For most people my age (born in 1958), the first experience with a 'real' flying model helicopter was this ElectroMic "Copter" by Stanzel. I finally acquired one via eBay for a fair price. The "Copter" uses two D-cell batteries in the plastic handle to power a motor, also in the handle, which in turn drives the center wire of a coaxial cable that connects to the helicopter rotor. Flying the Copter is a matter of pressing the power button and then manipulating the handle to direct the model in flight.
