Once you've run a few batteries out with the heli just sitting on the floor getting used to the controls, the biggest problem is overcontrolling when working on hovering. The heli goes left so you add right cyclic and now its going right, kinda swinging back and forth and up and down. You really have to make quick small adjustments before it starts moving. You will see it tilt and you must quickly get it level again before it heads in the direction it's tilting. But, don't overcontrol creating another need for input.
