Setup Guide

1. Unpacking: Carefully remove all components from the packaging. Inspect for any damage.
2. Battery Charging:
   Connect the provided USB charging cable to the smart battery and a suitable USB power source (e.g., computer USB port, USB wall adapter). The charging time is approximately 60-70 minutes. Ensure the battery is fully charged before the first flight.
3. Install Helicopter Battery:
   Open the battery compartment on the helicopter and securely insert the charged LI-POLY 7.4V (1200mAh) 25C battery. Close the compartment.
4. Remote Control Battery Installation:
   The remote control requires batteries (not included). Open the battery compartment on the remote control and insert the required batteries (typically AA batteries, refer to remote control manual for exact type and quantity).
5. Propeller Installation (if not pre-installed):
   Attach the main and tail propellers as indicated in the manual or diagrams. Ensure they are securely fastened and oriented correctly.
6. Power On Sequence:
   
   • First, turn on the remote control.
   • Then, turn on the helicopter.
7. Binding (Pairing) the Remote Control:
   The helicopter and remote control should automatically bind when powered on in sequence. If binding fails, refer to the remote control diagram for the frequency binding button. Typically, this involves holding a button on the remote while powering it on, or pressing a bind button on the helicopter while it's searching for a signal.
8. Pre-Flight Check:
   Before each flight, ensure all parts are secure, propellers spin freely, and the battery is fully charged. Check that all control surfaces respond correctly to remote control inputs.

Operating Instructions

Basic Flight Controls

Figure 10: Basic Flight Functions

• Upwards/Downwards (Throttle): Use the left joystick (Mode 2) or right joystick (Mode 1) to control the helicopter's altitude. Push up to ascend, pull down to descend.
• Left/Right Flight (Aileron): Use the right joystick (Mode 2) or left joystick (Mode 1) to move the helicopter sideways. Push left to fly left, push right to fly right.
• Turn Left/Right (Rudder): Use the left joystick (Mode 2) or right joystick (Mode 1) to rotate the helicopter on its vertical axis. Push left to turn left, push right to turn right.
• Forwards/Backwards (Elevator): Use the right joystick (Mode 2) or left joystick (Mode 1) to move the helicopter forwards or backwards. Push up to fly forwards, pull down to fly backwards.

Special Flight Functions

• One-Touch Landing: Press the dedicated "One Touch Landing" button on the remote control for an easy and controlled descent and landing. This feature simplifies landing for beginners.
  

  Figure 11: One-Touch Landing

• Altitude Hold: The helicopter automatically maintains a set altitude using air pressure sensors and GPS data, allowing for stable hovering.
• Optical Flow Positioning: Utilizes a downward-facing camera to detect ground patterns, providing precise positioning for stable flight, especially in indoor environments or at lower altitudes outdoors.
• One-Touch Inverted Flight Mode: This intelligent feature allows the helicopter to perform inverted flight with a single button press. The controls for inverted flight are the same as for forward flight, making it easier to learn. Practice this mode outdoors in an open field with no or light wind.

• Controller Mode Conversion (MODE1/MODE2): The remote control supports switching between MODE1 and MODE2. Refer to Figure 9 for the location of the conversion button.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the helicopter after each flight. Avoid using solvents or harsh chemicals.
• Propeller Inspection: Regularly check main and tail propellers for any cracks, bends, or damage. Replace damaged propellers immediately to ensure safe and stable flight.
• Motor Care: Keep motors free from dust and debris. Avoid prolonged operation in dusty environments.
• Battery Care:
  • Always charge the battery using the provided USB cable.
  • Do not overcharge or over-discharge the battery.
  • Store batteries in a cool, dry place away from direct sunlight and extreme temperatures.
  • If the helicopter will not be used for an extended period, charge the battery to approximately 50% for storage.
• General Inspection: Periodically check all screws and connections to ensure they are tight and secure.

Troubleshooting

User Tips

• Understanding GPS Functionality: The Eachine E190 features "GPS Altitude Hold" and "Optical Flow Positioning." This means it uses GPS data to assist in maintaining a stable altitude and optical flow for precise horizontal positioning, especially useful for hovering. It does not imply full GPS navigation or waypoint programming typically found in higher-end drones.
• Outdoor Flight Conditions: While the helicopter has good anti-wind ability (Level 5 Super Wind Resistant), for optimal performance and especially when practicing advanced maneuvers like inverted flight, choose an open outdoor area with minimal wind.
• Battery Management: Always allow the battery to cool down before recharging it after a flight. This helps prolong battery life.
• Pre-Flight Check: A quick visual inspection of propellers, landing gear, and battery connection before each flight can prevent many common issues.
