How about 10.4kg/w power efficiency of the motor
 

I have been paying attention to the six-axis UAV for a while, and I have also read many professional players' posts. It is clear that the core of a high-performance six-axis UAV is power.Including motor, propeller, electrical adjustment. The mismatch between the three will lead to accidents with drones, which can be smoothened.
Expensive motors are all very well, but weight, battery life, and so on are constraints
So which aspects are considered to be able to reasonably match a system? Skylle Power System is recommended by many tutorials. The kit is designed with high power-efficiency. Under the weight of 3kg and 3.5kg, it could provide a power-efficiency of 10.4kg/w and 9.5kg/w respectively. Even under full throttle and the weight of 7.4kg, it could still achieve 5.6g/w. Can it work in the air?
