An air pumping station for a pneumatic toy vehicle powered by a re-fillable compressed air bottle or canister includes a stabilizing base having a flat ground engaging horizontal lateral bottom including a horizontal projecting geometry proportioned for placement under the feet of the user. The station also includes a fluid-tight vertical cylindrical housing. The station includes a reciprocating piston having a first end in fluid tight relation to interior walls of the housing and a second end defining hand-grippable pumping handles. The station has an air intake valve for the cylindrical housing. The pumping station includes an element for selectable clamping and unclamping of the toy vehicle to at least a first surface of the cylinder, however offset therefrom by a sufficient distance to avoid the reciprocal movement of the piston and grippable pumping handles. The cylinder includes an air exhaust aperture in fluid communication with the base of the cylinder. An air exhaust conduit is provided having a proximal end in fluid communication with the air exhaust aperture and a distal end including an air inlet valve defining a compressed air input to the air bottle of the toy vehicle. The grippable pumping handle and the stabilizing base exhibit elongate substantially co-parallel lateral horizontal axis which, in combination, define a virtual plane which avoids intersection of the toy secured to the cylindrical housing though the selectable clamping elements.

A main wing positioning and release system particularly adapted for use with a toy or model aircraft, includes a wing positioning bracket upon the axial centerline of the aircraft, the bracket having projecting elements directed upwardly from the centerline of the aircraft. The system also includes a wing release mechanism including a lower portion press-fittably securable to the upwardly projecting elements of the positioning bracket to provide proper positioning of the release mechanism relative to the aircraft fuselage, a rear area of the lower portion including a press fittable receiving recess, an upper surface of the lower portion of the release mechanism proportioned for complemental engagement of a lower surface of the main wing. The wing release mechanism also includes an upper portion having upper and lower surfaces, the lower surface proportioned for complemental engagement of the top of the aircraft main wing, the upper portion including a press-fittable connection element complemental to the press-fittable receiving recess in which the recess and element are releasible from each other. A flexible normally openly biased hinge joins respective front edges of such lower and upper portions of the release mechanism from each other. Upon impact of the aircraft, as in a crash or emergency landing mode, the press fittable element and recess will separate from each other, releasing the main wing from the release mechanism without damage to the wing.

A fluid engine for use in pneumatically operated toys such as wheeled vehicles or airplanes includes an engine having a fluid input cavity which is in continuous fluid communication with a source of compressed air, a fluid delivery cavity which is in continuous communication with a piston cavity bounded by a moveable piston mounted in a cylinder member and which is separated from the fluid input cavity by a wall having a valve opening, and exhaust apertures which are separated from the fluid delivery cavity. A valve rod is movably housed to open the valve opening and close the exhaust apertures during the piston's power stroke, and to close the valve opening and open the exhaust opening during the piston's exhaust stroke. The valve rod is operatively connected to a piston to act in synchronism with it by the use of a cam integrally secured to a propeller power shaft.
