Vosper by Biscuit Sub-Lieutenant   Posted: 15 days ago
[Score: 10/10] 42" Vosper Single Propellor (3 Blade 50mm) Geared to a Os 40 fourstroke (3 Blade) - Comments: I always liked the sound of a fourstroke engine so I thought I would replace the brushless motor in this boat with an aircraft Os 40fs which I converted with a water cooling jacket that I turned up on my lathe. I also made a reverse gearbox with a clutch, the gearbox is operated by a servo and works well, I also fitted a water pump so could still cool the engine while ticking over stationary, boat has been weathered and is fitted with lights and a searchlight that swivels around operated by another servo, there is also a cooling fan above the engine just to help keep things cool.

BRAVE BORDERER - BRUSHLESS SUMMARY by Sakibian Chief Petty Officer   Posted: 16 days ago
Thank you! Found this pump in Ali express. Here's the link if anyone needs: Waterproof Ultra-quiet Water Pump 4.2W 240L/H Micro Brushless DC 12V Water Pump Car Submersible Fountain Aquarium Circulating https://s.click.aliexpress.com/e/cVs7aajO

Vosper by Biscuit Sub-Lieutenant   Posted: 16 days ago
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.

ASR 64ft R/C VID 2 by jbkiwi Lieutenant   Posted: 2 months ago
Boat is Scratch built 36" British Power Boat 64ft High Speed ASR Launch which belonged to the RNZAF. The launch was one of the 22 built and was shipped to NZ in 1940. It was the only one of its type in the Southern Hemisphere. Model has twin motors, ESCs, sound units etc. Has remotely switched water pump for water cooled brushless 2000kv in runner motors and remotely switched lighting. Uses 2x 2200mah 2s LiPos for drive and 1 1800mah LiPo for the pump (also a separate battery for the LED lights. Boat is built with strip planked balsa on ply frame and fiber glassed. Deck is ply, wheelhouse is varnished balsa. The colour is as it was for most of its time in the RNZAF . Took about 5 years on and off to build and finished it last year. (please ignore the time date - can't get rid of it .

Clyde Puffer by lesliebreame Admiral   Posted: 2 months ago
At Illfracombe pond last week . Have made an automatic feed water system for my coal fired Puffer and went to the pond to try it out. I think it needs bigger capacity pump as there was very little water in the boiler after 3/4 hour running. Gordons hydro is beating me up as usual !!! Les Breame

Clyde Puffer by figtree7nts Fleet Admiral!   Posted: 4 months ago
Nice idea, water pump filling the boiler. Can't wait to see it in action!

Clyde Puffer by lesliebreame Admiral   Posted: 4 months ago
Clyde Puffer project showing new water filling pump and electronic level control as yet untested !! Fingers crossed !!

R.N.L.I. Concept Tug by Fred Commander   Posted: 5 months ago
[Score: 5/10] 24"/900g R.N.L.I. Concept Tug Capable of 1mph and a runtime of 60mins Single Propellor (4 Blade 35mm) Direct Drive to a 540 (4 Blade) Powered by NiCad (7.2v) 8Amp/h Batteries Controlled Through ESC from Chiner (10Amps) ESC - Comments: This started out as a Seaport Dickie Harbour Tug, that came with a 40Mhz radio system, ESC and a small water pump. So the first thing was to remove the 40Mhz system and replace it with a new 2.4 alone with a replacement ESC, I also removed the water pump. It was now time to think how I was going to repaint her, as the club had been invited to out local R.N.L.I. station I came to the decision that I would make her into a R.N.L.I Concept Tug.

Smoker / Light Contoller by timgarrod Sub-Lieutenant   Posted: 5 months ago
Afternoon All, Really please as finished off the smoker/light controller i've been working on. it works with any smoker that has a fan. theres three version avaible, but all versions have the same light functions, one switch - on /off (can change to a proportional to work with a water pump) Three position Swich, controlls two light circuts or anything. Oil heater, will turn the fan and heater on only when required. saves on Battery and to replicate a diessel engine. Water vapor system, able to turn off/on the power to the system remotely, Diesel engine, will power the fan 100% and the start and the slow the fan down till model is just about to move off. Steam Engine - Fan at idle is about 20% so always push the smoke up but then it will encrease with throttle input. the best thing i think is that any thing can be changed via the arduino. Will be make a few so if any one interest in one, please PM me. this is one i've just made for a friend that use the Oil heater https://www.youtube.com/watch?v=JDLp5bACejc&feature=youtu.be and mine using the water vapor systemhttps://www.youtube.com/watch?v=pj2pICSLHcE Thanks

Controls problem by malcolmstroud Petty Officer   Posted: 6 months ago
Thank you for your replies! Low battery is not impossible; but it powers the motors fine direct, receiver lights come on, ESC lights come on, and the phone connects to the receiver fine via WiFi, so I assume it's OK. Peter - I will pop along to Bury, probably today, as it's a lovely Sunday morning. Thank you. RNinMunich - I don't have a compatible TX but will look into that at some point. I did consider the 1:350 version, but read that the dies were very old now, and that the Academy 1:400 was more recent and far more accurate. I'll show some pictures of the hull layout later. It was quite a struggle, and I've gone to quite a bit of effort to keep it balanced, with a heavy water pump towards the front to make it go 'down by the bow' (but not sink). Yes, quite ambitious. The hardest part was that the two outer props are incredibly close to the hull, so that only very small motors will fit. I didn't want to go for any sort of flexible coupling as I thought that would lose too much power, and larger motors probably wouldn't fit anyway. I don't really mind if it's slow and hard to manoevre, as that would be realistic. If it doesn't work I may rip the motors out and just pit one big one in the middle and steer by rudder.

H.M.S. BRAVE BORDERER by RHBaker Fleet Admiral!   Posted: 7 months ago
From the brief pool test, had decided that the motors could be susceptible to overheating, so connected up the water jacket cooling system and powered it with a small pump. Did not leave enough space to fit a scoop behind a propeller anyway, but prefer the positive action of a pump though. From feeling the ESCs, was also concerned they could overheat within a confined space such as the hull. Mounted a couple of small fans in a bridge structure above the ESCs, along with the ESC switches. Not sure either of these cooling modifications are really required, but erred on the side of caution. Final weight of the hull, with all electrics (apart from battery) comes to 5.05 lbs. Looks like will not achieve the target weight of 6 lbs, but am hopeful will be able to get close to it.. Built the deck up with gun mount bases and a removable decking over the engine area. This limits access to the internals; so will not fit it permanently until the test program is complete and all modifications incorporated. Have now reached a point where any further work will be to start finishing the model, unless drivetrain modifications are required. Have thus decided to leave it until after the first open water test date. This will be in late May as am away until then.

H.M.S. BRAVE BORDERER by RHBaker Fleet Admiral!   Posted: 7 months ago
Once the rudder, propeller and shafts were installed, the position of the motors could be established. A light aluminium bracket to hold all three was fabricated and bonded to the hull. Due to the high speed capability of the brushless motors, particular attention was paid to alignment. Also kept to the shortest prop. shafts that could be fitted to avoid whipping. Although the motor type might change, whatever is best will require a sound electrical installation as the current requirements for each brushless motor could reach 50 Amps. Wired each motor and ESC separately with its own dedicated fuse to give the maximum system protection. There is an extra fuse section allocated for auxiliary circuits, such as a cooling water pump and lights. Will try the original planned layout of 3 x 2835 motors with 30mm propellers and a 2S Li-Po battery first. Am hoping the reduced voltage will also make these motors more tractable. For the test program the three ESCs will be each controlled from an individual Rx channel. Once the final layout is determined, a more sophisticated and flexible control system can be installed. To minimize ballast, particularly around the stern, the battery will be housed as far into the bow as possible. After the test runs the final battery type, size and location can be established. To assess performance, hope to try both 2 and 3S Li-Po batteries. Planning to reduce heat build up by fitting cooling water jackets to the motors, these are easiest to instal at this stage so the wiring or mounts are not disturbed in the future. Have not decided the layout for the water circuit yet, but this easily can be added later. All that is needed now is the ice to melt off our local lakes so tests can commence.

Grimmershorn II by CB90 Fleet Admiral!   Posted: 8 months ago
[Score: 5/10] 40"/5000g Grimmershorn II Capable of 7mph and a runtime of 60mins Single Propellor (3 Blade 70mm) Direct Drive to a 950 (3 Blade) Powered by Lead Acid (12v) 12Amp/h Batteries Controlled Through 15A 24v (5Amps) ESC - Comments: The Motor vessel 'Grimmershorn' was built in 1956/57 by Hansa Stahlund Schiffbau GmbH at Koln-Deutz for the Waterways and Shipping Administration at Cuxhaven.Her Daimler-Benz four stroke diesel engine had an output of 500hp. permitting a speed of 11.5 knots. The model hull and deck are vacuum formed ABS, timber work of precision cut ply, 2 full size plan sheets and a construction manual along with a fittings pack complete this kit. Technical Data Scale: 1:20 Length: 1038mm Beam 305mm The Grimmershorn was the second major kit I purchased from a model shop on the outskirts of Harlow in Essex back in the 1980s. The Krik kit is still produced and sold today. My build was a slow and lost enthusiasm so after completing the hull, deck, motor and bow thruster installation I gave the boat to my father in-law who completed the superstructure and sailed the boat for a while, eventually the boat was given back to me when the father in-law moved house. I then repaired the rudder, added a moving radar, a adjustable water cannon and pump also various extra fittings such as a detailed life raft and crane, buoys and captain figure. thus renamed the boat as Grimmershorn II a Search and rescue fire boat.

Sanding down. by MouldBuilder Captain   Posted: 8 months ago
Thanks Kevin. A model shop just gave me a good tip. Buy a car screen washer pump for the water cannon on my new project Police boat. They said it would be cheaper than the model pump. Halfords next place to visit. Glad I could be of help Doug. I have bought the 50cal. guns to match the carriages. The assembly instructions are available on the site. Still worried about breaking them whilst removing them from the sprue.🤔I am a precision engineer but this still fills me with nerves.😱

Caldercraft 6-12v Water Pump by bilzin Commander   Posted: 9 months ago
Almost finished me WSPS47 now and find that I have the fire monitor pump here STR at this time. This item is totally unused and still in the sealed packing it arrived in. I have checked the (surprising) cost of this pump online and I am asking nowhere the advertised price, in fact, if anyone would like to purchase it or has any swaps I'd be glad to hear from them 73 de Bill
