Question: What is the Best RC Submarine Diving System, Dynamic or Static?
One of the key features that sets RC submarines apart is the method of diving. The two types of RC submarines are dynamic divers and static divers. Dynamic divers use speed and power to get underwater. Static diving subs use weight to go under.
Answer:
Dynamic Diving System
With dynamic divers, the subs use their control surfaces (the fins or hydroplanes) and speed to force them under the water. If they slow down or stop moving, they return to the surface. RC subs with a dynamic diving system typically have a 3-channel controller for throttle, diving planes, and turning (rudder). Other channels may be present to control added features such as lights or periscopes.This type of diving system is found in most toy RC subs and in some hobby-grade subs.
- Dynamic Divers Are Best Choice For New or Young Captains and Beginning Modellers Because: Dynamic divers are simpler to control and easier to build.
- Dynamic Divers Are Best Choice for Dark or Deep Water Because: If you lose power dynamic diving subs bounce back to the surface (unless snagged on the bottom).
Static Diving System
Static diving RC submarines have some means of changing the weight of the RC such as by filling ballast or dive tanks with water. This assists them in submerging. To return to the surface the sub dumps the extra weight in order to regain bouyancy and return to the surface. Static diving systems may use electric motors, pumps, or some form of compressed gas to fill or empty the ballast tanks. Static divers will have a minimum of 4 channels on the controller including a control for the ballast (adding and removing weight) as well as extra channels for torpedoes or other added features.- Static Divers Are Best Choice for Experienced Captains and Modellers Because: Static divers can be trickier to control and more complicated to build and maintain.
- Static Divers Are Best Choice for Pools and Clear Water Because: If the static diving sub loses power it sinks and can be more easily relocated in clear water. (Note: However, the air bubbles created from purging the ballast tanks can help locate a sub trapped on the bottom.)
There is no single best choice of RC submarine diving system. Choose the one that fits your skill level or try different systems for different operating conditions.
