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.

Was asked for more info . So here are a few photos . This mini humidifier uses water only to generate fake smoke no smelly baby oil & varsol odor 50%-50% mix for Graupner smokers .I get the power to run unit from the receiver battery port as the unit uses a USD port to make it work so I got a old servo & cut the wire off it removed the signal white wire & used the black & red wires to power up unit . I have to turn model on then power up the Humidifier to start fake smoke put the cabin on model & away we go. Make sure Positive & Negative are put in proper receiver slots Please don't damage receiver if it's plugged in wrong.

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.😊

I recall getting GRS licences for two "CB" mobile radios & a base station in the mid-70s, & also a licence for a 72 MHz $400 Cox-Airtronics 4-function radio system for 100"-span Standard-class gliders, using only rudder & elevator servos. I believe the licences were $19 /yr each back then.
In abt 1990 INDUSTRY CANADA narrow-banded the RC channels & therefore was able to add a few more channels. The service category also became licence-exempt, but type-approved radio apparatus, certified for use in Canada, was still a legal requirement.
By then CB radios were 40ch

After a little video of the H.Sw.Visby I tested out my no name R/C boat over the winter change motor coulping & receiver . So she need a little test run at the Hamilton Bay Leander dock seemed o/k to me so looking forward to a summer of model boat sailing . The kids must have been off due to Earth Day & here in Canada Covid restriction have been mostly over .Thank goodness .

At first I was surprised to see you with boats on open water in Canada.
This week we finally have open water in Central MN, but it was just on the news that there is still 18" of ice on the lakes in northern MN.
THEN, I looked at a map and realized that you are considerably south of me. Basically as far south as the MN Iowa border.
OK, I'm jealous! I want to be able to play on the lake with my toy boats too!

Building a German Police launch right now and thought that the radar scanner components were a bit 'heath robinsonish', so decided to see if I could make an alternative unit.
Photo 1 shows the Radar scanner parts obtained from MMB (ebay) for the princely sum of ONE POUND !!!!! plus 28p postage, and construction is of a medium soft resin that isn't prone to breaking or splitting when shaped or drilled, and a short length of 2mm brass rod becomes the drive shaft. This particular unit has a 44mm sweep bar but there are many other sizes available
Photo 2 shows the drive motor which operates on voltages between 1.5 and 6v, ideal for the control driver which is the next item. Available from saih.tan on Ebay for under 7 pounds, and if the motor is mounted on a removable bracket as I have done, this unit can be used in several models without the need for major 'surgery', the motor and radar shaft being connected with a short piece of rubber tubing
Photo 3 shows the receiver driven radar motor speed control which operates from an auxiliary receiver channel and takes the motor voltage from the main receiver supply, thus obviating the need for a separate supply and switch.
This unit is available from www.mr-rcworld.co.uk and costs a staggering 14.50 post free sheesh !
I must add here that I am in NO way connected to any of the suppliers mentioned here, but just though some other modellers may be interested in 'home brew' accessories and suchlike.

This Aerokits "Sea Commander" was built C.1961 by my father with ED Mk4 diesel engine and his own scratch designed and built radio/receiver ( I have all his design documents). He raced it successfully in the early '60s but hadn't used it in years when I inherited it. Have now replaced the IC motor (mothballed carefully) with MFA Torpedo 500 but it runs a bit slowly ("river cruising" scale speed). Looking to obtain semi-planing but not racing speed.

Looking to obtain semi-planing but not racing speed.","subject":"Jaydee","media":[{"id":"1492343939","name":"1492343939.jpg","caption":"","url":"https://hobby.land/media/1492343939/l","thumbUrl":"https://hobby.land/media/1492343939/s","isImage":true,"ext":"jpg"},{"id":"1492344249","name":"1492344249.jpg","caption":"","url":"https://hobby.land/media/1492344249/l","thumbUrl":"https://hobby.land/media/1492344249/s","isImage":true,"ext":"jpg"}],"youtubeUrl":""}
This Aerokits "Sea Commander" was built C.1961 by my father with ED Mk4 diesel engine and his own scratch designed and built radio/receiver ( I have all his design documents). He raced it successfully in the early '60s but hadn't used it in years when I inherited it. Have now replaced the IC motor (mothballed carefully) with MFA Torpedo 500 but it runs a bit slowly ("river cruising" scale speed). Looking to obtain semi-planing but not racing speed.
Thanks Johnlikessailing. However, I have now replaced MFA 500 with Mtroniks 600 and got much better performance, although I'm not sure how much of this was due to the change of motor and how much was due to rectifying the slippage due to a loose grub-screw on the connection between the motor drive shaft and the universal joint that I found when I removed it! (Lesson - beware of alternative causes of problems!) Now I just need to sort out a leak - hardly a surprise on a 50 yr old model! Hey-ho!

Built this Wave Princess 30 years ago meaning to use it with my children. Languished in attic since and now retired going to resurrect her for Grandchildren and would welcome any advice on motor size, prop shaft length, Propeller size etc etc. Picked up an as new MacGregor Digimac 111 transmitter receiver and servos at Boot Sale for £5, seems fitting I should use it for the old girl.

Hi Good to see an ex ic model converted to electric power. Have you any on water shots? We have several air boats in our club, good for when the weed is a problem,
