Section Description Page

INTRODUCTION

Thank you for purchasing the JR Venture™ 50 3D ARF helicopter. The Venture 50 has been designed to provide the aspiring 3D Heli pilot with a model that is very reliable and durable, while featuring outstanding 3D performance and affordability. Featuring full ball bearings at all critical locations and a high quality Swashplate, the Venture 50 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 the aspiring and accomplished 3D pilot, thanks to the optional 3D control system parts and instructions included with each kit. In its stock form, the Venture is very smooth and predictable, giving the aspiring 3D 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.

SERVO INST ALLATION

RADIO INSTALLATION SUGGESTIONS

Be sure to install four rubber servo grommets and eyelets to each servo prior to installation.

When adjusting control rods, be sure to adjust each universal link the same amount so as not to unthread one link too far.

Be sure to keep all servo lead wires, etc., away from all servo arms, rods, and sharp edges of the helicopter’s mechanics. After final installation, group these wires together as indicated using the small nylon wire ties and the nylon spiral tubing included with this kit.

Note: It is suggested that the switch harness be installed prior to installation of the rudder servo.

Note: Once the servos are installed, check to see if the servos can be moved in the mounts. If the servos can be moved slightly, tighten the servo mounting screws until the servos remain in position.

Be certain when installing the gyro to the gyro mounting plate that it does not come in contact with the frame of the helicopter and that the mounting surfaces are free from oil, residue, etc. Clean if necessary to ensure proper adhesion.

Install the switch harness with the switch plate screws through the round rubber grommets before the servos are installed.

UNDERSTANDING SW ASHPLATE 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.

(C)

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%.

IMPORT ANT CCPM PROGRAMMING GUIDELINES

It is extremely important that the travel adjustment values for the three CCPM servos (aileron, elevator, AUX1) be initially set to exactly the

same travel value. If the travel value is not similar for each servo, it will create unwanted pitching and rolling of the swashplate during collective pitch inputs. The travel values for each servo will be adjusted in Steps 3-7 and 3-8 to remove any minor pitch and roll coupling during pitch, roll, and collective movements.

Minor travel value adjustments are necessary due to slight variations in servo travel and centering. Although the three servos may appear to

travel at the same amounts in each direction, in reality the servos can vary slightly. This variation is more common in analog type servos. If JR’s new digital servos are used, the travel adjustment values will generally not need to be altered.

It is also extremely important that the servo reversing directions for the three CCPM servos (aileron, elevator, AUX 1) be set as indicated in the previous radio programming steps. If one or more servos is not set to the correct direction, the CCPM function will be out of synchronization, and the three control functions (aileron, elevator, collective) will not move properly. In the event that a control surface is working in the wrong direction, the control function can only be reversed by changing the desired CCPM value for that function from a + to a - value or vise versa.

Example: If, when you increase the collective pitch, the pitch of the main blades actually decreases, it will be necessary to access the CCPM function and change the travel value for this function from + to - or - to +. This will reverse the direction of the collective pitch function without affecting the movement of the aileron and elevator functions.

The JR 120° CCPM system requires the use of three servos to operate, aileron, elevator, and AUX 1(Pitch). The labeling of these servos can become quite confusing because with the CCPM function, the three servos no longer work independently but rather as a team, and their functions are now combined. For this reason, we will refer to the three servos in the following manner:

Aileron Servo: “Left” servo (C); the channel number is CH2 when using a JR radio

Elevator Servo: “Front” servo (A); the channel number is CH3 when using a JR radio

AUX 1 (Pitch) Servo: “Right” servo (B); the channel number is CH6 when using a JR radio

CCPM SERVO ARM PREPARATION AND INST ALLA TION

2x10 mm Flat Head Screw (3)

Steel Joint Ball (3)

2 mm Hex Nut (3)

It will be necessary to prepare three servo arms as shown in the diagram below. Prior to assembling the servo arms, the servos should be centered as indicated below, and the servo arms test fitted to the servo to insure that the arms will attach to the servo as indicated. Since the JR servo arm spline uses an odd number of teeth, it is sometimes possible to rotate the servo arm 180° to achieve a more correct positioning.

Once the best direction for the servo arm has been decided, mark the servo arm with the servo it is to be connected to (F, R, or L), as well as the side of the servo arm that needs to be removed.

It is

very important that a heavy-duty type servo arm be used with the control ball location placed at exactly 20 mm as shown. For JR radio users, we recommend the JRPA215 Heavy-Duty Servo Arms included for this use. If a control ball position other than the specified 20 mm is used, this will create an adverse affect as to the travel of the swashplate, as well as unwanted control differential and interaction.

Prior to attaching the servo arm to the servo, it will be necessary to first turn on the radio system to center each of the three CCPM servos. It is important that the radio’s collective pitch stick be set at the center position. If your radio is equipped with a hover pitch knob, please check to make sure that this knob is also in the center position at this time.

Connect the three servo arms to the three CCPM servos as shown. It is important that the servo arms be positioned parallel to the servos as shown. If the servo arm is not parallel as shown, minor centering adjustments can be made using the radio’s Sub-Trim function. Please refer to Section 3-4 for more information.
