Eachine E52 Drone User Manual and Flight Guide

Important Safety Information and Warnings

WARNING

Please read the following instructions carefully before operating the drone. Improper use can lead to injury or damage.

• This product is not a toy and is intended for users aged 14 and above.
• Always operate in a safe, open area, away from people, animals, and obstacles.
• Do not fly near airports, power lines, or other restricted areas.
• Keep the drone within visual line of sight at all times.
• Do not fly in adverse weather conditions such as rain, strong winds, or snow.
• Ensure the drone's battery is properly charged and installed.
• Handle the Li-Po battery with care, following all safety guidelines.

Aircraft Components

The drone includes the following key components:

• Blade: Rotates to provide lift and thrust.
• LED Light: Indicates drone status.
• Li-Po Battery: Powers the drone.

Remote Controller Instructions

The remote controller allows you to operate the drone. It features:

• High/Low Speed Switch: Adjusts the drone's flight speed.
• Take a Photo: Captures still images.
• Video: Records video footage.
• ON/OFF Switch: Powers the controller on and off.

Transmitter Battery Instruction

The remote controller requires 4 AA batteries.

1. Open the battery cover on the back of the controller.
2. Insert 4 AA batteries, ensuring correct polarity (+ and -) as indicated.

Beginner Operation Tip: For beginners, it is recommended to set the accelerating scope on the transmitter between 40%-60% (Small Action Mode). Adjust this percentage based on your operating proficiency.

Modes: The controller supports different modes, typically referred to as Mode 1 and Mode 2, which dictate the function of the control sticks. This manual primarily illustrates Mode 2 controls:

• Left Control Lever (Throttle/Yaw):
  • Push Up: Ascent (Drone moves upwards)
  • Push Down: Descent (Drone moves downwards)
  • Push Left: Yaw Left (Drone rotates counter-clockwise)
  • Push Right: Yaw Right (Drone rotates clockwise)
• Right Control Lever (Pitch/Roll):
  • Push Forward: Fly Forward (Drone moves forward)
  • Push Backward: Fly Backward (Drone moves backward)
  • Push Left: Fly Left (Drone moves left)
  • Push Right: Fly Right (Drone moves right)

Flight Safety and Hovering

Before attempting advanced maneuvers, practice basic flight stability:

• Ensure the flight area is clear of people and obstructions.
• Practice hovering: Keep the drone in a fixed position in mid-air. This is a fundamental skill for safe flight.
• Maintain a safe distance: Stand approximately 2 meters diagonally behind the flight vehicle during initial hovering practice.

Auto-Calibration for Stability: If the drone is unstable or drifts during hovering and cannot be trimmed, place it on a horizontal surface. Simultaneously push the left throttle stick to the bottom-left and the right throttle stick to the bottom-right until the drone's lights flash and the remote controller beeps rapidly. This action recalibrates the drone for stable flight.

Trim Adjustments

Trimming allows you to correct minor drifts or rotations during flight.

General Trimming Procedure: Slowly raise the throttle stick until the drone lifts off slightly. Use the trim buttons to correct any leaning or drifting.

1. Rudder Trim (Yaw Correction):

   Adjusts for nose left/right lean. If the nose leans right, press the left trim button. If the nose leans left, press the right trim button.

2. Direction Rudder Trim (Pitch Correction):

   Adjusts for forward/backward drift. If the drone flies forward, adjust the trim downwards. If it flies backward, adjust the trim upwards.

   [Illustration: Shows forward/backward trim buttons affecting forward/backward movement]

3. Aileron Trim (Roll Correction):

   Adjusts for body left/right lean. If the body leans right, press the left trim button. If the body leans left, press the right trim button.

Special Flight Functions

Flipping Function (360° Tumbling)

To perform a flip, press the Tumbling Key on the right control lever. Then, push the direction lever in any direction (Left, Right, Forward, or Backward) to execute a 360-degree roll in that direction.

Headless Mode

When the drone is flying forward, briefly press down on the throttle stick. The drone enters Headless Mode, allowing it to fly freely without being limited by its own orientation. The front of the drone will always be the direction you are controlling from, regardless of the drone's actual facing.

One-Key-Return Function

If you lose track of the drone's direction, keep the throttle stick pressed down. The drone will activate the One-Key-Return mode and fly back towards the remote controller's location. Once it returns, you can resume control by pushing the throttle stick.

Troubleshooting During Flight

Refer to the following table for common flight issues and solutions:

Pre-Flight Preparation

1. Propeller Installation

Install propellers accurately. The propeller marked 'A' should be installed on arm 'A'. For other propellers, ensure they are installed in the opposite direction of rotation relative to their marked arm. Align the propeller with the steel shaft on the arm and press down into the propeller hole. Do not apply excessive force, as this can deform or damage the propeller.

2. Arms Folding Order

To fold the arms: first fold the front arms (near the camera), then fold the back arms. To unfold, reverse this order.

3. Lithium Battery Instruction

To remove the battery: Hold down the battery spring button and gently pull out the battery. To charge:

1. Connect the charger plug to a computer USB port.
2. Plug the charger's red connector into the battery port, observing the correct positive (+) and negative (-) polarity. Do not insert in the opposite direction.
3. The USB indicator light will be on during charging. It turns off when the battery is fully charged. Charging time is approximately 90 minutes.
4. For safety, keep the battery in your line of sight while charging.

When assembling the battery, ensure correct orientation and gently press it into place until it clicks securely.

4. Attentions to Lithium Battery Usage

Lithium batteries carry inherent risks, including fire, injury, or property loss. Users must be aware of these risks. Manufacturers, retailers, and dealers are not responsible for accidents resulting from misuse. Please read safety guidelines and charging instructions carefully.

• Leakage: If battery leakage occurs, avoid contact with eyes and skin. If contact occurs, wash eyes with clean water and seek immediate medical attention.
• Abnormalities: If you detect any peculiar smell, noise, or smoke, immediately remove the battery plug.
• Safety Compliance: Strictly adhere to the following to prevent fire, electric shock, or explosion:
  • Use only the original factory charger.
  • Do not charge swollen or worn-out batteries.
  • Do not overcharge; disconnect the charger once fully charged.
  • Do not charge near flammable materials or conductive surfaces. Monitor the battery during charging.
  • Do not charge batteries that have not cooled down.
  • Charging temperature should be between 0°C and 40°C.
• Recycle: Do not dispose of electronic equipment or batteries as household waste. Use designated containers for damaged/unusable batteries. Dispose of electronic waste according to special requirements and local methods.
