If you are not careful, tiny grains of sand can temporarily disable the motors, or worse

So finally, for fear that it would eventually break the line, I used the fail safe command to kill the motors and watched as that investment fell to the ground .. broken

I am wondering if that motor is the problem or the props I received?

I had remote issues, motor overload issues, connectivity issues, interference issues and crashed my drone a few weeks ago

I am not sure if this can damage the motors.

The 12 month warranty covers any hardware issues that the drone might have (i.e. stress cracks, motor problems, camera/gimbal problems, etc.).Cons:-Range

The third flight, the quad began acting a little erractic, then suddenly the motors reveled into a really high pitch by themselves and the quad tried to fly away

That means it WON"T FLY

,it's an excellent beginner drone ,captures great footage ,reaches great altitudes and impresses the sh*t out of everyone who sees it
