As you may not know. Radio communication under water will in most cases not work. Google the term "underwater radio communication" you will find many interesting papers
So unless the OP use it in a pool, the sub will probably be lost in action.For the basic 27 to 47 mhz transmitters, they can work up to 3 feet deep in water. I have a radio controlled submarine that can submerge but only to 3 feet deep, after that the controls start malfunctioning and it has a tendency to just keep going on its own
yeah, using it in open waters would not be recommended!! That is why most submersibles used in open waters are tethered.....So unless the OP use it in a pool, the sub will probably be lost in action.
