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.
You can build anything ! but the best will be to build a auto smelter, Here is a link to the tutorial....
I know!
gliders
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
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
Wax paper works good for strong, high-flying planes.
you have to turn one flap up and the other one down to get your paper airplane to do a barell roll
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)
Any plain paper
The type of paper used for a paper airplane can significantly impact its flight distance. Generally, copy paper is the best choice as it is lightweight yet sturdy, allowing for longer flights compared to notebook or construction paper. Copy paper has a smoother surface and consistent thickness, reducing air resistance and providing better aerodynamics for the paper airplane to glide farther.
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.
