Just a quick question, I picked one of these up from an estate sale, while it was mostly complete it is missing some key pieces. It is missing both elevators, the rudder and the flaps. Can someone point me in the direction of someplace where I can get the size balsa I need to be able to cut the control surfaces out in 1 piece, I have bad thoughts of an elevator that is pieced together breaking mid flight. The widest I can find locally is 3" wide, but that is in no way wide enough to make the elevators. Any help is very much appreciated.
