You don't need 1/4" plate.. Yes, it is more stable for gearbox application, but I have done my share of research on sheet metal gearboxes and 971 does just fine with what it looks like .090". I looked through their entire album and they use A LOT of .090 for the chassis. Granted I will have 2 more motors per gearbox.. Either way. If you don't believe have a look for yourself. If it is not strong enough, I will A)Put a flange on the plate B)increase the thickness to .125" C)Do Both.

With 8 motors I am trying to get more acceleration (mainly), and more pushing power. Spectrum ran 8 this year and really liked it so I figured I would give it a try. If it doesn't work out I will go with 3 CIM
