Not entirely sure what you mean by growl, but no it's not powered the whole time. I use the two switches on the right gauntlet to operate it. The rear switch is flipped until the stalk is all the way down, then the switch is flipped back to the off position. The front switch is then flipped to move the stalk back up, and then is also flipped back to its off position. Hope that answers your question. I can do another video if that didn't make sense.
Makes perfect sense. I think the switch idea on the gauntlet is a really cool idea!
