<div dir="ltr" data-setdir="false">Hi Rick,</div><div dir="ltr" data-setdir="false">Are you compensating the thrusters and arm from the same regulator? I would caution you on doing that. I have a theory that putting multiple items on one scuba regulator will not work if there is any distance between items. My arm as I mentioned is working well with the scuba reg because it is literally a few inches from the manifold. The hose connecting the reg to the manifold is 1\2 inch ID. This is the reason I am testing an LP regulator, because I can create as much over pressure as needed to help with distance between items. I agree with Alan, that the water should not get to the motors on the surface, particularly if you have some vertical line right off the reg. </div><div dir="ltr" data-setdir="false">It is sounding like there will be a launch soon?</div><div dir="ltr" data-setdir="false">Hank</div><div><br></div>
