A three-field model to study drift-resistive, low-frequency waves in low-{beta}, nonaxisymmetric plasmas [J. L. V. Lewandowski, Phys. Plasmas {bold 4}, 4023 (1997)] is used to analyze the effect of the inhomogeneities in the stellarator magnetic field on the fastest (linear) growth rate, {gamma}. Extensive numerical calculations for a toroidal heliac show that not all Fourier components in the representation of the equilibrium configuration are important as far as {gamma} is concerned. {copyright} {ital 1999 American Institute of Physics.}
