I actually have seen that video, it is quite helpful, in fact It answered most of my questions but all I'm really lacking is a suitable ESC to pair with the motor I've choosen that isn't too expensive and preferably has BEC included. I can use the one cornelp suggested if I can't find another good but cheap one that has BEC included.

I don't actually have the boat yet, as I'm waiting to see if I win it since I'm bidding on one on ebay. If I don't win then I was considering perhaps the Rio EP but as you said it's newer but I figured it had to be close to other boats out there of similar size since all I would want to replace wouldbe the ESC and Motor and batterys.
