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.

I bought this boat in reasonable condition five years ago from an estate sale. The original geared 540 brushed motors were rusted beyond repair, so I replaced them with a pair of 2830 1000kv brushless motors, running off a pair of 6 cell NiMH packs.
I use a transmitter mix to allow the model to rotate on the spot and perform scale-like docking manoeuvres.

Hello....Im after a bit of advice...Im trying to work on some rc subs and need 40mhz equiptment but I'm hitting problems getting recievers to work. I have a couple of 40 Meg hitec transmitters that work with 40 Meg hitec recievers in other models so I know they work. I have bought 3 different make recievers from different sellers and fm 40 mhz crystal sets and none seem to work...dual conversion or single makes no difference....Im running out of ideas has anyone got an answer to the problem?

This is a photo I found in a old album .It's my first R/C controlled model & I think it was a Billings tug The Sampson .The radio was a Cox Sanyo transmitter & Receiver . I had to get a C/B license back then to operate the radio . Years later I removed the deck & cabin & used the hull to make the North Rock tug boat . That's the speed control that I would have used back then.😊

A couple of members went for a morning sail I had may North Rock tug & a fellow member was checking out his latest R/C model that I really like the looks of her I forgot the ships name but the fellow running her said it was a Steam research vessel. I had upgraded North Rock to a Fly Sky transmitter & sure enough had to reprogram rudder & forward - reverse functions .

Had a little trouble getting my sound to work properly but with a little fiddling got it working a lot better had to reverse motor leads & switch transmitter forward -reverse switch so it would work in forward direction .

Today's weather was great for R/C model boat running & sailing in our favorite water hole the Hamilton Bay .The real Edward Cotter is a fireboat based in Buffalo New York & is also one of the oldest fireboats in the world . Near the end I almost had a disaster where I just touched the Ferry boat because I use a I-Phone to record videos & also run the models transmitter & some times I get distracted .

Finally had a chance to do a test on Pilot 40 project that was my lockdown stay home project . Change the props to 50 mill.4mill.threaded & now I have right prop & left prop Replaced the Sabertooth speed control as it was to hard to control with my Airtronics transmitter used a standard Hobby King speed control changed the wiring terminal block to a larger size as the one I first used was to hard to put wires in it . I always have trouble with mounting so glued the motors in with some goop & there just fine now

First time in the water for my 1/48 scratch built model of MV Overchurch Mersey Ferry. No extra ballast required and she responded well to the transmitter.

Finally managed to get this to come out the right way up on You Tube (didn't like MP4,- came out upside down). Running the 2 boats from an HK 6ch 2.4 radio (slight crash and jostling by the Maiami at the start) . You'll get sick of it in a few minutes and fall asleep but I've put it up anyhow😁 If this doesn't make you seasick, nothing will!😊 Hit a Koi carp (Chinese sub) at 3.01!

This ship was a lightship tender named "Coeur de Lion" that was armed and drafted into the Union during the civil war to counter blockade runners. This model is scratch built and is inspired by a paper model designed by Magnus Mörck. A sidewheel steamer equipped with the typical walking beam machinery, it was rebuilt to carry three guns. A line of iron plates along the gun wales added a measure of armoured protection. After the war it was returned to lightship service. On my model the paddles are independently driven, mainly because I have a Robbe Navy F14 transmitter with twin sticks. The walking beam is operated by a servo modified for continuous rotation. The original ship towed a barge that flew an observation balloon and could be described as the first 'aircraft carrier' the fifth picture shows the barge I have made - I hope one day to emulate the real thing by raising and lowering a suitable balloon. I have included some pictures of the rest of my paddle fleet.The 'Rachel Erin' is a freelance sternwheeler 'quarter wheeler' tug that uses a worm drive to the paddles. She does not steer well. The last ship is an enlarged version of Graham Goodchild's Santa Anna.

This yacht was purchased on a whim ? i spotted it for sail locally and thought it was about 30 inches high.
i had a shock on collection as its over 40 inches high and 3foot long.lt needed some attention to the electrics and transmitter and a lot of tlc. i think its big enough for my jack russell to curcumnavigate the world single footed !
