Hi,
There are no helicopter/airship examples that I know of, but it's very easy to do. You need to apply a vertical force (y-axis) on the helicopter body to make it rise and then let gravity allow it to fall again. You can use dBodyAddForce(body,x,y,z)/dBodyAddRelForce(body,x,y,z) to do this, add a positive value to the y parameter. To move the helicopter while it's in the air, apply a force on the x and/or z axis.
