demonstrated the thruster today at the marine science workshop i was participating in and it puts out some serious thrust and I only took it up to 3 amps with a two bladed prop. I think it will work good for a small rov i am trying to develop for youth to use offshore and off the dock.

I am thinking of beefing up the thruster mounting point and possibly adding another mounting point for the vertical thruster as it may experience more stress when hanging in open air. I use Creo Direct modeling express and have but not used DesignSpark Mechanical. Would it be possible to post an 3d cad file that is compatible? I am not sure how to modify the actual .stl file, I would like to try some modifications on your design.

thanks

BTW i just tried the thruster with 5amps, and fwd thrust is pretty darn strong!

Steve,

What size are the props? I know 50mm, but what diameter? Right or left? Pitch?

Thanks

The Diameter is 50mm and they have a 42 pitch. They use to come in both Left or Right hand but it looks like they are only availble in Left now. (At least from Harbor Models where I use to get them from.)

The left and right is kind of tricky though because what we call left in the States is actually the opposite of what they call it over seas. I've had problems with ordering the wrong ones in the past.
