The full-scale DHC-2 Beaver was originally intended for flight in
areas of remote wilderness. Designed to be particularly durable
and powerful, the Beaver could easily be fitted with wheels, skis
or floats depending on where it was needed. The Beaver had
short takeoff and landing capabilities, making it perfect to reach
areas that could normally only be accessed via boat or foot.
Originally designed in 1948, the Beaver quickly made itself
useful flying to frozen areas of Canada and Alaska. Despite
the fact that production ceased in 1967, it is still used today for
island-hopping tourists and fishermen.
E-flite’s DHC-2 Beaver 25e is part of the Platinum Series,
meaning the level of scale detail is unmatched. Just a few of its
amazing details include corrugated flight surfaces, concealed
tail linkages and a scale dummy motor. Also included with the
E-flite Beaver are float mounts built into the fuselage and the
wire struts required to bolt the floats onto. For additional fun,
the pilot can quickly change the landing gear to the optional
float set (EFLA500) for water takeoffs and landings.
For anyone looking for an authentic-looking replica of a durable
utility plane with amazing scale detail that is easy to assemble,
the Beaver is the sport utility vehicle of aircraft.
Platinum Series Statement
Our Platinum Series delivers superior, enhanced features and
meticulous attention to detail. The symbol on this kit is your
assurance of excellence and one more way that E-flite brings you
the most advanced electric flight experience.

Using the Manual
This manual is divided into sections to help make assembly
easier to understand, and to provide breaks between each
major section. In addition, check boxes have been placed next
to each step to keep track of each step completed. Steps with
a single circle () are performed once, while steps with two
circles ( ) indicate that the step will require repeating, such
as for a right or left wing panel, two servos, etc.
Remember to take your time and follow the directions.

Notes Regarding Servos and ESC
Warranty Information
WARNING: Use of servos other than those we recommend may
overload the BEC of the recommended Electronic Speed Control
(ESC). We suggest the use of only the servos we recommend
when utilizing the recommended ESC’s BEC, or the use of a
separate BEC (like the UBEC) or receiver battery pack when
using other servos.
Note on Lithium Polymer Batteries
Lithium Polymer batteries are significantly more
volatile than alkaline or Ni-Cd/Ni-MH batteries used
in RC applications. All manufacturer’s instructions
and warnings must be followed closely. Mishandling
of Li-Po batteries can result in fire. Always follow the
manufacturer’s instructions when disposing of Lithium
Polymer batteries.
Warning
An RC aircraft is not a toy! If misused, it can cause serious
bodily harm and damage to property. Fly only in open areas,
preferably at AMA (Academy of Model Aeronautics) approved
flying sites, following all instructions included with your radio.
Keep loose items that can get entangled in the propeller away
from the prop, including loose clothing, or other objects such as
pencils and screwdrivers. Especially keep your hands away from
the propeller.

Important Information About Your Propeller
It is also very important to check to be sure the
propeller is balanced before installing onto the shaft. An
unbalanced propeller may strip the gears or cause poor
flight characteristics.
Note: If it is necessary to enlarge the hole in the
propeller, make sure to check the balance of the
propeller afterwards.
Note: Some DHC-2 beaver's utilized a spinner and
some did not. We have included a spinner for you if you
so wish to use one. On the model we have represented,
we did not use a spinner; we used only a prop nut.

the hatch, insert your thumb and index finger into the
cups and pinch towards the middle of the hatch. Then lift
towards one side to release one magnet and then pull up
and away from the model to release the second model.
Note: If you are not flying with floats you may wish to
cut the plastic cups out of the hatch and make two holes
for your fingers.
If you intend to fly on floats, then you may wish to leave
the cups in place.

1. Mark the wing joiner and the wing panels so the
joiner can easily be positioned consistently during the
joining of the wings.
2. Slide the wing joiner into the wing panel. Use a pencil
to mark the joiner against the wing. The joiner should fit
snug in the wing. If it does not fit, lightly sand the joiner
until it does fit nicely.
3. Slide the joiner into the opposite wing panel. It should
slide in to slightly hide the line drawn in the previous
step. If not, lightly sand the ends of the joiner until it fits
equally into both wing panels.

Note: The following steps will be performed while
you have epoxy mixed. Make sure the steps can
be performed before the epoxy begins to cure. It is
suggested to make a test run of the steps if you are
unsure of the procedure.
4. Mix up some 30-minute epoxy and apply it to one half
of the joiner. Make sure to coat the top, bottom and both
sides of the joiner.
5. Coat the root rib of the wing panel with epoxy. Apply
epoxy into the opening for the joiner as well.
6. Slide the joiner into the wing panel. Apply epoxy to
the joiner and to the wing as described in Step 5 and
slide the two wing panels together.

8. Use a sharp hobby knife to cut the covering slightly
inside the lines drawn. Be very careful not to cut into the
underlying wood, as this will weaken the stab and cause
it to fail in flight.
9. Slide the stabilizer back into position. After checking
the alignment, wick thin CA into the joint between the
fuselage and stabilizer on both the top and bottom of
the stabilizer. Also wick thin CA into the surrounding
wood on the bottom of the fuselage to increase the bond
between the fuselage and stabilizer.
Note: You can use a soldering iron instead of a knife.
This will eliminate the chances of cutting into the wood.

slightly below the lines drawn. Be very careful not to
cut into the underlying wood, as this will weaken the fin
and cause it to fail in flight. Also trim the covering on
the top of the fuselage.
13. Check that the fin is square to the stabilizer. Sanding
the bottom of the fin where it fits into the fuselage can
correct for any alignment issues. A slight amount of
material from the bottom of the fin might need to be
removed for a correct fit.

2. With the float supports resting on your work surface,
use the supplied hex wrench to tighten the four setscrews
to secure the braces in position. Keeping the supports
aganst the surface will help keep everything in alignment
while tightening the setscrews. Only tighten the setscrews
hand tight at this point.
3. Position the strap for the float mount at the corner
of the battery tray as shown. It should be as close as
possible to the battery hatch, yet not prevent the hatch
from opening. Use a drill and 5/64-inch (2mm) drill bit
to drill the holes for the front mounting straps.

4. Attach the float mount to the bottom of the fuselage
using two straps, four 3mm x 12mm sheet metal screws
and a #2 Phillips screwdriver.
5. Repeat Steps 3 and 4 for the rear mounting straps.
The main concern is the float mount is centered side to
side on the bottom of the fuselage.
6. Using threadlock, tighten the setscrews for the cross
braces on the float mount. Assemble and attach the floats
to the float mounts using the instructions provided with
your float set. The float with the water rudder installs on
the left side of the model.

7. Drill a 1/8-inch (3mm) hole in the bottom of the
fuselage near the landing gear. Route the float pushrod
through the hole and into the fuselage. Use silicone
adhesive to glue the pushrod tube to the fuselage. Use
thin CA to glue the landing gear plugs to the fuselage at
this time as well. You may also opt to use clear tape to
install the landing gear plugs in the fuselage if you might
change from floats to wheels from time to time.
8. Connect the pushrod cable to the connector. The
pushrod must be secured inside the fuselage. Wrap string
around the pushrod tube and the cross member of the
radio tray. Soak the string with thin CA to secure the
pushrod location inside the fuselage.

Control Throws
1. Turn on the transmitter and receiver of your DHC-2 Beaver.
Check the movement of the rudder using the transmitter.
When the stick is moved right, the rudder should also move
right. Reverse the direction of the servo at the transmitter if
necessary.
2. Check the movement of the elevator with the radio system.
Moving the elevator stick down will make the airplane
elevator move up.
3. Check the movement of the ailerons with the radio system.
Moving the aileron stick right will make the right aileron
move up and the left aileron move down.
4. Use a ruler to adjust the throw of the elevator, ailerons
and rudder. Adjust the position of the pushrod at the control
horn to achieve the following measurements when moving the
sticks to their endpoints.
Note: Measurements are taken at the widest point on
the surface.

Center of Gravity
Preflight
An important part of preparing the aircraft for flight is properly
balancing the model.
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location for the
DHC-2 Beaver ARF is 2
1
/
– 2
4
3
/
-inch (57–70mm) back from the
4
leading edge of the wing. Mark the location of the CG on the
bottom of the wing.
Please balance your model upright with the battery installed.
With the model upright, lift the model at the marks using your
fingertips, or use a commercially available balancing stand.
The model will rest level or slightly nose down when balanced
correctly. Adjust the position of the motor battery, or add weight
to the nose or tail if necesary to achive the correct CG.
Check Your Radio
Before going to the field, be sure that your batteries are fully
charged per the instructions included with your radio. Charge
both the transmitter and receiver pack for your airplane. Use
the recommended charger supplied with your particular radio
system, following the instructions provided with the radio. In
most cases, the radio should be charged the night before going
out flying.
Before each flying session, be sure to range check your radio.
See your radio manual for the recommended range and
instructions for your radio system. Each radio manufacturer
specifies different procedures for their radio systems. Next, start
the motor. With the model securely anchored, check the range
again. The range test should not be significantly affected. If it is,
don’t attempt to fly! Have your radio equipment checked out by
the manufacturer.
Note: Keep loose items that can get entangled in
the propeller away from the prop. These include
loose clothing, or other objects such as pencils and
screwdrivers. Especially keep your hands away from the
propeller.
After the first flights, the CG position can be adjusted for your
personal preference.
Double-check that all controls (aileron, elevator, rudder and
throttle) move in the correct direction.
Check the radio installation and make sure all the control
surfaces are moving correctly (i.e. the correct direction and with
the recommended throws). Test run the motor and make sure
it transitions smoothly from off to full throttle and back. Also
ensure the engine is installed according to the manufacturer’s
instructions, and it will operate consistently.
Check all the control horns, servo horns, and clevises to make
sure they are secure and in good condition. Replace any items
that would be considered questionable. Failure of any of these
components in flight would mean the loss of your aircraft.

Flying Your DHC-2 Beaver ARF
You will find the Beaver to be a very docile model in the air
and on the ground. Takeoff's are a piece of cake with the large
rudder and flaps. Landings are slow and gentle with the large
flap area fully deployed on final approach.
Begin by placing the model on the ground. Check all control
throws and ensure everything is traveling in the right direction.
Move your idle trim up until the prop begins to spin; this will be
your flight idle. Taxi into position on the runway, facing into the
wind. Do your first takeoff without using the flaps. Apply power
slowly and steer with rudder. The tail will come up very quickly.
As you apply full throttle and come to speed, apply a slight
amount of up elevator and the Beaver should lift off gently and
begin to climb upwards. As you climb out release the elevator
and maintain a gentle climb to about 100 feet of altitude.
Once at about 100 feet of altitude trim the model for level flight
at 5/8 throttle. You will find the Beaver to be very gentle on the
control and feel quite light on the sticks. The model is capable
of all the basic aerobatic maneuvers; loops, rolls, stall turns,
inverted flight, etc.
You will want to fly with the flaps a bit to get use to them. They
are very effective in slowing the model down on final approach.
When the desired altitude is reached, drop the flaps to the half
and then the full position. Check to see if there is any roll trim
required. If the model rolls one way or another, retract the flaps.
Land the model and adjust the flap linkage. If the model rolls
left, the right flap is down too far. If the model rolls right, the left
flap is down too far.
If you have no roll issues with the model then you are ready
to set up for landing. We normally do a pass over the runway
and drop the flaps on this pass. Turn into the downwind and
manage the power at about 1/2 throttle. As you turn to base
leg, you may reduce the throttle a bit and then when you turn
final adjust the power to maintain a shallow descent with the
model. As you come down to an altitude of about 8 feet over
the runway, begin to level the model out and as you get within
3 feet, you will begin to flare for landing. The Beaver likes to
be either landed on the mains or three pointed on the gear in
a full stall. The choice is yours. Landing without using flaps is
no different, just a bit faster on the final approach, but very
manageable.
Flying on floats is another world of fun with the Beaver. We
recommend the use of the Power 32 for float flying on 4S for
reasons of the extra weight and drag. This is where this model
really excels and is why we included the float mounts in the
kit. Taxiing out is a slow process and full up elevator should be
used to help reduce the water spray from the propeller. Once
you have lined up into the wind, apply power slowly with full
up elevator being held. As the model accelerates and comes up
on step, reduce the amount of up elevator you are holding and
allow the model to plane on the step of the floats. Once you
are here, apply up elevator in a smooth action until the model
breaks free from the water. Continue your climb out as you did
from land. If you are using half flaps for takeoff, you will find
the Beaver lifts out of the water very easily without any issues
at all. Flying is a special treat with the floats on. It is very easy
to get caught up in the look of flying through the Alaskan bush
as you cross by on a fly-by. Setting up to land is as easy as
dropping the flaps to the full position and setting up on final.
Manage your power as the floats add a fair amount of drag to
the airframe. It is common to be carrying a small bit of power
on final with the floats and full flaps. Manage the power to
control the descent and elevator to control the airspeed.
As you get closer to the water begin to flair the model and
flatten out the approach. The goal is to set the model down
on the aft edge of the floats. Once the floats hit the water, the
drag will cause the model to slow very quickly. You will want
to initially carry the up elevator you had for the flair until the
model begins to slow to a point where it will not take flight
again. Touch and gos are a graceful maneuver with the Beaver
and are a sight to see.
We at E-flite hope you enjoy your Beaver as much as we have.
Happy landings!
