Obviously I am quite the newbie to electric boats and RC in general. I have to questions. What is the deal with brushless motors. Why are the so nuch better? Will a 540 brushless go that much faster than say a 700 brushed? The other question is about ESC. I know it is an electric speed controller, but what kind of programming do they require? I know you adjust the idle but what else do you have to program. And why are brushless ESCs so much more expensive?
