Re: 80/20 frame Material Questions

One thing to keep in mind with 80/20 type materials is that they have terrible torsional stiffness compared to a box tube. We used mostly 80/20 for the stack attack game robot. That year the weight and constantly having to tighten the whole robot turned our team off to 80/20. We have used the left overs for fast prototyping since then. Now we use mostly angle and plate 6061t6 aluminum.
