i'm a newbie to rc boats i'm having a issue when i turn the boat seems to (cavatate) rpms go up for a couple of secs boat doesn't move it does this unless i turn at granny speed tried adjusting prop depth rudder pos/neg doesn't make any difference can't see the turning fin being the problem anyone else heard of this?

A little more info would help on this one. Are you running on a plane or is this when you launch it or what?

Adding the Grimracer turn fin might help as it will help to hold the boat on the water when turning as it will scoop the water where the stock one won't pulling down the right sponson. A lot of cavitation occurs in turns because the right side is lifting on hydro's.
