Re: pic: 176 Prototype 6WD Rev. 7
That will be one tough chassis.
From our experience I'll point out some things to be aware of.
1) IF you can weld, box tube is lighter, but not as convenient.
2) The wheel mounts may work loose and slide in the 80/20 rails. Make sure to fasten them securely!
3) Impacts will cause the frame you show here to loosen and shift. Make sure to through bolt or gusset your corners and joints. (Again, this is where welded box tube can be superior.)
As long as you plan ahead for the rigors of competition, this frame design should server you well.
