An observational program for study dynamics of planetary nebulae with the help of RRL is discussed. The expansion velocities may be found from observations of radio recombination lines in different wavelength. The method is free of the microturbulence problem inherent in standard spectroscopic methods. Set of theoretical models was computed for NGC 7027. Observations of RRL with n > 150 may allow making choice between models with high and low microturbulence.
