We propose to make continuum and recombination line observations of the radio stars MWC349 and Eta Carinae which show STRONG HYDROGEN RECOMBINATION LINE MASER emission at millimeter and submillimetre wavelengths. The proposed observations will provide the kinematics and the physical properties (density and temperature structure) as a function of radius for these ionized stellar winds and will tell us to what extent maser emission also affects hydrogen recombination lines with smaller quantum numbers. From the full characterization of the ionized stellar winds in these sources we will be able to obtain confident mass loss rates, and put strong constrains on the driving mechanisms for the mass loss in these sources. In particular, for MWC349, the data will essential to establish the role of the neutral disk in the mass loss processes, to derive its kinematics, and to establish the nature of the central star (young or evolved).
