Hi Pinky. I got my PPL(A) a couple of years ago, then went for a trial helicopter lesson just for something different, and got completely hooked, so I know exactly what you mean. I just got my PPL(H)a couple of weeks ago, and have been checking out requirements for the CPL which is in a state of change right now due to JAR. IF I've understood it right, you now have to get a CPL, then do an instructors course. I can't remember the details of numbers of hours involved etc, but I do have the details somewhere and can look it up for you if no-one else gives you an answer.
