id install this one http://www.horizonhobby.com/Products...ProdID=PRB2314 to be sure

50A forwards 20A reverse, waterproof, 4.8-12v, BEC enabled, no fiddling around with a set up button either, plug and play.

I run one of these in a Najade on 9.6v feeding a Robbe 710/12, no issues what so ever! only reason it was replaced was water got in the boat and rusted the switch, so I replaced with another one, (the only difference was the box was purple not blue).
