Trying to learn to use this forum properly I am publishing a video that shows an experiment I did to find out how fast the stepper motor could turn. I am using in my model of the sailboat Carina 2 stepper motors like the one shown in the video to work as a winch to control the position of the sails in a system solution where I am realizing this my own way to implement the sheets as shown on the original sailboat Endeavour. This requires my sheet control system to control the length of the sheet of the mainsail i.e. over a range of 8.3 meters. This requires the drum which is turned by the stepper motor to make 21 full turns. Details will be published in my report from scratch of building my Carina.
Just converted this 40yr old twin brushless model (scratch built from a Vic Smeed plan) to a proper independent twin system plus a sound unit. Started off with a 70s Futaba ESC on 27mhz, then on FM, then replaced with an Electronize unit on FM, then to 2.4 and now on 2.4 with twin ESCs and converted TGY S6 (twin throttles). Maneuvers a lot better and makes a better noise.
Nice job.Great to see a boat running built from a Vic Smeed plan.Should do good in a steering competition with the manouverability you have.Lovely boating pond.
Thanks for the nice comment, and yes it is a very nice pond, except when there are a lot of those things with rags tied to sticks racing (shouldn't say that as I've sailed full scale all my life and still have 2 small yachts), and the buoys they leave there are a pain also, (easy to forget they are there) it was full of hire carp (yes hire carp) which were removed as the council wasn't paying the company or some such hassle, but I'm sure they missed some and they will soon multiply and keep the weed down. Bought the plans for the MTB around 1968 and took around 20yrs to finish it. I still have the plans and it only took me about 40yrs to find a photo of the original boat (bit late by then!).
I found this hull at thingiverse last year. I printed the hull from a local shop and rest was handmade.
Firstly I bought a 2426 4200kv brushless 2-3s which was too powerful and too heavy for the boat size. The length is 38cm.
And the 30Amp esc was also too big for it's size.
After that I tried small 180 brushed motor with 20A brushed esc w/brake. it was perfect (still it's heavy😂).
The bridge and deck is made by 1.75mm pvc,torpedos are made of wooden pencil.
Small battery space takes a 2s 500mah lipo. 30mm 3blade propeller.
Excellent video Sakibian, well done👍
and you're very brave to sail such a tiny boat in waters like that 😲
Hat off Sir 😉
Cheers, Doug 😎
BTW: you should put this boat in your 'Harbour', just click on 'Boat Harbour' on the left of the Home page and then 'Add your model boat' at the top.
Happy that you liked the video , will try to post more videos.
And please don't call me sir haha? I'm still 23.
About the harbour , when I registered here I didn't find my country (Bangladesh), can you please do something while your an Admiral 😛
I built this 1/125th scale Amati kit of the Titanic over two years from 2016. it has enhanced etched brass details from Minibrass. Conversion for radio control involved making the hull waterproof with multiple layers of fibreglass cloth bonded with epoxy resin as well as the installation of a drive train and RC gear. With only a tiny rudder, steering is dependent on a mixer unit controlling the differential speed of the propellors.
Landing craft (Tank) 548 a world war 2 Landing craft with Sherman tank and truck carrying British markings of the divisions landing at Normandy. Landing craft is running 2.4 ghz radio gear with 3 channels in use. I brought this second hand and am steadily improving it. Getting the ramp to work properly was the first struggle. See photo gallery for more information.
Zoom 1 (Interceptor) Mono boat.
Built from a Glassfibre hull, brought on Ebay for £35 the hull is a slim mono racing type with a self-righting side cabin it runs a 1400W 14V 2958 4200KV Brushless Motor and 29-S Water Cooling Jacket with additional air cooling fan.
I did not want to use a flexi drive as high maintenance and prone to failure so the shaft runs via two universal joint one at each end. the propeller is a 38mm copper alloy
The ESC is a 200W and water cooled the twin rudders supply separate water one for the motor and one for the ESC.
The rudder are positioned to reduce prop-walk and are hinged to prevent damage if you hit a object in the water and also for ride adjustment.
Turn fins and trim tabs for ride adjustment were provided by a spares kit for another boat. also foamed and added an inner sealed hatch, a rubber bump strip and safety loop.
It certainly looks like we are having notification problems again, First it was very few getting through and now we get 14 YES that is fourteen of the same.
Just fresh off the shipyard, this is my version of an American made Uniflite (firm died several years ago) "Salty Dog" 28. its name is a Puerto Rican slang for escapade. From the same firm who designed and made the legendary Vietnam War Patrol River Boat (PBR), this boat was part of Uniflite's recreational boats line. For this one, I utilized a fibreglass hull I found on Ebay and did the rest with Ethylene 2mm plastic sheets. it runs a 9.6v NiHm battery, a 30A Mtroniks controller, a 3-bladed 35mm M4 bronze propeller.
This is my latest progress on the Barracuda RC Boats 52' MLB, US COAST GUARD "TRIUMPH"CG- 52301. I was up until 0500 this AM attempting to finish sheathing the hull. The deck housings are just about ready for paint. I really don't enjoy covering natural wood, but it's a must to achieve proper detail, I reckon. I'm awaiting 1/8" scribed sheathing for the deck, the fantail semicircle will be 1/16" sheathing, and the outboard perimeter of the deck will be 3/16" light mahogany strips. She's powered by a 775 Johnson-type 6-12v motor turning a 4mm shaft and a 75mm 5-blade Raboesch wheel. The 5-blade isn't OEM, but I reckoned she needed some extra muscle to get to the party in distress.
Here is the Sea Scout Ship Voyageur former 4433. Also Triumph II out of Cape Disappointment and the 44331 from last Saturday's Coast Guardsman Memorial taken next to Cape Disappointment Light
Great seeing your model. I look forward to pictures of her underway. I served at the National Motor Lifeboat School in the '80's (30' SRB's and 44' MLB's) and Station Cape Disappointment (47' and 52' MLB's).
Built in 2016, she is a 1:14 scale Dumas 40 ft. UTB, which I did my best to keep natural wood wherever possible. Powered by twin 775 size 12 volt Johnson type motors turning Raboesch 50mm 4-blade brass wheels. I properly illuminated her with Lighthouse 9v LEDs and adorned with a BECC USCG Ensign. I overbuilt her like my Father overbuilt his airplanes.
Thank you for your interest and kind words. She's my pride and joy, and has given me much enjoyment. I believe she's sturdy enough to break 1/2" ice! Here's a few more pics of the CIRCLE 43 NAUTICAL CRAFTWORKS/ILLINIWEK MARINE SCALE SHIPYARD FLEET
Beautiful US Coast Guard model. I really like the look of their ships and what a superb looking flag at the transom!
I'd love to see some on water shots.
