quick question to all about why using KOP metal.

[Torboticsmember]

Our team used the KOP chassis last year, and were fine with it. Which is why we are using it again this year.
We weren't very aggressive but the few times we were it held up for us fine.
If you put it together properly than it is very strong.
Time is a big reason for us, knowing our team it would be a week and a half to design the chassis and another week to actually build it (exageration of course)
and finally money is a big issue with so much other things that don't come in the kit we don't have the money to go buy another frame to be made.
