It allows it to take off and land
The heavier weight of a thicker paper will affect the range of the flight, and different folding characteristics and stiffness will affect the aerodynamics.
I don't know isn't there somebody to answer this?
no.because the designs just make it look better so basicly it do not affect flight
slows the plane down
Yes, because on hot days for instance, paper airplanes can catch thermals.
Yes, weight may affect a paper airplane by increasing its mass. This may alter its glide ratio and change its wing loading.
You will need 1 paper and fold it hotdog then do to flaps then seal it then make wings!!

god
The effect of a hole on a paper airplane would depend on the type of paper airplane the hole is on, and where it is on the aircraft.
no
It dosn't affect the distance.
