Need input on a chassis im making

[rootar]

the 6061 T6 i think will be more useful to me and i can get 6 times more of for less than the carbonfiber, the ebay junk is polyester resin which i even know isnt the right way to make carbon fiber rigid, you have to use a good epoxy resin and the good stuff cost to much. ill try and order the 6061 .125 T6 tomorrow through the college and get their discount.
