A 3-Channel Multi Servo Tester with Consistency Speed Controller and CCPM (Cyclic Collective Pitch Mixing) is a specialized electronic controller often used in model aircraft or drones, especially for controlling servo motors in systems like RC helicopters or RC planes. This controller helps to fine-tune and adjust the speed and movement of servos across different channels in the system.

Here’s a detailed breakdown of its functions and features:

Key Features of a 3-Channel Multi Servo Tester:

1. Three Channels:

   • This type of servo tester can control up to three individual servo motors simultaneously, typically used to control different functions or axes in a model (such as elevator, rudder, and aileron in an RC plane).
   • It allows independent control of each servo on its respective channel, providing a wide range of flexibility in multi-servo setups, especially in models like airplanes, helicopters, or boats.

2. Servo Speed Control:

   • The tester allows for speed control of the servos. This means you can adjust how fast the servos move from one position to another. This is particularly useful for controlling the responsiveness of the servos, making them move slowly or quickly depending on your preferences.
   • Speed control is typically implemented using a potentiometer or a digital knob, which allows smooth adjustments to servo motion speed.

3. Consistency Control:

   • This refers to the ability of the tester to maintain consistent movement across all servos in terms of timing and synchronization. Ensuring all servos perform the same movements with no discrepancy is important in certain control setups like multi-rotor drones, where precise movement is required.

4. CCPM (Cyclic Collective Pitch Mixing):

   • CCPM is a feature commonly used in RC helicopters, where multiple servos control a single function like the pitch of the rotor blades. In CCPM, the control inputs for the collective pitch (which changes the angle of all blades simultaneously) and the cyclic pitch (which changes the angle of individual blades depending on their position in the rotation cycle) are mixed together.
   • This type of mixing requires multiple servos to work together to adjust the rotor blade angles in a way that the helicopter can perform different movements (e.g., rolling, pitching, and yawing). A 3-channel servo tester with CCPM would mix the servo inputs accordingly, allowing the helicopter to perform coordinated movements.

5. Channel Switching and Customization:

   • Depending on the model, you may have the ability to change how each channel is mapped to specific servos, allowing for customized setups. For example, you could map one channel to control the aileron and another to control the rudder, or adjust based on CCPM requirements in a multi-servo system.

6. LED or LCD Display:

   • Some 3-channel servo testers come with an LED or LCD display that shows real-time information about servo position, speed, and control status, providing valuable feedback to users for adjustments.

Typical Applications of a 3-Channel Multi Servo Tester with Speed Control and CCPM:

1. RC Helicopters (CCPM):

   • As mentioned, this controller is widely used in RC helicopters where multiple servos are used to control the pitch of rotor blades. The CCPM feature ensures that the servos work together in a coordinated fashion for precise flight control.

2. RC Planes:

   • In RC planes, a 3-channel servo tester can be used for controlling the elevator, aileron, and rudder servos. The speed control allows fine-tuning the responsiveness of control surfaces, which can make a plane easier or more challenging to fly based on user preference.

3. Drones and Quadcopters:

   • While drones usually use more than 3 channels, a 3-channel tester could be used for smaller drones or for testing individual servo movement in components like gimbals, camera mounts, or tilt/roll mechanisms.

4. Testing and Tuning Servos:

   • A servo tester is an essential tool for bench testing servos before integrating them into the system. It ensures that all the servos respond correctly and consistently to commands. The speed control is useful for adjusting servo responsiveness during testing.

5. Custom Robots:

   • For robots with multiple servo actuators, especially those requiring coordinated movements across different joints or appendages, a 3-channel servo tester can help tune the servo performance.

How It Works:

1. Input Signal:

   • The device typically receives PWM (Pulse Width Modulation) signals to control the servos. PWM controls the position of the servo based on the length of the pulse. The speed control adjusts the rate at which the servo moves between different positions.

2. Adjusting Speed:

   • Using the speed adjustment dial or control on the tester, you can increase or decrease the time it takes for the servo to travel between its minimum and maximum positions. This is useful for slowing down the movement for more delicate tasks or speeding it up for faster responses.

3. Mixing for CCPM:

   • When operating in CCPM mode, the tester will take the collective and cyclic pitch inputs and mix them to control multiple servos simultaneously. The mixing might involve altering the timing and angles of the individual servos to create a coordinated movement in the rotor blades of a helicopter.

Example Setup:

• For a 3-Channel RC Helicopter:
  • Channel 1: Controls the elevator (pitch of the helicopter).
  • Channel 2: Controls the aileron (roll control).
  • Channel 3: Controls the rudder (yaw control).
  • CCPM Mixing: Ensures that the servos operate together to adjust the rotor blade angles for collective and cyclic pitch control.

Example Setup for Testing Servos:

1. Connect the servo tester to a power source (typically a 5V or 6V DC supply).
2. Connect the servos to the three output channels (usually labeled Channel 1, Channel 2, and Channel 3).
3. Adjust the speed control to test how fast each servo moves through its range.
4. Use the CCPM mode for coordinated servo control in a helicopter setup.

Conclusion:

A 3-Channel Multi Servo Tester with Consistency Speed Controller and CCPM Mixing is an essential tool for controlling and testing multiple servos, especially in complex systems like RC helicopters, RC planes, or drones. The speed control allows you to adjust the responsiveness of the servos, while CCPM ensures that multiple servos work in harmony for cyclic and collective pitch adjustments. Whether you are building or fine-tuning a model aircraft or testing individual servos for accuracy and performance, this device provides versatility and precision control.
