Introduction: 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!

Hmm Maybe you should make a step on how to make the paper airplane.

author

 Just about any paper airplane will work.

author

 I'll try to satisfy you though.

author

 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.

author

 Nice! Sounds pretty cool.

author

 mine shot about 650 feet

Hiyadudez (author)KnexMaster70002010-02-04

Im sorry. You did not get 650 feet. No way. If so, I need video proof.

author
KnexMaster7000 (author)Hiyadudez2010-02-05

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

KnexMaster7000 (author)KnexFreek2010-03-17

i guess seeing is believing. but i dont have enough grey connectors :( and everytime i go to knex.com they are sold out of JUST that piece... and thanks for lookin at all my guns haha

Hiyadudez (author)KnexMaster70002010-02-05

Dude, if you are saying that you dont know the first thing about knex guns.

KillerK, the original maker of the TR sot of 300ft with finned ammo and he has video proof. So how about you shut your mouth!

KnexMaster7000 (author)Hiyadudez2010-02-05

 well next time don't say stuff like that just to make people mad. you were pretty much fishing for a argument right there. 

author
KnexMaster7000 (author)Hiyadudez2010-02-05

 yeah dude believe me. im not going to waste my time to make a video with 3 feet of snow on the ground. even ask knexfreek.

 bump look down and he the spirani with 11 # 64s

author

here is what it looks like. if you make it put tape on the back of the plane on the redconnector, and a piece in the front.

 if theres too much weight in the front, depending on which type of plane you built, just replace the grey rod with a shorter one.

 i once made the same thing only i had a bended paperclip on the front so that it doenst push but pulls the plane forward.
It you do that it can get more speed without destroying it!

PS: the paperclip was bended like a S and stapled on the plane

author

 I guess that would be even better! Maybe you could post it sometime.

author

 I made one! And like every man, i made a gun out of it.
And it can both push and pull a plane

 Cool!

author

 idk maybe

hope keeps living

author

 You could also put tape on the plane's back to stiffen it.

 WOW awesome!!!!!! switch the 1st pic with the 4th pic on the intro page :)
5 stars and FAVED!!!! GREAT JOB! THIS IS A FIRST IN KNEX :D

KnexMaster7000 (author)KnexFreek2010-01-21

 first instructable that is. if you followed the arguement with like 15 people on my instructable for the avalancer f22 i made, you will see how i made an airplane bullet for the sipriani rifle series.

author
dsman195276 (author)2010-01-20

I had that idea a while ago, but was to lazy to do anything with it, good job for actually making it!

author

 I suppose to reduce damage to the airplane, you could take off more connectors. But, then again, you would lose some power. Your choice, Mr. Muggle.

author

 Thanks for the advice, kNeXFreek!

author
Mr. Muggle (author)2010-01-19

pretty cool, though I think if you'd use too much rubberbands the paper would cut
