HYDROPLANES (Diving fins or Dynamic Diving) To understand the problems associated with the hydroplane operation it is probably best to give a brief description of how the full size submarine works. When a submarine starts to dive, the fore planes are set to dive and the rear planes are set to surface, this has the effect of pushing the bow down and the stern up. Once the submarine has started to dive then the rear planes are also set to dive. When the operating depth is achieved both sets of planes are set level. To surface the fore planes are set to surface and the stern planes set to dive, this pushes the bow upwards. Once the submarine is angled upwards the rear planes are also set to surface. There are different ways you can operate the hydroplanes according to the type submarine you have and your own preferences, they are:- 1 Fore planes only operational, rear planes fixed 2 Rear planes only operational, fore planes fixed 3 Both planes set to work together from one servo. (Both linked to dive and to surface together or either One set to dive and the other to surface alternately) 4 Both planes set to work independently using separate servos. (Much skill is needed here to control both sets of planes while diving In some cases one set of planes are radio controlled by the operator and the other set controlled by an automatic leveller, a sort of autopilot to keep the submarine level. Dynamic diving model submarines use the diving fins to submerge and surface, the electronics are kept dry in a watertight container. Hatches with watertight seals allow access to charge batteries, change receiver crystals and general maintenance. |
