Superflite currently manufactures three different types of fabric. Only two are available for resale at this time. The medium weight, or 102 fabric, is the 2.7 ounce fabric used on certificated and light sport aircraft. It is FAA-approved. The light weight, or 104 fabric, is the 1.7 ounce fabric used on ultralights and some experimental aircraft. Both are sold by the yard.
