Abstract
Abstract A toy aircraft system with an aircraft powered by an electrically driven propeller and motor mounted in the aircraft which, in turn, is mounted on a boom which can rotate about a central point and move up and down in response to changes of the vertical position of the aircraft. The motor receives its electrical energy through the boom which consists of two side-by-side slim wires or rods, one of which is rotatable about its axis to tilt the aircraft forward and backward to guide the direction of flight of the aircraft.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
172 words
A toy aircraft system comprising: a tower defining a system axis and including a source of electrical power; a flight boom having a remote end and a near end; pivot means for mounting said flight boom at said near end to said tower for rotation about said system axis for pivotal movement about an elevational axis, said flight boom including an aircraft control arm and an inactive arm; an aircraft mounted on said remote end of said control arm and said inactive arm and adapted for flight about said system axis, including a propeller for moving said aircraft and an electric motor mounted within said aircraft and connected to drive said propeller; said control arm and said inactive arm together supporting the weight of said aircraft and being electrically conductive to supply electricity from said tower to said aircraft; means for electrically connecting said control arm and said inactive arm to said source of electrical power; and means for electrically connecting said control arm and said inactive arm to said electric motor.
Claim 2
Dependent Claim
172 words
A toy aircraft system comprising: a tower defining a system axis and including a source of electrical power; a flight boom having a remote end and a near end; pivot means for mounting said flight boom at said near end to said tower for rotation about said system axis for pivotal movement about an elevational axis, said flight boom including an aircraft control arm and an inactive arm; an aircraft mounted on said remote end of said control arm and said inactive arm and adapted for flight about said system axis, including a propeller for moving said aircraft and an electric motor mounted within said aircraft and connected to drive said propeller; said control arm and said inactive arm together supporting the weight of said aircraft and being electrically conductive to supply electricity from said tower to said aircraft; means for electrically connecting said control arm and said inactive arm to said source of electrical power; and means for electrically connecting said control arm and said inactive arm to said electric motor.
Claim 3
Dependent Claim
25 words
The toy aircraft system of claim 1 wherein said pivot means includes axle means defining said elevational axis and shaft means defining said system axis.
Claim 4
Dependent Claim
80 words
The toy aircraft system of claim 1 wherein said aircraft has a front, a rear, an aircraft axis extending therebetween, and a center of gravity and wherein said aircraft is pivotally connected to said remote end of said flight boom for movement about a pivot axis parallel to said aircraft axis with said center of gravity being located below said pivot axis such that said aircraft depends pendulously from said boom and is free to bank about said pivot axis.
Claim 5
Dependent Claim
34 words
The aircraft system of claim 3 wherein said control arm and said inactive arm are bent at right angles at said remote end of said boom and are received in apertures in said aircraft.
Claim 6
Dependent Claim
33 words
The aircraft system of claim 1 further comprising a counterweight attached to said flight boom at said near end and extending in a direction opposite to said remote end of said flight boom.
Claim 7
Dependent Claim
33 words
The aircraft system of claim 5 wherein said counterweight is adapted to be moved along said flight boom whereby said counterweight may be located at a plurality of positions relative to said tower.
Claim 8
Dependent Claim
83 words
The aircraft system of claim 1 wherein said control arm is adapted to be rotated about its own axis and further comprising means in said aircraft responsive to rotation of said control arm about its own axis for tilting said aircraft, and further comprising actuator means mounted on said tower and coupled to said control arm to rotate said control arm about its own axis, whereby said aircraft may be tilted to vary the orientation of said propeller and the direction of flight.
Claim 9
Dependent Claim
23 words
The aircraft system of claim 1 wherein said control arm and said inactive arm are arranged side by side in a horizontal direction.
