Re: RS-395 safe loading

According to JVN calc, I'm gearing it down 74:1 and that results in a 210RPM free speed. It draws 4.1A under typical load, that is, all 4 wheels on the ground on a 150lb robot. When sitting on two wheels it's loaded at 7.6A.

Is this a safe current to run through an RS-395 through a match for a swerve drive, or should I stick with a 500-series motor?
So your savings overall would be 1lb?
It really doesn't sound like it would be worth it.
