Hi , I'm searching for information on a plane sold in the 70's. I believe it was a cessna. It was a rechargable free flight plane that came with 4 or 5 discs. When these discs were inserted in the plane the plane would fly a different pattern depending on which disc was inserted. I recall the cox Adam 12 gas powered car had similar discs when it first came out before they switched to the steerable version. Any Information would be greatly Appreciated. Regards, TC
