Assembly
The Tower DHC-2 Beaver may be assembled with either the
conventional landing gear or the included oats.
If installing the conventional landing gear, complete the following
two steps, then skip ahead to the Horizontal Tail Installation section.
If installing the oats, skip ahead to the Floats Installation section.
Landing Gear Installation
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 and tighten the screws.

5
Floats Installation
1. Connect the oats to each other with the horizontal struts and
four M2.5x20 machine-thread screws.
2. Use eight M2.5x8 screws to fasten the braces to the oats,
matching the labels printed or molded into the end of each
brace to the mount location on each oat.

6
3. Fasten the oat braces to the fuselage with one M3x16mm
screw and two M2.5x8mm screws in each side of the fuselage.
No screw is installed in the third strut at this time.
4. Connect a small rubber band to the inner side of each 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. Adjust the tension in the lines to
center the water rudders.

7
Horizontal Stabilizer Installation
1. Fasten the ns to each end of the horizontal stabilizer (stab) with
M2x6 screws.
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.

8
Vertical Stabilizer Installation
1. Key the rudder torque rod down into the receptacle while tting
the vertical stabilizer (n) into the fuselage. Tightly press the
assembly down into position.
2. Secure the horizontal and vertical stabilizers with the
M3x22 screw.

9
Wing Installation
1. Fasten the wing clips to both sides of the fuselage with four
M3x10 screws.
2. Guide the wires from the right wing into the fuselage, then slide
the wing joiner tube and the ap pushrod wire through the
corresponding holes. Also guide the ap pushrod wire into the
screw-lock connector on the ap servo.
3. Guide the joiner tube through the hole in the left side of the
fuselage, then tightly click the wing onto the wing clips.

10
5. Mount the top of each wing strut to the wing with a M2.5x8
machine-thread screw.
6. Mount the bottom of each strut to the fuselage over the third
oat strut (or over the main landing gear) with a M3x16 screw.
4. Mount the left wing the same way.

11
Receiver Installation
Install your receiver on the right side of the compartment in the
front of the fuselage, opposite of the electronic speed control,
connecting the servos according to the labels attached to the
wires. Follow the receiver manual recommendations for setup.
Battery Installation
The ight battery is installed in the angled middle section of the
front fuselage compartment and is held in place by the included
adhesive back hook and loop material.
1. Cut two 1-inch (25mm) strips from the rough, “hook” side of the
included adhesive back hook and loop material.
2. Apply the strips inside the fuselage where shown and press
them down tightly to adhere.
3. Cut a 3-inch (76mm) strip from the soft, “loop” side and attach it
to the battery
ESC Operation
1. Move the throttle stick to the lowest position.
2. Connect battery pack to the ESC.
The motor emits one low, long tone, the respective number
of medium-length mid-tones indicating the battery cell count,
followed by three rising tones to indicate the ESC is armed.

12
Connect the Rudder and Elevator
1. Power on the transmitter, fully lower the throttle stick, and center
the trims.
2. Connect the battery to the ESC.
TIP: 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.
3. Remove the screw from the connector on the elevator servo arm.
4. Lightly wet the threads of the screw with threadlocker.
5. Reinstall the screw, but do not tighten yet. With the transmitter
and receiver on, center the elevator and tighten the screw to
secure the pushrod.

13
6. Repeat the same procedure for the rudder, making sure it is
centered. Lock the pushrod in place on the servo arm with the
screw and threadlocker.
7. Disconnect the battery and power off the transmitter.
Connect the Lights, Flaps, and Ailerons
1. Connect the wing lighting wires and the aileron servo wires to
the lighting aileron and ap wiring harnesses coming from the
receiver.
2. Turn on the transmitter and install and connect the battery. Then
install and secure the hatch.

14
3. Move the dial or switch on your transmitter that controls the
aps to the “up” position, rotating the ap servo arm clockwise.
Remove the screw in the ap servo arm, wet the threads with
threadlock, and then reinstall and tighten the screw so the aps
will be in their fully retracted (“up”) position.
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.
TIP: 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 aileron servo covers to access
the pushrods. Adjust the pushrods in the connectors to get the
ailerons centered. When nished, replace the cover, press into
position, and hold in place with tape or a dab of glue.

15
Control Throws
Because the servos and pushrods are factory installed the control
throws should be correct. Because of the effect the control throws
have on a model, it’s always a good idea to conrm they are correct.
1. Conrm the controls respond 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 the aircraft is congured with the conventional landing gear,
prop up the back of the fuselage so the wings and stab are level.
3. Measure and set the control throws according to the
measurements below. Measure the throws at the widest part
(front-to-back) of each surface.
Recommended Control Throws
High Rate Low Rate
Up Down Up Down
Elevator 11mm 11mm 8mm 8mm
Ailerons 13mm 13mm 10mm 10mm
Rudder 32mm 32mm 22mm 22mm
Flap 11mm
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.

Propeller and Spinner Installation
Failure to follow these safety precautions may result in severe injury to yourself and others.
• 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.
• Never connect the battery to the ESC while indoors with the
propeller installed.
• Always remove the propeller when testing or making repairs to
the model.
• Always stay behind the arc of the propeller when handling the
model.
• Always assume the motor may start unexpectedly when the
ight battery is connected.
• Always remain outside the arc of the propeller when installing
and/or removing the ight battery.
• 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.
1. Secure the backplate, propeller, washer and nut. Make sure the
assembly is secure to the aircraft.
2. Tighten the two Phillips head screws to the spinner.

17
Center Of Gravity (CG)
Same as the control throws, the center of gravity has a great effect
on how every model ies.
• If the model is tail heavy it may be unstable and respond too
quickly to the controls.
• If the model is nose heavy it may be too stable and not respond
fast enough.
Either case may possibly cause a crash.
IMPORTANT: 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 2-1/2in (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
ngertips to balance.
2. Install the battery, battery hatch and cabin hatch. At this point
the Beaver must be in ready-to-y condition with everything
attached and installed including the oats or wheels and battery
and propeller.
3. Lift the model by your ngers between the lines indicating the
balance range. As long as the Beaver sits level with your ngers
on the forward or aft lines or anywhere between the lines it is
properly balanced and ready to y. If you have to move your
ngertips outside the lines the Beaver is out of balance and
should not be own. If necessary, add squares of stick-on
lead to the nose or tail to get the Beaver to balance within the
specied range.

18
Flying Tips
Before Every Flight
To help avoid ight accidents, ground inspections should be performed prior to every ight.
• Ensure all screws are secure, the servo arms and horns are
properly connected and the wing is properly secured.
• Install the recommended battery (not included), adjusting
the placement to ensure the center of gravity is correct, as
recommended in the manual.
• Ensure both the ight battery and the transmitter battery are
undamaged and fully charged.
• Ensure the transmitter throttle stick is at the lowest position prior
to powering on the aircraft.
• After the aircraft is powered on, perform a control surface check
to ensure both proper travel and the surfaces return to neutral
when the transmitter sticks are returned to neutral.
• With all body parts and loose items away from the propeller and
the aircraft securely held, gently push the throttle up to check for
correct rotation of the propeller.
• For inexperienced pilots, always seek assistance from an
experienced pilot.
When powering the aircraft on, make sure the throttle stick is in the
minimum (0%) position. Always power on the transmitter before
plugging the battery into the plane.
The aircraft ies mostly the same as any similar, high-wing
airplane, but you may 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 rst full roll.
Flying With Flaps
The only peculiarity arises when the aps are extended—if you
extend the aps too soon before the Beaver has lost enough ying
speed the nose will pitch up. Avoid this by making sure you have
given the Beaver enough time to slow after cutting the throttle. You
can also roll in the aps gradually. If you have a computer radio
you could also mix in some down elevator with aps. 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 aps extended the nose will
pitch up. Be prepared to counter with down elevator.
Flying From Water
Taken verbatim from our ight log book… “Flying the Beaver from
water with oats can be described with many adjectives including
astonishing, easy, fun, smooth, remarkable, etc.”
Unless weather conditions are poor, you should have no trouble
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 oats handle the water well. If the
winds are really high the Beaver can still be own from water, but
avoid turning it directly across the wind. The wind can get under
the wing and ip the aircraft over. In the air, the only effect of the
oats is that the Beaver ies slightly slower.
Power Consumption
Flying “normally” (using half-throttle for general cruising and full-
throttle only when required) the Beaver consumes about 200mAh/
minute for recommended ight times of about 7 minutes with an
1800mAh battery and about 8.5 minutes with a 2100mAh battery.
Flying more aggressively using higher throttle settings, the current
draw increases closer to 260mAh/minute for recommended ight
times of 5.5 minutes with an 1800mAh battery and 6.5 minutes
with a 2100mAh battery.
To nd out for yourself how long you can y, set your timer to a
conservative 5 minutes. Fly until the timer sounds, then land. Use
a charger with a digital display to 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 nd out how much you have available. Compare the capacity
used to 80% of your battery’s capacity and adjust your ight time
accordingly.
For example: If you’re using the recommended 1800mAh battery,
your target capacity to use for a ight is 1440mAh (1800mAh x
.8 = 1440mAh). If you y for 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 ight time
accordingly until you reach your 1440mAh target. (You could also
divide 1000mAh by ve minutes to gure a current consumption
rate of 200mAh/minute. Divide 1440mAh by 200mAh/minute to
conclude that you can y for 7.2 minutes [7 min. 12 sec.]—but
round down to 7 minutes.)
When powering down, always unplug the battery from the plane
before turning the transmitter OFF.
It’s also a great idea to use a LiPo battery checker (HCAP0275)
to check the battery before each ight (to make sure you haven’t
inadvertently grabbed a discharged battery) and to check the
battery after ight to make sure you haven’t over discharged your
battery by ying too long. A safe, conservative, minimum voltage is
3.65V – 3.7V per cell right after a ight.
One nal note about ying your model. Have a goal or ight plan
in mind for every 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 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 ight plan greatly reduces the
chances of crashing your model just because of poor planning and
impulsive moves. Remember to think.

19
Repairs
Electronic Speed Control Calibration
Parts damaged beyond repair can be purchased separately. Often
parts can be repaired and you can get your Beaver back into the
air with a little glue and ingenuity.
The Beaver is made from injection-molded EPO (expanded
polyole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 exible adhesives such as white glue or canopy
glue. These will require clamps or tape to hold the parts together
while the glue dries.
Troubleshooting
Problem Possible Cause Solution
Aircraft will not respond to the
throttle but responds to other
controls
ESC is not armed Lower throttle stick and throttle trim to lowest
settings
Throttle channel is reversed Reverse throttle channel on the transmitter
Extra propeller noise or vibration
Damaged spinner, propeller, motor or mount Replace damaged parts
Loose propeller and spinner parts Tighten parts for propeller adapter, propeller and
spinner
Propellor installed backwards Remove and install the propeller correctly
Reduced ight time
or aircraft is underpowered
Flight battery charge is low Completely recharge ight battery
Propeller installed backwards Remove and install the propeller correctly
Flight battery damaged Replace the ight battery and follow ight battery
instructions
Control surface does not move,
or is slow to respond to control
inputs
Control surface, control horn, linkage or servo
damage
Replace or repair damaged parts and adjust
controls
Wire damaged or connections loose Do a check of connections for loose wiring
Controls reversed Channels are reversed in the transmitter Do the control direction test and adjust controls
for aircraft and transmitter
Motor loses power or pulses
then loses power
Damage to motor or battery
Do a check of batteries, transmitter, receiver,
ESC, motor and wiring for damage and replace as
needed
ESC uses default soft Low Voltage Cutoff (LVC) Land aircraft immediately and recharge the ight
battery
LED on receiver ashes slowly Power loss to the receiver
Check connection from the ESC to the receiver
Check servos for damage
Check linkages for binding
CAUTION: Remove the spinner and propeller before
performing the electronic speed control calibration
procedure. Failure to remove the propeller may cause serious
injury in the event of accidental motor startup.
IMPORTANT: Because different transmitters have different
throttle ranges, calibrate throttle range before ying.
To set the throttle range
1. Move the throttle stick to the highest position.
2. Connect battery to the ESC. The motor will emit one low, long
tone to indicate startup, then the respective number of medium-
length mid-tones to indicate the battery cell count. The motor
sounds 2 long tones (B—B—), which means the highest position
of the throttle range is recognized by the ESC.
3. Move the throttle stick to the lowest position within 2 seconds of
the tones. The ESC recognizes the low throttle position and exits
the throttle range calibrating process.
