This is an original Carl Goldberg Li'l Satan balsa combat and stunt airplane kit for 1/2A U/C flying. This model is No. 23 KIT G12. It is in mint condition still in its shrinkwrapped box. This control line model plane is for .049 gas engines and has a wingspan of 19 inches. The box package measures 4 1/4 by 18 1/2 and is 1 1/2 inches deep. These planes are no longer being made and getting extremely difficult to find in this condition. The Li'l Satan is a great combat plane that would be an awesome addition to any vintage model airplane kit collection!
