Re: 2-Speed Shooter Gearbox

We're using a CIM through a Dewalt for the reasons stated in Andy's post. The math says it'll shave about a second off the spinup time. I think the more important feature is that it optimizes the power output to the shooter. Your motor is limited to 40 amps or so, after all. If you gear it low to start out, you can get out of the RPM range where you're drawing 80+ amps at 12V a whole lot quicker. And you only need to worry about the sequence once if you're keeping your wheel spun up the entire time. Although I really need to check on the current draw to see if we'll be doing that.
