INTRODUCTION

Thank you for purchasing the Flyzone 1/10th-scale de Havilland

DHC-2 Beaver RTF/Tx-R. For anybody who enjoys fl ying fl oat
planes or who aspires to do so for the fi rst time, the Flyzone
Beaver is the perfect choice because it maneuvers and fl ies
off the water so well—you virtually can’t mess up a takeoff or
landing unless you try! Of course, the Beaver is almost just
as much at home on dry land as it is in the water. And with
the fl aps extended you can set your Beaver down on water
or on land as light as a feather.

SAFETY PRECAUTIONS

PROTECT YOUR MODEL, YOURSELF AND OTHERS...
FOLLOW THESE IMPORTANT SAFETY PRECAUTIONS

1. Your de Havilland Beaver 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 Beaver, if not assembled and operated correctly, could
possibly cause injury to yourself or spectators and damage
to property.

For the latest technical updates or manual corrections to the
Beaver, visit the Flyzone site at www.fl yzoneplanes.com. Open
the “Airplanes” link, then select the Beaver ARF. If there is
new technical information or changes to this model a “tech
notice” box will appear in the upper left corner of the page.

Academy of Model Aeronautics

If you are not already a member of the AMA, please join! The
AMA is the governing body of model aviation and membership
provides liability insurance coverage, protects modelers’ rights
and interests and is required to fl y at most R/C sites.

IMPORTANT!!! Two of the most important things you can
do to preserve the radio controlled aircraft hobby are to avoid
fl ying near full-scale aircraft and avoid fl ying near or over
groups of people.

2. You must assemble the Beaver according to the instructions.
Do not alter or modify the model, as doing so may result in an
unsafe or unfl yable model. In a few cases the instructions may
differ slightly from the photos. In those instances the written
instructions should be considered as correct.

3. 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 ight.

4. If you are not an experienced pilot or have not fl own this type
of model before, we recommend that you get the assistance
of an experienced pilot in your R/C club for your fi rst fl ights.
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 fl ight tested to exceed normal
use, if the plane will be used for extremely high stress fl ying,
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.

2

We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished 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.

Remember: Take your time and follow the instructions to
end up with a well-built model.

REQUIRED FOR COMPLETION

Other than a #1 and #2 Phillips screwdriver and a few drops
of non-permanent threadlocker (GPMR6060), no adhesives
or anything extraordinary is required to assemble the Beaver.

The RTF is fully equipped with a complete radio control

system, LiPo battery and charger, so no other accessories
are required, but the following items are required to complete
the Tx-R edition:

Transmitter

The Tx-R includes the Tactic™ TR624 6-Channel 2.4GHz

receiver, so you’ll need either a Tactic TX600 6-channel 2.4GHz
transmitter, or any other 5-channel (or more) transmitter
compatible with the Tactic AnyLink™ 2.4GHz radio adapter*.
Using the AnyLink allows any compatible transmitter to work
with the Tactic receiver.

❍ TX600 6-channel transmitter (TACJ2600)

❍ AnyLink radio adapter* (TACJ2000)

*In addition to the AnyLink radio adapter, some AnyLink-

compatible transmitters may also require additional adapter
cables. Visit Tx-Ready.com to see the AnyLink compatibility
chart or contact Product Support at the contact information
on this page.

LiPo Battery

The RTF edition of the Beaver includes a Flyzone 3S (11.1V)
1800mAh 20C LiPo battery and the same is recommended for

the Tx-R, but a 2100mAh battery is also an option for slightly
longer fl ight times (more about fl ying time on page 15).

❍ Flyzone 3S (11.1V) 1800mAh 20C LiPo battery

(HCAA6430)

❍ Flyzone 3S (11.1V) 2100mAh 20C LiPo battery

(HCAA6387)

replaced with a Deans Ultra Plug® male connector which will
require soldering (but is a simple task for those so equipped).

Charger

The RTF comes equipped with a Great Planes 3S LiPo

balancing Smart Charger, but the Tx-R requires a charger to
be purchased separately. The Smart Charger is a safe way to
charge your LiPo battery, but it’s very basic and just enough
to get you started. The Smart Charger charges at a rate of .8

Amps, so it will take at least one-and-a-half hours or more to

charge your battery. For those who have the RTF and wish
to upgrade their charger, or those with the Tx-R who must
purchase a charger anyway, the Duratrax® Onyx™ 235 AC/
DC Advanced Peak Charger (DTXP4235) is recommended.

The Onyx is perfect for 3S batteries used with the Beaver

and may be powered either by an external DC power source
(such as a 12V battery), or a 110V AC outlet. The Onyx also
has an adjustable charge rate to charge your batteries in as
little as a half-hour or less (depending on the condition of your
batteries and the manufacturer’s specifi ed charge rate). The
Onyx can also charge larger batteries and batteries other than
LiPos, so it is a versatile charger you can grow into. Finally, the
235 features an LCD digital display screen, so you can see
how much capacity it took to recharge the battery (required
for monitoring the condition of your batteries and calculating
how long you can fl y).

NOTE: For use with the Onyx 235, LiPo batteries that come
with a SuperTigre connector (such as the Flyzone batteries
recommended) require a banana plugs-to-SuperTiger charge
lead (SUPM0070). And batteries that come with a Deans Ultra
Plug connector require a Charge Lead with banana plugs/
Deans Ultra Plug Male charge lead (GPMM3148).

KIT INSPECTION

Before assembly, take an inventory of this kit to make sure
it is complete, and inspect the parts to make sure they are
of acceptable quality. If any parts are missing or are not of
acceptable quality, or if you need assistance with assembly,

ASSEMBLY

NOTE: This instruction manual applies to both the RTF
and Tx-R editions of the de Havilland Beaver. If assembling
the RTF edition, simply skip steps that do not apply.

Mount the Landing Gear

Mount the Floats

1. Use a #2 Phillips screwdriver to fasten both main landing

❏

gears to the fuselage with three M3x16 screws in each side.

2. Mount the tail gear with two M2.5x8 screws, then fasten

❏

the pushrod wires as shown. Make sure the tail wheel is
perpendicular with the steering arm.

1. Connect the fl oats to each other with the horizontal struts

❏

and four M2.5x20 machine-thread screws.

5

2. Use eight M2.5x8 screws to fasten the braces to the

❏

fl oats, matching the labels printed or molded into the end of
each brace to each mount location on each fl oat.

4. Connect a small rubber band to each fl oat and water

❏

rudder as shown.

5. Fasten the wire hooks on the end of each rudder line

❏

to the connectors in the steering arm. As best as you can,
adjust the tension in the lines to center the water rudders—the
rudders don’t have to be perfectly centered, because over
time they may drift anyway, and the rudders are forgiving and
overall water handling is easy.

3. Fasten the fl oat braces to the fuselage with one M3x16mm

❏

screw and two M2.5x8mm screws in each side of the fuselage.

Mount the Horizontal

and Vertical Stabilizer

1. Fasten the vertical stabilizers to each end of the horizontal

❏

stabilizer (stab) with M2x6 screws.

6

2. Connect the elevator pushrod to the bottom hole in the

❏

elevator horn as shown.

3. Rotate the stab upward and key it into the fuselage.

❏

4. Key the rudder torque rod down into the receptacle while

❏

fi tting the vertical stabilizer (fi n) into the fuselage. Tightly press
the assembly down into position.

7

5. Secure the stab and fi n with the M3x22 screw.

❏

Install the Battery

2. Cut a 3" [76mm] strip from the softer, “loop” side and

❏

attach it to the battery so the larger “discharge” wires will be on
the right side as shown. (This will position the wires opposite
the receiver for a better fi t.)

Hook Up the Rudder and Elevator

1. Turn on the transmitter, lower the throttle stick all the

❏

way, center the trims and make sure the throttle channel in
your transmitter is in the “reverse” position.

1. Cut two 1" [25mm] strips from the rougher, “hook” side

❏

of the included adhesive-back hook-and-loop material. Apply
the strips inside the fuselage where shown and press them
down tightly so they adhere.

2. Connect the battery to the ESC. If all is working properly,

❏

the ESC will send three, short, electrical pulses to the motor
causing it to chime three times (“ 1- 2- 3”) followed by a longer,

8

single, lower tone beep (“BEEEP”) followed by a shorter, higher
tone beep (“beep”). If the chimes and beeps do not sound in
this manner refer to “MOTOR/ESC OPERATION” on page

15 to setup the transmitter and ESC correctly.

A magnetic screwdriver, or a small magnet stuck to a screw
driver to make it magnetic, will be helpful for the next couple
of steps.

5. Reinstall the screw, but do not tighten yet. With the

❏

transmitter and receiver on, center the elevator and tighten
the screw to lock the pushrod down.

3. Remove the screw from the connector on the elevator

❏

servo arm.

6. Repeat the same procedure for the rudder, making

❏

sure it is centered. Lock the pushrod down with the screw
and threadlocker.

7. Disconnect the battery and turn off the transmitter.

❏

Mount the Wings

4. Lightly wet the threads of the screw with threadlocker.

❏

1. Fasten the wing clips to both sides of the fuselage with

❏

four M3x10 screws.

9

3. Mount the left wing the same way.

❏

4. Mount the top of each wing strut to the wing with a

❏

M2.5x8 machine-thread screw.

2. Guide the wires from the right wing into the fuselage, then

❏

slide the wing joiner tube and the fl ap pushrod wire through
the corresponding holes. Also guide the fl ap pushrod wire into
the screw-lock connector on the fl ap servo. Guide the joiner
tube through the hole in the left side of the fuselage, then
tightly “CLICK!” the wing onto the wing clips.

5. Mount the bottom of each strut to the fuselage over the

❏

fl oat strut (or over the main landing gear) with a M3x16 screw.

10

Hook Up the Flaps and Ailerons

1. Connect the wing lighting wires and the aileron servo

❏

wires to the lighting and fl ap wiring harnesses coming from
the receiver.

2. Turn on the transmitter and install and connect the battery.

❏

Then install and secure the hatch.

3. Move the dial or switch on your transmitter that controls

❏

the fl aps to the “up” position, rotating the fl ap servo arm
clockwise. Remove the screw in the fl ap servo arm, wet the
threads with threadlocker, and then reinstall and tighten the
screw so the fl aps will be in their fully retracted (“up”) position.

Check the Control Throws

Because the servos and pushrods are factory-installed

the control throws should already be correct, but because
of the effect the control throws can have on a model, it’s
always a good idea to check them anyway.

4. With the system still on, make sure the ailerons are

❏

centered and aligned with the wing tips. If necessary, apply a
few clicks of aileron trim to get the ailerons centered. If more
than a few clicks of trim are required, or if you cannot get both
ailerons neutralized, a small screwdriver may be used to pop
off one or both fl ap servo covers to access the pushrods.
Adjust the pushrods in the connectors to get the ailerons
centered. When fi nished, replace the cover, press into position,
and hold in place with tape or a dab of glue.

1. Confi rm that the controls are responding in the correct

❏

direction according to control inputs from the transmitter. If
necessary, use the servo reversing program in your transmitter
to change the servo direction of any controls that are moving
the wrong way.

2. If your de Havilland Beaver is confi gured with wheels,

❏

use a small box or something similar to prop up the bottom
of the fuselage under the tail so the wings and stab are level
(or nearly level).

3. Measure and set the control throws according to the

❏

measurements below. The throws are measured at the widest
part (front-to-back) of each surface.

4. If any of the control throws require adjustment use the

❏

programming in your transmitter to increase or decrease the
throws accordingly. If the programming isn’t enough or if your
radio doesn’t have adjustable throws, the pushrod connectors
on the servo arms can be relocated in different holes inward
or outward to increase or decrease the throw—moving the
pushrods inward on the servo arms decreases the throw and
moving the pushrods outward on the servo arms increases
the throw.

Check the C.G.

Same as the control throws, the C.G. has a great effect on how
every model fl ies, so do not skip this procedure. If the model
is tail-heavy it may be too instable and respond too quickly to
the controls. If the model is nose-heavy it may be too stable
and not respond fast enough—in either case possibly causing
a crash. Do not overlook this important procedure.

1. Mark the forward and aft C.G. limits on both sides of

❏

the bottom of the wing 2" and 2-1/2" [51mm and 64mm] back
from the leading edge where shown—using narrow strips of
tape will allow you to feel the marks when lifting the model
with your fi ngertips to balance.

3. Install the battery, battery hatch and cabin hatch. At

❏

this point the Beaver must be in ready-to-fl y condition with
everything attached and installed including the fl oats or wheels
and battery and propeller.

4. Lift the model by your fi ngers between the lines indicating

❏

the balance range. As long as the Beaver sits level with your
fi ngers on the forward or aft lines or anywhere between the
lines it is properly balanced and ready to fl y. If you have to
move your fi ngertips outside the lines the Beaver is out of
balance and should not be fl own. If necessary, add squares
of stick-on lead to the nose or tail to get the Beaver to balance
within the specifi ed range.

2. Mount the propeller and spinner.

❏

MOTOR SAFETY PRECAUTIONS

Failure to follow these safety precautions may result in
severe injury to yourself and others.

● Seek the assistance of an experienced pilot if new to

electric motors.

● Wear safety glasses whenever in the proximity of a

spinning propeller.

● Do not operate the motor in an area of loose gravel or

sand; the propeller may throw such material in your face
or eyes.

● Keep spectators as well as your own face and body out

of the plane of rotation of the propeller.

14

● Keep all loose clothing, long hair or any other loose objects

such as pencils or screwdrivers that may fall out pockets
away from the propeller.

MOTOR / ESC OPERATION

Turning on the transmitter and running the motor is intuitive

for most pilots who already have experience with electric
motors, but for those who may have little or no experience
with electric motors here are basic operating instructions for
the ESC and motor:

When ready to fl y and running the motor, fi rst turn on the
transmitter and make sure the throttle stick is all the way down.
Always securely hold onto the model when connecting the
battery. The propeller should not turn, but expecting it to do so
anyway will prevent an accident or injury. Connect the battery
to the ESC. The ESC will send three short electrical pulses to
the motor, causing it to chime three times (“ 1- 2- 3”) followed
by a longer, single, lower tone beep (“BEEEP”), followed by
a shorter, higher tone beep (“beep”). The model is ready to
fl y and the propeller will turn when the throttle is advanced.

If the transmitter is not turned on before the battery and
ESC are connected (so the receiver is not receiving a signal)
the motor will still chime three times (“ 1- 2- 3”), but then it
will sound consecutive, higher tone beeps (“beep,” “beep,”

“beep,”….) until the transmitter is turned on at which time it

will emit a single, lower tone beep (“BEEEP”) followed by the
single higher tone beep (“beep”).

If, when the battery is connected to the ESC the throttle stick
is not all the way down the motor will beep rapidly (“beep beep
beep beep beep…”) until either the battery is disconnected or
the throttle stick is returned to the off position at which time it
will emit a single, lower tone beep (“BEEEP”) followed by the
single higher tone beep (“beep”).

FLYING

The Beaver fl ies mostly the same as any similar-type, high-wing

airplane, but you may fi nd that the roll rate is a little slower.
This suits the Beaver well as it is a scale-like, STOL (Short
TakeOff and Landing) craft. Just give yourself more time and

altitude before trying your fi rst full roll.

The only peculiarity arises when the fl aps are extended—if you

extend the fl aps too soon before the Beaver has lost enough

fl ying speed the nose will pitch up. The way to avoid this is

fi rst by making sure you have given the Beaver enough time

to slow after cutting the throttle. You can also roll in the fl aps

gradually. If you have a computer radio you could also mix in

some down elevator with fl aps. In any regard, once the Beaver

reaches “equilibrium” and has initiated a gliding descent the

nose will resume a normal, downward glide angle. Similarly,

when powering up the throttle with the fl aps extended the

nose will pitch up, so be ready to counter with down elevator.

Unless weather conditions are terrible, you should have no
trouble fl ying the Beaver from either rough or calm water.

The water rudders direct the Beaver well and they don’t have

to be perfectly centered to be effective (so don’t spend an
exorbitant amount of time on the work bench working on
them!). The Beaver turns more tightly at idle speeds, so if you
need to do a U-turn throttle back to bring the Beaver around.

At higher speeds during a takeoff run the water rudders have

the correct amount of effectiveness to steer the Beaver on its
intended path. Takeoffs can be long and graceful or short and
steep—either way the fl oats handle the water well. If the winds
are really high the Beaver can still be fl own from water, but
avoid turning it directly across the wind. Otherwise, the wind
can get under the wing and fl ip the Beaver over. In the air, the
only effect of the fl oats is that the Beaver fl ies slightly slower.

Flying “normally” (using half-throttle for general cruising and
full-throttle only when required) the Beaver consumes about
200mAh/minute for recommended fl ight times of about 7
minutes with an 1800 mAh battery and about 8.5 minutes with
a 2100 mAh battery. Flying more aggressively using higher
throttle settings, the current draw increases closer to 260mAh/
minute for recommended fl ight times of 5.5 minutes with an

1800 mAh battery and 6.5 minutes with a 2100mAh battery.

To fi nd out for yourself how long you can fl y, set your timer

to a conservative 5 minutes. Fly until the timer sounds, then
land. Use a charger with a digital display to fi nd out how
much capacity it took to recharge the battery (indicating how
much capacity was used). To avoid over discharging your
LiPos use only 80% of your battery’s capacity, so multiply
your battery’s capacity by .8 to fi nd out how much you have
available. Compare the capacity used to 80% of your battery’s
capacity and adjust your fl ight time accordingly.

For example: If using the recommended 1800mAh battery,
your target capacity to use for a fl ight is 1440 mAh (1800mAh x

.8 = 1440 mAh). If you fl y for fi ve minutes and it takes 1000mAh

to recharge your battery, you still have 440mAh to go before
you should land, so adjust your timer to increase your fl ight
time accordingly until you reach your 1440mAh target. (You
could also divide 1000 mAh by fi ve minutes to fi gure a current
consumption rate of 200mAh/minute. Divide 1440mAh by
200 mAh/minute to conclude that you can fl y for 7.2 minutes
[7 min. 12 sec.]—but round down to 7 minutes.)

Taken verbatim from our fl ight log book… “Flying the Beaver

from water with fl oats can be described with many adjectives

including astonishing, easy, fun, smooth, remarkable, etc.”

It’s also a great idea to use a LiPo battery checker (HCAP0275)

to check the battery before each fl ight (to make sure you

haven’t inadvertently grabbed a discharged battery) and to

check the battery after fl ight to make sure you haven’t over

discharged your battery by fl ying too long. A safe, conservative,

minimum voltage is 3.65V – 3.7V per cell right after a fl ight.

REPAIRS

The Beaver is made from injection-molded EPO (expanded

polyolefi n) foam which can be glued with just about anything.
Most people use regular CA. With CA no clamping is required,
but some prefer softer, more fl exible adhesives such as white
glue or canopy glue. These will require clamps or tape to hold
the parts together while the glue dries.

One fi nal note about fl ying your model. Have a goal or fl ight
plan in mind for every fl ight. This can be learning a new
maneuver(s), improving a maneuver(s) you already know,
or learning how the model behaves in certain conditions
(such as on high or low rates). This is not necessarily to
improve your skills (though it is never a bad idea!), but more
importantly so you do not surprise yourself by impulsively
attempting a maneuver and suddenly fi nding that you’ve run
out of time, altitude or airspeed. Every maneuver should be
deliberate, not impulsive. For example, if you’re going to do a
loop, check your altitude, mind the wind direction (anticipating
rudder corrections that will be required to maintain heading),
remember to throttle back at the top, and make certain you
are on the desired rates (high/low rates). A fl ight plan greatly
reduces the chances of crashing your model just because
of poor planning and impulsive moves. Remember to think.

Parts damaged beyond repair can be purchased separately.
The full replacement part list is printed in the front of the manual

on page 4. Often though, parts can be repaired and you can

get your Beaver back into the air with a little glue and ingenuity.

Have a ball! But always stay in control

and fl y in a safe manner.

GOOD LUCK AND GREAT FLYING!
