Step 2: Making the Paper Airplane

This is a simple paper airplane I chose, but you don't have to use this design.  Most paper airplanes will work if they are designed for going fast.  If you do plan to use a different airplane design, make sure you have the opening where the rubberbands will hook on to.

Step 3: 45 Degree Angle Paper Airplane Launcher

This is the 45 degree angle paper airplane launcher.  Your airplane will get a lot of distance with this launcher.  Follow the pictures and image notes to build this.

Step 4: Vertical Paper Airplane Launcher

This is the vertical paper airplane launcher.  You will get a lot of height with this launcher.  Follow the pictures and image notes to build this.

Step 5: Safety Precautions

Never aim the airplane at a person or animal, especially in the face.  Right before launch, look at your surroundings and make sure there are no people or animals around you, because if the Knex launcher misfires or the airplane is taken by the wind, it may hit someone.  I am not responsible for misuse of this launcher.  Use discretion on how you use this.
I am not responsible for lost or damaged paper airplanes.
