I’ve found tips here and there in the VEX forum, but I don’t know how to build a DR4B off of those tips and images. Does anybody have “thorough” instructions for building a DR4B?
did a forum search for dr4b guide… DR4B Tutorial by 333A (pretty thorough starting point)
Use thicc gears and a lot of bearing flats, along with the thicker axel if you can.
The 333A tutorial was already linked by DougMoyers, but I included it here to have a nice collection of links for you.
