Hi Gordon, "the boat is to be a present for my son. He works abroad for long periods and I reckon a lead acid would go flat beyond recovery." In that case an SLA (especially the types produced to power alarm and emergency lighting systems) would be your best bet. They can be left on trickle charge indefinitely. Two 6V in series might be better than one 12V to help with trimming out the boat. I use a pair of 6V 3Ah (about 600gm each) in my 135cm destroyer and 107cm submarine. They run for hours if I don't keep the pedal to the metal all the time. 😉 Back home I stick 'em on the trickle charger and leave 'em until the next outing. They've lasted my several years so far. Much longer than my NiMhs. An NiMh looses approx 1% of it's charge per day. So, assuming it starts fully charged, in 3 months or less it would be in Deep Discharge and have joined the Dodos😭 Cheers, Doug 😎
Hi Doug I’m using 2 x12v SLA wired through an action electronics parallel board to give 12v. I hope to feed the power through the existing action electronics fused power distribution board which will feed the two esc and all my on board lighting, radar scanner etc. Cheers Selwyn

The 70-year US Coast Guard semi-deck. All-metal construction, 2 x MIG 480 motor, standard servo, model illuminated on two circuits. One light mast, position lights and cabin. The second lighting circuit in the hull of the ship and the outdoor lighting around the superstructure. There are no labels on the model yet, I'm waiting for the fabrication. Battery 1 x LiPol 4000 mA. The total construction took me half a year. I made the hull made of laminate from my friend in Slovakia. The superstructures themselves are made of laminated boards. Part of the light bulbs are 6V lamps and the strobe with positional lights are the LEDs of the light triggering through two RC switches.😉

Hello, Doug! I’m happy to report that my eyes are finally healed & I’m ready to get cracking on my tug’s LED lighting improvement project. Needless to say it’s so fantastic to be able to see again. The infection was so bad that I had to move around the house for weeks with at least one hand on the wall or I was in danger of falling or walking into the china cabinet. I lost what’s called “stereo vision” & had no depth perception. It was a nightmare to say the least, especially considering that the source of the infection remains unknown. But I just had a checkup at the ophthalmologist‘s office & I was given the happy news that all traces of the infection are completely gone. Hallelujah!🙏🏼👁👁 BTW, did you complete your tug’s mast LED lighting project? I recall that you had finished up the mast itself & had its LEDs working. Were you able to reinstall the mast in the pilot house roof & get everything back together without any problems? At one point you had mentioned possibly making a plug & socket arrangement for the mast so that it could be removed for safer transport to the lake. Were you able to follow through with that plan or was it just is easy to simply re-install the mast? finished for your dog? If so, how did it come out? I hope all is well with you & that your many projects are all turning out successfully.
Hi peter, 'Deck Blue' changed a few times over the years, there are lighter and darker shades depending on the theatre of operations and if detection from the air was paramount or not. Later in the war, when the axis air forces were largely destroyed and the allies had overwhelming air superiority the emphasis moved to the vertical surfaces to confuse subs and the few remaining surface ships the axis had. Then the emphasis switched back to the horizontal surfaces when the Kamikaze attacks developed. So probably the lighter Pacific variant is what you need for USS Kid at the end of the war. You are lucky that Kidd has been preserved as a museum ship in her 'end of war' state 👍 If you Google USS Kidd I'm sure you'll find the museum site with more colour pics. Also, the display on different web sites will depend on many variables, for instance:- How the sample was photographed; white balance, colour balance, lighting; intensity and type - Kelvin temperature etc. How the photos are digitally interpreted and integrated in the web site. The times of 'The camera never lies' are unfortunately long over! Added to that is how your PC or Dumbphone/tablet displays the web site, similar problems;- Type of display, colour / contrast / brilliance settings etc etc. Power saving settings can affect these! If I were you I would use the Measure 22 scheme as shown on the colour pic and described on the Wiki page. That's apparently what the USN went back to when the kamikaze attacks started. Your basic choice is enamel = Colour Coats, or Acrylic = LifeColor 😉 Personally, I would go for the 1944 dazzle scheme cos it's more interesting and unusual, but then I'm just NUTS! 😁 Cheers, Doug 😎 PS Hofbrauhaus is for the tourists! I've been there maybe three times in 38 years? Once on my very first visit to Munich in 1980, then, after I started working here in 1985, only with customers who insisted on going there. Too loud and expensive, there are many better, less touristic, ones in Munich. Prost allseits! PPS haven't been to the Oktoberfest for years for similar reasons! 30 years ago it was still fun, but not now 🤔
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 .
[Score: 8/10] 33"/3700g "Maureen Lee" Capable of 3mph and a runtime of 90mins Single Propellor (3 Blade 30mm) Direct Drive to a 550 type (3 Blade) Powered by NiMH (7.2v) 3Amp/h Batteries Controlled Through Unknown ESC - Comments: The “Maureen Lee” started out as a Bristol Bay ready-to-run semi-scale model of a typical European fishing cutter. Many modifications were made to her to make her look like an old, worn-out fishing boat. Factory-installed switchable work and navigation lighting means that she can even be operated at night. A 550-size electric motor and metal propeller allow for ample power. A Bristol Bay model is supplied practically fully assembled… you need only mount the two masts and install the batteries. Numerous robust details make this model look great at home or on the water! Technical specifications: Hull length: 850 mm Width: 220 mm Overall height: 737 mm Total weight: 3650 g
Shucks! An I was hopin' you'd build me a little 4 cylinder diesel for me to run a brushed motor as a Genny for all the lighting on my ships! Or for the diesel electric propulsion on my Type 45. Now wouldn't that be cool!?😁 BTW Some of Nick Carters tips an tricks showed me how to convert one of my tools to something that'll do what I want! So, out with the Proxxon mini-grinder😉 Cheers, Doug PS It wasn't a wrong steer cos it led me to all sorts of useful 'stuff' and above all helpful info👍
This is my scratch built 36" RNZAF British Power Boat 64' HSL (arrived in NZ 1940). I actually went on board this vessel in 1968 when it was still in original form (the RNZAF having disposed of it in the 50s) This vessel is still around and has been recently re modelled (2nd time since early 70s) and I was lucky last year to have met the present owner and go on board (2nd time in 49yrs!)and take a few photos. The vessel was modified a number of times by the RNZAF over the years (air intakes, removal of the fore deck machine guns, wheelhouse turret etc so I sort of went in the middle. I found a few drawings of the type in an old mag which had side and top views plus the bulkheads and their positions, so I took them along to a copying shop and kept enlarging them until I had the desired proportions. This worked out quite well and using a few methods from other models I had built, managed to frame (ply) the hull and then fully strip plank it in balsa. It was then fiber glassed. The deck is ply, lined and varnish stained. The wheelhouse is varnished balsa and is removable for access (wheelhouse roof is also removable along with engine cover and foredeck access hatch, - small foredeck hatches open as well.). The wheelhouse interior has detail such as controls, instrument panels, skipper, steps to wardroom etc but is not too detailed as it is not seen. The boat has full lighting by remote switch, lights are all LED. All cowls rotate. The propulsion side has dual everything (motors, ESCs, sound units), would have had 3x but ran out of space! Motors are 28mm 2200Kv water jacketed in-runners (cooled by remotely switched pump) using 30A Chinese ESCs (have 5A BEC, Fwd and Rev). Twin sound units are 'GT Power' car units which have around 40 different sound selections, from Cosworths to diesels and are computer programmable (as well as manually on the unit ) for various functions. I am using one of the v8 sounds (8 cyls short in my application) which I think is as near as you are going to get to 3 Napier Sea Lions (for which there is obviously no sound available) They 'start' 'Idle' and are fully proportional in fwd and rev and can sound quite realistic (will attempt to put up a vid later). Batteries are 2x 2200mah 2s 20c LiPos which will last around 2hrs at least of sailing (they also run the sound units) Still have a few small things left to do (have just made wheelhouse air intakes) but don't want to get too fiddly. Just want to keep it a practical model.
Mornin' Pete (it is in Germany anyway!) I agree, there are lots of details and 'standard equipment' missing from the basic model. You can see the winch and Life Raft canister in one of the photos of the original I posted above. Re Mast wiring; don't fiddle about putting a divider in the mast. It'll just get in the way. Attached is a pic of my modified mast. I used a 0.5mm brass wire on the right-hand side for the earth return. Wire is better than rod cos it's flexible (can be pushed into the corner). I glued it in with gel Gluper Sue WHEN all connections were soldered and tested. The LEDs are standard domed lens types. I ground the tops flat and painted the tops with several coats of matt black until it was opaque. After testing I closed off the mast with some plasticard and fitted ladder rungs made of copper wire. I also added the missing antenna cables to the bottom of the VHF IMM antennas, 0.5mm brass wire. (Some time I'll also fit the missing GPS antenna and anemometer.) Then painted the mast matt black. I then turned my attention to the searchlight and red/green NAV lights. First I stripped the wheelhouse roof and painted it white as in the original. On my model it was grey🤔 Then I drilled out the searchlight to accept a 5mm Bright White LED. You won't have to do this cos you have a later version with lights, mine had none 😭 Then had to paint the searchlight with several coats of matt black. Otherwise it just glowed all round! Pics show construction stages and finished lighting effect. All wires inside the wheelhouse roof I super glued to the ceiling and ran them down inside the funnels (stacks to you guys across the pond!😉) ready for connection to a switch board in the hull. While I was at it I rubbed the false Southampton name off the cabin using a 1000 grit Tamiya sponge and am preparing inkjet printed decals with the correct Wyeforce name and logo. Have fun getting all lit up Pete,😁 Cheers, Doug 😎 PS Attached some pics showing the original 'Southampton' 😉 and making obvious what's missing on the model 🤔
OK, found some! https://www.ebay.com/itm/8pcs-JUGEE-3000mWh-1-5V-rechargeabl... Interesting that they all quote mWh instead of mAh! I.e. energy instead of capacity! Power being V x I (Amps) divide the mWh rating by the nominal voltage to get an approximation of the capacity in mAh. Saves integrating across the varying voltage during a discharge cycle, i.e.'On Load' 😉 Thus these 3000mWh cells seem to have a capacity of around 1800mAh. Which is considerably less than the typical 2500mAh of an alkaline or NiMh AA cell. Also, to produce the output voltage of 1.5V from 3.7V Lithium chemistry the cells have an internal voltage regulator, which also must consume some power, albeit miniscule. Something else which can go wrong🤔 Summary; yer pays yer money and takes yer choice! Seem rather expensive to me for what they deliver. Depends what you want to use them for. Might be useful in my Sony camera but I wouldn't use them for any high current load in a model. OK perhaps for LED lighting circuits which only need a few tens of mA. Here a list of battery types, sizes and chemistries for reference. https://www.wikiwand.com/en/List_of_battery_sizes#/overview Cheers, Doug 😎
