Helpful Hints
• Flight time is about 7-15 minutes. When the battery on the plane
is low, the motor will shut off; however, the servos will still work,
so you can land the plane. Land the plane as soon as possible when
the power runs out.
• Check the direction and speed of the wind before you begin to fly.
• Check the power light on the transmitter before and after a flight. If
the green light becomes dark or goes out, do not fly the plane until
the transmitter batteries are replaced
• Purchase an extra 8.4v battery pack for longer flying times.
• 8 AA alkaline or NiMH batteries are recommended.
• Always stay far away from trees, buildings and elevated land.
Unexpected air currents can quickly alter your Freedom Flyer’s
course and possibly lead to an accident.

Assembling Your New Freedom Flyer
Items Required to Complete Your Freedom Flyer:
• 8 AA alkaline batteries
• Transparent tape
• Felt-tip marker
• Small Phillip’s Head screwdriver
Step 1: Assemble the Landing Gear
Grasp the legs of the main landing gear. Gently squeeze the legs
together, and then push the gear into the slot on the bottom of the
fuselage. See Figure 2.
Press firmly, but gently,
until it is in all the way.
Then release the pressure
on the gear legs and give
them a gentle tug to make
sure they are secure. To
remove the main gear,
simply squeeze the gear
legs together to release the
gear from the housing and
pull it out of the slot.
Figure 2 - Squeeze legs until gear fits into slot.

Assembling the Freedom Flyer
Safety Warnings
The spinning propeller on this aircraft can be dangerous
and should be treated with respect and caution! Use
extreme care when operating your airplane. Keep your hands,
fingers and any article of clothing away from the propeller.
Step 2: Assemble the Tail Surfaces
Locate the horizontal stabilizer from your kit. Remove the tape backing
and carefully slide the horizontal stabilizer into the slot located at the rear
of the fuselage as shown in Figure 3. The elevator control horn should be
pointing upward. Route the antenna under the horizontal stabilizer, so it
exits from the indentation in the rear of the fuselage. Make certain that the
stabilizer is perfectly level and 90 degrees to the vertical fin as indicated in
the picture. When the horizontal stabilizer is properly aligned, use a small

Figure 3 - Push horizontal stabilizer (tail) in from the rear.
Phillip’s head screwdriver and insert the screws into the pre-drilled
holes in the tail as shown in Figure 3. Be careful not to over-tighten
the screws.
Next, snap the plastic control links into place. The clevis (hook) at
the end of the push rod on the left side of the plane (when held nose
down) attaches to the horn on the rudder. The clevis on the right
connects to the elevator control horn. Don’t worry if the rudder and
elevator are not straight. They will be adjusted later.
Step 3: Attach the Propeller
Find the propeller with built-in nose
cone. Firmly, but carefully, press it onto
the prop shaft at the nose of the plane
as shown in Figure 4.
Figure 4 - Gently push nose cone
onto propeller shaft.
Step 4: Attach the Wing to the
Fuselage
A.
Set the wing on the fuselage.
Carefully align the center of the
wing onto the saddle area of the
fuselage. Look at the picture on
the box if you’re not sure what is
the front and what is the back of
the wing.
Alignment Marks
Figure 5 - Attaching the Main Wing
B.
Important Note!
Always remove the wing from the fuselage when not
flying. This will help reduce the chance of
accidental damage.

The Radio System
C.
Find the four wing bands. Hook the first wing band over the
left rear post on the fuselage, then run it diagonally across the
wing and secure it to the right front post. Now repeat on the
other side. Right rear post to left front post. Then run a third
wing band from the left front to the left rear post and next run
a band from right front to right rear. See Figure 5.
After the wing bands are installed, check the wing once again
to make certain that it is still perfectly centered. When
perfectly centered, make an alignment mark (use a pencil
or felt-tip marker) at the front and rear of the wing where it
meets the fuselage. The marks will make it easier to align the
main wing next time you install it.
The Freedom Flyer Radio System
This aircraft includes a 4-channel R/C
(radio control) system although only 3
channels are actually used . See Figure 6.
The stick on the left side of the
transmitter operates the motor. When
this stick is all the way in the “down”
position, the motor is off. For added
safety, power won’t turn on until
after the stick is moved at least
halfway up. Then power increases as
the stick is moved up. Full power is
reached when the left stick is
positioned fully “up”. The right stick
Figure 6 - The Radio Transmitter
controls the elevator (up and down)
function and the rudder (right and
left) function.
There are two battery LED lights located at the center top of the
transmitter face. When both the Red and Green lights are lit, you have
adequate power to control your aircraft. If only the Red light is lit, the
transmitter batteries are low and must be replaced. Never attempt to fly
when only the red LED light is lit! This will result in loss of control and
most likely a crash! The radio system is tuned to a specific frequency
channel in the 27 MHz or 72MHz band. The crystals in both the transmitter
The Battery Pack
8
and receiver may NOT be changed. Attempting to do so is a violation
of FCC (Federal Communications Commission) law and will render
your radio unusable! Contact our service center if you think there
may be a problem with your radio or should you need to change the
frequency. There is an auto-shutoff feature in the aircraft that allows
both the radio system and the motor to be powered from the same
battery pack. When the battery pack starts to run low, it will
automatically shut off the motor, while leaving enough reserve
power for the radio (about 3-4 minutes) to control the servos and
glide in for a safe landing. Land the plane as soon as possible when
the power runs out.
NOTE: The four switches at the
bottom right of the transmitter are
Servo Reversers. They enable this
transmitter to work with other RC
Aircraft. They are factory preset to the
correct position.
Figure 7 - Servo Reversers
The Battery Pack
The battery pack included with the Freedom Flyer (see Figure 8) is made
up of NiMH (nickel-metal-hydride) rechargeable cells. These are very
different from regular dry cell batteries! With proper care and charging
methods, these packs can be charged and used hundreds of times before
they need to be replaced.
Important: The Freedom Flyer uses a special battery with polarized
connectors. Do not use any battery pack for this aircraft other than
original Megatech™ equipment. Use of any other battery pack may
cause damage to the aircraft and void your warranty!
The Battery Charger
The battery charger (see Figure 8) is
designed specifically for the battery
packs in your Freedom Flyer and will
not charge any other type of battery pack.
Attempting to charge a battery other than
the type included with this airplane will
result in damage to both the charger and
the battery.
Figure 8 - Battery Pack and Charger
CAUTION
9
Charging the Battery
It is normal for NiMH battery
packs to become warm during
the charging process. You can
also expect the battery pack to be
warm after each flight. Always
allow a warm battery to cool prior
to recharging, and never attempt
to charge a battery pack that is
Figure 9 - Battery Connectors
too warm to hold in your hand.
Always disconnect the charger from the electric socket when the
charging process is complete. When connecting or unplugging the
battery pack, hold it by the connectors. Never pull on the wires. (See
Figure 9)
READ THIS SECTION BEFORE CHARGING YOUR
BATTERY PACK FOR THE FIRST TIME!
● Always handle the battery pack carefully.
● Never cut the battery lead wires.
● Do not insert any metal objects into the battery plug, as a direct
short (and quite possibly a fire) will result.
● Always remove the battery pack from your Freedom Flyer after each
flight. Do not store the battery pack inside the aircraft.
● Never allow the battery pack to get wet. Should the battery ever come
into contact with any moisture, dry it carefully before attempting to use
it again. Moisture can cause short-circuits and severe damage.
● Keep the battery away from heat or fire. Never leave the battery pack
in direct sunlight.
● Never leave the battery pack unattended while charging. Over-charging
can damage your battery.
● Always remove battery from airplane before charging.
● Dispose of NiMH (nickel-metal-hydride) batteries properly. Never
place them in a fire!
Charging the Battery
A. Plug the charger into an electric socket.
B. Next attach your battery pack to the battery charger. The charger will
automatically begin charging the battery pack.
C. Charging will take approximately 2 hours, however, longer charge
times may be necessary when the battery is new. Charging is complete
when the battery is warm to the touch. Do not allow the battery to get
too hot.
10
Installing & Cycling the Batteries
Installing the Batteries
A. Be sure that both the transmitter and
receiver switches are in the “off”
position.
B. Install 8 fresh AA alkaline batteries
in the transmitter (see Figure10). Turn the
transmitter on to make sure both LED
Figure 10 - Radio Batteries
lights glow. Fresh batteries will provide
about 2 hours of power to the transmitter. When the LED light glows
red, immediately install fresh batteries. Failure to do so will result in
loss of control and (most likely) a crash.
C. Charge the on-board battery
pack as previously instructed on
page 9.
Connect the charged battery as
shown in Figure 11. Carefully
install the battery between the
foam braces, neatly folding the
wires on top of the pack. Once the
battery is inserted into the aircraft,
Figure 11 - Radio Batteries
the wing may be attached to the
aircraft.
Cycling the Batteries
AFTER READING THIS ENTIRE MANUAL, BUT BEFORE YOU
FLY YOUR FREEDOM FLYER FOR THE FIRST TIME:
You must “cycle” the battery pack at least twice prior to flying your
aircraft. This will provide the aircraft with more power and longer flight
times!
Here’s how: Switch on the transmitter first. Charge the battery pack as
instructed earlier and then install the charged battery into the aircraft.
Carefully hold the airplane at the center of the fuselage so the propeller arc
is unobstructed and away from fingers, loose clothing, etc. Press the red
arming button and move the throttle stick to full. Allow the motor to run
until it stops. Allow the battery pack to cool, and then recharge. Repeat the
process of running the motor until the battery is drained. The battery pack
will now supply more power and your first flights will be much easier and
safer!
11
Safety Start Switch
Preparing to Fly
Preparing to Fly
You’ll notice a red button located on the
side of the fuselage beneath the wing. This
button must be pressed before power can be
supplied to the motor. This safety start
switch exists so that radio interference or
problems can be discovered without the
motor starting unexpectedly. See Figure 12.
NOTE: Always turn the transmitter on first,
before turning on the receiver. Only push
the red safety start switch after you are
certain that the radio is operating properly Figure 12 - Safety Start
Switch
and you’re ready to fly!
A. Set the transmitter trim adjustment levers (located beside and
below the stick assemblies) to their center positions. Make sure the
throttle stick is in the “down” position! Turn on the transmitter.
DO NOT PUSH THE SAFETY START BUTTON AT THIS
TIME! Adjust the control links (clevis) at the end of the elevator
and rudder pushrods, so that when inserted into the control horns,
both the control surfaces are level
(neutral) as shown in Figures 13A,
13B and 13C.
13C Turn the clevis
clockwise to shorten it and counterclockwise to lengthen it.

B. At this time, move the rudder and elevator control stick (the right control stick), to see how the controls operate your Freedom Flyer. Notice
that you can operate the rudder and elevator at the same time. This helps
provide smooth, controlled flights. See Figure 14 for reference.

Figure 14 - Control Stick Movements
By moving the stick diagonally, you can turn the plane and change
altitude at the same time. The control stick is proportional, so if the
movement of the stick is more to the right than down, for example, the
plane will bank strongly to the right, but ascend gradually or hold
altitude. When the plane banks left or right, the nose will tend to drop,
so a little up elevator will tend to keep the plane from dropping.
IMPORTANT:
Always turn on the transmitter first (before installing the
battery).
Always unplug the battery first (before turning off the
transmitter).
Your airplane runs
forward at variable
speeds.
Move the stick up to turn
the motor on and the
propeller starts turning.
The more you move the
stick up, the faster the
motor will run. Move the
stick fully up for maximum
speed.
When the motor
stops running, the
plane glides.
Safety Precautions
C. Next test the motor (this should be done outdoors!). First, make
certain that the left stick, the throttle stick, is in the “off” position (all the way down) and the transmitter switch is on. Then
firmly grasp the center of the Freedom Flyer fuselage, keeping
hands and all obstructions clear of the propeller. Now press the
red safety start switch and slowly move the throttle up to full to
make certain the propeller and gearbox are operating properly.
Move the throttle up and down a few times to get a feel for how
it works (See Figure 15). Once you are satisfied and familiar
with the operation of your Freedom Flyer, unplug the battery and
then turn off the transmitter.
13
Move the stick fully
down to turn the
motor OFF and the
propeller will stop
turning.
Figure 15 - Throttle Stick Movements
IMPORTANT SAFETY PRECAUTIONS
Please read these before operating your Freedom Flyer.
● You alone are responsible for operating your aircraft in a safe and
responsible manner. Follow these basic safety guidelines at all times.
● Always fly your airplane in a wide-open area. You’ll need at least
two football fields worth of area that is free from obstructions such as
buildings, electric power lines, trees, roads, other people or vehicles.
Do not fly around people who are unaware that you are flying a model
airplane, and never fly over people’s heads.
● Fly only on calm days. Gusty winds and winds over 10 mph will make
it difficult (if not impossible) to control the aircraft properly.
Pre-Flight Preparations
14
● Make sure that the transmitter and receiver are both switched off
and the battery is disconnected when you are not flying.
● Do not attempt to disassemble any of the airplane’s components or
allow them to get wet. Electrical damage may occur.
● Never fly your airplane from roadways or after dark.
● When operating/flying, always be aware of the spinning propeller.
Be careful not to let it come close to your body, other people or
loose clothing.
● Keep spectators behind you when flying.
● Since your airplane is controlled by a radio link, it is very
important to always use fresh alkaline batteries in the transmitter.
We recommend Megatech’s Golden Power series, designed for
R/C products.
● Before flying, make sure you perform a range check and can
maintain control at least 25 feet from transmitter to model with the
transmitter antenna collapsed. Do not fly your airplane if
other models are being operated on the same frequency in the area.
If you are at a field with other pilots, NEVER TURN ON YOUR
TRANSMITTER OR RECEIVER without first confirming that
there are no other models in the air on the same radio frequency.
Talk to the other pilots and make sure that they are aware of what
frequency you are using.
● Do not use solvents or liquid cleaners to clean this model. Doing
so may damage the plane. Use a dry, soft cloth for cleaning.
Pre-Flight Preparations
Now it’s time to describe how you can become a successful R/C pilot with
the Freedom Flyer. A little patience and care exhibited here will result in a
well-flying, long-lasting aircraft.
Did you “cycle” the battery pack as previously described on page 10? This
is extremely important!
Perform these pre-flight checks each time you fly:
● Is the wing properly aligned and attached securely to the fuselage?
● Are both transmitter LED lights glowing?
● Is the transmitter switched on prior to installing the battery pack?
● Do the rudder and elevator controls work properly after turning on the
transmitter?
Your First Powered Flight
Launching By Hand
1) Face directly into the wind.
2) Turn on the transmitter first, and then install the battery.
3) Grip the aircraft underneath the fuselage and slightly
behind the wing. Press the red safety start button.
4) Move the throttle stick up to full power.
5) Take 4 or 5 running steps, keeping the wings as level as possible
with the aircraft pointed into the wind. You’ll feel the airplane
actually try to rise up out of your hand.
6) Give the plane a firm, level push forward as you run (in a
smooth motion). Do not throw the airplane! Release the
airplane straight and level with the ground. Do not release it
with the nose pointed upward. The plane will begin to climb
upon release. See Figure 16.
Figure 16 - Hand Launch
Your First Flight
We recommend that while learning, you launch your Freedom Flyer
by hand. Although capable of taking off from the ground, there are
several
disadvantages to attempting this. Ground take offs provide no margin
for error. After breaking ground, you simply do not have enough time
to react to sudden changes in pitch or altitude. With a hand launch,
the Freedom Flyer will basically “fly out of your hand,” providing
several feet of altitude for the airplane to stabilize prior to needing
any control inputs. This gives you a few precious seconds to catch
your breath and begin controlling the aircraft. We strongly recommend using only hand-launch take offs when learning to fly the
Freedom Flyer.
15
Turning Your Plane
16
Control Stick Adjustments
Keep your stick movements smooth, not abrupt or “jerky”. The
aircraft will actually fly all by itself if left alone, and SMALL movements of the stick are all that you need to control your plane. In fact,
moving the rudder/elevator stick all the way in any direction will
cause the aircraft to become unstable, so remember……smooth!
After launch, allow the aircraft to fly directly away from you and
gain altitude prior to making your first turn. If the aircraft turns,
climbs or dives with no control input, correct the flight path by gently moving the stick in the appropriate direction. See Figure17.

Figure 17- Adjusting the Trim In Flight
Turning Your Freedom Flyer
Turning the Freedom Flyer is done with the coordinated use of both
rudder and elevator controls. The rudder makes the aircraft yaw (bank)
in the direction you wish to turn. When the aircraft banks, the nose will
naturally drop, so small amounts of up elevator will be needed to keep the
aircraft at a constant altitude while turning. As the aircraft turns to the new
heading that you desire, a small application of opposite rudder will level
the wings and return the aircraft to straight and level flight.
Start the turn by feeding in a small amount of rudder in the direction you
wish to turn. As the airplane turns and the nose drops, gently feed in just
enough up elevator to keep the nose level. Bring the rudder back to neutral
as the aircraft completes the turn. When on the desired heading, feed in
just a bit of opposite rudder to level the wings and return the elevator to
neutral to keep the aircraft from climbing excessively.
Your first flights will be easier if you face the same direction your aircraft is flying. This way, you can always orient yourself as if you’re in the
pilot’s seat, even if it means looking back over your shoulder at the plane.
NOTE: if the airplane is flying directly at you, the rudder control direction
is “reversed”. This means that right stick results in a turn toward your left
After you become experienced
at turning around by making
two 90-degree turns as
described earlier, you can
try turning in one smooth
continuous motion as shown
here. Remember that turning
a plane requires a coordinated
movement of both rudder and
elevator. Use the rudder control
to bank the plane into the turn,
and use the elevator control to
maintain altitude.
Practice, practice, practice!

Figure 18B - Flying Pattern
Fly an oval pattern in front of you as shown here on the left. Flying in a
continuous circle or flying around you as pictured on the right will lead to
disorientation and will most likely cause you to crash.
Adjusting the Trim
For your first flights, you’ll find it easier to turn by making two 90degree turns instead of one 180-degree turn. Turn 90 degrees, fly straight
for awhile and then make another 90-degree turn. Do not attempt to make
a complete circle, as it’s easy to become disoriented. See Figures 18A and
18B.

when the aircraft is flying toward you. Turning with the plane and
always facing the same direction will greatly help you learn how to
fly in a shorter period of time.
During the first flight, execute gentle climbing circles in front of you.
Keeping the aircraft in front of you (not overhead) is very important
and crucial to successful first flights. Fly the airplane at a comfortable altitude and wait for the motor to cut off. Always think about
where you want the airplane to go next. Anticipate where you want
the aircraft to be prior to bringing the aircraft in for a safe landing.
Having trouble?
Should you over-control your airplane or lose orientation, it’s possible that you’ll find yourself in a downward spiral dive. Should this
occur, remain calm and simply release the sticks! The plane will stop
turning by itself, and will exit the spiral dive with the nose pointed
down. Feed in some up elevator to level the aircraft and climb to a
safe altitude.
If you see that you’re going to crash, immediately cut the power.
Doing so will minimize the damage to the aircraft.
Landing Your Freedom Flyer
Circle the airplane
gradually into the
direction of the wind.
Note:
When the
motor shuts off,
slide the motor control
stick down to the off position.
This will prevent the motor
from unexpectedly coming
back on.
Landing Your Plane
When the motor stops, the nose will drop slightly. This is normal
under reduced or zero power. Do not immediately give up elevator!
Use the rudder to steer the aircraft toward a landing pattern. (See
Figure 19)
19
If the airplane is too low, a
downwind landing may be
required.
Figure 19 - Landing Your Aircraft
Always set up landings into the wind, and use very small amounts of up
elevator during turns. You should keep the nose of the plane in a gentle
dive to maintain forward airspeed when the motor is off. At an altitude of
about 3 feet, gently pull back on the elevator to “flare” the aircraft (point
the nose slightly upward) before touchdown.
If you’re too far away to land safely on the desired landing area, don’t
panic! Simply land the plane smoothly into the wind. You will not damage
the aircraft as long as you take care to land gently!
Taking Off From The Ground
The Freedom Flyer is capable of taking off from the ground. Keep in mind
that ROG (rise off the ground) take-offs use up some battery power and
will shorten your flight time.
The most important thing to remember about lifting off from the ground is
to gently apply up elevator after the airplane has reached sufficient flying
speed. Excessive elevator input will cause the aircraft to stall and fall out
of the air, as will trying to lift off before sufficient airspeed is built up.
Repairing your Freedom Flyer
20
Begin by placing the airplane on a smooth asphalt or concrete surface. Push the aircraft by the vertical fin and watch to make sure that
it rolls straight. If the airplane pulls to the right or left, adjust the
nose wheel so that it rolls straight down the runway. Once the aircraft rolls straight, line it up on the runway that you’ll be using and
you’re ready to attempt a ground take off.
Switch on the motor and advance the throttle to full power. Keep the
airplane travelling in a straight path by using small rudder inputs if
necessary. Allow it to pick up speed for about 35 feet, then gently
add a small amount of up elevator and the Freedom Flyer will break
ground. Continue to gain altitude in a shallow climb and you’re on
your way. See Figure 20.

Making Repairs
If the wings or tail surfaces should
crack or break, they can be repaired
using 5-minute epoxy glue. If the
crack is small, the part can also be
fixed using a strong clear packaging
tape. See Figure 21.

When it is time to replace the propeller, firmly, but carefully, pull
the current propeller and nosecone off. Then, slide the new
nosecone and propeller into place.
