hey guys, I decided to take the leap and try my hand at building! It seemed like everyone was recommending the 4*series for a first time builder. Everything looks straightforward but I have one question.

In step 4 it mentions to install pre-cut balsa shear webs in each rib bay. The problem is I find no trace of these pieces anywhere in the kit. Even on the inventory sheet (where it shows all pieces drawn out) there is no mention of them. Do I have to go out and buy some balsa and make my own? Or am I just missing something here? Thanks
