I forgot to list one very important item I have for this uboat. I have the OTW dive module.
Dive and Leveling Systems
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:
•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.
•A pitch controller, which keeps your submarine straight and level underwater.
•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.
•Three waterproof silicone rubber bellows for the control rods.
•Two waterproof external battery connectors, one positive and one negative.
•A set of three baffles in the ballast tank.
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.
Price reduced to $3000. This is less than I paid for the kit. Oh, and the torpedo system has been tested and fires perfectly.
