Thanks Tony on cking on how it is going with the build. I have to say I do not know at first what" a thruster was but I finger he was talking about the about the Propeller's because in one photo, that I had shown it to have the plastic propeller in the photo, when I saw that! than I know what he was talking about..He was just pointing out how much more thrust I will get with Brass Propeller's over Plastic one's. And I was just letting him know that was ordering some brass thrusters/ Propellers.. I hope I help here to clear the air. And again Tony Thanks man. And while I am talking about Brass here is my Anchor winch, That I had to make only because I drop the one that came in the kit, and of cruse it got damage a good bit so I made a new one, so here is some photo's on that.
