F-50

All we need is an A-4 Paper and some skill

Fold and then unfold an A4 paper

Fold the paper and make sure the edges are on the line that you fold and unfold the paper

Fold one more time so it would be look like pic 2

Fold it in horizontal line so the top would touch the bottom ( pic 2)

Fold the two top edges so it would be parallel with each other and with the middle line

Fold up the plane's nose up to the top

Fold the plane half in vertical

Fold the wing

Unfold the wing then fod the bottom edge so the point of the edge will touch the unfold wing line

Open it wide the put the edge to the back, it's pretty easy but tricky if you don't understand

Fold it like the photo
