lol: do some research bud.
years ago they made propshafts on cars out of bar, they would twist unless they were REALLY thick and very heavy, a tube of the same diameter with a very thin wall (1mm) is just as strong and will resist and bending.

Yes, fact im afraid, it will resist the torque and not bend, strange but true, thats why all car props are made that way, makes them much much lighter than solid aswell.
