I agree with the logic you are stateing. I would be the first to admit I know very little about the SFG. Thus the reason for the post. Thank you for the reply. I learn something. I have a 1/4 Balsa Nova and it will knife with easy and has really good control. I look at the fuse and it is a sim thought to the one you have in your post. I think I am going to add the SFG around an 1" and mod a balsa fuse around 1" above the turttle deck all the way to the front to the fire wall.
