Re: Incorporating the vex ball shifter into a WCD Drive

Based on calculations with the JVN Design Calculator and input from various sources, I can say without a shadow of a doubt, it will all depend on what you want to achieve.

That said, it looks to me as though a VEXPro Ball Shifter 2 stage will need an extra reduction to get it where you might want it with 4" wheels. Somewhere in the neighborhood of 26:15 or 28:16.

There is a version of the WCP that "should" work for direct drive and 4" wheels.
It is spec'd at 16.4:1 and 6.1:1.

Again, I am NOT an expert on this subject......yet. Please determine your needs and do your own calculations before you make a decision.
