I've been thinking that my boat doesn't turn like it should and been wracking my brain for ideas.
Bear in mind that electric boats are very new to me so I am very much in a learning curve.
I'd come to the conclusion (based on no knowledge whatsoever) that the rudders were the wrong shape, too wide and not deep enough. That was, until last night, when I waded through everything I could find on this forum about rudders and props.
I'd fitted my props in the conventional way, looking from the rear, left going anti-clockwise and right, the opposite. I found a comment or two on here advising that if turning was problematic, try running the props in the opposite direction (left - clockwise right - anticlockwise).
Well, what a revelation. The boat turns now like it was on rails and full-speed turns are without drama.
This is one happy bunny
