Over the years some Cox model engines were sold to other companies for use in their products and sold under the other companies names. Examples of these companies were, Testor Corporation, Sanwa & Kyosho of Japan, Johannes Graupner of Germany, Jerobee Industries trading as JoMac Products, Lite Machine Corporation, Kenbrite Corp. Australia and Tissan Haifa in Israel. Of all of the above-mentioned companies, only Tissan Haifa assembled their own engines called the Banana.049. All the rest used motors manufactured by Cox themselves.
