As I said before, this is going to be a difficult build for me, but I do know how to hinge.
On the front of the elevators and the back of the stab glue a 1/4 to 3/8 piece of balsa the same thickness and length, then bevel it and then cut your hinge slots, but don't glue them in until after you paint them and your ready. Thats it!
