ABSTRACT:
This invention provides improvements to flying toy models of hot-air balloons which use helium instead of hot air for lift.
An object in the shape of an inverted receptacle is inserted into the mouth of the lifting envelope and serves to accurately replicate the shape of the neck and the open mouth of a full-sized hot-air balloon lifting envelope. A novel method of assembly incorporates the inverted receptacle into the lifting envelope and provides for the efficient attachment and detachment of the gondola to the lifting envelope.
