INTRODUCTION
Thank you for purchasing the JR Venture™30 CP ARF helicopter. The Venture has
been designed to provide the aspiring heli pilot with a model that is very reliable ,
durable, and easy to maintain. Featuring full ball bearings at all critical locations,
the Venture will retain its precision and reliability through many flights. The
Venture’s unique two-piece box frame design adds rigidity to the model, while
keeping the weight and parts count to a minimum. The Venture is equally suited for
both beginning and advanced 3D pilots, thanks to the optional 3D control system
parts and instructions included with each kit. In its stock form, the Venture is very
stable, giving the beginning heli pilot an additional step to success.
JR CCPM
To take the Venture's design to the next level, JR’s designers turned to CCPM
(Cyclic/Collective Pitch Mixing). CCPM is a unique control 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 Venture 30 CP, 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 recommended 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 operated. Horizon Hobby, Inc. assumes
no liability for damage that could occur from the assembly and/or use/misuse of
this product.
AMA Information

Preassembly Information
All small hardware (nuts, bolts, washers, etc.) for each step are separated and
packaged separately within the main parts bags. It is suggested that you place all of
the hardware 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, occasionally mistakes do happen. 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 the Horizon Service Center directly.

UNDERSTANDING SWASHPLATE CONTROL SYSTEMS
Currently, there are several different types of control systems available on the market. Although the mechanical methods for
transferring control to the swashplate vary, the different control systems can be broken down into two categories:
One-Servo (Conventional)
CCPM (Cyclic/Collective Pitch Mixing)
The following is an explanation of the two most popular types of swashplate control.
One-Servo Standard Swashplate Control (Conventional Helicopter)
The One-Servo standard system is found in a wide variety of radio
controlled helicopters. The term “One-Servo”means that the control
system requires one servo to operate each separate swashplate
function. With this system, a total of three servos is required to operate
the three main swashplate functions, which are aileron (roll), elevator
(pitch), and collective functions. With this type of control system, each
servo works independently and is assigned to a specific function. In
other words, the aileron (roll) servo is assigned to move only the aileron
(roll) function, as is the elevator (pitch) servo, etc. Since these servos
operate completely independently of each other, the servo torque to
each control surface is limited to the maximum torque rating of the
servos used.
The One-Servo standard system swashplate is designed so that the
lower swashplate ring control balls are spaced at 90°to each other. This
system is also most commonly arranged so that the aileron (roll) axis of
the swashplate is positioned at 90°to the main mechanics of the
helicopter, and the elevator (pitch) axis is parallel to the mechanics.
Please refer to the diagram at right for clarification.
With this type of system, it is necessary for the helicopter to be designed using an intermediate mechanical mixing system so that
the control inputs can be transferred from the three independent servos to the swashplate in such a manner that the three controls can
be achieved. This mechanical mixing system allows the swashplate to both roll (aileron) and pitch (elevator), as well as slide up and
down the main rotor shaft for collective pitch inputs. These mechanical mixing systems generally require the use of many ball bearings
and control rods to achieve this result.

120 Three-Servo CCPM Swashplate Mixing (Venture 30 CP)
The JR 120°CCPM or Cyclic/Collective Pitch Mixing, system offers the user a control system that can accomplish the same control
inputs as the One-Servo standard system mentioned above, but with increased precision and reduced complexity.
As with the One-Servo system, the JR CCPM system utilizes three servos for the three main controls: aileron (roll), elevator(pitch) and
collective. The CCPM lower swashplate ring is designed with only three control balls, spaced at 120°from each other, hence the 120°CCPM
designation. Although the control balls are not at 90°as in the standard system, the aileron (roll) axis is still parallel to the main mechanics
of the helicopter, and the elevator (pitch) axis still functions at 90°to the mechanics as does the One-Servo system. Please refer to the
diagram below for clarification.
The main and important difference in the way that these two systems operate is that unlike the One-Servo system where the three
servos work completely independent from each other, the CCPM systems work as a team to achieve the same control inputs. For example, if
an aileron (roll) input is given, two servos work together to move the swashplate left and right. If an elevator (pitch) input is given, all three
servos work together to move the swashplate fore and aft. For collective, it’s also the strength of three servos that will move the swashplate
up and down the main rotor shaft. With two to three servos working at the same time during any given control input, servo torque is
maximized and servo centering is also increased. In addition to these benefits, CCPM achieves these control responses without the need
for complex mechanical mixing systems that require many more control rods and parts to set up.
This amazing CCPM control is achieved through special CCPM swashplate mixing that is preprogrammed into many of today’s popular
radio systems. Since the 120°CCPM function is preprogrammed, CCPM is no more complicated to set up than a conventional one-servo
standard system. When you factor in the reduced parts count and easy programming, CCPM is actually easier to set up and operate than
many conventional systems.
For JR radio owners, please refer to the radio information contained at the front of this manual or on the following page to determine if
your radio system has the CCPM function. For other brands of radio systems, please contact the radio manufacturer for CCPM information.
Please note that it is not possible to program a non-CCPM radio system for CCPM operation.

JR 120°Three-Servo CCPM relies on the radio’s special CCPM swashplate mixing, rather than a conventional mechanical mixer that is
utilized to achieve the same results.
The radio’s 120°Three-Servo CCPM function automatically mixes the three servos to provide the correct mixing inputs for aileron
(roll), elevator (pitch), and collective. The following is an example of how each control input affects the servo’s movement:
1. Collective
When a collective pitch input is given, all three servos (A, B, and C) move together in the same direction, at equal amounts, to raise
and lower the swashplate while keeping the swashplate level. During this function, all three servos travel at the same value (100%) so
that the swashplate can remain level during the increase and decrease in pitch. This mixing of the three servos is achieved through the
radio’s CCPM program.
2. Elevator (Pitch)
When an elevator input is given, all three servos must move to tilt the swashplate
fore and aft, but their directions vary. The two rear servos (B and C) move together in
the same direction, while the front servo (A) moves in the opposite direction. For
example, when an up elevator (back cyclic) command is given, the two rear servos (B
and C) will move downward, while the front servo (A) moves upward so that the
swashplate will tilt aft. During this function, the front servo (A) travels at 100%, while
the two rear servos (B and C) travel at 50% (1/2 the travel value) of the front servo.
This difference in travel is necessary due to the fact that the position of the front
control ball is two times the distance of the two rear control ball position as measured
from the center of the swashplate. As mentioned, this mixing of the three servos is
also achieved through the radio’s CCPM program.
3. Aileron (Roll)
When an aileron (roll) input is given, the two rear servos (B and C) travel in opposite directions, while the front servo (A) remains
motionless. For example, when a left aileron (roll) command is given, the left rear servo (C) will move downward, while the right rear
servo (B) will move upward to tilt the swashplate to the left. As mentioned, the front servo (A) will remain motionless. The travel value
for each of the two rear servos is 100%.

CCPM SOFTWARE ACTIVATION AND INITIAL ADJUSTMENT
The following activation and setup procedure should be used for all JR XP652 and XP662 systems. Please note that the XF622 and XP642
6-channel systems do not have the required CCPM software and therefore cannot be activated by the Horizon Service Center.
Prior to activating the CCPM function, it is first suggested that the Data Reset function be performed to reset the desired model number to
be used back to the factory default settings. If you are using a new radio system, proceed to Step C.
Caution: Prior to performing the Data Reset function, it will be necessary to select the desired model number to be used.
A) Press the Mode (scroll) and Channel keys simultaneously while turning the power switch
on to enter the System Mode. Next, press the Channel key until “MDL”(Model Select)
appears on the screen, and choose the desired model number to be used.
B) Press the Mode (scroll) key until “RST”(Data Reset) appears on the screen. Press the
(+) and (-) keys simultaneously to reset the current model. A high-pitched beep will
indicate that the reset was successful. Press the Mode and Channel keys simultaneously
to exit the system mode.
C) With the power switch still on, press the Mode (scroll) and Channel keys simultaneously
to enter the function mode. Press the Mode key until “MIX CCP”(CCPM mixing) appears
on the screen. Press the (+) or (-) keys to activate the CCPM function. “MIX CP2”should
appear on the screen. It will be necessary to change the value of CP2, CP3, and CP6 to the
values as shown below.
D) Press the Mode (scroll) key until the servo reversing screen appears on the screen. Next, reverse the aileron (AIL) and rudder (RUD)
channels by pressing the Channel key to select the desired channel, and then the (+) or (-) keys to set the servo direction.
E) Press the Mode (scroll) key until “TRV ADJ”(Travel Adjust) appears on the screen, and adjust the travel values as shown by pressing the
Channel key to select the desired channel, and then the (+) or (-) key to set the desired travel value. Press the Mode (scroll) and Channel
keys simultaneously or turn the power switch off to exit the function mode. Please note that the throttle travel values may vary based
upon the type of engine used. This value can be fine tuned once the throttle linkage has been installed.
Note: The travel values shown for the rudder function are for use with Piezo gyros, like the JR G410T and G460T type gyros.
