How does the model get the radio signal when its underwater?
Photo by Antoine Lenormand We aren’t worried about the technical details. We do know the radio signal penetrates fresh water, as deep as most people are willing to take their boats. Heavy chlorine content in a swimming pool will limit the signal depth depending on signal strength and frequency. Salt water is pretty well impenetrable given the typical low power and relatively high-frequency of the R/C units. Crafty sub modelers have figured out ways to run their boats in salt water by allowing the radio receiver’s antenna to remain above the surface.
