A flying toy spacecraft having one or more low pressure channels acting as the primary lift mechanism. Each of the low pressure channels has a bottom member, two sidewalls, and an optional top member. The interior of the channel can be fitted with an airfoil or a trailing reflexed edge. In embodiments having two or more low pressure channels, the channels are spaced apart, thereby forming an inverted channel that stabilizes the flying toy spacecraft against undesired yawing motions.
