HOW TO MAKE "Mark IV"

1. Cut the parts out of the paper and glue them together along the 'FIGURE CONSTRUCTION OF "Mark IV"'. To make the paperplane beautiful, be conscious about the cutting lines and the glue reference ones. "The ballasts (for the next day)" should be glued if it doesn't fly well at the next day or later. Glue drying may let the paperplane imbalanced sometimes.

HOW TO FLY "Mark IV"

Throw "Mark IV" softly avoiding its attitude declared,and your hand should move as if it is on a straight rail.

If it doesn't fly straightly, check improper twists, bends, and waving on its body, wings, stabilizers, and fin, then fix them straight and flat again.

In case, your checks and fixes do not work, your "Mark IV" needs one or more ways of following special settings depending on situations.

Don't worry! It's easy.
