    Accelerometers are not a good choice to maintain pitch, yaw or roll in an aircraft. Gyros need to be used for this. An accelerometer provides half of what you need.
    The main issue is that the accelerometer measures the acceleration in xyz relative to the board, not the ground. You could very easily have the helicopter pitched up or down and still maintain 1g in the z relative to the board. If your helicopter is pitched over and maintains 1g in the z, contact with the ground will happen eventually.
