Most RC clubs have instructors, even if they do not have intro pilots. The intro pilot program is a relatively new thing. It allows a new person to come in for 30 calendar days without being an AMA member. The intro pilot has to maintain a certain amount of paperwork regarding students, and there is a small administrative fee the intro pilot (or the club) has to pay to the AMA each year.

The club I am in has several instructors, but none chose to become intro pilots.

Also, it seems that a lot of us have long drives to the flying field. I drive 45 miles each way (takes about an hour).
