I'm not sure what you mean by "need" since weight is a concomitant - everything used to construct an aircraft has weight. It's a fact of life.
Aircraft designers do everything possible to reduceweight.

How would you redesign your paper airplane to make it fly faster?
You can get a plane to fly faster (for a given force applied) by decreasing drag, e.g. reducing the width of the fuselage or wings (the latter also reduces lift). If you add weight to a paper plane, especially at the nose, you can get it to fly faster for a given acceleration (i.e. the throwing motion) -- the additional weight will increase the speed gained as gravity drags the plane down, because the air resistance is a function of the area, not the weight. A metal plane will fall faster (and with a higher terminal velocity) than a paper one if they have the same resistance area.
How much lift does an airplane need to fly?
It depends on the mass of the plane. The heavier the plane, the more lift it needs.
How old do you have to be to fly on a airplane?
you can be any age to be on a plane. to be on a plane alone and not an adult you need paperwork and stuff saying you are an unaccompanied minor

What do these 3 words have in common weight fly and sand?
The words weight, fly and sand have "fly" in common, because together they can form other words. Their direct relationship is: fly, fly weight, and sand fly.
Why does nose weight make a plane fly farther?
It makes the plane weigh more.
How do you make you fly?
You can't fly. You will need a jet pack or plane. there is no other way
How do gliders fly?
Gliders are pulled by a small plane into the air and then the gliders move around catching air currents from the heat.
Can a plane fly when all the forces are equal?
well it will need to make the forces unequal to take off, but yes it can fly with them all equal.

How does nose weight help a plane fly?
Nose weight often helps to bring the wings into flying attitude.
