Scale transformation introduced by Connor and Taylor is applied to the model equations for the resistive interchange mode (G mode) and the resistive drift wave in a high shear helical system. The electron pressure gradient term in Ohm's law is essential in deriving the present results. Scaling of collisionless transport along stochastic fields due to the G modes coincides with the result based on the mixing length theory. When the resistive drift waves are dominant, the predicted transport is k sup 2/s sup 2 times the pseudo-classical transport, where k is the characteristic length of density gradient and s is the shear parameter.
