Aircraft
This section introduces functions and
features of the Bugs 12EIS.
The following flight modes are available in Bugs 12EIS.
● When the aircraft is in GPS mode, it can receive the GPS signal to realize accurate hovering.
● If the GPS signal is weak, the aircraft will enter into altitude-hold or optical flow position mode.
(For specific situation, please refer to APP status bar)
● Please make the aircraft land ASAP when the GPS signal is poor lest any accidents.
● By the way, please note do not fly the aircraft in any weak GPS signal place or narrow space
place lest any flight accidents.
GPS mode:
● If the aircraft does not receive GPS signal or GPS turned off and its altitude is within 3 meters,
it automatically enters into the optical flow positioning mode. It utilizes the optical flow positioning
mode to hover stably.
● If the aircraft does not receive GPS signal or GPS turned off, what's more its altitude is beyond 3
meters, it will enter into altitude-holding mode, cannot realize accurate hovering. In the situation,
the user should be have some basic operations, recommended not to fly the aircraft.

!● During the return home flight, the aircraft will fly straight to return home point and cannot
avoid obstacles. Please make sure there are no any obstacles on the path.
● 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.
Aircraft status indicator
When the GPS signal is available (more than 7 satellites is presented), use the RTH button on the
remote controller (Pic. 1) or tap the RTH button in the “M RC PRO” APP (Pic. 2) and then 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 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. If the rear indicator light flash slow, the battery icon in transmitter LCD screen is “ ”, with transmitter
has “DIDI” sound. As only the aircraft is beyond 30 meters altitude or 100 meters distance, the aircraft
will return home automatically. As long as the aircraft is in 100 meters distance, the user can cancel
the return via “ ” button.
2. When the aircraft rear lights flash slowly, battery icon “ ” is shown on the remote controller or on
the “M RC PRO” 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.

Home Point
GPS Description
If a strong GPS signal (satellites over 7) was acquired before takeoff,
the 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.
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.
Return to Home (RTH)

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.
!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.
The optical flow system consists of optical flow lens modules. The optical flow system is an image
positioning system, obtaining the aircraft’s position through the optical image thereby ensuring the
the accurate positioning and safe flight.
Vision System
Out of connection return home function
The GPS signal is good (the No. of GPS satellites is more than 7), the compass is working and the
home point has been recorded successfully, if the control signal continuously interrupted for longer
than 6 seconds and APP control turning off, the flight control system will take over the transmitter
control, controlling the aircraft to fly return home point. If the control signal is restored during returning
home, the returning home flight will continue unless the user cancel it by transmitter’s return home
button and get back the aircraft’s control right.

!The measuring precision of optical flow system will be affected easily by the light strength
and the features of object surface texture. Once the optical flow is unavailable, the aircraft
will enter to altitude-holding mode automatically. Please be cautious in as following situations:
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 surfaces without clear textures.
9. Fly over surfaces with highly repeating textures (small grid brick in the same color).
10. Fly over surfaces that are tilting over 30 degrees.
11. 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.
● If the light is dim, please turn on the optical flow supplement light.
