4.25" OTW Dive Module - DUAL SHAFT
The front section houses the positive and negative input terminals , reversible water pump, solenoid valve, the pump control unit and forward push rod. The latter three are mounted on a CNC`d tray. This front tube is attached to the middle ballast tank by three brass tiebars.
The ballast tank has three water probes which control the pump and the fail safes. Baffles to prevent tank sloshing are 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, has its own CNC’d tray and supports the propulsion motor(s), speed control unit, and two push-rods for the rudder and rear dive planes.
All push rods are stainless steel and come with clevises and waterproof bellows.
All OTW Dive Modules run on 12 volts and have two fail-safes incorporated as standard (low voltage and loss of radio signal). All wiring is connected with Tamiya plugs. Single and dual motor options are available.
Dive Modules come fully assembled and tested.
The module comes with the following items:
- Two drive motors complete with motor mounts and waterproof shaft housings for the propeller shafts.
- A speed controller rated up to 30 amps.
- A BEC, which allows you to run the whole system AND the radio off a 12V battery.
- Reversible water pump and hydraulic valve.
- Electronic pump management system that is complete with two failsafe modes.
- Three ballast tank probes.
- Three stainless steel pushrods and clevises.
