change from the arrow paper airplane

original

 

hard paper - more weight, can fly faster
tip is too heavy, cant stay long in the air
need throw hard

make the head more strong and heavier which can throw further

cut the end of the wing - give a good balance
can hold longer in the air

Flip the wing up, make the direction more straight
the other design keep the same

Fold a small wing at the middle end - keep the plane more straight
small piece fold at the flip wing - can hold the wings more stable and balance

Same design as above just use stronger and heavier paper
can throw far but stay less time than the one above

used a medium paper - best result then the above two
