John covered it correctly. BTW, with that factory muffler tunnel that airplane is not a World Models Cub. It looks identical to one currently being sold on Ebay as a "no name" Cub ARF from a seller named "Lagola" out of Chicago, Illinois. He offers them at a buy it now price of $100.00 plus $23.70 shipping. Looks nice for the price, less than $125 to your door. Enjoy !!!
