Pjtg0707,

Pilot, verb, to direct or steer. Pilot, noun, one who pilots.

What term would you suggest for someone who moves a stick around and makes the plane go where wanted? Most of us think we fly the RC plane and understand it is a not a 747 or even a piper cub. The term pilot seems appropriate and does not imply we think we are licensed or even capable of flying a full scale aircraft.
If someone were to write he was teaching an F15 fighter pilot to fly RC I would find it interesting and perhaps humorous. If an RC pilot were to claim he could fly an F15 as a result of his RC experience I would find it hysterical.
