2.5" Diameter Easy Driver - Dual Shaft
  • 2.5" Diameter Easy Driver - Dual Shaft



    This Easy Sub-driver (SD) when outfitted  with the appropriate devices, is specifically designed to power and control any one of the many intermediate to large sized (between 35" and 50") GRP and plastic model r/c submarine kits currently available through the normal retail and auction sites.


    Of the 'dynamic' type, this SD does not incorporate a ballast sub-system -- meaning that the model submarine has to be trimmed heavy. When floating dead in the water, only a portion of the models sail will project into the air. The models depth is controlled dynamically; the forward motion of the model submarine through the water, and the angle it is commanded to assume to the water flow, dictates the rate at which the submarine will dive or rise.


    This Sub-driver, being a removable system, can be employed in any number of model submarine hulls -- an economy not shared by models constructed with the devices fixed within the models hull.


    Two shaft model submarines can be operated with this Sub-driver: Two counter-rotating shafts -- each coupled to its respective 360 size, 12-volt motor through a 3:1 gear train -- produce plenty of torque.


    An antenna extension kit and instruction pamphlet is provided to permit submerged operation of the model when using a 2.4 gHz r/c system. The SD is also outfitted with an external 27-75mHz antenna for those using the 'old' FM r/c system.
