Well i was going to try using the walmart motors that are geared and waterproof for a scratchbuilt sub. But how do you make a hull scratchbuilt that even looks like a sub. All the ones i make is like a bottle with motors. But what i was going to od is waterproof the 1 or 2 chips and make a divable sub. Im trying to make a scratch built ballast tank out of a nasal spray bottle. I dont know if its possible. Also is there a way to salvage the walmart seawolf's body. Like buy a good radio and hook up some micro servos from rc airplanes and make bowplanes for it. Once i get the money i will try this. And are there any good 3ch radios that wont get wires ripped off of them. I cant seem to not rip any wires from rx's.
