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. |
