The History
The Düsseldorf fire-fighting boat was developed and built by the Rheinwerft company of Mainz-Mombach, and it is operated in the Ruhr industrial region of Germany. The vessel is designed specifically to cope with disaster situations, such as a ship on fire, a major oil leak or a harbor system in danger of explosion, and its fire monitors, operating at a pressure of 10.5 bar, can hurl water or foam 145 feet high and a distance of up to 310 feet. The two V-12 engines produce a total of 930 kW (1260 BHP), giving the boat a maximum speed of around 23 mph.

The Model
The Romarin kit of the Düsseldorf fire-fighting boat is large and capacious enough to accommodate all the equipment required to emulate the wide-ranging facilities of the full-size vessel. Optional working systems include the fire monitors, crane, anchor winch, radar, searchlights, blue light, horn and siren, and also the sound of the diesel engines. The plastic hull is moulded in thick-walled material, and it offers plenty of space for the numerous mechanical and electronic parts required for the auxiliary working systems. The model is propelled by two proven MAX Gear power systems, giving it an impressive turn of speed. Four large rudders guarantee extreme maneuvering capability both forwards and astern. The fire monitors can be swiveled horizontally and vertically from the transmitter, and with the recommended electric geared pump they can fire a jet of water a distance of 20 feet. If a working boat crane is fitted, the vacuum-moulded rowing board can be raised, swung outboard and lowered to the water in true scale style.

The TD SR12 receiver is equipped with a triple antenna (2×2.4G & 1×900M) design that provides multi-directional wide coverage for the remote signal and is designed for RC users who want to benefit from resilience and long-range in their radio communications.
TD SR12 also provides a socket that can be used to connect the NFC Switch panel to enable the built-in Power Switch function. Dual-power provides a safe and efficient way to power the system with your power sources connected via a pair of standard XT30 connections. The dual-power consumption system is designed to operate in balance mode, where it consumes the power line from either power source depending on which has the higher voltage. With a built-in black box module, the data (Power & Signal related) under unusual status during the flight can be recorded by TD receivers.
The configurable 12-channel ports are a big feature of TD SR12, each channel port can be assigned as PWM, SBUS, FBUS, or S.Port. With the FBUS protocol, the Tandem series receivers can open up the possibility of seamlessly pairing with multiple telemetry devices (Neuron ESC, Advance Sensors, etc.) as well as simplifying the builds setup.

💡Scratch built from plans. Plank on frame. Large brushless motor,150 amp esc,length is54 inches custom made propshaft ballraced at each end and middle. Has running lights,and large very bright searchlight. Flack Mats were made by better Half. Everything else was scratch built by myself.

Hope this posting works. It's a short video.

Too hot to go out today

Rotating beacon is R/C car accessory.

Radar is modified servo.

Water monitor is scratch built with cheap pump from ebay. Draws water from outside boat . Turns with servo.

Searchlight scratch built with ultra bright led.

Well this started off brushless but it had no soul or character, I bought an Os 40 fourstroke and converted it to be water cooled, I then made my own reverse gearbox and clutch assembly and fitted a water pump so the engine will keep cool while stationary. it has nav lights and a working searchlight that I can move while running.

Enjoyed making this superb kit from model slipway. Having to cut out the polystyrene sheets proved to be no problem. With 2 motors and bow thruster, thought it would be good for the steering competitions, but its a bit wide in the beam for our rather tight course. Working searchlight and rotating radar.

Here's a heavily modified Seaport Workboat - Toby. Videos to follow - the crane now works in three axis, and it has sound courtesy of a Technobots sound module. The searchlight works, as do the radar, running lights and nav lights.

Police (Scotland) 1.12 scale. made from a Semi-Kit by Models by Design, built 2014.
This is modelled from the interceptor42 range by Safehaven Marine. This is my first full build of a model, having only done restorations previously.
Model length is some 42 inch, beam of 12 inch. (106cm x 31cm)
Power is by twin E-Max BL2826 Brushless motors and 1, 80amp speed controller running on 2 NiMH 7.2 volts.
Fitted with Action electronics Police siren, and with detailed rotating blue lights and searchlights.
I sail this at Cold Knap Lake Barry Vale of Glamorgan, and I am the Founding member of the Vale Of Glamorgan Model Boat Club.
Also included is my Portland Pilot interceptor 42 which was the original prototype from Models by Design which I purchased and added lighting etc, this runs on Brushless motor running on 12Volt lead acid.

built this one after the first one was stolen which has turned out for the better. Has working fire monitors,anchor,bow thruster,sounds,searchlight,lightsand a bloke on the back having a wee, which in turn acts as a bilge pump to tell me there is water in the boat

Built from Aerokits kit originally but rebuilt/modified many times since then!
Twin 540's (geared) 6V Pb Gel battery for drive. 3 Blade 50mm props (contra rotating) lights (cabin, running Ights and searchlight) on 4.5V Deacs. radar scanner and winch on same supply, radar display screen on a single AA 1.5V.

Fleet Systems radio and speed controllers, Futaba rudders servo, RCME servo driving cam/micro switch unit for lights etc.
