I use the wrench but like most said on here... I spin the props till it stops then hold the wrench and slightly tighten it. I use it as it makes me look more technical so hopefully a sexy man will see it and say "ooooo that looks important, I must sleep with you"
So far hasn't happened... Which is just as well as I'm not gay and my girlfriend will kill me
