I would recommond looking at the Sabertooth ESC. I run the smaller one in my towboat. In mixed mode the throttle stick on the transmitter with throttle both motors at the same rate then when you move the "rudder stick" it will reduce and one motor speed all the to full the other direction. Then use the alerion stick for rudder control. I have had this ESC for over two years now and has worked like it should with no issues.
