What is the best material to build a plane out of?

For chemistry we have to build a plane out of a substance of our choice.(It will be 2 by 3ft) but i don't know which material would be best for building it out of.





We are required to make it fly 45ft, but for an A 60ft. Out of the materials i listed below, which would be best to make the plane lift, and fly at a constant speed. It can only be powered by the trust of my hand.





-Thin wood


-Foam


-Cardboard


-Thick poster board





Or are there any better materials? Thanks so much for any advice :)|||Try balsa wood, which is very light. Make a frame for the plane and cover it with paper. You will do just fine.|||In other words, you want to throw a glider to 60 feet. Remember, " flying " means " under its own power ".


Balsa wood would be the best choice. You have to study something in aerodynamics to make a working model. It will be a GLIDER.|||Choose Foam and Balsa wood (THRUST)


========================


nothing else in your list is appropriate





(different grades of balsa wood ...thin sheet, soft, or hard blocks or strips) ribs and spars traditionally covered in tissue or lightwight nylon and doped








Model


Balsa wood





The lightest 'planes that float around in hangars


are made from dope (cellelose thinners ) floated on water


and placed on a minute frame (to make a wing)





Aeroplanes (proper)


Composite


Aluminium
