Got my F450 flying now just need more pratice.
When I start the motors all run nice and sweet but just at the point of take off (ie just as the machine goes light on the ground)
the whole machine vibrates, as if the props where out of balance, which they are not.
As soon as the copter as left the ground the vibration stops.
Is this normal? or is there some other problem?
lvl.1
