Patent ID: 8133089

Claim:
A toy aircraft, comprising: an airframe; and a self-contained modular power system configured to be optionally used with the airframe to propel the toy aircraft and to be optionally used separated from the airframe, comprising: a propulsion unit operable to propel the toy aircraft, the propulsion unit including a mounting foot; a power unit configured to provide power to the propulsion unit to propel the toy aircraft, and remains electrically connected to the propulsion unit while the self-contained modular power system is being separated from the airframe; and a flexible connection that links the propulsion unit to the power unit and is configured to permit relative movement between the propulsion unit and the power unit; the airframe comprising: a wing; a propulsion unit mount configured to removably retain the propulsion unit, the propulsion unit mount including a mount aperture, wherein the mounting foot may be removably inserted into the mount aperture and rotated to engage the propulsion unit with the propulsion unit mount; and a power unit mount spaced from the propulsion unit mount and configured to removably retain the power unit independently of the propulsion unit mount removably retaining the propulsion unit.
