Introduction: K.P.L. (Knex Plane Launcher)

By
About: I love building. A mechanical engineering student, most of my instructables involve modeling projects, K'nex ball machines, and Lego creations. I am also a model railroader, and I enjoy science (astronomy is m…

 Have you ever wished for a way to get your paper planes to go farther? Now you can with my K.P.L! My first model of it, the V1.0, was so powerful that it launched the plane extremely hard. V1.0 is not for firing at anyone!

V1.1, however was a slightly gentler approach. The only thing you do to the V1.1 (which I documented) to make the V1.0 is to add three yellow connector segments to the barrel. So let's get started.

By the way, this thing was so powerful that it automatically  pulled the trigger, so I just took the trigger off. You'll see how to fire later.

Step 1: The Barrel

 This step will show you how to build the part in which the airplane will sit. Remember, for the 1.0, you need three extra segments.

Step 2: Firing Mech

 Basically holds the rubber band before firing. Really simple.

Step 3: Rubberband Placement

 How to place the rubber band, obviously!

Step 4: Bipod

 The bipod placement.

Step 5: Firing and Range Stats

 How to load and fire, and a taste of the power I got!
