Abstract: The present invention includes an apparatus for guiding movement of an object along a track. The apparatus includes an attachment member defining an opening. A bushing is positioned in the opening and the bushing is laterally moveable within the opening. A plunger is attached to the bushing and the plunger is configured to move towards and away from the bushing. A guide mechanism is pivotably attached to the plunger and the guide mechanism is moveable along the track. According to other aspects of the invention, a slider is used in combination with a roller as the guide mechanism.

Abstract: An amphibious airplane having an engine assembly mounted at a top center location in the fuselage, and a tail assembly having a horizontal fin in an elevated position so as to be in the propeller air stream. A lift augmenting aerodynamic surface is positioned at the top middle portion of the aircraft fuselage, with the propeller being at the concavely curved rear end of the lift augmenting surface. A pair of platforms are positioned on opposite sides of the fuselage at lower locations adjacent to a passenger section of the aircraft. These platforms are aerodynamically aligned and also have strakes extending forwardly therefrom along opposite sides of the fuselage. In cruise mode, the increased velocity imparted to the propeller air stream acts on the horizontal fin to exert a downward force, with the various forces of the airplane balancing each other.
