I completely understand that. But my point is, 7075 T6 aluminum does not bend. At all. Especially as easily as his was. He tapped it a few times with a hammer and it bent right back into shape. No 7075 T6 would ever do that. I have machined semi loads of 7075 T6, and would bet every last RC I have that the EXB chassis he had is a poop grade of aluminum, if it even is 7075. Hell, I filled up a 56' box trailer of just shavings of it off a mill in two weeks one time. 7075 T6 absolutely does not bend by smacking it with a hammer.
And Kevin even verifies that when he lays into an M2C chassis made of good 7075 T6 and it didn't bend a bit. And it doesn't matter if he ran over it with a bulldozer. It would have been broken, not bent.
Start watching at 2:40 in this vid...
Kevin is actually a very smart guy if you pay attention in some of his live streams. He knows metal. Probably not to the extent I do, but welders are no dummies. And he is a damn good welder.
Just sayin.
