Everyone has the right to their own opinions. While I do prefer the inherent stiffness of an aluminum chassis rig for it's handling benefits, I have also enjoyed the forgiving nature of my plastic chassis rc's as well. I know my Arrma's get just as sloppy with usage as any other brand I have, worse than some, including Traxxas. My K8S has more slop in the upper arm hinges out of the box than my Xmaxx has after 2 years of abuse. The 3 and 4s Arrma's all come with plastic pivot balls on all the links, which is quite poor considering the price. As to the electronics, I haven't really been disappointed by either Arrma or TRX, I cut the plugs off of each without prejudice, LOL. At the end of the day, I enjoy each, some I'd buy again, some I won't..
