This system is built into a plexiglass tube. It comes completely assembled. All you need to supply are a radio receiver (FM, NOT PCM) and three servos. The module comes with the following items:
The electronic components are mounted on two easily removable trays. All internal connectors are of the Tamiya type. 90% of the components are produced in-house.
By popular request we have decided to produce a 3.5 inch diameter module. The standard version comprises of three 8 inch tubes, giving an overall tube length (including end caps and bulkheads) of about 25inches.
The FRONT section houses the + and - input terminals, reversible water pump, solenoid valve and the pump control unit. The latter three mounted on a CNC`d tray. This front tube is attached to the middle BALLAST TANK by three brass tie-bars. The 8 inch ballast tank has two baffles mounted on the central conduit which allows the power and servo cables to run from front to back. The THIRD and final tube, also connected by three tie-bars to the ballast tank, houses the propulsion motor, speed control unit, plus two push-rods for the rudder and the rear dive planes.
The standard unit uses a sealed ballast tank and has been successfully used on the 65 inch deBoer “Seaview” submarine by Steve Neill and the 57 inch Disney Nautilus & OTW Vanguard built by Bob Martin in Florida. This unit does come with a forward push-rod . All push-rods are stainless steel and come with clevises and waterproof bellows.Different length Ballast tanks are available by request.
For further information please contact us and we would be happy to discuss your specific requirements and if there any special deals available.

All prices are Ex works shipping and insurance is extra. We will also make Special Modules on request.
If, at a later date, you want a shorter module with a smaller ballast tank for a different submarine, we can supply additional ballast tanks of different sizes that are interchangeable, as are the drive motor bulkheads.
With this dive system, you no longer need to buy Propel gas (it doesn't use it), and you never need to count the number of times you submerge and surface. Your only limitation is the battery capacity; when the voltage drops to a specific level, the failsafe kicks in (if you are submerged) and blows the tanks - you will have enough power to bring your boat to the side of the pond.
