Installation and Setup

Install Mushroom Antenna

Install the mushroom antenna to the mounting brackets as shown. Please install the mushroom antenna of the transmitter before powering on the aircraft.

Install Propeller

Fix the 4045R propeller (Clockwise rotation) onto motors M1 and M4 (CW motors) using the Red propeller adapter. Fix the 4045 propeller (Counterclockwise rotation) onto motors M2 and M3 (CCW motors) using the Black propeller adapter.

To tighten the Red propeller adapter, turn it counterclockwise. To tighten the Black propeller adapter, turn it clockwise. Ensure the propeller adapter is manually tightened and the propeller is securely installed.

Attention: Install props by hand and tighten by holding the motor with the included wrench. A wrench can also be used to remove broken props after a crash.

Battery Installation

Place the battery anti-slip mat into the battery compartment. Position the battery on top of the aircraft, adjusting it forward or backward for optimal balance without interfering with other equipment. Secure the battery firmly using the provided velcro strap.

Diagram Description: Shows the drone with the battery being placed and secured with a velcro strap in the battery compartment.

Flight Preparation

Attention Before Flight

• The EB 185 mini-quad is recommended for pilots aged 14 years or older with RC hobby experience.
• Fly only in dry weather with low wind. Avoid flying in rain or heavy foggy conditions.
• Always choose large, open fields for flying and check local laws and ordinances for legal flying areas.
• Maintain at least a 10-foot distance from the aircraft when armed to avoid injury from high-speed propellers.
• Always disarm the aircraft before handling it, whether on the ground or in flight.
• Do not fly near high-voltage power lines, cell phone towers, or radio towers, as these may disrupt your control signal.
• ALWAYS check local laws BEFORE flying. NEVER fly over crowds, concerts, or sports stadiums.

Charge the Battery

1. Insert the LiPo battery balance plug into the B3 Compact charger.
2. Connect the power cable to a wall outlet. The B3 Compact charger accepts voltages from 110V to 240V.
3. When correctly powered, the charger LED will flash orange.
4. During charging, the LED will be solid RED. When charging is completed, the charger will display a solid GREEN LED.

Diagram Description: A simple connection diagram showing a "Power supply" connected to a "B3 Compact charger", which is then connected to an "11.1V LiPo battery" via its balance plug.

Attention:

1. If the Red LED light flashes, there may be an issue with the charger or battery; stop charging immediately.
2. This charger is ONLY for charging 2S and 3S batteries. NEVER attempt to charge more than ONE battery at a time, as this may damage the charger or cause a fire.
3. During charging, place the charger in a dry, ventilated area, away from heat sources and flammable or explosive substances.
4. Always allow the battery to cool down for at least 10 minutes before charging. Overheated batteries may swell or catch fire during charging.
5. DO NOT charge a damaged battery. If the battery has cuts, swelling, or is bent, do not charge it.

Ready for Flight

1. Place the aircraft in a wide open space with the rear facing you (known as "TAIL IN" position).
2. Set the SWB switch to position 2. If using a different remote controller, set the flight model to stabilize.
3. Set all trims and dials to the middle position and move the throttle to the lowest position. Then, turn on the Remote Controller.
4. Video receiving equipment (such as an FPV monitor with a 5.8G wireless video receiver or FPV goggles) is needed to display the image and OSD information.
5. The EB 185 mini-quad features a low-voltage alarm beeper. The OSD provides visual feedback on remaining battery power, flight time, altitude, attitude line, flight speed, coordinates, and direction. When the voltage drops below 10.5 volts, the beeper will sound an alarm. The EB 185 is designed for FPV racing and does not have an "automatic landing mode".

WARNING: Do not hesitate to land when you hear the beeper alarm or see the OSD indicating 10.5 volts.

OSD Information:

The OSD information is visible on your video receiver, FPV goggles, or screen with a video receiver. It typically displays:

• Latitude and Longitude
• GPS Status
• Flight Mode (e.g., STAB)
• Speed (km/h)
• Altitude (m)
• Direction
• Battery Voltage (e.g., 11.9V)
• Aircraft Status (e.g., DISARMED)
• Flight Time (e.g., 0:00)

Binding of the EB 185

1. Turn on the Remote Controller.
2. Place the aircraft on a horizontal surface and connect the aircraft power. The left red LED light on the aircraft should turn on. Ensure positive and negative connections are correct.

Diagram Description: Shows the remote controller and the drone. Arrows indicate connecting the aircraft power, resulting in a red LED light turning on the aircraft.

Motor Control

Motor Unlock

After binding the remote controller to the EB 185, ensure all trims are neutral and the throttle stick is all the way down (displaying 0% throttle). Gently push the throttle stick down and move the rudder (YAW) stick to the right side and hold for more than 2 seconds. (In MODE 2, throttle and rudder are on the same stick). You will see two LED lights remain blue, and the buzzer will emit a long "B" sound, indicating the motors are unlocked. Be cautious, as pushing the throttle up will now start the motors. You can test this by gently pushing the stick up; the motors should start.

Diagram Description: Illustrates stick movements for unlocking motors in both MODE 1 (Throttle on right) and MODE 2 (Throttle on left). It shows the ELEV/Rudder stick and Throttle stick/Throttle/Rudder stick.

Motor Lock

To lock the motors, move the throttle stick all the way down and the rudder (YAW) stick all the way to the left. The two LED lights will remain green, and the buzzer will issue a "B~B" sound when the motors are disarmed. TEST: Push the throttle stick up slightly; the motors will not start when locked. NOTICE: The motors are LOCKED by default after successful binding.

Flying and Ending Flight

Proximity FPV Obstacle Flying

Proximity FPV obstacle flying is more suitable for experienced pilots. High-speed obstacle avoidance flights require advanced skills.

• Recommended FPV range is 300m, depending on the environment.
• Avoid flying over people or animals. Do not fly over crowds, concerts, or sports stadiums.
• Avoid flying close to power lines and cellphone towers, as these may cause crashes.

End Flight

1. Land the aircraft and disarm (lock) it.
2. First, power off the aircraft by unplugging the battery, then turn off the radio.
3. Finally, remove the battery from the aircraft.
