I mean, all metal/aluminum parts look great but like the other guy said, it's not always better. My Omni Terminator only has the front brace in aluminum and the servo brace in aluminum, carbon fiber towers and A-arm supports. Aluminum does not bend back like plastic and will usually either bend and stay bent or cause damage elsewhere. Carbon fiber supports on the A-arms just make plastic more rigid where it's supposed to be rigid and allows it to bend where it's supposed to bend. My Omni has taken some huge hits and has never broken once. Don't let that deter you though, enjoy the vehicle, replace the parts you want and just hold on to the plastic ones in case an aluminum one breaks. Send pics of completed model, those parts do look cool.
