Aircraft

This section introduces functions and
features of the B4W.

Flight Modes

Your B4W has 3 flights modes:

GPS mode: ON

Slide the button up at the right side to position “ON” (Pic.1), the aircraft is in GPS mode and can

precisely position and hover by the assistance of the GPS module. Warm tips: When the GPS signal

is weak, the aircraft will automatically enter into Gesture mode( flying altitude ≥ 3 meters) or vision

positioning mode(flying altitude＜ 3 meters).

Gesture mode: OFF

Slide the button down to “OFF” (Pic.2), the aircraft is in Gesture mode that GPS is not used for
positioning, and the aircraft only uses the barometer to maintain altitude. The aircraft will not fly with

precise positioning and hovering. Gesture mode requests pilot with good skill.

In Gesture Mode, the aircraft cannot position itself or brake automatically, which increases the risk
of potential flight hazards. The aircraft will be also more easily affected by its surroundings.
Environmental factors such as wind can result in horizontal shifting, which may present hazards,

especially when flying in confined spaces.

Vision positioning mode:

Once the GPS signal is weak or unavailable and the flying altitude is less than 3 meters, the aircraft
will automatically enter into vision positioning mode. Assisted by the vision system, the aircraft could

perform precise positioning.

Return to Home (RTH)

The Return-to-Home(RTH) function brings the aircraft back to the last recorded Home Point. There

are 3 types of RTH: smart RTH, low battery RTH and failsafe RTH. This section describes these 3

scenarios in detail.

GPS Description

If a strong GPS signal (satellites over 7) was acquired before takeoff, the

Home Point

initiated.

● Aircraft can not return to the Home Point when the GPS signal is weak or

unavailable.

● Aircraft will stop ascending and immediately return to the Home Point if user

moves the throttle stick in the aircraft reaches 15 meters altitudes or beyond
during Smart RTH.

● If there is no GPS signal and the remote controller signal lost for more than
6 seconds, the aircraft can not Return-to-Home but descend slowly until land

to the ground and lock the aircraft.

Home Point is the location from which the aircraft launched. The GPS signal
strength is indicated by the GPS icon( ). The aircraft rear indicator lights
will blink rapidly from yellow color to green color when the home point is
recorded.

Bugs 4W User Manual

Smart RTH

When the GPS signal is available( more than 7 satellites is presented), use the RTH button on the

remote controller or tap the RTH button in the “Bugs Go” APP and follow the on-screen instructions to

initiate Smart RTH. During the smart RTH, you can use the remote controller to guide the aircraft

around obstacles. You can press the RTH button again to exit RTH procedure and regain control of
the aircraft.

Low Battery RTH

The low battery level failsafe is triggered when the MJX intelligent battery is depleted to a point
that may affect the safe return of the aircraft. Users are advised to return home or land the aircraft
immediately when prompted.

1. When the aircraft rear lights flash slowly, battery icon “ ” is shown on the remote controller or

on the “Bugs Go” APP. And steady “beep beep beep... beep beep beep” sound is heard. At this

moment, the aircraft will automatically return to the Home Point if the flying altitude is beyond 50

meters or the flying distance against the home point is beyond 100 meters.

2. When the aircraft rear lights flash slowly, battery icon “ ” is shown on the remote controller or on
the “Bugs Go” APP. And steady “beep..beep...beep” sound is heard. At this moment, the aircraft will

automatically return to the Home Point if the flying altitude is beyond 15 meters or the flying distance
against the home point is beyond 15 meters. If the aircraft flying altitude is less than 15 meters or

the flying distance is less than 15 meters, the aircraft will automatically land to the ground.

Attention: When the aircraft is automatically return home with Low Battery RTH

!

function activated, you can not cancel the RTH procedure by pressing the

RTH button to regain control of the aircraft.

Failsafe RTH

If the Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH

will be automatically activated if the remote controller signal is lost beyond 6 seconds. Return-to-Home

can be cancelled by the pilot, allowing them to regain control when the remote controller signal

connection is re-established.

Vision System

Consisted by camera ① and ultrasonic sensor ②, the Vision System locates at front bottom of your
B4W. It is a positioning system that is composed by image sensor and ultrasonic sensor. Your B4W
acquires its location through using the camera sensor to detect the ground texture and visible features.

Meanwhile, assisted by the ultrasonic sensor, your B4W could determine the altitude where it stays,

which could better insure the fly safety and gain precise positioning.

①

②

Vision Positioning System function

The Vision Positioning System is typically used in indoor environment when GPS is weak or
unavailable. It works best when the aircraft altitude is less than 3 meters.

3m

-9-

Bugs 4W User Manual

The precision of the vision system is easily affected by the light strength and features

!

of the surface textures. It would happen that the ultrasonic sensor could work normally
to detect the altitude when it is flying over objects that is made by sound-absorbing

materials. Once the image sensor and ultrasonic sensor are both not available, your

aircraft will switch to Gesture mode automatically. Be cautious to operate the aircraft
in the following situation:

1. Fly fast at an altitude below 0.5m.

2. Fly over monochrome surfaces (like pure black, pure red, pure red and pure green).

3. Fly over strong light reflective surfaces or surfaces prone to reflection.

4. Fly over water or transparent object surfaces.

5. Fly over moving object surfaces (such as crowds, swaying juggles and glass).

6. Fly over an area where light changes dramatically and rapidly.

7. Fly over surfaces extremely dark (lux<10) or extremely bright (lux>10,000).

8. Fly over material surfaces that is good at absorbing ultrasonic waves (like thick
carpet).

9. Fly over surfaces without clear textures.

10. Fly over surfaces with highly repeating textures (small grid brick in the same color).

11. Fly over surfaces that are tilting over 30 degrees (could not receive the echo of the
ultrasonic wave).

12. Flying speed should be controlled not to be too fast. When the aircraft is 1 meter

against the ground, the flying speed should not be over 5m/s; When the aircraft is
2 meter against the ground, the flying speed should not be over 14m/s.

● Keep sensors clean at all times.

● The vision system is only effective when the aircraft is within the altitude range of

3 meters.

● Make sure that the light is bright enough and the surfaces is with clear textures so
that the vision system can acquire the movement information through recognizing

the ground textures.

● The vision system may not function properly when the aircraft is flying over water,

low light ground and surfaces without clear patterns or textures.

● Do not use other ultrasonic device with a frequency of 40KHz when the vision

system is in operation.

Attention: Keep animals away from the aircraft when the vision system is activated.

!

The ultrasonic sensor emits high frequency sounds that are audible to
some animals.

● Signal connection is done once for all if the remote controller is not linked to other

!

aircraft.

● Set the connection one by one to avoid signal connection error.

Aircraft initialization detection

After signal connection, the aircraft enters into initialization detection procedure with front and rear
lights flashing red, green and yellow alternatively. Make sure that the aircraft is set on a flat and still
surface for the initialization detection. The aircraft initialization detection takes about 8 seconds. Once

the remote controller sends out “Di Di” sounds and the aircraft front and rear lights flash yellow

alternatively, initialization detection is completed.

detection.

Aircraft compass calibration

1. Compass calibration should be performed after successful aircraft initialization detection.

2. Aircraft compass calibration should be done for every flight. That is to say, if changing new battery
or the battery is reinstalled, compass calibration should be done again.

Two steps of compass calibration:

Step 1: Horizontal calibration
After successful aircraft initialization detection, the aircraft front and rear lights flash yellow
alternatively. Hold the aircraft horizontally and rotate it 360 degrees along the central axis for

about 3 circles. The aircraft front and rear light will change from flashing yellow alternatively

to flashing green alternatively when horizontal calibration is completed.

Step 2: Vertical calibration

Hold the aircraft with camera facing up, and rotate it 360 degrees along the central axis for
about 3 circles until the front and rear lights of the aircraft change from flashing to solid on,

the compass calibration is successful.

and make sure that the satellite amount is over 7.

● Please do not calibrate the compass in strong magnetic area, such as magnetic

!

field, parking place or construction areas with underground reinforcement.

● Please do not carry magnetic materials with you (such as keys, cell phones, etc)

when calibrating compass.

● Please keep away from big metal when calibrating compass.

Gyroscope calibration

After the aircraft and the remote controller are banded, set the aircraft on flat ground and follow the

indication photo as below to calibrate the gyro. Once the aircraft front lights turn from flashing to solid

on, it means that the gyro calibration is succeeded.

● The gyroscope calibration has been done by factory default. Gyroscope calibration
