Aircraft
This section introduces functions and features of the B7.
Flight Modes
The following flight modes are available in Bugs 7. GPS mode:
- 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 situations, please refer to the 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.
Optical flow positioning mode:
- If the aircraft does not receive GPS signal or GPS is 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 the GPS is turned off, what’s more, if its altitude is beyond 3 meters, it will enter into the altitude-holding mode, and cannot realize accurate hovering. In this situation, the user should have some basic operations, and be recommended not to fly the aircraft.

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
---|---|---
Home Point| | 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.
- **** During the return home flight, the aircraft will fly straight to the 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 the 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 is lost for more than 6 seconds, the aircraft can not Return-to-Home but descend slowly until lands on 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 the
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.
- If the rear indicator light flashes slowly, the battery icon in the transmitter LCD screen is “ “, and with the transmitter has a “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 within 100 meters distance, the user can cancel the return via the “ ” button.
- When the aircraft’s rear lights flash slowly, the 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’s 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 returned home with the Low Battery RTH function activated, you can not cancel the RTH procedure by pressing the RTH button to regain control of the aircraft.
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 is continuously interrupted for longer than 6 seconds and the APP
control turns 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 cancels it by the transmitter’s return home button
and get back the aircraft’s control right.
Vision System
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 accurate positioning and safe
flight.
Vision Positioning System
function
The Vision Positioning System is typically used in the indoor environment when
GPS is weak or unavailable. It works best when the aircraft’s altitude is less
than 3 meters.
**** The measuring precision
of the 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 altitude-holding mode automatically. Please be
cautious in as following situations:
- Fly fast at an altitude below 0.5m.
- Fly over monochrome surfaces (like pure black, pure red, pure red, and pure green).
- Fly over strong light reflective surfaces or surfaces prone to reflection.
- Fly over water or transparent object surfaces.
- Fly over moving object surfaces (such as crowds, swaying juggles, and glass).
- Fly over an area where light changes dramatically and rapidly.
- Fly over surfaces extremely dark (lux<10) or extremely bright (lux>10,000).
- Fly over surfaces without clear textures.
- Fly over surfaces with highly repeating textures (small grid brick in the same color).
- Fly over surfaces that are tilting over 30 degrees.
- 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.
Aircraft Power Switch
Short-press the aircraft’s power button, and it will turn on, at the same time, the aircraft will have a power-on sound, and the indicator light stays on. Long-press the power button for 3 seconds and the aircraft will turn off and the indicator light will turn off too.
