INTRODUCTION
Thank you for purchasing the Flyzone Zero. Not only is the
Zero popular because of its history and attractive outlines,
the Zero also happens to be one of those ideal scale subjects.
Its large wing and tail area, long tail moment and landing gear
placement make it a great flyer. And even though this Zero
is relatively small at about 15% scale, all the good flying
attributes still translate down to this Flyzone model, making
it an easy, enjoyable flyer!

ADDITIONAL ITEMS REQUIRED
RTF Edition
Other than ordinary hobby tools, nothing else is required to
complete the RTF edition of the Zero, but some pilots may
choose to upgrade the included Smart charger to a more
advanced charger for reduced charge times, and switch from
the included 3S battery to a 4S battery for increased flight
performance. Refer to the charger recommendation and list of
batteries under the list of items required for the Rx-R edition.
Rx-R Edition
Radio System
To operate all eight functions of the Flyzone Zero (ailerons,
elevator, throttle, rudder, retracts, flaps, releasable bomb,
lights) a minimum 7 channels is required. The lighting
harness may be connected to an additional, 8th channel,
or connected in-line to any other channel with a Y-harness
(FUTM4130). The Futaba 7C 7-channel 2.4 GHz FASST
airplane radio (FUTK7004) is suitable and capable of
operating all the functions.
LiPo Battery
The Flyzone Zero may be flown with either a 3S or 4S 2200mAh
30C battery. On 3S the Zero flies enjoyably and scale-like,
but a 4S battery will increase speed and vertical performance.
Following are the batteries recommended:
❍3S 11.1V 2200 mAh 30C LiPo (GPMP0861)
❍4S 14.8V 2200 mAh 30C LiPo (GPMP0862)
For additional batteries more adhesive-back hook-&-loop
Velcro is also required:
❍Great Planes Velcro Hook & Loop 1x 6" (GPMQ4480)
LiPo Charger
The Smart Charger included with the RTF is a safe way to
charge your LiPo battery, but it’s very basic and will take about
two hours to charge a normally depleted 2200 mAh battery. A
suitable upgrade over the Smart Charger (or a recommended
charger for the Rx-R version) is the DuraTrax Onyx 235 AC/
DC Advance Peak Charger (DTXP4235). The 235 features
110V AC or 12V DC input power, adjustable charge rate (to
charge the recommended 2200 mAh batteries in as little as
30 minutes) and an LCD digital display screen (so you can
see how much capacity it took to charge the battery – handy
for calculating optimum flight time).
Y-Harness
A minimum 7-channel transmitter is required to independently
operate all the functions of the Flyzone Zero. To operate
both the flaps and the releasable bomb with the included
TTX-600 6-channel transmitter, the flap and bomb release
servo must be connected with a Y-harness (FUTM4130 - not
included). To release the bomb, the flaps will have to be
partially extended with the flap dial. Another option would
be to disconnect either of the two servos from the receiver
making that function inoperable.

ASSEMBLY
Install the Tail Assembly
Halfway
Joiner
Collar
Torque rod
❏ 1. Install the horizontal stabilizer followed by the torque
rod and tail gear assembly– be certain the torque rod and
the tail gear wire meet in the middle of the joiner collar, then
use a 1.5mm hex driver with a drop of threadlocker on the
set screws to lock the assembly into position. If necessary,
adjust the tail gear wire in the joiner collar so the tail wheel
will be centered with the torque rod.
❏ 2. Install the vertical stabilizer while keying the torque rod
into the channel in the bottom of the rudder.
❏ 3. Fasten the horizontal and vertical stabilizer to the fuselage
with the M3 x 60 mm screw – a No. 1 Phillips screwdriver fits
best and will properly key into the head of the screw, making
it easier to detect when the screw is getting tight. Use care
not to overtighten the screw – turn until you feel resistance,
then go one additional turn. Tug on the vertical stabilizer to
make certain it is secure.

4
❏ 4. Fit the pushrods into the middle holes of the elevator
and rudder control horns, then install a 90 degree pushrod
keeper over the end of each pushrod. (Later, the pushrods
may require adjustment in the screw-lock connectors on the
servos.)
❏ 5. Before moving onto the wing, it would be a good idea
to remove the cowl and make a quick inspection of the motor
mount area. Make certain the ESC and motor are securely
fastened. Reinstall the cowl.
Set Up the Radio
CAUTION: Do not install the propeller until
instructed to do so.
Perform steps 1– 4 if assembling the RTF edition with the
included Tactic TTX600 transmitter. If assembling the Rx-R
with a different radio, connect the servos to the receiver and
a battery so you can power up the system and set the servo
reversing switches so the controls respond correctly.
❏ 1. Confirm that all four servo reversing switches in the front
of the transmitter are set to reverse. Install batteries in the
transmitter. Turn on the power and make certain the electronic
trims for the surfaces (aileron, elevator, rudder) are centered.
❏ 2. Connect a battery to the ESC so you can operate the
throttle. With the system on, advance the throttle just enough
to make the motor turn, then turn OFF the transmitter and
make sure the motor stops turning to confirm that the fail-
safe system is operating properly in the event of signal loss
(or if you ever accidentally turn off the transmitter before
disconnecting the battery).
Note: To start the motor, advance the throttle stick all the
way forward, listen to the beeps (counting the number of LiPo
cells – four beeps = 4S, three beeps = 3S), and then lower
the throttle stick. The motor will now turn.
❏ 3. If the motor doesn’t stop when you turn off the transmitter,
the receiver may need to be relinked to the transmitter to
reset the failsafe. Unhook the receiver from the hook & loop
patch in the fuselage. Turn on the transmitter and move the
throttle stick and throttle trim all the way down. Relink the
receiver and transmitter by using a small screw driver to
push and hold the “Link” button in the receiver until the LED
in the receiver blinks twice. Release the button and the LED
should remain illuminated indicating that the Tx and Rx are
once again linked.
❏ 4. Repeat step 2 to confirm that the failsafe is now
working properly.

5
Set Up the Flaps and Ailerons
Please disregard the missing bomb release servo in the
upcoming images. The decision to include the servo was
a last minute decision.
The ailerons and flaps are factory connected, but may
require a little fine tuning:
❏ 1. Place the wing and fuselage close together so you can
connect the wing servos to the receiver while it’s connected
to the ESC in the fuselage.
❏
2. Connect the aileron servo wire to channel 1 in the
receiver, the retract servo wire to channel 5 and the flap servo
to channel 6. (If assembling the RTF edition that comes with
the receiver installed, it may be easier to unhook the receiver
from the hook & loop and take it out of the fuselage.)
❏ 3. Turn the flap dial on the transmitter to retract the flaps.
If necessary, adjust the flap pushrods in the screw-lock
connectors on the flap servo so both flaps are fully retracted,
but the servo is not over-driving the flaps trying to pull them
up any farther than they can mechanically travel. Shorten or
lengthen the flap pushrods in the connectors as necessary
and retighten the screws.
❏ 4. Use the flap dial to extend the flaps to make sure they
extend evenly. If necessary, adjust the pushrods again to
make sure the flaps extend together. Note that the servo
may be able to push the flaps farther down than they can
mechanically travel, so be certain not to turn the dial too far.
❏
5. While working on the flaps, turn the wing over and make
certain the screws in the screw-lock connectors on the flap
horns are tight and secure.
❏ 6. Still with the system powered up, also make sure the
ailerons are centered and if necessary, adjust the pushrods
in the screw-locks on the aileron horns to center the ailerons.
❏ 7. With the wing servos still connected to the receiver and
the system powered up, extend and retract the landing gear
to make sure everything aligns and is operating correctly.
Make any adjustments necessary.

6
❏ 8. If you haven’t yet done so, replace the receiver back
into the fuselage. (If assembling the Rx-R edition, mount the
receiver in the fuselage with the included double-sided hook
& loop material.)
Mount the Releasable Bomb
❏ 1. Mount the bomb mount with two M3 x 20 screws and
the wire hook facing aft, while simultaneously inserting the
top of the wire release hook into the outer hole of the bomb
release servo arm (as shown in the image to the right).
Note: To release the bomb remotely, a 7-channel transmitter
and receiver will be required. Or, the flap servo may be
disconnected from the receiver, making a vacant channel
available for the bomb release – of course, then the flaps will
be disabled. Or, the flap and bomb servos may be connected
with a Y-harness (not included).
❏ 2. Connect the servo to an available channel in your receiver
and use this channel to release the bomb.
❏ 3. Disconnect the wing servo wires from the receiver, mount
the receiver in the fuselage, and then fasten the wing to the
fuselage with the M4 screw—it will be a little easier to install
and tighten the wing bolt without the bomb in the way, but if
the bomb is mechanically locked into place it’s easy enough
to access the wing bolt down between the fins of the bomb.

7
Final Assembly
❏ 1. Attach the rougher, hook side of the included hook &
loop material to the fuselage floor where shown for the battery.
❏ 2. Attach the softer, loop side of the included hook & loop
to the battery.
❏ 3. Connect the aileron, retract, flap and bomb release (if
used) servo wires to the receiver. Connect the lighting harness
to an available channel in the receiver – in the TR624 receiver
included, the vacant channel labeled “BAT” may be used.
❏ 4. Connect the lighting wire in the wing and the lighting
wire in the fuselage to the lighting harness.
❏ 5. All the controls should now be connected to the receiver.
Power up the radio (still without the propeller mounted!) so
you can operate the controls. Same as was done for the
flaps and ailerons on the wing, make certain the rudder and
elevator are centered, adjust the pushrods in the screw-lock
connectors if needed, and then make sure the screws in the
screw-lock connectors on the servo arms are tight and secure.
Check /Set the Control Throws
❏ 1. Use a small box or similar to raise the fuselage so the
horizontal stabilizer will be level or near level.
❏ 2. Measure and if necessary, use the programming in your
transmitter or adjust the throws mechanically to achieve the
throws specified in the following chart. If assembling the RTF
edition of the Flyzone Zero, the linkages are factory-connected
and the transmitter has no servo travel adjustments, so as
long as the throws are within 1/16" [1 – 2 mm] of the specified
throws this will be acceptable.
NOTE: The control throws are measured at the widest part of
each surface – at the root ends of the elevators and ailerons
and at the bottom of the rudder.

Mount the Propeller
We’ve found it unnecessary to balance the included 10 x 6
3-blade propeller, but detail-minded pilots who demand the
most performance may balance the propeller on a precision
balancer such as the Top Flite Power Point Propeller Balancer
(TOPQ5700). In any case, if you ever detect unusual noise
or vibration from the prop or motor, land the plane and find
the source of the problem.
❏ 1. Install the prop/spinner assembly onto the motor shaft.
Then, tighten with a 10 mm or 3/8" wrench (or a crescent
wrench).
❏ 2. Install the spinner cone and secure with the M3 spinner
screw.
Install the Antenna
Fit the removable antenna into place through the opening in
the back of the canopy – it may be a good idea to remove the
antenna during transport to avoid damage.
Check the C.G. (Center of Gravity)
The model must be in ready-to-fly condition with everything
installed including the propeller. But it doesn’t matter whether
the Zero is balanced with the gear up or down or with the
bomb attached or not as any minute shift in C.G. has been
accounted for in the specified range.
Forward panel lines
2-3/4" [ 70mm] back from the leading
edge at the fuselage +/ - 1/2" [13 mm]
Recommended starting C.G. location

❏ 1. Install the battery and canopy. Balance the model upside-
down and support the wing on both sides of the fuselage at the
starting, recommended C.G. location which is 2-3/4" [70mm]
back from the leading edge of the wing – conveniently, this
location is also at the forward panel line which you can feel
with your fingertips when supporting the model.
❏ 2. If necessary, reposition the battery to get the model
to balance. Once the correct battery location has been
determined you could mark the location on the inside of the
fuselage so you will know where to install it every time.
The full C.G. range is 2-1/4 in [57 mm] – 3-1/4 in [ 83 mm] back
from the leading edge of the wing at the fuselage. You may
shift the C.G. within the specified range to change the flying
characteristics to suit your taste – balanced farther back the
Zero will become more maneuverable and less stable, but also
float longer on landing. Balanced nearer the front of the C.G.
range the Zero will be more stable (less aerobatic), but also
better suited to flying at higher speeds or windier conditions.
Balancing the model outside the range could make the Zero
difficult to fly, possibly causing a crash. So always fly your
Zero within the specified range.
Set a Flight Timer
It’s better to limit your flying time with a timer set to a pre-
calculated time instead of waiting for the LVC (low voltage
cutoff) in your ESC to kick in or until you notice a decrease in
flight performance. By then, it may be too late to make more
than one landing attempt.
Typical, average battery consumption with the Flyzone Zero
is approximately 220 mAh/minute on 3S and approximately
320 mAh/minute on 4S. But your flying style, battery condition
and weather conditions may cause these figures to vary, so until
you know for sure, start by setting your timer conservatively
to 6 or 4 minutes respectively. If your transmitter has a timer
built in, link the timer to your throttle stick so only motor run
time is counted. Fly until the timer sounds and land. Note
the time on your transmitter and charge the battery. If your
charger has a digital readout (indicating how much capacity
it took to recharge which indicates how much capacity was
used during the flight), divide the capacity that went back
into your battery by the flight time to calculate your average
battery consumption for that flight. Divide 80% of your
battery capacity by that consumption rate to determine your
new, target flight time.
Example:
Suppose you are using a 2200 mAh battery and after you
landed, the motor run time on the timer was four minutes,
fifteen seconds (that’s 4.25 minutes in tenths). And say it
took 1290 mAh to recharge your battery.
Divide 1290 mAh by 4.25 minutes to calculate an average
battery consumption rate of about 300 mAh per minute.
Your limit capacity to use from a 2200 mAh battery is 1760 mAh
(2200 mAh x 0.8), so 1760 mAh divided by 300 mAh/minute =
5.8 minutes (approximately 5 minutes, 45 seconds).
Maybe on your second flight set your timer to 5 minutes and
repeat the procedure to continue to log data for calculating
average target flight times.
The more data you log and the more calculations you do,
the more accurate your calculated flight times will be – so
you never have an unplanned dead-stick landing or over
discharge your batteries.

10
Here’s a worksheet you can use for recording flight times and recharge capacity to calculate target flight times (as well as
average, in-flight current which is also useful data). The second row contains formulas for the calculations for that row. Row
#1 is already filled out with figures from the example:

start working. Otherwise, the Zero occasionally exhibits the
tendency to nose down slightly during initial rollout. But once
up to speed you can keep in the main wheels on the ground
for a beautiful, scale-like rollout as long as you please!
There’s nothing particular to note about the Zero once
airborne – on 3S it flies quite “scale-like,” and on 4S the Zero
is significantly faster with increased vertical performance.
Again alluding to the Zero’s scale-like flight tendencies, it
does land a little better if you fly it in with a little throttle–
especially if landing with flaps. Same as most warbirds, the
Zero is somewhat of a draggy airframe and bleeds off speed
a little faster than your typical sport plane. Just leave a few
clicks of throttle in, wait for it to slow and you’ll see it flairs or
two-points beautifully.
You’ll find that flaps aren’t necessary if landing in breezy
conditions. But if the weather is calm the flaps will slow the
Zero even more!
SAFETY PRECAUTIONS
Protect Your Model, Yourself & Others…
Follow These Important Safety Precautions
1. Your Zero 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
Zero, if not assembled and operated correctly, could possibly
cause injury to yourself or spectators and damage to property.
2. You must assemble the Zero according to the instructions.
Do not alter or modify the model, as doing so may result in an
unsafe or unflyable model. In a few cases the instructions may
Additionally, or if you don’t have a charger with a digital readout
to find out how much capacity you used during a flight, use a
LiPo cell checker to check individual cell voltage after each
flight. The resting, non-loaded, individual cell voltage after a
flight should be no less than 3.7 V/cell.
FLYING
The Zero doesn’t exhibit any negative flight tendencies, but
here are a couple of tips that will help you present your Zero
better out at the flying field.
Choose a suitable takeoff and landing surface of short grass
or a smooth surface.
On the 4S battery the Zero is aerobatic and speedy, but it
still likes to be treated like a scale model. During the initial
few feet of the takeoff roll use up elevator to hold the tail
on the ground until it gains a little speed and the surfaces

11
differ slightly from the photos. In those instances the written
instructions should be considered as correct.
3. You must use an R/C radio system that is in good condition.
All components must be correctly installed so that the model
operates correctly on the ground and in the air. You must
check the operation of the model and all components before
every fl i g h t .
4. If you are not an experienced pilot or have not flown this type
of model before, we recommend that you get the assistance
of an experienced pilot in your R/C 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.
5. While this kit has been flight tested to exceed normal
use, if the plane will be used for extremely high stress flying,
such as racing, or if a motor or battery larger than ones 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.
We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and flyability of your finished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model, and
no representations are expressed or implied as to the
performance or safety of your completed model.
Motor Safety Precautions
Failure to follow these safety precautions may result
in severe injury to yourself and others.
●Wear safety glasses whenever running motors.
●Keep your face and body as well as all spectators away
from the plane of rotation of the turning propeller.
●Keep loose clothing and objects such as pencils or
screwdrivers that may fall out of shirt or jacket pockets
away from the prop.
