My E-Revo questions and build

[j-man]

Trays are plastic, shock proof in a temp range of -40 to 80 centigrade. It's an mailbox. lol
They were supposed to have a sidewall at outside and back. And to be an perfect fit to chassis, but as said cutting then in a hurry I cut them from wrond corners of the box, so I made mirror images. Had to modify chassis sides flat and now it has sidewalls at font and back. bummer.
