The advantage that brushless motors have over brushed motors is that they do not have friction since there are no brushes. Without brushes, the motors are more efficient and have a longer lifespan as there is no wear and tear (the brushes in brushed motors wear out with use). They produce less noise, maintain their torque consistently at all speeds, do not overheat, and do not require maintenance.

• Due to the absence of brushes, they exhibit minimal mechanical wear and the need for maintenance is minimized
• They have higher efficiency
• No noise and sparks are caused by friction
• They achieve very high speeds

The bottom of the drone is equipped with a second camera. The bottom camera can be used for image recognition and for achieving extremely stable optical flow positioning.
