Carefully draw the aircart sides on a piece of corrugated cardboard. Use
an erasable pencil so you can correct mistakes, and pay attention to the
dimensions. The two sides are not the same, they are mirror images. Cut
them out and score (cut one layer only) at the fold. Glue the tops together
with the hot-glue gun and bend out the sides to form an upside-down Y. The
top portion of this piece forms the support for the propeller guard , so
they should be solidly glued all over to make a rigid vertical support.
