This is one of the most complex models I have built. From an original Tug, this Research Vessel is equipped with a working gantry and winch, and a port side crane. It is capable of lowering a FPV submarine off the stern, and a shark cage with a diver inside off the port side.
It has a leak in the prop shaft, but a bulk head contains the water in the aft of the hull. A float switch activates the bilge pump (or harsh braking) It has internal, deck and nav lights. An FPV Camera on the bridge and runs on three sets of batteries.
Internal cabin lights can be turned on remotely, but bridge lights are manually turned on.
It has an Amber strobe light for diving operations and a remotely controlled PA system for announcements and warnings.
Power supply:
1. 12V SLA for motor
2. 12V SLA for bilge pump
3. 6V SLA for Lights and RX
Scale is 1:48
