Hello! This is the Hammerhead. It takes a standard 8 1/2 x 11" sheet of paper. Few folds, good for beginners.
You could use some tape, but that is completely optional.
Step 1: Halve the Paper
Get yer' paper and Fold it an half.
Step 2: Corners
Now grab the top left corner and bring it to the middle, so the fold is in the right corner.
Unfold. Now take your left corner and bring it to the middle. Unfold.
Step 3: Fold Crosses
Now, Take the right corner again and take it it the left bottom crease.
Unfold, and do the same for the other side.
Step 4: More Folding
Ok. pull up the bottom folds up.
Now flatten them so a Diamond shape forms.
On to the next step!
Step 5: The Next Step
Now fold the diamond shape in half.
Now fold the plane in half, with the diamond down.
Simple step eh? :)
Step 6: Measurements
Now go to the front of the plane and pencil down (or estimate) about 1/2".
For the back anywhere from about an 1 - 2 1/2" will do.
Step 7: Done!
Done! Good job.
You can choose to add the fins on the side or tape bout you can also leave it standard your choice!
Now go fly your plane!
