the fuselage.

- 7 -

Install the Belly Pan

❏ 1. Align the belly pan into position and tape it to

the fuselage.Use a felt tip pen to trace its shape onto

the wing.

❏ 2. Remove the belly pan and wing. Use a shar p,

new knife blade or a soldering iron (see “Hot Tip”) to

cut the covering from the wing 1/16" [2 mm] inside

the lines.If using a knife, use a light touch and great

care not to cut into the sheeting under the covering

or the wing will be weakened. After cutting the

covering, use denatured alcohol and a tissue to

clean the ink lines from the covering. Then, peel off

the covering.

HOW TO CUT COVERING FROM BALSA

Use a soldering iron to cut the covering from the stab.

The tip of the soldering iron doesn’t have to be sharp,

but a fine tip does work best.Allow the iron to heat fully .

Use a straightedge to guide the soldering iron at a

rate that will just melt the covering and not burn into

the wood. The hotter the soldering iron, the faster it

must travel to melt a fine cut.Peel off the covering.

❏ 3. Trim the covering from the underside edges of

the belly pan.Epoxy the belly pan to the wing and cut

away the covering from the wing bolt holes if you

have not already done so.Wick thin CA glue into the

wing bolt holes to harden the wood in this area.

Attach the Wing

❏ 1. Fit the two wing dowels into their mating holes

in the fuselage. While tilting the trailing edge of the

wing away from the fuselage, use needle nose pliers

to connect the elevator pushrod to the outer hole in

the flap control horn. Secure the clevis with the

silicone retainer.

❏ 2. Using the 4 x 55 mm screws and 4 mm washers,

secure the wing to the fuselage.

LANDING GEAR

Assemble the Main Gear

❏❏

1. Slide the landing gear wire through the hole in

the wheel pant. Center a nylon strap over the wire

1/2" [13 mm] above the axle hole and drill 1/16" [1.6 mm]

holes through the strap and into the pant for the strap

screws.Temporarily secure the strap with two 2 x 10 mm

self-tapping screws. Back the screws out and apply a

few drops of thin CA to the screw holes. Be sure not to

block the holes with too much CA, and allow the glue to

dry completely before reinserting the screws.

❏❏2. Rough up the inside of the wheel pant with

sandpaper.Clean the area with alcohol and test fit the

retainer plate.Sand or trim the plate as necessary for

it to lay flat on the pant.Use epoxy to attach the plate

to the pant. Dab a bit of petroleum jelly to the end of

the landing gear wire and fit it into the retainer plate.

The jelly will prevent epoxy from sticking to the wire.

The landing gear wire will hold the plate in the correct

position while the epoxy cures.

❏❏3.Thread 3 mm set screws into two 4 mm wheel

collars. Install the wheel into the wheel pant by

securing a wheel collar to each side of it as shown in

the picture. File a small flat spot on the gear wire

where the set screws will be tightened. Be sure that

the wheel rotates smoothly on the landing gear wire.

Add oil to the gear wire if necessary.

❏ 4. Repeat these steps for the other wheel pant.

❏ 5.Test fit the landing gear wire into the wing. Make

any necessary adjustments like rounding over the

edge at the top of the hole for the gear wire to sit flat.

Center two nylon straps over the gear wire and mark

the holes for the straps.Drill 1/16" [1.6 mm] at those

marks. Use four 2 x 10 mm self-tapping screws to

install the gear. Reinforce the holes with thin CA as

done in previous steps.

Assemble the Tail Gear

❏ 1. Thread a 3 mm set screw into the 2 mm wheel

collar. Slide the tail wheel onto the tail wheel wire

followed by the wheel collar. Use thread-locking

compound to secure the set screw. Be sure the tail

wheel rotates freely when the set screw is tightened.

Oil the wheel if necessary.

FLAT SPOTS

❏ 2. Locate the groove for the tail gear wire on the

underside of the fuselage and trim the covering awa y.

The hole at the front of the groove for the tail gear

wire is approximately 9-1/2" [241 mm] from the aft

end of the fuselage.Insert the tail wire into the groove

and secure it with a nylon strap and two 2 x 10 mm

self-tapping screws.

ENGINE AND FUEL SYSTEM

Mount the Engine

There are two engine mounting templates at the back

of this manual for the SuperTigre

®

.51 C/L engine and

the O.S. Max .40 LA-S engine. If you are not using

either of these engines, you will need to make y our own

mounting template based on the size of your engine.

❏ 1.Cut out the template from the back of this manual

that matches your engine. Align the dashed lines on

the template with the cross-hairs on the firewall and

tape the template in place. Use a T-pin or a small drill

bit to transfer the location of the f our mounting holes to

the firewall.

❏ 2.Remove the template and drill the mounting holes

with a 7/32" [5.6 mm] drill bit. Cut the sides from two

4mm blind nuts as shown.Install four 4 mm blind nuts

into the back of the holes.Draw the blind nuts tight into

the firewall by threading a 4 x 20 mm screw and 4 mm

washer through the engine mount and firewall into the

blind nuts and tightening the screw.

❏ 3. Install the engine mount halves inverted to the

firewall using four 4 x 20 mm screws, four 4 mm

washers, and four 4 mm lock washers.

❏ 4. Position the engine so that the drive washer is

4-1/8" [105 mm] from the firewall.Mark the positions of

the engine mounting holes onto the mounting rails (we

used a Great Planes Dead Center

™

Engine Mount

Hole Locator, GPMR8130) and drill the holes with a

1/8" [3.2 mm] drill bit.

four 3 mm nylon locknuts.

Assemble and Install the Fuel Tank

❏ 1. Install the three metal tubes into the black

stopper.The tubes should protrude about 1/2" [12 mm]

from the top of the stopper.Install the two metal plates

on the top and bottom of the stopper and secure them

loosely with the screw .Cut the fuel tubing for the clunk

to 3" [76 mm] and install it onto the shorter tube. The

other end of the fuel tubing receives the fuel pickup

clunk. Bend one long tube so that the inside end just

reaches the top of the tank when installed.This will be

the vent (pressure) line.The humped side of the tank

with the two grooves points do wnward when installed

into the fuselage.The other long tube remains straight.

This is the line for filling the tank.

❏ 2. Press the stopper into the fuel tank and secure it

by tightening the screw. Identify the three tubes with a

marking if necessary. Confirm that the clunk moves

around inside freely and reaches the back of the tank.

❏ 3. Use epoxy thinned with denatured alcohol,

epoxy or fuel proof paint to fuel proof the fuel

tank compartment.

❏ 4. Use 1/4" [6 mm] foam rubber (not included) to

line the top of the fuel tank where it will be held against

the fuel tank mounting plate inside the fuselage. Feed

the long tie straps through the rectangular cutouts on

the mounting plate. Position the tank inside the fuse

with the tank neck passing through the hole in the

firewall.When you are satisfied with the fit, draw the tie

straps tight. Cut away the ends of the tie straps.

❏ 5.Install the fuel tank hatch door with four 2 x 6 mm

self-tapping screws.Reinforce the holes with thin CA.

FINISHING THE MODEL

Install the Cowl

❏ 1. Use a high-speed rotary tool with a cutting bit to

cut an air inlet hole and an outlet in the cowl that is

large enough to accommodate the head of the

engine that you are using.

- 11 -

❏ 2. Place a 6" [150 mm] long piece of masking tape

onto the fuselage over the three mounting blocks as

shown above. Draw a line 4" [102 mm] long starting

at the center of the cowl mounting blocks onto each

piece of tape.

❏ 3. Place the cowl on the fuselage and mount the

spinner backplate. There should be approximately

3/32" [2 mm] between the spinner and the cowl.Align

the cowl so that the spinner backplate is centered.

When satisfied with its position, use tape to hold the

cowl in place or ask a helper to hold it steady.

❏ 4. Using the lines you drew on the masking tape,

measure back 4" [100 mm] from the aft ends of the

lines and transfer the marks onto the cowl. These

marks will be the screw locations for the cowl

mounting screws. Drill 1/16" [1.6 mm] holes at the

three marks on the cowl into the cowl mounting blocks .

❏ 5. Remove the cowl and take off the masking tape.

Replace the cowl onto the fuselage and attach the

cowl with three 2 x 6 mm self-tapping screws and

reinforce the holes with thin CA glue.

❏ 6. Remove the cowl and insert the muffler screws

into the crankcase of the engine. Reinstall the cowl

and position the screws so they contact the inside of

the cowl and mark their location. Remove the cowl

again and cut holes at your marks. Insert the muffler

screws through the holes into the engine to confirm

that the holes are in the correct position.

❏ 7. Remove the cowl one more time. Line the

muffler against the muffler screw holes on the cowl

and trace its shape. Carefully cut out a hole for the

muffler.Trim the hole until you get a good fit.With the

cowl still removed, attach your fuel lines. Also,

consider where your needle valve is positioned. For

the engine shown in this manual, the remote needle

valve was mounted on its side and an access hole

was drilled in the cowl at that location.

- 12 -

❏ 8. Reattach the cowl and secure the muffler to the

engine.Depending on the engine being used, you may

need to drill small access holes into the cowl to tighten

the muffler screws.For the engine shown, an allen key

was inserted through the hole for the needle valve and

the air intake. When filling the tank, fuel will overflow

through the vent line when full. A 3 x 6 mm screw is

included with the kit to be used as a fill line plug.

❏ 9. Reinstall the 2" [51 mm] spinner and propeller.

Install the Canopy

❏ 1. Trim the canopy along the molded cut lines.

❏ 2. Use masking tape to temporarily secure the

canopy to the fuselage.Drill four 1/16" [1.6 mm] holes,

evenly spaced, on the bottom sides of the canopy and

into the fuselage. Thread a 2 x 6 mm self-tapping

screw into each hole and back it out.Use thin CA glue

to harden the screw holes. Attach the canopy to the

fuselage using four 2 x 6 mm self-tapping screws.

Apply the Decals

1. Use scissors or a sharp hobby knife to cut the

decals from the sheet.

2. Be certain the model is clean and free from oily

fingerprints and dust. Prepare a dishpan or small

bucket with a mixture of liquid dish soap and warm

water–about one teaspoon of soap per gallon of water .

Submerse the decal in the soap and water and peel off

the paper backing.Note: Even though the decals have

a “sticky-back” and are not the water transfer type,

submersing them in soap and water allows accurate

positioning and reduces air bubbles underneath.

3. Position the decal on the model where desired.

Holding the decal down, use a paper towel to wipe

most of the water away.

4. Use a piece of soft balsa or something similar to

squeegee remaining water from under the decal.

Apply the rest of the decals the same way.

GET THE MODEL READY TO FLY

Balance the Model (C.G.)

At this stage the model should be in ready-to-fly

condition with all of the systems in place including

the engine, landing gear, and all hardware.

More than any other factor, the C.G. (balance

point) can have the greatesteffect on how a model

flies, and may determine whether or not your first

flight will be successful.If you value this model and

wish to enjoy it for many flights, DO NOT

OVERLOOK THIS IMPORTANT PROCEDURE. A

model that is not properly balanced will be

unstable and possibly unflyable.

- 13 -

- 14 -

❏ 1. Use a felt-tip pen or 1/8" [3 mm]-wide tape to

accurately mark the C.G.on the bottom of the wing on

both sides of the fuselage.The C.G. is located 4-1/8"

[105 mm] back from the leading edge of the wing.

❏ 2.With the wing attached to the fuselage, all parts

of the model installed (ready to fly) and an empty fuel

tank, place the model on a Great Planes CG

Machine

™

, or lift it at the balance point you marked.

❏ 3. If the tail drops, the model is “tail heavy”, and

weight must be added to the nose to balance. If the

nose drops, the model is “nose heavy”;weight must be

added to the tail to balance. If additional weight is

required, nose weight may be easily added by using a

“spinner weight”(GPMQ4645 for the 1 oz [28 g] weight,

or GPMQ4646 for the 2 oz [57 g] weight). If spinner

weight is not practical or is not enough, use Great

Planes (GPMQ4485) “stick on” lead. A good place to

add stick-on nose weight is to the firewall (don’t attach

weight to the cowl–it is not intended to support weight).

Begin by placing incrementally increasing amounts of

weight on the bottom of the fuse over the firewall until

the model balances. Once you have determined the

amount of weight required, it can be permanently

attached. If required, tail weight may be added by

securing it to the inside of the hatch doors.

Note: Do not rely upon the adhesive on the back of

the lead weight to permanently hold it in place. Over

time, fuel and exhaust residue may soften the

adhesive and cause the weight to fall off. Use #2

sheet metal screws, RTV silicone or epoxy to

permanently hold the weight in place.

❏ 4. IMPORTANT: If you found it necessary to add

any weight, recheck the C.G. after the weight has

been installed.

Wing Tip Weight

The Score Control Line ARF includes 1-3/4 oz [53 g] of

steel shot. We suggest starting out by using 1 oz of

stick-on lead weight applied to the underside of the wing

at the tip near the tip weight hatch door.Add or subtract

weight after test flying the model to determine the final

amount needed based on flying preference. You can

then permanently add tip weight to the model by mixing

the appropriate amount of steel shot with epoxy and

pouring it into the tip weight compartment. When the

epoxy has cured, screw the tip weight hatch door to the

wing using four 2 x 6 mm screws or glue it into place.

PREFLIGHT

Balance Propellers

Carefully balance your propeller and spare propellers

before you fly. An unbalanced prop can be the single

most significant cause of vibration that can damage

your model. Not only will engine mounting screws and

bolts loosen, possibly with disastrous effect, but

vibration can also cause your fuel to foam, which will, in

turn, cause your engine to run hot or quit.We use a Top

Flite Precision Magnetic Prop Balancer (TOPQ5700) in

the workshop and keep a Great Planes Fingertip Prop

Balancer (GPMQ5000) in our flight box.

Engine Check

If the engine is new , follow the engine manufacturer’s

instructions to break-in the engine. After break-in,

confirm that the engine idles reliably, and maintains

full power–indefinitely. After you run the engine on

the model, inspect the model closely to make sure all

screws remained tight, the hinges are secure, the

prop is secure and all connectors are secure.

Control Check

With the lines connected to the leadouts and your

assistant holding the model, operate the controls to

make sure they move smoothly. If any binding or

hesitation is detected, inspect the model and

eliminate the problem.

This is where your model should balance for the first

flights.Later, you may wish to experiment b y shifting

the C.G.up to 3/8" [9.5 mm] forward or 3/8" [9.5 mm]

back to change the flying characteristics.Moving the

C.G. forward may improve the smoothness and

stability , but the model ma y then require more speed

for takeoff and make it more difficult to slow for

landing. Moving the C.G.aft makes the model more

maneuverable, but could also cause it to become

too difficult to control. In any case, start at the

recommended balance point and do not at any

time balance the model outside the specified range.

Adjust Leadouts

This model is equipped with adjustable leadouts.The

lines can be adjusted by means of a Phillips head set

screw located inside the slot provided for the leadouts .

The leadouts can be loosened, then slid fore and aft.

When they are in place, tighten the set screw down to

prevent the leadouts from moving back and forth in

flight. You should also check the leadouts after each

flight, making sure the screw is tight.

As a general guideline, positioning the leadouts

further aft makes the plane pull harder on the lines

(for windy days), b ut also mak es the plane “handle”or

react a little slower.This positioning is recommended

for less-powerful engines or longer lines and is also a

good way to counter the effect of having not enough

wing tip weight.

Further forward makes the plane pull less hard on

the lines, thus quickening response. This can be

better for calm days, and better for faster, more

powerful engines or shorter lines. It is also a way to

counter the effect of having too much wing tip w eight.

The exact placement of these leadouts will be a matter

of experimentation to match your flying style;however ,

we recommend centering the two leadouts in their

slots as a starting point.

ENGINE SAFETY PRECAUTIONS

• Keep all engine fuel in a safe place, awa y from high

heat, sparks or flames, as fuel is very flammable.

Do not smoke near the engine or fuel; and

remember that engine exhaust gives off a great

deal of deadly carbon monoxide.Therefore do not

run the engine in a closed room or garage.

• Get help from an experienced pilot when learning

to operate engines.

• Use safety glasses when starting or running engines.

• Do not run the engine in an area of loose gravel or

sand; the propeller may throw such material in

your face or eyes.

• Keep your face and body as well as all spectators

away from the plane of rotation of the propeller as

you start and run the engine.

• Keep these items away from the prop: loose

clothing, shirt sleeves, ties, scarfs, long hair or

loose objects such as pencils or screwdrivers that

may fall out of shirt or jacket pockets into the prop.

• Use a “chicken stick” or electric star ter to start the

engine. Do not use your fingers to flip the

propeller. Make certain the glow plug clip or

connector is secure so that it will not pop off or

otherwise get into the running propeller.

• Make all engine adjustments from behind the

rotating propeller.

• The engine gets hot! Do not touch it during or right

after operation. Make sure fuel lines are in good

condition so fuel will not leak onto a hot engine,

causing a fire.

• To stop a glow engine, cut off the fuel supply by

closing off the fuel line or following the engine

manufacturer’s recommendations. Do not use

hands, fingers or any other body part to try to stop

the engine. Do not throw anything into the propeller

of a running engine.

FLYING

Flying Precautions

Preflight

Note: The Top Flite Score ARF is not a beginner’s

model. It is intended for beginning to advanced stunt

pilots who have had some previous control line

experience. If you are an inexperienced pilot seek

the assistance of a knowledgeable control line pilot

who can help you with your first flights.

Beginning stunt pilots should make their first flights in

calm or low wind conditions. Stronger winds may

blow the model inward which will decrease line

tension resulting in loss of control.If the lines ever do

go slack, quickly step back to tighten the lines and

regain control. Of course, this is most likely to

happen, and should be expected, as the model

approaches the upwind half of the circle.

Study these flying safety precautions before

flying the Score ARF.

1. Always inspect your equipment before each

flight. Make certain the lines, leadouts and

handle are in good condition.Make sure there

are no kinks in the lines.

2. Fly only in unobstructed areas free from trees,

shrubs and bushes, poles, stakes, parking

barriers and fences.

3. Be aware of any spectators that may wander

into the flying circle. If this is a possibility,

have

your assistant ready to perform crowd control.

4. The model must NEVER be flown in the

vicinity of high-tension lines or any other

electrical lines.

5. Never fly when thunder storms or lightning

are present.

6. Take any precautions necessary to insure the

safety of spectators, the model and property.

7. Never touch the engine during or soon

after operation.

8. Keep clear of the rotating propeller and do

not let assistants or spectators get in the arc

of the propeller.

During the last few moments of preparation your

mind may be elsewhere anticipating the

excitement of the first flight. Because of this, you

may be more likely to overlook certain checks and

procedures that should be performed before the

model is flown. To help avoid this, a check list is

provided to make sure these important areas are

not overlooked. Many are covered in the

instruction manual, so where appropriate, refer to

the manual for complete instructions. Be sure to

check the items off as they are completed.

- 16 -

Place the model and starting equipment where the wind

will be behind the model when it is released for takeoff.

For the first half-circle (during the brief period when

the pilot has the least control before the model is “up

to speed”) the wind will push the model outward to

maintain line tension.

Mark the center of the flying circle with paint, chalk or

a suitable object (such as a shop towel) so you won’t

wander.This is especially important if the flying area

is limited.

With your assistant holding the model, walk from the

model toward the handle in the center of the circle

while using your fingers to keep the lines separated.

This will ensure that the lines are not twisted and are

free to operate the controls.

While the pilot is holding the lines, the assistant

should walk the model once around the circle to be

certain the flight path is clear and to double-check

that

there are no obstructions that could snag the lines.

The pilot should double-check the operation of the

controls by pulling and pushing on the handle and

having the assistant signal what the controls are

doing (“up” and “down”).

Takeoff

Note: A fully cowled engine may run at a higher

temperature than an un-cowled engine. Therefore,

the fuel mixture should be richened so the engine

runs at least 200 RPM below peak speed.By running

the engine slightly rich, you will help prevent dead-

stick landings caused by overheating. Traditionally,

control line pilots intentionally set their engines rich

so that during vertical maneuvers, the engine will not

“over lean,” thus causing overheating. Further, full

RPM is usually not desired for stunt flying.

When both the pilot and assistant are ready, the

model may be fueled and started.Once the engine is

running and the model is ready to be released, the

assistant should point the nose of the model slightly

away from the circle .This will help keep the lines taut

for the first few feet until the model gets going.

Upon the pilot’s signal, the assistant may release the

model–never push the model forward as doing so

may result in a crash.

The pilot should be ready–especially during

takeoff–to briefly step back to maintain line tension

until the model has gained enough air speed to

achieve line tension on its own. Allow the model to

roll out and gain enough speed to become airborne.

When enough speed has been gained the pilot may

raise his arm slightly giving “up” elevator command,

thus allowing the model to leave the ground.

Once the model has lifted, maintain a slow and steady

climb until a comfortable altitude has been

reached

(usually between “ey e-lev el”and

approximately ten feet

in the air). The lines must remain taut throughout the

entire flight. If the lines ever do go slack the pilot will

not have control of the model. During most situations

the model’s factory built-in features will allow it to

maintain good line tension, but on occasions when the

wind blows the model inward or the model becomes

too slow the modeler must anticipate or notice a

decrease in “pull”and quickly step backward to tighten

the lines and regain control.

- 17 -

To climb, the pilot will slowly raise his arm. To

descend, the pilot will slowly lower his arm. To

maintain level flight the pilot will hold his arm

horizontally .Beginning pilots should control the model

by keeping their arm straight and bending at the

elbow with little or no wrist movement. Later, when

they become more experienced, wrist movement ma y

be increased to increase control response.All control

inputs should be smooth.Continue flying the model in

a level attitude , getting used to ho w the controls react

and how the model “feels.” Do this until the engine

runs out of fuel. Actual flight time depends on several

factors, such as the engine size and brand, needle

valve setting, propeller size, fuel, atmospheric

conditions, etc.

Landing

When the engine starts to sputter and/or speed up, this

is an indication that the tank is nearly empty .Continue to

fly the model in a level attitude until the engine finally

quits.The same as any time the model slows, the pilot

should step back to keep the lines taut and maintain

control. Allow the model to descend until it is about two

feet off the ground.When the model has lost nearly all

flying speed and is a foot or two from the ground the pilot

should raise his arm to keep the lines taut and apply full

up elevator, allowing the model to gently touch down.

After the model has come to a stop the assistant may

retrieve the model and return it to the starting area.

In doing so the lines should be kept taut so they do

not become twisted or entangled.

Clean the model using paper towels and household

cleaner to wipe off exhaust residue. Inspect the

model thoroughly, looking for loose fasteners and

signs of damage or fatigue.Also make sure the prop

has not been damaged. Perform any maintenance

necessary to prepare the model for the next flight.

At the end of the flying session any residual fuel

should be drained from the tank.

After you have become familiar with the way your

Score flies and you are ready to begin performing

stunts, seek the assistance of an experienced stunt

pilot before attempting to learn new maneuvers on

your own. Almost any control line stunt maneuvers

are started with the model downwind from the pilot,

i.e.wind on the pilot’s bac k.Consult the AMA Control

Line section for stunt maneuvers.

One final note about flying your model.Have a goal or

flight plan in mind for every flight.This can be learning

a new maneuver(s), improving a maneuver(s) you

already know, or learning how the model behaves in

certain conditions (such as when testing different

propellers or fuel). This is not necessar ily to improve

your skills

(though it is never a bad idea!)

, but more

importantly so you do not surprise yourself by

impulsively attempting a maneuver and suddenly

finding that you’ve run out of time, altitude or airspeed.

Every maneuver should be deliberate, not impulsive.

For example, if you’re going to do a loop, check your

altitude and mind the wind direction. A flight plan

greatly reduces the chances of crashing your model

just because of poor planning and impulsive moves.

Remember to think!

Have a ball, keep the lines taut

and always fly in a safe manner.

GOOD LUCK, GREAT FLYING, AND HAVE FUN!
