INTRODUCTION
Congratulations on your purchase of the JR Voyager E Electric Heli.
This model has been designed using the latest in state-of-the-art
design technology.
To achieve the best performance and reliability from this model,
please read through these instructions carefully so you become familiar
with the contents of this kit before assembly.
JR CCPM
To take the electric heli designs to the next level, JR’s designers
turned to CCPM (Cyclic/Collective Pitch Mixing). CCPM is a unique con-
trol system that mounts three servos below the swashplate with short,
straight linkages directly to the swashplate at 120-degree intervals. With
CCPM, complex collective and cyclic mixing is accomplished electronically
rather than mechanically. As a result, many parts are eliminated, along
with excessive control system play, not to mention quicker building and
lower maintenance.
What’s more, you get more servo power from CCPM. That’s because
instead of one servo moving the collective, you now have three. Instead of
one servo moving the cyclic, you have two.
Before you begin the assembly of your Voyager E, we suggest that
you first review the entire instruction manual to become familiar with the
assembly sequences and parts layout.
WARNING
The radio-controlled model helicopter contained in this kit is not a
toy, but a sophisticated piece of equipment. This product is not recom-
mended for use by children. Radio-controlled models such as this are
capable of causing both property damage and/or bodily harm to both the
operator/assembler and/or spectator if not properly assembled and operat-
ed. Horizon Hobby, Inc. assumes no liability for damage that could occur
from the assembly and/or use/misuse of this product.
Although the Voyager E is powered by a quiet, smooth-running elec-
tric motor, it should be assembled and operated with the same care as its
larger glow engine counterparts. When operating your Voyager E, please
exercise caution and safety.
Becoming a successful RC helicopter pilots takes many hours of
preparation and practice. When watching an experienced RC helicopter
pilot flying, it may appear that they are very easy to fly, when in reality it
will take many hours to develop these flying skills.
Please understand that it requires hours of practice to master the art
of RC helicopter flying. On initial flights with your Voyager E, please begin
by attempting simple hovering maneuvers only until you become comfort-
able with the operation of this model. If possible, please seek help from an
experienced RC heli pilot for guidance. With a little time and patience, you
will be able to achieve the full satisfaction of RC helicopter flying.
USE SAFETY AND CAUTION WHEN OPERATING
An electric-powered heli is different from a conventional glow-pow-
ered model in that it can possibly activate the motor as soon as the NiCad
battery is connected if the proper procedures and adjustments have not
been followed.
Please follow the connection and adjustment instructions carefully
during assembly. Use caution and care when handling the NiCad battery to
avoid and prevent any possibility of reverse polarity or shorting, as dam-
age to the electronic equipment can occur.
AMA INFORMATION
We strongly encourage all prospective and current R/C aircraft pilots
to join the Academy of Model Aeronautics. The AMA is a nonprofit organi-
zation that provides services to model aircraft pilots. As an AMA member,
you will receive a monthly magazine entitled Model Aviation, as well as a
liability insurance plan to cover against possible accident or injury. All
AMA charter aircraft clubs require individuals to hold a current AMA sport-
ing license prior to operation of their models. For further information, con-
tact the AMA at:

PREASSEMBLY INFORMATION
When first opening your Voyager E kit, you will notice that all of the
parts are packaged and numbered to coordinate with the assembly step
numbers of this instruction manual.
All small hardware (nuts, bolts, washers, etc.) for each step are pack-
aged separately within the main parts bags. When beginning a section, you
will need to open only the bag with the corresponding number to the sec-
tion you are about to start. It is suggested that you place all of the hard-
ware in an open container (e.g., coffee can) during assembly so as not to
lose any of the small parts. It may also be helpful to familiarize yourself
with the various sizes of screws, bolts, nuts, etc., as illustrated in the
appropriate assembly section before you begin assembly. In most cases, at
the end of each assembly section, there should be no parts remaining.
Great care has been taken in filling the bags with the correct quantity
of parts and hardware for each section. However, occasional mistakes hap-
pen. In the event that you find a parts shortage or are in need of technical
assistance, please contact your local JR heli division parts dealer or con-
tact the Horizon Service Center directly.

when completed.
Lift the main shaft collar upwards
and secure to the main shaft
using the 2 set screws. It will be
necessary to align these set screws so that they
are accessible through the hole in the side of the
main frame. While securing the set screws,
make sure that you are pushing down on the
main rotor shaft so that there will be no up/down
play in the main shaft once the collar is secured.
Slide the swashplate assembly and the
washout assembly onto the main rotor
shaft. Next, install the antirotation plate
so that the long pin located on the lower
swashplate ring engages into the grove
of the plate as shown.

Refer to the diagram below to adjust the position of the flybar for proper
centering. Center the flybar in the seesaw shaft so that the measurement
of positions A and B are exactly the same (approx. 104 mm). Be sure
not to over tighten the set screw, 3 x 4 mm (temporarily secured in
Step 3-3) when permanently securing, as it could damage the flybar
control arm assembly.
Flybar Adjustment
Control Rod Installation
Check to insure that 2 flybar
paddles and flybar control
arms are all parallel to each
other as shown.
Flybar paddles and flybar control arm
should be parallel at this time.
Thread the universal links onto the threaded rods to the correct
lengths as shown in diagrams B and C. Please check to insure the
correct direction of the universal links as shown in the diagram,
so that the letters “JR PROPO”face the correct direction as
shown. Next, install the control rods as shown so that the letters
“JR PROPO”are facing outward.
Test the movement of the universal links to be sure that they move
freely, without a large amount of resistance or play. If the links
move tightly, it will be necessary to modify the universal link with
the optional JR ball link sizing tool. This procedure is very
important to insure the best flight performance.
Universal Link S (short) has gaps at the edge
on one side only. Install these links so this side
faces the joint ball.

When securing the pinion gear, be sure
that the 3 x 3 mm set screw engages the
flat spot of the motor shaft.
Motor Installation
When installing the motor, it will be
necessary to pass the socket head
bolt through the hole on the interme-
diate gear. Next, adjust the gear back-
lash and secure the bolts completely
using Threadlock.
Adjust the gear backlash
before securing the 3 x 3 mm
socket head screw.
Gear Backlash Adjustment: For smooth
operation and performance, it is necessary to
adjust the gear backlash properly. Excess gear
backlash can cause premature gear wear and
damage. Insufficient gear backlash can cause
vibration, as well as overheating of the motor
and speed controller. Adjust the gear backlash
by placing one piece of paper between the
gears to set the distance. When the bolts are
secure, remove the paper and test the gear
backlash to insure that there is a slight amount
of free movement between the gears.
Important Note: Once the
gear backlash has been adjust-
ed, loosen the pinion gear set
screw and raise the pinion
gear so that it no longer
engages the intermediate gear.
This procedure must be
observed to prevent accidental
blade start-up during initial
radio setup and adjustment.

Servo Installation and Linkage Suggestions
•Use caution not to overtighten the servo mounting screws. The servos
should be able to be moved slightly within the grommets so that they
have a slight amount of
vibration absorption.
•Note the correct direction of the servo output shaft as shown in the
diagrams. If the servos are installed in the incorrect direction, the
linkages will not connect properly.
•Check to insure that all control rods have been adjusted to the proper
lengths as shown in the manual.
•Install the receiver, gyro, and speed controller using double-sided servo
tape as suggested. Please make sure that the cases of these components
do not come in direct contact with other parts of the model.
•Bundle all wires neatly using nylon ties as recommended. Check to
make sure that they cannot become tangled in the gearing or moving
control system parts of the model.
Note: Fit the long flanged portion of the servo
mounting plate B into the rubber servo grommets.
