That depends on what you want it to do. There is no best real airplane, much less a paper airplane.
It depends on what you mean by "best paper airplane". The longest time aloft for a paper airplane is 27.6 seconds, thrown by Ken Blackburn and verified by Guinness (indoor flight). Tips for a good paper airplane are at www.paperaeronautics.org/tipsforagoodplane .
make the airplane but attach a paper clip at the front!
Any plain paper
printing paper or plain white paper
copying paper or printer paper will be fine.
The one I find the best is the best paper airplane in the world. http://www.zurqui.com/crinfocus/paper/airplane.html
I know!
The dragon :D
The kind of paper chosen to make a paper airplane affects its weight. The best paper for making airplane is the light but firm paper. Firm paper prevents the paper plane from crumbling in the wind.
The method of launching a paper airplane can vary between models, and it is likely best to analyze the aircraft's instructions for such methods.
amari says a square
gliders
It depends on how you throw your paper airplane. Also how you make to paper airplane.
Okay so the best paper airplane in the world well there is alot there is the skyhawk the omniwing the wetbat and the crustmatic and all of theses planes are very very good
this is a link to a very good airplane model. It will take a little bit of time to fold it 100% accurate but with a little bit of practice it is the best paper airplane. http://www.zurqui.com/crinfocus/paper/airplane.html
Generally, this is a matter of individual preference. It is unlikely that one paper airplane design is the best at everything (range, speed, glide ratio, etc.). Many airplanes are claimed to be the best, but these claims are unsubstantiated.
That very much depends on what you want it to do.. For a graceful kind of glider I would recommend the Floating Paper airplane. For a fast kind of dart I would recommend the Bottlenose Paper airplane. For a good all-rounder I would recommend the Rapier paper airplane. Instructions are linked below for making these.
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.
There are many places where one could find tutorials on building the best paper airplanes. One could try sites such as YouTube for video instructions on crafting a suitable paper airplane.
Wax paper works good for strong, high-flying planes.
Construction paper will probaly fly best because it's thinker
i would say 8 1/2 X 11 graph paper
The range of a paper airplane varies by model.
i think the construction paper airplane will fly farther
If it is too heavy, it will drop down. If it is too light, It is vulnerable to the slightest gust of wind. It is best to make it in-between(the average weight of a paper airplane)
