     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 5 thereof, a new and improved toy air vehicle embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the toy air vehicle apparatus 10 essentially comprises a &#34;T&#34; shaped body housing 11 formed with a centrally located pivotal hatch 12 and a forwardly oriented motor 13. The motor 13 may be of conventional electrical or gasoline powered type well known in the art and well within the purview of the instant invention. The motor 13 is formed with a first drive shaft 14 forwardly extending from the motor and positioned through a first cylindrical housing 15 and driving first impeller 17 through a first forward gear housing 16 utilizing orthogonally oriented bevel gears. The first impeller 17 is formed with a first shroud 18 therearound integrally formed to the first cylindrical housing 15 to direct a velocity of air therethrough and create a desired venture effect with the inwardly directed lower circumference of the shroud 18 accepting air upwardly from the outwardly turned upper perimeter of the shroud 18, as illustrated in FIG. 2 for example. 
     A second drive shaft 19 extends rearwardly of the motor 13 and is formed to a universal joint 20 that directs power through a third drive shaft 21 and into a gear housing 22, as illustrated in FIG. 4. Within gear housing 22 is a first bevel gear 23 integrally secured to the third drive shaft 21 and directs rotational force orthogonally to the third drive shaft 21 by a respective second and third bevel gear formation 24 and 25 that are respectively secured to a fourth and fifth drive shaft 26 and 27. 
     The fourth drive shaft 26 directs power to a second impeller 28 and the fifth drive shaft 27 directs power to a third impeller 29 that are formed with respective second and third shrouds 30 and 31 of construction equal to that as illustrated in FIG. 2 of the first shroud 28. A third and fourth gear housing 32 and 33 are formed to the third and second impellers respectively and utilize bevel gears, as illustrated in FIG. 5 for example, to direct power to the respective impellers. A second cylindrical housing 34 and a third cylindrical housing 35 are secured integrally to the gear housing 22 and encompass the fourth and fifth drive shafts respectively, as illustrated in FIG. 4. Reference to FIG. 5 illustrates the means by which the second and third impellers are rotated for directional orientation of the vehicle during an airborne traverse wherein a second cylindrical housing extension 34a and a third cylindrical housing extension 35a are secured to the respective second and third cylindrical housings 34 and 35 by a joint formation, as illustrated in FIG. 5. As illustrated, a first rotational joint 36 secures the respective second cylindrical housing 34 and a second cylindrical housing extension 34a together wherein similarly a second rotational joint 37 effects a similar operation with respect to the third impeller 29. A first flange member 38 is integrally formed to the second cylindrical housing 34 and a second flange member 39 is integrally formed to the second cylindrical housing extension 34a wherein a series of through extending apertures extend through the respective flange members 38 and 39 with threaded fasteners 40 removably positioned through the through extending apertures that may be removable to rotate the respective cylindrical housings as desired. It may be understood that various other connections may be utilized, such as frictional joints that may be manipulated and rotated by various mechanical drives, such as drive belts and the like, but for purposes of illustration and effectiveness, the respective rotational joints 36 and 37 are adequate for the toy air vehicle 10 in use. Underlying the body housing 11 is a forward skid 42 and a plurality of rear skids comprising a first and second rear skid respectfully 43 and 44 that accept snap-on pontoons 45, as illustrated in FIG. 3, within longitudinal grooves 46 of the pontoons 45. 
     When the pontoons 45 are secured to the skids 42, 43, and 44, the respective second and third impellers 28 and 29 are rotated in the direction of rotation of an arrow 41, as illustrated in FIG. 3, to align the impellers 28 and 29 with the longitudinal axis of the body housing 11 and thereby the toy air vehicle 10 may be utilized as a pontoon boat for water traverse. 
     As to the manner of usage and operation, therefore, of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relative to the manner of usage and operation will be provided.
