Thanks sniper67 for the reply,
Think we are both tinking kind of in the same direction.I have the motor directions pretty much figured out,they of course need to run in the same matching direction on each side of the tank.In theory they being motors of the same kind and ratings,should be fairly close in the RPM range.(what ever the specs are for a motor costing a dollar or two to make)Knowing there will be a slight miss-match in RPM's,I think that may not be a problem for the motors or the main boards.(guessing here).

My two major question's would be (1) will the little board have the power and ability to run 2 of the main boards. (2)I plan on using 2 batterys,one to each board.Seeing the little board must get its power supply from the big board,will there be some kind of conflict between the two main boards and using just one of the little boards connected by a Y harness.Guess I'm wondering if the signals can get messed up trying to do this,and smoke a board.
Was hoping one of our tech-guru people who understand these boards,and there workings could give me some technical advice here if they happen to see this post.Trial and error is not the best way to go sometimes,but may have to go that route to find out.I think the Idea is good as far as what I want to achieve,but don't know if the controls are going to co-operate with my plan.Man I hate to see things smooking in the tank,it's usually always bad new to the pocket book.
