This is a very old and rare kit built rc airplane designed by Carl Goldberg. It is called a Skylark. The original kit could be built as either a twin engine or a single engine airplane. It is thought by many that only about one hundred or so were built as twins and out of those roughly thirty have been confirmed to still be in existence. Two hs81 servos operate the throttles, four power hd1501s operate the flaps and ailerons and two standard Futaba servos take care of the rudder and elevator (I will replace them both with Power HD servos soon). The engines are Magnum XL .28s and are supplied fuel via two four ounce tanks.
