FOR YOUR SAFETY - PLEASE READ AND UNDERSTAND THESE WARNINGS!

GENERAL WARNINGS

●

Do not fly your airplane if another airplane is on the same
frequency as you. The frequency number is printed on the
front of the radio transmitter.

●

Never fly your airplane from the street or at night.
Always fly in an open area free of obstructions.

●

When flying, make sure any spectators are behind you.

●

Always be conscious of the spinning propeller. Be careful
not to allow loose clothing to be drawn into the propeller.

●

Because your airplane is operated by radio control, it is
important to make sure you are always using fresh and/or
fully charged batteries. Never allow the batteries to run low
or you could lose control of the airplane.

●

Never attempt to disassemble any of the airplane's
components, especially the transmitter and flight battery.

●

Do not allow any of the components to get wet or
electrical damage may occur.

●

You should complete a successful range check of your
radio equipment prior to each new day of flying, or prior to
the first flight of a new or repaired airplane.

●

If your airplane gets dirty, do not use any solvents to clean
it. Solvents will damage the foam and plastic. Use a dry
cloth to clean any dirt from the outside of the airplane.

FLIGHT BATTERY WARNINGS

●

Never overcharge the flight battery or damage to the flight

battery may occur.

●

To prevent the flight battery from overheating during the
charging process, allow the flight battery to completely
cool before recharging it.

●

Always completely discharge the flight battery by running
the motor until it stops, before recharging the flight
battery.

RADIO SYSTEM WARNINGS

●

Always turn on the transmitter before turning on the
airplane and always turn off the airplane before turning off
the transmitter.

●

Always unplug the flight battery when not flying the
airplane.

●

Never cut the receiver antenna shorter or you could lose
control of the airplane during flight.

●

When flying the airplane, make sure the transmitter
antenna is completely extended.

PRO TIP

The Wattage Corsair EP Park Scale RTF includes a 7 cell Nickel Cadmium flight battery and a 2.5 hour AC
wall charger to charge the flight battery. If you want to, you can purchase a second flight battery so you have two. That
way, you can take two fully-charged flight batteries with you to fly. That means twice as much flying!

We also sell a high-performance quick-charger that can charge the flight
battery in about 30 minutes and is powered from your car's 12 volt DC
battery. This enables you to charge the flight battery at the flying field,
so you can fly as many times during the day as you want.

SECTION 3: BECOMING FAMILIAR WITH YOUR CORSAIR EP PARK SCALE RTF

Each Corsair EP Park Scale RTF comes with a sticker on the crystal mount showing which frequency in the 27Mhz band
that the radio control system operates on . No two airplanes can operate near each other if they are on the same frequency.

Antenna: Transmits the signal from the transmitter to the receiver inside the airplane.

Crystal Mount: This is where the transmitter's crystal is located. The radio's frequency is printed on the crystal mount.

Elevator/Rudder Control Stick: This stick can move both right and left, and up and down at the same time. The stick

moves the airplane's elevator and rudder which make the airplane climb, descend, turn right and turn left.

On/Off Switch: Turns the transmitter on and off.

Red LED: This LED glows red when the transmitter is turned on.

Servo Reversing Switches: These switches allow you to electronically change the direction the servos move.

Throttle Stick: Used to apply power to the motor. The stick is proportional, meaning that motor power can be applied

gradually from off to full power. This stick can also be moved right and left, but this feature is not used with this airplane.

Trim Tab: Used to electronically make minor trim adjustments to the control surfaces.

Voltage Scale: When the transmitter is turned on, the voltage scale displays the status of the transmitter batteries.

SECTION 5: LEARNING TO FLY YOUR CORSAIR EP PARK SCALE RTF

Step 1: Basic Operation

Before actually flying your Corsair EP Park Scale RTF you should understand how the airplane is controlled. Below we list
the four basic flight modes:

Climb: Climbing is controlled by pushing the throttle control stick on the transmitter (the left-hand stick) completely forward
to turn on the motor, then by pulling back on the elevator control stick (the right-hand stick). When you push forward on the
throttle control stick, the motor will turn on. When you pull back on the elevator control stick, the elevator will move up,
causing the airplane to pitch up and climb.

Descent: Descent is also controlled by the throttle and elevator control sticks. When you pull the throttle control stick all
the way back, the motor will turn off and the airplane will begin to slowly descend. To make the airplane descend faster, you
can also push forward on the elevator control stick. This will make the elevator move down, causing the airplane to pitch
down and descend.

Right Turn: A right turn is done by moving the rudder control stick (the right-hand stick) on the transmitter. This is the
same stick as the elevator control stick, only it moves right and left. When you move the stick to the right, the rudder moves
right, causing the airplane to bank and turn right.

Left Turn: A left turn is done by moving the rudder control stick on the transmitter to the left. When you move the stick to
the left, the left the rudder moves left, causing the airplane to bank and turn left.

Step 2: Ground Operations Testing

Now that you're familiar with the four basic flight modes, you can test the radio control system and the motor while seeing
first-hand how the different controls operate to make the airplane climb, descend, turn right and turn left.

PRO TIP

the motor. This will allow you enough time to become familiar with how the different controls react to the inputs from the
transmitter control sticks and it will prepare the flight battery for its first full recharge before flight.

❑ First, make sure that the on/off switch on the transmitter is in the "ON" position and that the flight battery is installed in

the fuselage and plugged in, and that the wing is installed. It should be if you've been following these instructions closely.

WARNING

You'll want to do Ground Operations Testing until the flight battery no longer has enough power to operate

Do not press the red motor arming switch yet.

❑ Carefully adjust the three control trim tabs on the

transmitter so that they are centered, as shown.

❑ Looking from the back of the airplane, push the

right-hand control stick completely to the left. The vertical
control surface (rudder) should move left.

❑ Again looking from the back of the airplane, push the

right-hand control stick completely to the right. The
rudder should move right.

❑ If the control surfaces are not exactly even with the

tail, unsnap the clevises and thread them in or out until the
control surfaces are even with the tail. After you're satisfied
with the alignment, snap them back into the outermost hole
in the control horns.

❑ Now, test the operation of the motor. Double-check that the throttle control stick is pulled completely back. While

keeping clear of the propeller, press the red motor safety arming switch of the left side of the fuselage once.

WARNING

❑ While holding the airplane upright in the air with the

propeller pointing away from you, push the throttle control

stick completely forward. The propeller will spin at a high rate
of speed.

❑ Continue the Ground Operations Testing until the flight

battery no longer has enough power to operate the motor. This
should give you enough time to become familiar with how the
airplane's controls operate. Once the flight battery no longer has enough power to operate the motor, remove the wing,
unplug and remove the flight battery, and turn off the transmitter.

SECTION 6: GETTING READY TO FLY YOUR CORSAIR EP PARK SCALE RTF

Step 1: Charging the Flight Battery

If the flight battery is hot to the

touch, it is fully charged. Unplug

it from the charger immediately.

❑ After completely charging the flight battery, install it into the fuselage, using the same techniques as when you installed

it previously.

WARNING

Step 2: Choosing a Day to Fly

❑ Until you become a proficient flyer you should always plan on flying your airplane when there's no wind. We strongly

suggest waiting for a calm day. If it's windy out and you attempt to fly, it will only make learning to fly the airplane more
difficult. Once you are proficient at flying the airplane, you can fly the airplane in light winds - no more than 10-15

miles per hour. Flying in stronger winds is not recommended.

Always remove the flight battery from the fuselage for the charging process.

❑ Plug the flight battery connector into the battery

charger connector. When plugged in properly you should
hear the connectors "click" together.

PRO TIP

only be plugged in one way.

❑ Plug the charger into a 110V AC wall outlet.

❑ Charge the flight battery for 2.5 hours. Be careful

not to overcharge the flight battery.

❑ To unplug the connectors, squeeze the tab on the

battery connector and pull the two connectors apart.

As a safety feature, the connectors can

❑ Tie the red flag to the end of the transmitter's antenna.

❑ Out at the flying field, before you fly, hold the

transmitter up at an angle. If the flag hangs down, go
ahead and fly. If the flag hangs at a 45º angle or more,
don't fly. Wait for a calmer day.

13

Step 3: Choosing Your Flying Field

❑ The flying field you choose should be a large, open field with grass. There should not be any vehicles, buildings,

power lines, trees, large rocks or anything else that your airplane can crash into.

Step 4: Range Testing the Radio System

After getting out to your flying field, but before you fly for the first time, you must range test the radio system. This will
ensure that the transmitter is "talking" correctly to the airplane. You should follow this procedure before every first flight of
the day and after you have a hard landing, crash, or after a repair.

❑ Turn on the transmitter, then plug in the flight battery and install it into the fuselage, then install the wing.
❑ Set the airplane on the ground and extend the transmitter's antenna completely. Move the right-hand control stick on

the transmitter several times to check the controls. They should operate smoothly.

❑ Walk approximately 75ft. from the airplane and move the right-hand control stick on the transmitter once more. Check

to make sure that the controls are operating smoothly at this distance. You may need a friend to help you with this step.

WARNING

If the airplane does not range check, don't fly! Please refer to the troubleshooting guide on page # 19.

SECTION 7: YOUR FIRST FLIGHT

After all this, I bet you're ready to actually go flying! If you've skipped anything prior to this section, we suggest going back
through the instructions. Doing so will help ensure your success.

WARNING

If at any time during your flight, the airplane gets stuck up in a tree, in power lines or on a roof top, DO NOT attempt
to retrieve the model yourself. The airplane is not worth the risk. We strongly suggest contacting your local fire

department for assistance. Attempting to retrieve the model yourself in any of these cases could potentially result in
extreme harm or even death.

Some Things to Remember:

●

With the flight battery fully charged, you can expect anywhere from 4-6 minutes of flight time, so plan your landing

accordingly.

●

Make sure that your flying field has no obstructions you can fly into.

WARNING

***

●

The flying field should be large enough that you can land anywhere if you get into trouble. Until you are proficient at

flying the airplane, you don't want to have to worry about landing in a small, localized area.

●

There should be no wind during your first few flights; also try to orientate yourself so you're not looking directly into the

sun while flying.

●

Fully charge the flight battery just before coming to the flying field. Do not charge the flight battery the night before, then

go flying the next day. The flight battery will have lost some charge and it won't produce full power.

14

Need help or have any questions? Call us at 1-714-963-0329 or send us an email to [e-mail]

●

Double-check that the elevator and rudder control surfaces are moving in the correct direction. If they aren't, flip the
servo reversing switches as described on page # 12. When you move the right-hand control stick forward and back, the
elevator control surface should move down and up. When you move the right-hand control stick right and left, the rudder
control surface should move right and left.

●

Double-check that the elevator and rudder control surfaces are centered and that the trim tabs on the transmitter are
centered, too.

Hand Launching the Corsair EP Park Scale RTF

●

With the transmitter turned on and the flight battery installed, carefully extend the transmitter antenna completely.

●

Double-check that the throttle control stick is pulled completely back, then press the red motor arming switch on the
fuselage once.

●

Carefully grasp the fuselage with your thumb and forefingers right behind the wing. While holding the transmitter in your
other hand, push the throttle control stick forward to check that the motor powers up. Now, pull the stick completely back.

●

If there is any wind, turn to face it. While holding the throttle control stick completely forward (the propeller will spin very
fast), hold the airplane just above shoulder level and gently toss the airplane straight ahead and level. Allow the airplane
to fly straight and continue to hold the throttle control stick completely forward so that the airplane climbs.

PRO TIP

If the airplane begins losing altitude after launching, pull back gently (only a small amount) on the

right-hand control stick. This will cause the airplane to gently pitch up and climb.

●

After you've launched the airplane, keep the motor running and allow the airplane to continue to climb. After reaching
about 80 - 100 feet of altitude you should start making shallow turns, moving the right-hand control stick right or left, to keep
the airplane near you.

PRO TIP

We recommend trying to keep the airplane near you while flying. The airplane is small, so if it gets too far
away, it will be difficult for you to see. This will make it more difficult to learn to fly the airplane and could result in
complete visual loss of the airplane.

Flying the Corsair EP Park Scale RTF in the Air

●

Now that the airplane has climbed to a safe altitude you can begin to learn the basics of flight. General flying should be
done with the motor at full power. You control the altitude of the airplane by either moving the right-hand control stick
forward or back. Moving the stick forward will cause the airplane to pitch down and lose altitude, and moving the control
stick back will cause the airplane to pitch up and gain altitude. These control inputs should be done gently, so you don't
overcontrol the airplane.

PRO TIP

When the airplane climbs you will notice that it will begin to lose speed. You'll also notice that the airplane
will gain speed when the airplane descends. If you climb too steeply, the airplane may slow down so much that it stops
flying and "stalls." Conversely, if you descend too steeply, the airplane may fly so fast that you begin to lose control. For
these reasons, we suggest using small, gentle control inputs to prevent this from happening.

●

To turn the airplane, you need to move the right-hand control stick in the direction you want the airplane to turn, either
right or left. To make smooth, gentle turns, gently move the control stick in the direction you want the airplane to turn and
HOLD the stick in that position for a second or two and the airplane will begin to turn. After the airplane has turned in the
direction you want, allow the control stick to return to center.

PRO TIP

The longer you hold the control stick over, the tighter radius the airplane will turn in. We recommend gentle

turns until you are proficient with the flight characteristics of the airplane.

●

When going into a turn, the airplane will have a natural tendency to lose some altitude. Unless you want to descend, you
should gently pull back on the right-hand control stick to keep the airplane level during the turn. The steeper the turn the
more altitude the airplane will lose and the more you will need to pull back on the control stick.

●

You should continue to fly, making circles and S-turns for about 3 minutes or so. This will give you plenty of time for
landing. Remember for now to keep the motor at full power and use gentle control inputs to keep the airplane level
throughout the entire flight. Also remember to keep in mind that when you make turns the airplane will want to lose altitude,
so you'll need to pull back gently on the control stick to keep the airplane level.

PRO TIP

down and climb steeper. When this happens, gently move the control stick forward to pitch the airplane down if you don't
want the airplane to climb. When the airplane turns down-wind (with the wind), it will speed up and descend. You should
gently pull back on the control stick to keep the airplane from descending too much while flying down-wind.

●

After some practice, you will learn how to minimize the amount of up and down, and right and left movements of the
airplane and be able to control the airplane in a smooth and graceful manner.

Landing the Corsair EP Park Scale RTF

●

Landing should always be done into the wind with the wing level.

●

To prepare for landing from normal flight, make a shallow turn so that the airplane is flying directly into the wind. Make
small turns to level the wing, then pull back completely on the throttle control stick to turn off the motor. When you do this,
the airplane will gradually descend straight ahead.

●

Allow the airplane to gradually descend. If the airplane seems to be descending too fast, gently pull back on the
right-hand control stick to make the airplane pitch up to level flight. This will bleed off speed and slow the descent. Once
the airplane has slowed down, release the control stick and allow the airplane to continue its descent. Once the airplane
is about 15 feet off the ground, make sure that the wing is level and continue a shallow descent. Just before touch-down,
gently pull back on the right-hand control stick to level the airplane with the ground for landing.

PRO TIP

turns may cause the airplane to stall and crash. Also, you should just try to land anywhere on your flying field, as long as
it's into the wind. Don't try to land in a particular spot. You can do that once you've mastered flying the airplane.

If there is any wind when you are flying, you will notice that when the airplane turns into the wind it will slow

If you need to turn the airplane while descending for landing, make gentle, shallow turns. Making steep

Now that you've made your first few successful

flights, congratulations! Now you may want to

trim your airplane to fly even better. That's

done in the next section.

SECTION 8: FLIGHT-TRIMMING THE CORSAIR EP PARK SCALE RTF

If you're flying the airplane and it seems to always want to turn right or left or pitch up or down, you can use the electronic
trim tabs on the transmitter to correct these tendencies. We suggest flying the airplane straight ahead and level, then let
go of the right-hand control stick for a few seconds. Watch what the airplane does. It may pitch up or down, or it may turn
right or left, or it may do a combination of these. Do this several times to double-check your findings. If the airplane does
one of the following while in straight and level flight without your hand on the control stick, move the following electronic trim
tab(s) to correct it:

●

If the airplane pitches up: Move the right-hand control stick vertical trim tab forward a couple of clicks.

●

If the airplane pitches down: Move the right-hand control stick vertical trim tab back a couple of clicks.

●

If the airplane turns right: Move the right-hand control stick horizontal trim tab left a couple of clicks.

●

If the airplane turns left: Move the right-hand control stick horizontal trim tab right a couple of clicks.

You can make these trim tab changes while you are flying, but we suggest having a friend move them for you so you don't
lose sight of the airplane. We also recommend moving the trim tabs a couple of clicks at a time so you don't over-correct
for the trim problem.

SECTION 9: FIXING MINOR CRASH DAMAGE

While you are learning to fly, there comes a time when you might crash. If the crash isn't too bad, most damage can be
repaired quickly and easily. If the damage is beyond repair, spare parts are available for purchase. If a foam part is going
to break during a crash it will usually break cleanly. To repair a clean break, follow the procedures below:

❑ Glue the broken parts together using a thin layer of 5 minute epoxy or white glue, following the directions on the glue

bottle. Hold the parts together and in alignment until the glue fully cures.

❑ Apply a strip of clear Scotch

WARNING

It is very important that you use no solvents or Cyanoacrylate (C/A) glue, which can damage foam. If

®

tape over the seams to strengthen the joint even more.

any of these chemicals comes in contact with the foam parts, the parts will be destroyed. Use only epoxy or white glue
to repair damaged foam parts.

SECTION 11: FLIGHT TIPS AND WARNINGS

●

Check before every flight to ensure that the batteries in the transmitter are working properly. The needle in the voltage

meter should be in the green "safe" area. Change the batteries when the needle falls into the red "unsafe" area.

●

Before recharging the flight battery, let the motor run until the flight battery is completely drained. This will ensure you

don't overcharge the battery.

●

Do not recharge the flight battery if it is hot. Wait for the flight battery to cool before recharging it.

●

Never leave the flight battery plugged into the airplane unless you are flying or testing the controls.

●

Before flying, always double-check that you've extended the transmitter antenna completely.

●

Never cut or otherwise shorten the receiver antenna or you will lose control of the airplane in a very short distance. Let

it hang behind the back of the fuselage.

●

Before each flight, do a quick motor test to make sure that the motor is producing full power. If it isn't, you may need
to charge the flight battery longer. Do not charge a completely drained flight battery longer than 3 hours or damage to the
flight battery may occur.

●

Before each flight, double-check that the control surfaces are moving in the correct direction. If they aren't, adjust the
servo reversing switches on the transmitter as described on page # 12.

●

When you fly, orientate yourself so that the sun is at your back. Don't fly directly into the sun or you may lose sight of
the airplane.

●

Separate flight batteries can be purchased and charged before going to the flying field. An extra flight battery will
double your flight time. See the replacement parts list on page # 17 for the part number of the flight battery.

●

Do not fly in winds over 10-15 miles per hour, or the airplane will be very difficult to control and a crash might occur.

●

Do not fly your airplane if another airplane is on the same frequency as you. The frequency number is printed on front
of the crystal mount on the transmitter.

●

Always be conscious of the spinning propeller. Be careful not to allow loose clothing to be drawn into the propeller.

●

If you're under 12 years of age we suggest you fly while accompanied by an adult.

●

Never attempt to disassemble any of the airplane's components, especially the transmitter, charger and flight battery.

●

Do not allow any of the electrical components to get wet or damage may occur.

●

The propeller is a friction fit to the motor shaft. Sometimes the propeller may be knocked loose during a crash or it may
become loose from taking it off. If this is the case, simply apply a thin layer of Elmers

®

White Glue to the motor shaft

before installing the propeller. This will help keep it firmly in place. Be careful not to get glue inside the motor.
