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

 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!

no way the creator is still active after knes died
Could you do a video on how to make this and put it together the images are hard to see some of them
I haven't had this built in a long time, honestly if I were to revisit the idea I would make it differently. Really the most important part is getting the rail spacing wide enough to hold the plane without pinching it. Rubber band tension if too strong will mangle the plane rather than launching, though a bit of tape on the back can help strengthen.
I wish you the best and happy building!
Is there anyone on Instructables anymore or is no one responding?
if i could have one i would turn it into a crossbow :333333
Hmm Maybe you should make a step on how to make the paper airplane.
 Good idea, although the plane is not too hard. the basic principle is to fold it in half longways, then fold the top two halves over to the middle crease. Fold those tabs over and the plane is complete.
 yeah i have a airplane bullet that the rubber bands hit like this but dont crush through the paper. i even used 11 #64 rubber bands.
Im sorry. You did not get 650 feet. No way. If so, I need video proof.
and if your gonna rad on me about what you think, then im gonna rad on you about how i know you didnt get 235 ft with ur TR18 with red rod with wings. ive built it and used that ammo and didnt get close. so if i were you, i would take that out of the instructable and shut my mouth. 
 Actually... tr's EASILY get that range with red rod+fins. And there is tons of proof!
You should make one!!! They are great!!!! XD
