The VersaPlanetary set up is this:
  • Banebot 18V motor as input (crazy overkill but when you are building a robot in 3 days you use what you have in hand and once you find a thing that works, you don't change it unless you have to).
  • 4:1 stage 1
  • 5:1 stage 2
  • 1/2 hex output.

I love the versaplanetary system. I think they are a huge help to teams prototyping because it is so easy to change the motor or the ratio or the output shaft. I've got no financial stake in the product or company, I recommend buying a boatload of ratios and output styles (1/2" hex and 1/2" round are my preference).

Calling 'em like I see 'em.

Dr. Joe
