Hi all. have got a kyosho ATLANTIO 6000 CRUISER (may be called atlantic cruiser in U.S)it has the standard motor in it(mabuchi rs550sh) and standard prop(d34 x p0.8). The boat currently has a ripmax no limit speed controller fitted and runs on a 7 cell battery(8.4v). can anyone suggest an upgrade motor and larger prop to suit. not to sure what it all means about turns and brushless etc.ta
