is there a way to shut off the motor on 1/12 budweiser? other than lowering the idle screw till it dies? newb at boats electric planes are my thing but goin for nitro boats now. its probobly a simple answer but i just want to make sure

You can pinch the fuel line for a few seconds. Or you could also plug the exaust with your finger to stop it. I prefer to plug the exaust because it is very quick and easy.

I plug the carb also, but my OB is a open carb

awesome thanks

Instead of squeezing the throttle trigger on the radio to go faster, push it outwards to stop it, like hitting the brake on an electric car. If it doesn't, then adjust your throttle trim or the idle screw.
