The RF-8-GAZ-98 aerosan was designed to run on four skis, two of which were steered. The hull was semi-enclosed, two-place, with a front-rear positioning of the crews seats. For ease in conducting fire from the machine gun and for enlarging the horizontal firing fan, the gunner sat in the forward seat and the driver in the rear of the cabin. The engine was mounted on a special pylon behind the drivers compartment. The GAZ-98K used the M-11 aviation engine with 110 h.p. in place of the automobile engine, which gave the vehicle more dynamic performance.
