Abstract: Toy aircraft, modular toy aircraft, capacitor-based modular power systems, and toy aircraft kits are disclosed. Toy aircraft may include a self-contained power system and an airframe. The self-contained power system may include at least one propulsion unit operable to propel the toy aircraft and a power unit. The power unit may include a capacitor that is electrically connected to the at least one propulsion unit. The capacitor may be configured to provide power to the at least one propulsion unit to propel the toy aircraft. The airframe may include a wing, a first mount configured to removably retain the at least one propulsion unit, and a second mount configured to removably retain the power unit.

Abstract: A toy helicopter has a fuselage having a front end a rear end and two lateral sides. A main motor is supported from the fuselage. A main rotor is operably connected to the motor and has at least one rotor blade that rotates about a center axis generally laterally centered with respect to the fuselage. The at least one rotor blade is configured and positioned to provide lift and has a rotational path having a maximum radius. A bumper is fixedly connected to the fuselage, is spaced entirely axially downwardly from the at least one rotor blade and extends radially outwardly from and at least partially around the fuselage. At least a portion of the bumper has a maximum radial dimension from the center axis at least as great as the maximum radius of the rotational path of the at least one rotor blade.

Abstract: Toy aircraft may include an airframe, a modular power system, first and second wheel supports, and first and second wheels. The modular power system may be configured for selective use with and selective removal from the airframe. The power system may include a propulsion unit operable to propel the toy aircraft and a power unit, which may include an energy source configured to supply energy to the propulsion unit. The airframe may include a fuselage, a propulsion unit mount, which may be disposed on the airframe and configured to removably retain the propulsion unit, and a power unit mount, which may be disposed on the fuselage and configured to removably retain the power unit. The first and second wheel supports may extend from the power unit mount toward respective first and second wheel mounts to which the first and second wheels may be rotatably mounted.

Abstract: A toy vehicle includes a plurality of wheels and an electric motor operably coupled to rotate at least one of the wheels. At least the one wheel and preferably each rotated wheel includes a hub and a tire mounted on the hub. The tire has an interior sufficiently hollow to make the wheel buoyant in water and the wheel is sufficiently sealed to prevent water penetration of the interior of the tire with the wheel immersed in water. The tire has a central portion surrounding the hub and a plurality of hollow lobes spaced from one another about the central portion. Each lobe has a pair of opposing outer sides at least one outer side being at least partially inwardly cupped to improve thrust caused by rotation of the wheel in water.

Abstract: Toy aircraft, modular toy aircraft, modular power systems, and toy aircraft kits are disclosed. Toy aircraft may include a self-contained power and control system and an airframe. The self-contained power and control system may include at least one propulsion unit operable to propel the toy aircraft and a power and control unit. The power and control unit may include at least one energy source, be electrically connected to the at least one propulsion unit, and be configured to control operation of the at least one propulsion unit to control flight of the toy aircraft. The airframe may include a wing, a first mount configured to removably retain the at least one propulsion unit, and a second mount configured to removably retain the power and control unit.

Abstract: A carrying clip for detachably connecting an accessory to a tool belt in the form of an elongate flexible strap defining an upper edge includes a gripping portion configured to be gripped by the fingers of a user and positioned in proximity, and positioned in proximity to the straps upper edge. The gripping portion is associated with and supports an accessory to be detachably connected to the strap. An attachment member, which may be in the form of a spring-clip or a snap-lock clip arrangement, is used for detachably connecting the gripping portion to the strap and for removing the gripping portion and associated accessory by engagement of the gripping portion with the finger of the user and lifting the gripping portion in a general upward direction relative to the strap.
