What are the rules for using old VEX EDR hardware? What is legal and what is not? Can structural elements, gears and other miscellaneous systems that work on the V5 platform be used in the VRC. I know the brains, motors and batteries must be changed, but can I use 5" traction wheels or old liner motion kits? The VEX site does not list a lot of what was available even last year so it is hard to know what is legal or not.
I tried a search on this but nothing useful came up.
