Hey thanks for the thread! If I had not been reading up on your build, I myself would have left the rear tank mounted 180 out! Good Idea about the brass tube. About the rudders, I found it not to bad to recover them, and you'll have to use 1/4in x 1in balsa to have the right mount of bite for the hinges. I found that w/o the covering it was easer to get my angles to cut the balsa. But hey there are always more than one way to skin a cat!
