    en.wikipedia.org/wiki/Radio-controlled_aircraft

    A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is radio controlled by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on ...

    (Age requirements for gliders and balloons are slightly lower.) This includes 100 hours in powered aircraft, 50 hours in airplanes, and 100 hours as pilot in command (of which 50 hours must be cross-country flight time). In addition, commercial pilots must hold an instrument rating, or otherwise they would be restricted to flying for hire only ...

    Prior to carrying passengers for the purpose of conducting aerobatics, pilots must first learn to fly aerobatic maneuvers. Pilots in Canada may learn aerobatics in one of two ways: pilots may spend 20 hours of flight time learning aerobatics on their own or pilots may fly 10 hours with a licensed Class 1 or Class 2 Aerobatic Instructor.
