RE: Any suggestions?
Are you running in a weedy area? If so, a boat with any type of submerged proppeler may pose a problem. Otherwise, if you want to insure that you wont loose your boat, run high mah nimh cells, like the Epic 3000's, that way you can bring the boat in when it starts to slow, yet you wont need to worry about discharging the cells. Also, a 3000 should last you well into 10minutes of run time.
