The Kingcobra is a fast, sleek, long range origami interceptor paper airplane with the unique capabilities of hopping and sitting.

TAA USAF Designation: F63-1

Step 1: Materials

Required:
1 Piece of 8.5 by 11 inch paper
Tape 
Optional
Pencil

Step 2: Start Folding

Start with folding it length-wise ("hot dog"-style). Then fold the corners in. Now fold along thecenter again. 

Step 3: Fold Again

Fold the tip to the center. Then pull apart.

Step 4: Fold the Nose

Fold one side back in as pictured. Then fold them together.

Step 5: Fold the Wings

Start folding the wings. Fold each side down equally.

Step 6: Start Finishing the Wings

Now give the wings a dart-like leading edge.  Then repeat on the opposite side.

Step 7: Security Fold

Now fold as pictured so the paper secures itself together. Fold it around the bottom and then you can tape the flaps down, though this is not required but preferable.

Step 8: Winglets

Time to construct the vertical stabilizers. Fold each equally.

Step 9: Flight

Launch the Kingcobra like you would a normal dart. Enjoy!
Whoooo!!!!!!!!! awesome plane "wolf whistle"
<p>relatively good interceptor, I use this as my standard interceptor plane</p>
<p>A newer plane you might be interested in as an interceptor is the <strong><a href="https://www.instructables.com/id/How-To-Make-The-Strike-Ultraceptor-Paper-Airplane/" rel="nofollow">Strike Ultraceptor</a></strong>.</p>
<p>Step 4 is where I was confused.</p>
<p>In that fold, you pull the paper into itself so the tip of the nose overlaps with the other ends of the corner folds.</p>
i am not understanding step 3
In step 3, you pull the tip of the nose to the wingtip.
cool,can i add elevators or other things to this plane?<br>good job by the way.<br>
If I recall correctly, elevators are difficult to place on the Kingcobra due to the curvature of the wings. <br><br>I suppose you could try, but the only additional surfaces that I know for certain are applicable include rudders, spoilers, spoilerons and air brakes.
Do us a favor and highlight sides, folds, and corners and label them. Ex: Corner A folds to point B or Side C folds to Line B. These instructions are very hard to understand and the pictures are fuzzy and hard to see. Some highlights and labels would make this VERY clear.
I am aware of the shortcomings of this instructable. At the moment I am very busy with other projects, but I will try to redo this airplane's instructable as soon as possible.
Looking forward to it :D. This plane looks really awesome. I tried to make it but at about step 3 I just got really lost.
What's the size of the Paper?<br /> <br />
Standard A4 <br /> 8.5 in. by 11 in. paper
no offense intended but 8.5 x 11 is letter size not A4<br>
Remedied. :)<br> <br> <br> <sub>It was quite a task too, as it affected a majority of my instructables.</sub>
i carried the same misconception for the majority of my time in origami, until about a year ago! :)<br>
Prior to your comment, I had seen no indication that A4 wasn't 8.5 by 11 in. paper. Quite the contrary in fact. So thanks for the help. :)
These instructions are kinda hard. I am working on an instructable<br><br>
WHAT?? THESE INSTRUCTIONS ARE SUPERB, MAN.
&nbsp;the instructions are not clear and useless<br /> <br />
<p>This is about as clear as it can get. Once more how are they &quot;useless&quot;? They show you how to make an excellent plane. If there is some part you don't understand, I can help you. If there is a step you feel could be elaborated on, please tell me and I'll see to it that it's revised.</p>
WHAT DO U FOLD ON STEP 4
You fold what you folded in Step 3 between the paper of the corner folds. :P
Useless instructions.<br /> Please restructure the comments! Like you could elaborate on which side should be facing up etc.
<p>I&nbsp;have explained all procedures in how to make this airplane. This step has three pictures and their notes covering them. This is very simple and if you use before and after context you can solve it. <br /> <br /> I cannot make this step any simpler,&nbsp;sorry.&nbsp;</p>
Ok, well thanks anyway.<br /> The planes look amazing!<br /> Maybe I should just put a bit more time and effort into it!.. When I get time :)
