March'71 by Sakibian Sub-Lieutenant   Posted: 7 days ago
[Score: 8/10] 18"/500g March'71 Capable of 9mph and a runtime of 10mins Twin Propellors (3 Blade 25mm) Direct Drive to a 180 brushed motor (3 Blade) Powered by LiPoly (11.1v) 1Amp/h Batteries Controlled Through Hnadmade by arduino (30Amps) ESC - Comments: The BEST thing about this one is, she's very smooth on the run. Decent power, makes it more fun. When it turns with speed, gets down like a bike. So that's the time when it leaks a tiny amount of water. Bcz it's not waterproof on the deck. Can take 2s-3s Lipo. Bcz the motors are 3s rated only. Have a plan to change them into better Mabuchi ones.

Propshaft Lubrication by canabus Fleet Admiral!   Posted: 19 days ago
Hi All I use silicon tap grease as it's waterproof and add a bit more after each outing. Strip down, check for wear once a year and regrease. Started using Teflon bearings for the lower bearing which are holding up to the brushless motors. Canabus

All hooked up, nowt happens... by DodgyGeezer Lieutenant   Posted: 22 days ago
This 'Cheap Chinese' design, according to the documentation, seems to come in several different (nominal) amp ratings, and, interestingly, in a 'standard car' or in a 'crawler' version. The one for crawlers - slow rock-climbing cars - is also recommended for tanks, and has a jumper giving the sort of instant reverse we would use for boats. This looks like an example... https://www.ebay.co.uk/itm/Waterproof-Brushed-1060-60A-ESC-F... Which might help if anyone's browsing cheap brandless ESCs...

All hooked up, nowt happens... by canabus Fleet Admiral!   Posted: 23 days ago
Hi All If you require a brush ESC. The Hobbyking one is the only one I have found with straight forward/ reverse with NO BRAKE. Set is with links, but the they only work on Nicads and Lipo batteries. They will run on 12 volt SLA, but no less!!!! I am using them in my two Hellen fishing boats with 55 turn rock crawler motors on 2S Lipo on 60% throttle. https://hobbyking.com/en_us/hobbywing-quicrun-60a-2s-3s- style='background-color:yellow;'>waterproof-brushed-esc-for-1-10.html Canabus

Pretend deck planking by RNinMunich Fleet Admiral!   Posted: 1 month ago
Hi Steve, What went wrong? 😲 1. Drawing on deck planking, i.e. on a veneer or thin ply- Why/how did it go wrong? Surely since the planks are all 'parallel curves' all you need to do is make a curve template in plasticard from the plan. Then at a few strategic points along the plank length mark the widths of the planks. Set the template along these points and 'Bob's yer Uncle - Fanny's yer Aunt' 😉 Mind you; doing it that way the 'curious grain of the planks' would betray the fiddle🤔 2. 'what type of strip wood - Any very close grained type. Possible source- http://www.slecuk.com/index.html 3. How to glue it!? Any thin, spreadable waterproof wood glue! 4. Gap? Max 0.5mm perhaps. Ca 10 to 1 ratio. 5. 'How do you secure the bent planks whilst the glue dries? Modelling pins at strategic points along the plank. Assumes planks are pre-shaped by steaming!! See 6. 😉 6. 'Do I need to steam the planks? - YES! As mentioned above; make a template defining the curve required. From this make a jig of ca 5mm x 10mm in which you can set the steamed planks to cool and set to the shape required. To allow for the so called 'spring back' make the jig with a slightly sharper curve than the actual deck curve. When fitting the planks to the deck it's easier to 'push them out' than to try to increase the curvature. Finally; mark on the deck base the plank widths at strategic points along the plank length as alignment points. Glue planks alternately left/right (OK port/starboard😉) using modelling pins to hold in place until the glue is fully cured. For the 'gaps' There are various solutions in Build Blogs on this site. One that I like is the use of thin black card. When the whole deck is planked and properly cured sand lightly (ca 240 grit). 7. 'weathered teak' there are various suppliers of teak stain and also deck weathering stains; e.g. Jotika stain, Lifecolor Washes for Hulls and Wooden Decks, set part no. LP04, which includes Wooden deck darkener and Shadower, amongst other useful weathering pigments. http://www.astromodel.it Google Lifecolor and you'll surely find some UK distributors. Enough answers for enough questions!? 😁 Hope this provides some inspiration, Cheers, Doug 😎

Proboat Sonicwake by boaty Admiral   Posted: 2 months ago
Three weeks ago I got a Proboat Sonicwake deep V fast electric. This appears to be a replacement for their previous model Vorocity. Very interesting self righting method with a water tank on the port side, slots in the deck and a large exit point at the stern. Idea is that if it capsizes, water will enter through the slots and as it draws the boat under, the air trapped in the hull will self right it. If the boat is stationary in the water, it will list to port due to water entering through the stern outlet and when power is applied it will empty out. Bit scary to watch at first as I thought the boat was on its way to Davy Jones. I use waterproof marine clear tape to seal around the hatch ever time I use it. The quality of the hull raises a few concerns. This relates to its ABS construction as the vast majority of similar boats at that price are made of fibreglass which is much more rigid and would be more suitable for the high speeds. Makers claim it does 50 MPH plus on 6S lipos. The electrics however are excellent with the exception of the external quality of the Horizon Hobby STX2 TX which looks a bit "toyish". For myself, this is not relevant as I replace all my wheel TXs with the "stick type" and I found that the Futaba T2HR fulfils all requirements and worked well when I sailed the boat. I have not yet changed the stock prop for an Octura one, the latter works great on my Blackjack 29 with a noticeable increase in performance. The motor is a Dynamite Marine W.C brushless 1900 KV with a 120 amp W.C ESC . 😁😋 Boaty.

I had a look at my suppliers, and found this in Amazon(!). Any good? "DIGITEN waterproof In Line standard Blade Fuse Holder fuses+10A 10Amp kit car boat bike". Good luck with your testing!

Transfers by RNinMunich Fleet Admiral!   Posted: 3 months ago
Hmmmm!! Waterproof? Have you ever tested that? I'm not so sure, having used them in the office virtually since their inception. Anyway, when they are mounted on the boat / ship they need sealing in with a coat of clear lacquer or they may sometime 'float' off again. Apart from that have not yet seen any transfer paper made for Laser printers. Transfer paper made for Ink jet printers may melt 😲 in laser printers in the final transfer / fixing unit. I can tell you, it makes an 'orrible sticky mess wot ain't easy to get rid of. Doug

Transfers by Haverlock Fleet Admiral!   Posted: 3 months ago
its even better if you can get a hold of a laser printer since the "ink" is waterproof so no need to varnish before doing the waterslide.

Carry case. by DodgyGeezer Lieutenant   Posted: 3 months ago
"It's not very heavy and it won't get wet!" Unless you never put it down on wet grass, and drain and then towel your boats after use before putting them back, it will. Be sure to get all the water out of the prop-tube.... " I can't be arsed with fancy carpentry. " No carpentry involved. The material is like cardboard, and you just cut it out with a Stanley knife and fold it. Takes between 10 and 30 mins to make a box from scratch... " And what IS Correx? " Sometimes known as 'twin-flute', it's the stuff estates agent's boards are made of, amongst a myriad of other uses. A twin-walled polypropylene rather like a kind of cardboard made of plastic. Very tough, feather-light and impact-resistant. Self-coloured (many colours available) and completely waterproof. Needs no framing - the sides are strong enough on their own... See the link for full description, place to get it and plans...

Cleaning sails, toy yachts, etc.... by Westquay Fleet Admiral!   Posted: 3 months ago
My wee red boat after a rub down and a file/sand on the steel keel. This morning I painted the red with HMG enamel and got the green mixed in the same make enamel by my wonderful chap at Kett's Auto Paints. The mast came in two parts, so I did a slight scarf and glued it. When the joint is well set, I'll make a splint and set it in prior to a rub down and a good waxing. The steel (tinplate) parts came with the predictable rust, but with my selection of scrapers and chisels made of broken and worn Swiss files I was able to scrape most of it off back to reasonable shiny steel. The out of shapeness needed only a clout with a cold chisel type of bodywork tool in the right places to restore it to original shape. Loops were filed to lose most of their rust, but not replaced. They'll be Vaselined as a form of anti rust, waterproofing. I have some new 1.3mm cord coming from Caldercraft. I just hope I can remember how it was rigged. I ain't great with knots. The sails were absolutely filthy with some sort of oil based grime, but my dear bride sorted them out with Vanish and a good hand wash. Pics of those tomorrow. I love this stuff.! Martin

Cygnus GM32 by canabus Fleet Admiral!   Posted: 3 months ago
Hi Cygnus GM32 I am using these Hobbyking ones https://hobbyking.com/en_us/hobbywing-quicrun-60a-2s-3s- style='background-color:yellow;'>waterproof-brushed-esc-for-1-10.html Links to setup the ESC on Lipo and Niamh. I have used them on 12 volts , but, they will not work on 6 volts. You can crash straight from forward into reverse !!! Running a 70mm 3blade on one Hellen fishing boat (weight 14 pounds) and a 60mm brass 3 blade on the other Hellen.

BRAVE BORDERER by jbkiwi Commander   Posted: 4 months ago
Good to hear you are making progress with the noise. My ESCs are not programmable as far as I know (There may be a card somewhere). They were cheap Chinese waterproof car/Buggy ESCs with Fwd and Rev which I wanted for independent drives but for the price and how well they work, you can't beat them (about NZ $20 each) They have a very soft start (you can count the revs) programmed in as std, and the only problem I have found is that they sometimes won't go straight into reverse without quickly nudging forward and back, (just need to drive in a scale manner and it's fine.) I'll put a pic of the unit and motor in (also a brushed one I am using in the MTB (x2) which work perfectly only NZ $9.00) They have braking, FWD, FWD+REV and batt type adjustable by jumpers. Throttle set-up is simple with full FWD and partial Rev set by the sticks. Both types are 30A and never even get warm. I purchased some fans for them but have never used them. The brushless units have a fan plug on them. The squealing I have may just require a switching frequency change on the ESC (8kHz/16kHz -more RF noise on 16kHz but more efficient) but I don't think I have that option (do you have that option to try on your set-up ? might be worth a crack). The sound units muffle it a bit anyhow. Boat runs at 10mph (GPS) flat out (looks way off scale) but only needs about 1/4 - 3/4 throttle for normal cruising. Will try to put up an external vid soon. Transmitter is easily modded to twin throttles,- excellent cheap set for boats ( later model has internal aerial)

Added ESC by CB90 Fleet Admiral!   Posted: 5 months ago
Added a 60A ESC of Chinese origin, improved waterproofing, and modified the rudder water pickup. Repainted trim tab extension as while it sat in the test tank (AKA the bath) the water got into the wood and split the paint work car spray paint not as water proof as I had hoped. On the test I found it was pulling over 40Amps which is not what I want as this is a race boat with limited battery capacity so cut down propeller by filling of the lagging edge of the prop via a drimmel and a file, so now pulls under 30A at full throttle. At the pond I will check current and prop-sizes.
