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.

Required Radio Equipment
Important Information About
You will need a minimum 6-channel transmitter (for proper
mixing and dual rate capabilities), crystals, receiver, and six mini
servos. You can choose to purchase a complete radio system.
If you are using an existing transmitter, just purchase the other
required equipment separately. We recommend the crystal-free,
interference-free Spektrum
system. If using your own transmitter, we recommend the JR
SPORT
If you own the Spektrum DX6i radio, just add the AR6200
DSM2
servos.

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.

on Power 25's and 3S Li-Po systems with plenty of power
for basic maneuvers and flight performance.
Float version: We flew the prototype Beavers on Power
32's and 4S Li-Po systems when using floats due to the
higher weight of the model with floats installed.
Mounting hardware is included for mounting either motor
combination in your Beaver.

1. Attach the X-Mount to the motor using the screws
provided with the motor and a #2 Phillips screwdriver.
Make sure to use threadlock on all four screws so they
do not vibrate loose.
2a. Attach the Power 32 motor to the firewall using four
4-40 x 1-inch socket head screws, four #4 washers, four
aluminum motor spacers. Tighten the screws using a
3/32-inch ball driver. Make sure to use threadlock on the
four screws to prevent them from vibrating loose.
2b. Attach the Power 25 motor to the firewall using four
4-40 x 1/2-inch socket head screws and four #4
washers. Tighten the screws using a 3/32-inch ball

them so they are aligned with your particular motor
before mounting it to the firewall.

3. Use hook and loop tape to mount the speed control to
the front of the battery box as shown. You will need to
attach a 9-inch extension onto the ESC plug to route it to
the receiver.
in the center of the dummy radial engine. Use a hobby
knife to remove the area between each of the cylinders to
allow cooling air to pass through the cowling and over
the motor. Use 6-minute epoxy to glue the dummy radial
engine inside the cowling. Use the following colors to
paint the dummy radial engine.
4. Plug the leads together between the motor and speed
control. Secure the wires so they will not interfere with the
operation of the motor.
Note: We used the following colors when painting
the engine:
Rocker Shafts – Aluminum
Engine Cylinders – Black
Plug Wires – Yellow
Center Crankcase – Lt. Gray
5. Use a hobby knife and rotary tool to remove the area
12 E-flite DHC-2 Beaver ARF Assembly Manual
6. Attach the cowl to the fuselage using four 4-40 x
3/8-inch socket head screws and four #4 washers.
Note the direction of the cowl as shown in the photo.
Use a 3/32-inch ball driver to tighten the screws that
secure the cowling. Use threadlock to ensure the screws
do not come loose during flight.
7. Insert the propeller adapter into the spinner backplate.
It may be necessary to enlarge to hole in the backplate to
accept the adapter.
8. Slide the adapter onto the motor shaft, then slide the
propeller onto the adapter. Use the adapter nut to secure
the propeller and spinner backplate to the motor shaft.
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.
13E-flite DHC-2 Beaver ARF Assembly Manual
9. Secure the spinner cone to the backplate with the
screws provided with the spinner. Use a #1 Phillips
screwdriver to tighten the two screws.
10. Carefully remove the hatch from the bottom of the
fuselage. It is held at the rear with two magnets. To open
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.

11. Install the battery in the fuselage using the two velcro
straps. The battery can be moved forward or rearward
to correct for the Center of Gravity if necessary. You may
also wish to use some hook and loop tape on the tray to
secure the battery from sliding fore or aft.
12. You may elect to cut a hole for exit air in the aft
area of your fuselage. You will notice we have designed
the structure so that an air exit hole may be located in
the following position. Using the batteries listed in this
manual, we found no need for an air exit hole in the
fuselage.
