billings Smit Rotterdam by pugwash1 Seaman   Posted: 1 month ago
Hi. This should help. https://www.youtube.com/watch?v=w7FOoRGlR68 It is a video made on board by a model maker. lots of detailed images on the net, I used Google search and had a trazillion hits!! Good luck with this one, I am completing the Billings kit, it is quite old and the wood used is quite poor, I recommend to anyone building her should replace the old wood cut out sheets. This was my first attempt at using a bow thruster, made it from some micro plumbing PVC pieces , waste brass and an old motor, it works great and I recommend it as a nice side project. Take care and have fun, should be great weather for a little Delaware pond fun!! see ya at the waters edge. Mark.

Circassia model boat by mbillany Apprentice   Posted: 2 months ago
Circassia- Glasgow Circassia was built in Glasgow in 1937 for Anchor lines Liverpool to Bombay regular route, carrying 285 passengers and 4000 tons of cargo. She was taken by the Admiralty at the beginning of World War 2 and used as a troop ship to North Africa. She never saw action but troops dubbed her the “ship from hell” as accommodation was limited carrying far more than she was designed for. She returned to her 13000 mile round trip India run after the war, making her last voyage in January 1966, after which she was sold and broken up in Spain. This model was a 2 year project by a local retired yacht builder who is a real craftsman, built from original drawings to scale with great detail. Original drawings included with the sale. Includes 3 new rechargeable 6 volt batteries, charger, twin screw and bow thrusters, all servos and all works including navigation lights too. The transmitter is a Hitec Laser 4 with 3 spare channels if required (never used). The model dimensions are LOA 5ft 4inches, beam 9 inches and stands tall from keel to top mast at 21 inches. She weighs just over 60 lbs and sits on 2 teak plinths for display and has a rather crude but effective launching trolley and lifting straps. The plans say it is 1/8th scale. Contact details are Mike Billany, ** email and personal phone nos. removed Please use pm to share this info** I live in Hedon, approximately 7 miles east of Hull. Strongly suggest visit to view and buyer will need to collect. Asking price for all as above is £600 or very nearest sensible offer please.

Damen Stan 4207 by RHBaker Fleet Admiral!   Posted: 5 months ago
Decided to advance LI-PO plans and try a 4S 4000mAh pack. This weight of this pack reduced overall model weight by 8 oz, so it is now 9.6 lbs, close to the original target. Was also to slide the pack further sternwards until it touched the inner face of the RIB slipway, about 2.5” from the stern. The effect on the waterline was limited; the model now sits slightly higher with the waterline remaining level. Slowly increased the speed of the motors to assess the LI-PO performance. There was a significant improvement. There is no need to use “ full” power as it probably exceeds max scale speed. As the model accelerates the bow lifts exposing an area of the red bottom paint. The wake streams down the side of the vessel and curls off the spray rails. She looks very realistic. The attached picture is at part speed. The model is totally controllable, the influence of the centre fins is noticeable as the heeling is not pronounced unless extreme manoeuvring is tried. After 90 minutes of use decided all original objectives for the model are now accomplished. She looks and performs well. The next task is to tidy up the temporary wiring and fit the LI-PO properly. Will also have to re-route more accessories through the voltage reducer fitted for the bow thruster so the LED lights are not overpowered. Have also bought a small r/c controlled child’s jet ski toy with the intention is using the drive and control system in the RIB. It will require much mutilation of both the jet ski and the RIB to work them in together, but think it can be achieved. My next blog will tell.

Victoria by Skipper44 Lieutenant   Posted: 6 months ago
[Score: 5/10] 39" Victoria Capable of 2mph and a runtime of 100mins Single Propellor (3 Blade 40mm) Belt to a Graupner 600 Speed (3 Blade) Powered by NiMH (7.2v) 4Amp/h Batteries Controlled Through Mtroniks viper Marine (15Amps) ESC - Comments: She is a 100cm long barge like ship, weighs too much to carry around easily so she doesn't see as much use as one may hope. She has a draught of around two inches and a bow thruster. This is complemented by a working anchor windlass and lights.

DAMEN STAN 4207 by RHBaker Fleet Admiral!   Posted: 6 months ago
First open water test went well, but with two caveats: 1) Would like to increase performance somewhat, closer to her looks. The initial tests of the unfinished hull showed adequate performance. As the detail and superstructure have been added, it has deteriorated. The increased weight of over 2 lbs has increased draft and wetted area, thus drag. 2) The bow is slightly low. Decided the best way to improve performance would be to increase the NiMh battery output from 7.2 to 9.6 volts. Thus added two more cells to the forward “C” cell holder. Also increased the LED resistor capacity and added a voltage reducer to avoid burning out the lights and bow thruster at this new voltage. By examining the drawings and the model layout decided to tackle the second by moving the forward battery carrier from just in front of, to just behind, the centre of gravity. Fortunately the Damen drawings show the C of G location. This increased the stern draught by about 1/4”, with the bow similarly decreased. Also reduced the stern ballast to about 3 oz. A further open water test showed an nice improvement in speed with the model now sitting on the waterline. Running time exceeds an hour, she also looks trim and purposeful. Think this is about as fast as an 9.6 NiMh installation will operate. Adding more cells will increase weight, adding to the draught. Am toying with trying a LI-PO installation in the future. This will provide increased voltage with a weight reduction, but rather costly though. Have decided to enjoy the model as she currently is; there is plenty to look at with the working fire hydrant, the bow thruster, the work and navigation lights. Will concentrate on launching and making the RIB operate, have some ideas on how to do this and will report in due course.

12 volt motors to esc,s by none Fleet Admiral!   Posted: 6 months ago
I have now just arrived two FR15 Series Microprocessor Speed Controllers. with BEC ? So I had in the past had a mixer and distribution board . But now decided just to omit the bow thruster and only wire in TWO motors.. @ 12 volts each.. So with 2 x 12 volt motors 1 x 12 volt lead sealed battery. 2 x esc,s 1 x reciver And a single rudder servo. and two y joiners for the servo. and the paperwork that came with the esc,s Being totally thick is there a drawing somewhere I can download So as to wire this in ? Also each esc has wires for a bec ? No idea where they go

Tamar lifeboat by Helineil Petty Officer   Posted: 8 months ago
I have recently started to build a model slipway tamar class lifeboat and when marking out the holes for the bow thruster I noticed that the lower spray rails were not symetrical and that the front 220mm of the port side needed building up gradually from 0 to 5mm and back to 0 in order to correct the problem. I only noticed this because I printed two bow thruster position patterns instead of using the one supplied in the booklet and when used together showed up the problem. Not to difficult to resolve, but hope this might be useful to other tammar builders. If anyone has any other hints or tips for making this boat I would be most grateful👍

Big Blue by Peter47 Commander   Posted: 8 months ago
Nice work so far, my Brother had a similar idea, re hatch sizes, but he scratched built boat hull in 4 watertight sections, held together with rods, pushed pushed down from deck and using computer leads for Bow thrusters/lighting/radar etc. With all sections in place it could a large tanker, remove one section it could convert to a coaster, using Bow and Stern it became a large tug, all superstructure could be placed in any position on deck,even bridge section could be altered, by sliding it back and forth, back for cargo /oiler, forward tug. All this he could do in minutes, so looked it looked like he'd brought a shed load of boats to the lake. :-)

Trawler "OUR LASS" by Dave M Fleet Admiral!   Posted: 9 months ago
Hi ginnyginny Graupner may no longer be available. Look at http://www.cornwallmodelboats.co.uk/acatalog/bow_thrusters.h... they have a selection of Raboesch. I also found the no e-bay. You could give Jackie a ring at Model Slipway to see what they recommend. If you Google model bow thrusters you may find more local suppliers. If there is noise it's probably because the internals have rusted. Hope you find what you want Dave
