Looking from the front of the drone, we met with two binocular sensors on top (MavicPro is currently the only small drone with binocular obstacle avoidance), while the bottom is an inverted motor.
From the rear, we will see the drone's WiFi information, fuselage indicator, and cooling holes. The rear motor is positioned above, and then the two tripods support the body like high-heeled shoes.
Looking from the side, we can see the overlapping of the two double-axes arms, allowing the drone to have more space to accommodate the longer arm.
The following figure we can see, MavicPro lateral size and iPhone6sPlus almost the size.
Although in terms of size, the folded MavicPro is still inferior to the current self-timer drone, zero-degree DOBBY (above), but the size of the two has not been much difference, still with the other 250-level self-timer Man-machines, such as XEROXplorermini or Yuneec Breeze, are about the same size.
