With more particularity and with reference to FIGS. 1A and 1B the upper body 30 attaches to the lower body 32 by any suitable means, such as by any type of fastening or locking mechanism or friction fit or gluing. The upper body 30 is an arcuate member having a first side 31 and a second side 33. The first side 31 is a convex side defining a top outside portion, and the second side 33 is the concave side functioning as the top inside portion of the present invention. Similar to the upper body 30, the lower body 32 is also an arcuate member having a first side 38 and a second side 40. The first side 38 is the convex side functioning as the bottom outside portion, and the second side 40 is the concave side a bottom inside portion of the housing. The upper body 30 encloses a plurality of members, as described below, and is mounted to the lower body 32 and attaches thereto.

Generally, the servo motor assembly denoted in FIG. 18 attaches to the second side 40 of the lower body 32. The steering block assembly 20 mounts upwardly to the servo motor assembly 18 by way of a steering mount 42. Moreover, the main quadripartite blade 27 extends above the steering block assembly 20 and beyond the lower body region into upper body region. Additionally, the belt adjustor assembly 26 and the servo rear prop assembly 22 are attached to the second side 40 of the lower body 32, the belt adjustor assembly 26 being positioned between the servo motor assembly 18 and the servo rear prop assembly 22.

The servo motor assembly 18 attaches to the second side 40 center of the lower. As is known to those having ordinary skill in the art to which the said subject matter pertains, a servo motor assembly 18 is the motor assembly be it electric, hydraulic, thermal-combustion, or any other type of motor, that serves as the final control element in an automatic feedback control system for mechanical motion, and receives power from an amplifier element and drives the load with a linear or rotary motion. Further such a motor assembly includes a starter system or assembly 44 which is positioned proximate a motor (here denoted at 48) and includes a starter 44a, a starter gear 44b, and a starter linkage 44c. The starter system 44 may be, but is not limited to, a manual starter assembly, an on board battery starter assembly, or the like, as is known to those skilled in the art.

With more particularity, the servo motor assembly 18 hereof comprises a plurality of main members and is secured in the center portion of the lower body 32, by at least one and, preferably, two or more motor mounts 50. Each mount extends perpendicularly from the bottom plane of the lower body 32, and is positioned such that the right and obtusely angled vertical inclines, preferably angled at about 81.degree. and 90.degree. from the motor mounts 50, face the front and the rear, respectively.

The motor 48 is secured by the motor mounts 50 by way of two "tap thru" holes 52 in each mount 50 that allow attachments to the cylindrical motor 48 which, in turn, connects to an exhaust assembly 54 from the frontal left half portion, curving around the front of the motor 48, then passing past the motor mounts 50. Proximate the rear dorsal portion of the motor 48, the motor 48 connects to a drive gear 58, and likewise to a drive gear side 60. The drive gear 58 has a ruffled inside diameter and is secured to the drive gear side 60 by any suitable means such as threaded fasteners or the like, where an upward attachment is made to a universal swivel 62.

The steering mount 42 is secured in position by the two motor mounts 50, also, where the steering mount 42 provides an attachment to the starter bracket 64, at a first end thereof. The opposite end of the starter bracket 64 connects to and provides support for the rear of the motor assembly 18. As shown, from the vertical attachment to the steering mount 42, the starter bracket 64 declines downwardly at an angle, and, at the base of the motor mounts 50 curves back upwardly obtusely, preferably, at an angle greater than 130 degrees relative to a horizontal axis. Thus, the starter bracket 64 connects obtusely, from the declined angle of origin, to the rear portion of the motor assembly 18.

The steering mount 42 also supports a lower steering bracket 66. The lower steering bracket 66 comprises a plurality of servos 67, four of which are shown. The bracket 66 is connected anteriorly, posteriorly, and bilaterally to a plurality of first or small steering arms 68a, 68b, 68c, and 68d that are, each, respectively linked to a respective second or large steering arm 70a, 70b, 70c, and 70d by a connecting mechanism. The connecting mechanism comprises a bushing 72 connected to an arm pivot pin 74, and a C-clip 76. Each set of steering arms are, respectively, positioned anteriorly, posteriorly, and bilaterally. The lower steering bracket 66 is, also, connected to an upper pulley bracket 78, which supports a plurality of rod locks 80 (two of which are shown). The rod locks 80 respectively, attach to the associated gear pulleys 82 and gear pulley sides 84 to which the drive belt 86 is strapped and which further connects to the belt adjuster assembly 26, and finally to the rear prop assembly 22.

The universal swivel 62 is upwardly connected to the rotating spindle 87, which anteriorly, posteriorly, and laterally attaches to the pivot rods 88 that link to the respective steering swivels 90, joining the nearer end of the four large steering arms 70a, 70b, 70c, 70d, opposite to the respective small steering arms 68a, 68b, 68c, 68d. The universal swivel 62 serves in the steering of the object 10 by way of the steering arms 68a-d and 70a-d.

The pivot rods 88 are pressed into the rotating spindle 87, and a facial thrust bearing (not shown) is pressed into the spindle so that the assembly can rotate to prevent wedging.

The upper steering bracket 91 links the main symmetrical quadripartite blade 27 to the rotating spindle 87.

A belt adjustor assembly 26 such as that shown on FIG. 2, as known to those skilled in the art to which the present invention pertains, is a pulley assembly employed to lessen the counter spinning of the object 10. The drive belt 86 is strapped to the gear pulley 82, the belt adjuster assembly 26, and finally to the rear prop assembly 22.

The belt adjustor assembly 26 comprises a plurality of main members, and is mounted onto the lower body 32. The belt adjuster assembly 26 is positioned posteriorly between the motor assembly and the rear prop assembly 22. Specifically, the adjuster assembly 26 is mounted onto the lower body 32 by way of pivot arm locks 94, at the location where the anterior portion of each pivot arm lock 94 is attached to an adjustor bracket 96 and the posterior portion of each arm lock 94 is attached to the swivel arm 98. The swivel arm 98 in turn, provides support to a pulley rod 100 oppositely rotating pulley discs 99. A means for rotating the rear prop may be any suitable means and is, preferably, cable drives.

The rear prop assembly 22 is mounted to the rear portion of the lower body 32 with a servo side mount box 110 which, in turn, connects to a servo 112. The servo side mount box 110 may be mounted onto the housing by any suitable means. The servo 112 links to the pulley 114 through a pair of connecting rods 116 and 118. Posteriorly interconnected to the pulley 114, the pivot arm 120 serves to apply pressure upon the rear prop assembly 22 to enable aerial control, including lessening counter spinning of the object 10. Moreover, a pitch rod 122 connects to the pulley 114 oppositely from the servo side. The blade arms 124 of the assembly 22 connect to the pulley 114 by way of the pitch rod 122.

As known to those skilled in the art to which the present invention pertains, the control mechanism of the present invention may be any suitable means, but preferably is a nine channel radio-controlled system, including a seventy-two MHz operating system providing a five mile range for controllability. Specifically, the control system preferably comprises the hand-held radio transmitter (not shown) providing the user with the ability to control and maneuver the present invention when it is in flight. Moreover, the control system preferably comprises an on-board radio controlled receiver which receives the signals from the accompanying hand-held transmitter. Although not depicted in the drawings, the control system described above may be of the similar kind to those that are commercially available. Additionally, the position of the on-board radio controlled receiver may be at any efficient or convenient location within the present invention, by any suitably means.

The present invention, thus, provides a new type of device that may be used both as a recreational and surveillance item. Uniquely, this present invention possesses the aerial characteristics that no other similar device of its size possesses. That is, the present invention possesses the ability to continuously revolve throughout the x, y, and z axes. Thus, the present invention fills the void of devices having such aerial characteristics.
