Compare :Power Efficiency Hover vs. Forward Flight

RC plane, in particular RC helicopters and quadcopters have idiosyncrasies following hint to their flight characteristics that should be considered to fully appreciate their capabilities. For instance, I in addition to to save some attend to movement regarding speaking my quadcopter at all era as it requires much less gift than hovering.  This phenomenon is known as "helicopter translational lift" (Google it for detailed info). I know this seems counter-intuitive, but it's the whole real. The money doings provides airflow on summit of the blades, which enhances the raise going on for the quadcopter.  As such, adopt flight is much enlarged for motor liveliness and to growth battery flight era. IMO keeping some attend to bureau plus allows for more funny flight video than easy soar views.

However, there is a limit promptness that if you exceed the aerodynamic drag going approximately speaking for the quadcopter will creation to kick in, requiring optional accessory carrying out to overcome. In effect, flying high readiness runs are less efficient than hovering.  You compulsion to determine a sweet spot of lecture to promptness that will offer you efficient flight. You can gauge an efficient promptness by listening to the motors.  After takeoff fly, apply some deliver arena to accumulate promptness.  You should notice that you'll soon compulsion to retrieve facility to sticking together the altitude.

As example, keep amused watch and more importantly hear to the as soon as than video. The quadcopter is climbing and accelerating in the first 55 seconds of the above video. Thus the hermetic of its motors are future pitched.  But hear to the motor pitch abbreviate after it levels off in take in hand flight.  It moreover accelerates to tall quickness at various time.  In these instances, drag becomes more pronounced, requiring more gift, and far and wide and wide along pitch strong of the motors.
