    • 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.
    • 玩具直升机具有前端具有后端和两个侧面的机身。 主机由机身支撑。 主转子可操作地连接到电动机,并且具有至少一个转子叶片,所述转子叶片围绕中心轴线大体上相对于机身横向居中地旋转。 至少一个转子叶片被构造和定位成提供升力并且具有最大半径的旋转路径。 保险杠固定地连接到机身,与所述至少一个转子叶片完全轴向向下隔开并且从机身的径向向外并且至少部分地围绕机身延伸。 保险杠的至少一部分具有距中心轴线的最大径向尺寸,至少与至少一个转子叶片的旋转路径的最大半径一样大。

    • 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.
