Important! You alone are responsible for operating your model in a safe manner. Before you begin,
please read all safety precautions and warnings. Failure to comply with any of the following could
lead to bodily harm or injury to you or others. The Megatech Prowler is not intended for those
under 14 years of age without proper adult supervision.
SAFETY PRECAUTIONS
TRANSMITTER SAFETY
This device complies with part 15 of FCC rules.
Operation subject to the following two conditions:
1) This device may not cause harmful interference and
2) This device must accept any interference received, Including interference that may cause
undesired operation.
• Since your model is controlled by a radio link it is very important to always keep fresh alkaline
batteries in the transmitter.
• The transmitter should always be the FIRST thing you turn on - and the LAST thing you turn o.
• The transmitter’s antenna must be fully extended for optimum radio range during ight.
• Do not trim the airplane’s antenna. It is cut to a specic frequency length. Doing so will
drastically aect radio range.
• Always use gentle control stick movements to y your plane.
SAFETY GUIDELINES
• Look at the frequency label on the front of your transmitter. Do not y your airplane if other
models are being operated on the same frequency nearby.
• Do not tamper with the electrical componenets or allow them to get wet. Electrical damage may
occur.
• Never y your Prowler from roadways or after dark.
• Always y your airplane in a wide open area (at least 300 ft), free from wires, trees and other
obstructions.
• When operating/ying, 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 ying. Do not y around people who are unaware that you are
ying a model airplane.
• Before ying, make sure you perform a range check. You should be able to maintain control at
least 100 feet from transmitter to plane with the transmitter antenna extended.
• Do not use solvents or liquid cleaners to clean this model. Use a dry, soft cloth for cleaning.
• Keep the Prowler away from heat or re. Never leave the
RECHARGEABLE BATTERY WARNINGS AND PRECAUTIONS
• ALLOW THE FLIGHT PACK TO COOL COMPLETELY AFTER EACH FLIGHT BEFORE ATTEMPTING TO
CHARGE, DISCHARGE OR FLY.
• NEVER LEAVE THE FLIGHT PACK UNATTENDED WHILE CHARGING.
• Only charge the ight pack until it becomes warm. Do not let it get too hot. This should take
approximately 30 minutes using the DC charger or about three hours using the AC Charger.
• Never place a charging battery on your car seats or console, but rather outside the vehicle on a
ame & heat resistant material (such as an oven mitt).
• Always remove the ight pack from the Prowler when not in use.
Nickel-metal hydride batteries must be disposed of properly. For current
regulations in your area and proper disposal sites please call 1-800-822-8837 or visit

THE RADIO SYSTEM
The 4-Channel radio system included with your Prowler can be used in other radio control
airplanes should you wish to do so.
NOTE: The Prowler is a 3-channel airplane. As such, this manual refers to the control sticks by the
functions they apply to on your airplane. The control referred to in this manual as “Rudder” is actually
the “Aileron” control. If you were to use this radio system in a full 4-channel airplane, the left stick
would be controlling your Throttle (Up/Down) and Rudder (Left/Right), while your right stick would
be controlling your Elevator (Up/Down) and Aileron (Left/Right). The servo reversing switches and
beginner mode adjustment dials use the proper 4-channel naming convention.
Your transmitter has a function known as servo reversing. There are four switches located at
bottom right of the front panel on the transmitter to reverse the directional throw of the servos
for each of the 4 channels. Starting from the left, the rst switch is for Ailerons. The second
switch is for Elevator. The third switch is for Throttle and the fourth switch is for Rudder. These
switches should already be set to the proper positions for your
Prowler. If they are not, set them as shown above.
Your transmitter also has a Beginner/Expert function. It allows you
to change how much servo response you get from the movement
of your transmitter control stick. When the Beginner/Expert
switch on top of your transmitter (see image to right)is set to the
“Beginner” setting, you can use the Beginner Mode Adjustment
Dials above the servo reversing switches to adjust how much
response each control has. Turning the dial clockwise gives that
control more response, counter-clockwise gives it less.
NOTE: We do not recommend adjusting the throttle control response. If you are a beginner pilot we
recommend using the beginner setting until you get used to the control inputs.

INSTALLING THE BATTERIES
Caution: Never mix old and new
batteries. Only use fresh alkaline (non-
rechargeable) batteries in the transmitter
to assure best radio signal link. The
transmitter requires 8 “AA” 1.5v batteries.
1) Remove the battery compartment
hatch on the rear of the transmitter.
2) Install 8 fresh “AA” 1.5v alkaline
batteries, paying careful attention to
proper “+” and “-” polarity.
3) Slide the battery compartment cover
back into place until it locks.
4) Turn the transmitter on by sliding the
main power switch located on the front of the transmitter to the “On” position. Both
lights on your transmitter should be illuminated. If they are not, make sure you are
using all fresh alkaline batteries and recheck that the batteries have been inserted
using the proper polarity. If you still have problems, contact Megatech Support at
888-634-2911.
CAUTION
READ THIS SECTION BEFORE CHARGING YOUR BATTERY PACK FOR THE FIRST TIME!
• When using the DC charger, place the battery and charger on the ground outside the car on a re resistant material.
Never place a charging battery or charger inside your car.
• Never leave the battery and charger unattended while charging.
• Always let the ight pack cool completely before recharging.
• DO NOT OVERCHARGE THE BATTERY. Use extra caution when touching the battery because it may become very hot.
• NEVER attempt to use any charger not designed for use with this battery. It could result in battery damage.
• Never have the vehicle engine running during the DC charging process. This may cause overcharging and possible
damage to the battery. Note: Check your vehicle’s owner’s manual for full details on how your power outlet operates.
• Always disconnect the battery from the charger when charging is complete.
CHARGING YOUR FLIGHT PACK
Your new Prowler features two ways to charge your ight pack: via a wall outlet (AC) or
using your automobile’s cigarette lighter (DC).
• When performing an AC charge, begin by attaching the ight pack battery to the AC
charger’s connector and then plug the charger into a wall socket. Charging may take
up to three hours. Check the battery pack every 20 minutes. If it begins to feel warm,
charging is complete.

• When performing a DC charge, begin by turning o your car. Next, attach the ight
pack battery to the DC charger’s connector and then plug the charger into the
vehicle’s cigarette lighter or 12v Power Outlet. The charging light should glow red.
When charging is complete, the light will turn green. Charging may take about 2030 minutes. Note: Check your vehicle’s owners manual for full details on how your
power outlet operates.
Always monitor the charging process. Your ight pack will become warm, but do not
let it become extremely hot!
CYCLING THE FLIGHT PACK
NOTE: For peak performance and optimum flight duration, it is important to cycle the rechargeable
flight pack 3 times before flying. Cycling is only required before the initial flight.
1) Charge the battery pack as shown above.
2) Make sure the airplane and transmitter are switched to “OFF” and the left hand stick
of the transmitter is all the way DOWN then move the throttle trim tab below the
center position.
3) Turn the transmitter to the “ON” position.
4) Plug the ight pack into the plane.
5) Securely hold the airplane’s fuselage with the nose facing away from you. Be sure it
as far away from your person and any loose clothing or jewelry.
6) Push the left hand stick of the transmitter (the throttle stick) completely forward
until the battery runs out.
7) Allow the battery to cool COMPLETELY.
8) Repeat this process 2 more times.

FINAL ASSEMBLY
Attaching the Main Wing
• Carefully place the main wing onto the fuselage with the wing tips angled upwards.
The main support that is glued to the top of the wing should be facing furthest
forward.
• Check to make sure the arrows on the top center of the wing line up with the center
seam of the fuselage then push forward into place so that the leading edge of the
wing sits into the groove in the fuselage.
NOTE: When the wing is facing the proper direction and is seated correctly on the plane, the bottom of
the main wing should fit snug against the top of the fuselage.
• Connect the wing bands to the posts on the fuselage and wrap them across the wing
as follows. First attach a wing band from A to C and then attach another from B to D.
Next attach a wing band from A to D and then another from B to C.

Attaching the Horizontal Stabilizer
• Place the horizontal stabilizer on top of the vertical n, so the holes in the center
are aligned with the holes on top of the vertical n and the control horn is facing
downward. The horizontal stabilizer support should be facing up.
• Then, using a small Phillip’s head screw driver, insert the screws through the
stabilizer support, stabilizer and into the vertical n.
• Tighten the screws until they are snug, but not too tight. Over tightening can
damage your horizontal stabilizer.
Installing the Rudder & Elevator Pushrod
• To connect the elevator pushrod, begin by inserting the Z-bend into the outermost
hole on the servo arm that sticks out of the upper right side of the vertical n. Then,
connect the clevis (the locking portion) to the middle hole of the control horn on
the elevator as pictured.
• To connect the rudder pushrod, begin by inserting the Z-bend into the outermost
hole on the servo arm that sticks out of the lower left side of the vertical n. Then,
connect the clevis (the locking portion) to the middle hole of the control horn on
the rudder as shown.
10
Adjusting the Clevis
If you nd you need to adjust the clevis as indicated in the Flight Basics section on
page 12, use the following procedure:
• Detach the clevis from the control horn.
• To lengthen the pushrod, turn the clevis counter-clockwise.
• To shorten the pushrod, turn the clevis clockwise.
• Once complete, reattach the clevis to the control horn.
INSTALLING THE FLIGHT PACK BATTERY
• Open the battery hatch on front of the Prowler
fuselage by gently, but rmly, pulling up on the
front of the hatch.
• Carefully slide the ight pack into place between
the foam battery guards. Make sure the
connector is facing forward.
• Next, attach the battery connectors. Make sure
they are locked together rmly.
• Carefully lower the hatch, making sure the wires
& connectors are hidden beneath it.
• To disconnect the battery, press down on the
white tab located on the battery connector and
gently pull the connectors apart.
11
FLIGHT TRIM ADjUSTMENT
Make sure your trim levers are in the middle position excluding the throttle trim. The
throttle trim is required to always be below center or the airplane propellor will not
stop spinning when the throttle stick is pulled all the way back.
Throttle Trim Adjustment
If your propeller starts to spin without adding any
throttle or if it does not spin when you do add
throttle, your throttle trim needs to be adjusted.
If the propeller starts to spin without any throttle,
slide the throttle trim tab back until it stops. If
the propeller does not spin, even when you add
throttle, slide the throttle trim tab forward until
it starts spinning when the throttle is pushed
forward.
Rudder Trim Adjustment
If while ying, your Prowler begins to turn when
no rudder control input is being added, you will
need to adjust the rudder trim. If it turns to the
left, slide the rudder trim tab to the right until it
stops. If it turns to the right, slide the rudder trim
tab to the left until it stops.
Elevator Trim Adjustment
If your prowler begins to climb or descend when
no elevator control input is being added, you will
need to adjust the elevator trim tab. If the plane
descends, slide the elevator trim tab back until
the plane ies level. If the plane climbs slide the
elevator trim tab forward until it ies level.
NOTE: The airplane has a built in throttle failsafe. The propellor will not turn on during initial power up
unless the trim tab is below center and the throttle stick is all the way back.

FLIGHT SCHOOL
1) Choose a Flying Site & Weather Conditions
• Choose a large soft grassy open area to y in such as a
football or soccer eld. Do not y in a street or parking
lot.
• Never y near cars, people, pets, power lines, trees,
houses, buildings or water.
• Always keep the plane in front of you and never y over people’s heads.
• Be sure to keep your hands, eyes and face away from the propeller.
• Choose a day with little or no wind. Do not y in wind greater than 10 mph. Humidity
and temperature must be comfortable (around 50°F-85°F degrees) so that the air is
fairly dense.
• Attach the Wind Direction Ribbon to the end of your transmitter antenna to
determine the direction of the wind.
2) Pre-Flight Checklist (Perform in order)
Fully extend transmitter antenna.
REMEMBER: Your transmitter is always the first thing on and the last thing off.
Turn transmitter power switch to the ‘ON’ position. Check that both lights are lit.
Install a fully charged battery pack into the fuselage.
Holding the plane away from you, move the rudder control stick to ensure that
the rudder moves left and right accordingly.
Next, move the elevator control stick to ensure that the elevator moves up and
down accordingly.
Determine the direction of the wind using the Wind Direction Ribbon.
Make sure that the beginnner/expert switch is set correctly
depending on your skill and comfort level. See page 5
IMPORTANT: Check the power light on the transmitter often during a flight. If either of the lights dim
or go out, land the plane as soon as possible to avoid losing control. Then change the batteries in the
transmitter.
NOTE: 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!

3) Launching Your Prowler
• Determine the direction of the wind using the Wind Direction Ribbon. Always launch
your airplane INTO the wind. If you have difficulty determining the wind direction
using the ribbon, you can begin with the wind blowing in your face.
• Hold the plane’s fuselage directly under the main wing.
• Start with the plane above your shoulders.
• Push the Throttle control stick (left stick) all the way forward.
• Using the horizon as a 0-degree point of reference, take a running start and toss the
plane at a 5 degree upward angle into the wind. Use about the same force it takes to
throw a dart at a dart board.
• Once you have let go of the plane, continue to hold the throttle control stick all the
way forward.
• Pull back slightly on the elevator control stick (right stick) and allow the plane to
climb to a safe altitude (50-75 feet) before making your rst turn.
• Release the elevator control stick once you have gained the appropriate altitude.
Also pull back slightly on the throttle control stick to about 2/3 throttle.
• If the aircraft turns, climbs or dives with no control input, correct the ight path by
gently moving the right control stick in the appropriate direction.
• If further adjustments are needed, refer to the trim adjustment section on page 11.
TIP: Once you gain the altitude you want, pull back the throttle control stick and let the Prowler glide.
This will allow you to fly longer by extending battery life. When the plane gets too low to the ground,
add thrust by pushing the throttle control stick forward and add elevator by pulling back slightly on the
elevator control stick.

4) Turning your airplane
• Once your airplane has reached a safe altitude above the ground you are ready to
begin turning. You want to keep the model within 100 feet of you at all times.
TIP: Beginners Start with large oval circle patterns while learning.
Left Turn:
• Start the turn by feeding in a small amount of left rudder (push the right stick left),
assuming the plane is ying away from you.
• As the airplane turns left and the nose drops, gently feed in a little bit of up elevator
(pull the right stick back) just enough to keep the nose level.
• Bring the rudder control stick back to neutral (push the right stick to center) as the
aircraft completes the turn.
• When the plane is ying in the desired direction, feed in just a bit of right rudder
control input (tap the right stick right) to level the wings.
• If the plane is climbing excessively, tap the elevator control stick forward (tap the
right stick forward) for a little down elevator.
Right Turn:
• Start the turn by feeding in a small amount of right rudder (push the right stick right),
assuming the plane is ying away from you.
• As the airplane turns right and the nose drops, gently feed in a little bit of up elevator
(pull the right stick back) just enough to keep the nose level.
• Bring the rudder control stick back to neutral (push the right stick center) as the
aircraft completes the turn.
• When the plane is ying in the desired direction, feed in just a bit of left rudder
control input (tap the right stick left) to level the wings.
• If the plane is climbing excessively, tap the elevator control stick forward (tap the
right stick forward) for a little down elevator.
Flying toward you can be very tricky because the airplane will appear to be turning in
the wrong direction. This can be confusing at rst. Here’s a simple tip: When the model
is ying toward you, simply push the rudder stick in the direction of the wing tip that is
dipping low, and the model will right itself. Fairly soon this will become second nature
and you’ll be o and ying!
If the airplane gains too much altitude, try pulling back on the throttle control stick
(pull left stick back) and glide and turn until you reach a more comfortable altitude.
Do not panic if you see the plane begin to spin or make erratic movements. Simply
release the right control stick and the prowler should level o and return to a steady
glide as long as you have enough altitude.
16
5) Landing your Prowler
When you notice the nose of the airplane drop slightly or it is unable to climb, it is time
to land. You will still have enough power over the controls to set the airplane up for
a landing.
• Setup for a landing by making a gentle, shallow turn to face the airplane into the wind.
• When the airplane is level and facing into the wind, release the right control stick and
pull back on the throttle control stick. The plane will descend to the ground. Always
be sure the throttle control stick is all the way back when landing to avoid damaging
the propeller.
• If slight corrections are needed as the airplane makes its way to the ground, move
the right control stick in the appropriate direction, but only for a moment, so as to
keep the airplane descending on a straight heading. Also input a little up elevator if
needed, but only for a moment, so as to keep the airplane nose level.
• Over-steering will put the airplane into another turn or too much up elevator could
cause the plane to stall. If any of these issues occur the plane may crash if you are
too close to the ground. Keep the Prowler ying straight and level until it lands
safely.
• If it looks like you may overshoot your landing area, just let the plane settle down.

TRAINER CORD OPERATION
The trainer function is very eective for training student pilots. The included trainer cord is
required, to use this function.
The PF4000 trainer function lets you practice ying as a student by connecting the PF4000 to
the student’s transmitter. The PF4000 will act as the instructor’s transmitter. When two radios are
connected with the trainer cord, they are both capable of operating the model, but it is better
for the instructor to hold the radio that has been setup for the plane to be own (as it is already
programmed to y the model). When the instructor holds the trainer switch on his radio, the
student will have control. When the instructor wishes to regain control he simply releases the
switch. Then he will have immediate, full control of the airplane.
WARNING:
• Never turn on the student transmitter power switch.
(Turning on the power switch will cause interference and a crash)
• Set the student and instructor transmitters to the same settings.
(For example, if the direction of operation is reversed, control will be lost and the
plane will crash)
• The opposite side can only use a FM (PPM) type transmitter.
(If the modulation method is different, control is impossible)
Important note: If you are using a Megatech PF4000 radio for the student and the instructor transmitter you will
be required to power up the student transmitter and the instructor transmitter also. You must remove the student
transmitter’s crystal so that the student radio cannot transmit on any channel and will only work as a joystick with
the instructor radio. For all other brand of radios the student transmitter will always be switched “OFF” and the
instructor transmitter will be switch “ON”.
To use the trainer function, follow the basic steps below:
1. It is best for the instructor to use the transmitter that is already setup for the model to be
own.
2. The PF4000 radio system uses PPM (Standard FM) modulation only. You must set your student
radio to PPM also. If the student radio is PPM only, then no change is needed. Always make
sure that your radio matches the mode of the other radio.
3. Collapse the student’s antenna and fully extend the instructor’s antenna.
4. With both transmitters OFF, connect the trainer cord to both radios. On the PF4000 the
trainer jack is in the center of the rear of the transmitter case. Do not force the plug into the
transmitter and note that the plug is “keyed” so it can only go in one way.
Warning: Always make sure that the Transmitter is first thing on and the last thing off.
5. Turn on the instructor’s transmitter. DO NOT turn on the student’s transmitter since it will
automatically “power up”, but will not transmit a signal. Set the servo reversing and trims of
the student’s radio to match that of the instructor’s.
REMEMBER: If you are using a Megatech PF4000 for the student transmitter and the instructor’s transmitter, you
18
will be required to remove the crystal in the students PF4000 radio. You will then switch “ON” the student’s PF4000
transmitter and the instructor’s PF4000 transmitter.
6. Turn on the airplane as per the instructions. Depress the trainer switch on the instructor’s
radio by pulling forward and not releasing. Use the student’s radio to operate the controls
(elevator, rudder, and throttle) and observe how they respond. Make any adjustments
necessary to the student’s transmitter to get the controls to respond correctly.
7. Check to see that the trims are in “sync” by toggling the trainer switch back and forth a few
times. The controls on the model should remain stationary. If the controls do not remain
stationary, this indicates that the trim settings on the student’s radio do not match those on
the instructor’s radio. Adjust the student’s trims as necessary.
NOTE: The included trainer cable can be connected to most Futaba, Hitec and Megatech transmitters. If you
are using a newer style Futaba Radio with a square micro plug you can purchase the optional trainer cable by
contacting our sales department at 888-634-2911.
REPAIRING YOUR PROWLER
• If the main wing or tail set on your Prowler become damaged, simply apply clear
packing tape to the aected area.
• If major damage occurs, repair the damaged section using epoxy or foam safe glue or
replace the damaged part.
Replacing the Propeller
• When it is time to replace the propeller remove the center screw at the tip of the
spinner using a Philips screwdriver.
• Once the nose cone is removed loosen both screws that hold the propeller to the
motor shaft.
• Firmly, but carefully, pull the current propeller assembly o the motor shaft.
• Then, slide the new propeller assembly onto the motor shaft. Make sure that there
is at least 1/8 inch gap between the front of the motor mount screws and the back of
the propeller assembly. The propeller assembly should never touch the motor mount
screws.
• Tighten both screws that hold the propeller to the motor shaft. Do not over tighten.
• Attach the spinner to the propeller assembly.
• Tighten the center screw at the tip of the spinner. Do not over tighten.
