Abstract
A captive flying toy airplane is tethered to a boom pivotally mounted to a turntable for pivoting the boom for altitude adjustment of a toy airplane, the turntable being mounted to a pylon base housing containing drive gears therein. A control housing is provided to position first and second wire control members passing through a tube connected to the housing, one controller of the control housing varying the position of a slide wire rheostat to control the speed of the toy airplane, the second controller pivoting a bell crank through a vertical plane to control the position of an altitude control rod passing through the center of the turntable to effect pivoting of the boom. A sound cone mounted within the pylon has the apex portion engaging a circumferential ratchet surface on one of the drive gears for emitting a simulated motor sound proportional to the speed of rotation of the gear.
