Abstract: An apparatus and method of retrieving a radio-controlled fuel-powered model boat is disclosed. The apparatus includes a pivot arm, with a pinion gear and an idler gear, that is attached to the shaft of a secondary motor. The idler gear in said pivot arm engages a driven gear that turns the model boat's propeller shaft by transferring the secondary motor shaft's rotation through gears to the propeller shaft. The apparatus includes a movement limiting bracket that limits the pivot arm's movement to either engage or disengage the driven gear attached to the model boat's propeller drive shaft.

Abstract: This invention provides and improved apparatus and an improved method of adjusting the tractive torque at the driven wheels of a scale model vehicle employing an enclosed friction driven differential. The invention's improvements allow this adjustment to be accomplished without disassembly of the driven axles, or removing any member of the differential's enclosure to gain access to the internal adjusting components.

Abstract: A method and apparatus for counting the laps completed by a remote-controlled model that detects a spurious radio-frequency electromagnetic signal spontaneously generated by the unmodified model. Presently, each model must carry on-board lap-counting signal generating apparatus. This invention eliminates the need for such apparatus, and reduces the complexity, weight, and cost of such models.

Abstract: A combination universal hobby cabinet system, including a workbench, wherein the cooperative combination includes an organized storage cabinet having one member that is completely removable from the cabinet and then becomes a workbench which may be set on top of the closed cabinet or other flat surface to become a work station, and wherein the interior of the cabinet uniquely provides stowage space for materials and tools and for the workbench, all for use in the practice of particular hobbies, one embodiment of which system encompasses the hobby of fly-tying to create fishing lures.
