From the title, I'm sure you can tell that I'm absolutely ignorant about what this part is or how to replace it. Basically, I have a few gliders with broken bits that are supposed to make the gliders glide. And because I have no idea what this part is, I've taken a few pictures.
I'm wanting to fix these parts, but I don't know the name of the part and, consequently, where to find them. Brah!!!!
