Hi. This is my 2nd scratch built boat since lock down began. The first was the H S L 103 finished 6/7 weeks ago. Still waiting to be tested outside of workshop. This one is built on a fibre glass hull,and has a length of 44 inches and a beam of 16. My power plant is twin out runner motors purple power. 600kv, running through twin 70 amp ESC and with 4 cell 5000 amp lipos feeding them. All accommodation is made using 6 mm three ply. And every fitting you see on the boat was scratch built by me. Lighting system is 12 v grain of wheat .props are three bladed brass 45 mm by prop shop
My dad built this over a long period of time, starting in the '80s. The hull is fibreglass and the rest is scratch built from plastic card, balsa, ply, wire and anything else he could adapt.
Although he installed the motors, props and rudders he never completed the RC installation or tested it. I inherited his boat models a few years ago and wanted to "finish the job", getting the model on the water. After installing the RC gear and batteries over the last few months, this weekend was the first sailing outside the bath at the Valley Gardens boating lake.
Happy to report that it sailed really nicely, seems to be reasonably stable although I did restrict it to calmer times when the MTBs and faster boats weren't running !
HMS Cadiz was a battle class destroyer, laid down and launched during WW2 although she didn't receive her commission until 1946 so didn't see combat with the Royal Navy, serving with the home fleet. Due to the changeover in pennant numbering she was originally allocated R09 and later, when the admiralty decided to revert to the D for Destroyer pennant numbering she was assigned D79. To reflect this my model has D79 on the starboard side and R09 on the port side.
She was sold to Pakistan in the late '50s, and renamed PNS Khaibar. She was sunk with the loss of nearly all hands in 1971 in the indo-Pakistan war.
I thought as the lake is still full of weed this would keep me sailing built from light ply fibre glassed inside & out then painted length 33" width 12"height 16" to top of the prop
70 amp esc aircraft brushless motor 11" prop
I am busy with a landing craft i thought this would be another one to beat the dreaded weed 😱
Scratched built on a fibre glass hull, home made sails with a modified star wars figure
Bought from a member of our Kingswinford Model Boat Club, Peter Ellis, who sadly passed away
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.
Billing boats, which took me 3 years to build.Hull was planked and theh fibre glass. Boat has full functional remote with seperate port starboard control,rudder and bow thruster. full inside and mast lighting.
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.
Scratchbuilt WW2 1/24 Scale Vosper 73' Type 1 MTB. Built in 2016, in company with a friend's 1/24 scale BPB MGB.
The Vosper hull is built from balsawood and fibreglass. The upper deck and superstructure is from balsawood. The weapons and fittings are from brass, aluminium and plastic. The 20mm and gunner can rotate.
Both Fairmile D boats 1/24 scale and are scratch built. They have both been about 6 years in operation.
MGB623 is an MGB, flying the Norwegian flag and belongs to a good friend.
Mine is MTB741. it is powered by 2 Graupner Speed 700 12V motors with NiMH batteries. The 6 pdrs and 20mm guns can rotate. it has a balsa planked hull and fibreglass skin. Decks and superstructure are also balsa. Guns are from tinplate and brass.
Excellent boats with great scale performance. I like the Fairmile Ds as they are good subjects for modelling and at static displays they always attract a lot of attention.
Hi. Just put this back together after the 3rd brushless motor caught fire. Made from a rejected glass fibre hull which I bought cheap at a show. I have now learned how to do glass fibre repairs.
Hi, thanks for the info👍 I'm new to BLs, but learning fast, and your experience confirms my growing suspicions that outrunners not only deliver more torque than inrunners (size for size) but that they are also more reliable and seldom need water cooling.
Your new motor seems to be a larger diameter 58mm?, as opposed to 31mm for the old one, so I begin to wonder if the old ones were simply overloaded by a big prop causing them to draw more and more current and hence cook! 😡😭
Check out this test drive (Italian)of your new type motor!!
cheers Doug 😎
PS Caption says that with more than 3/4 throttle the boat becomes unstable! Then it flips 🤔
PS Don't worry about 'adding up' the Watts and Amps!
True the spec says 12.6v and 35A, which theoretically gives 441W.
And the power is rated at 220W. This simply indicates to me that the motor scoffs 441W of power (at Max ratings) and spits 220W out again, i.e. ~50% efficiency 🤔
Almost any decent brushed motor will beat that! But with other penalties😉
Cheers Doug 😎
Old boat of my fathers built from scratch in balsa wood, and fibre glassed inside. Use to run a small diesel engine, I took over it and initially put an Orbit 805 motor in then later a better spec model car motor 545/550 water cooled. Finally I swapped it for a 1.25cc glow engine and this video demonstrates the speed with the glow engine. Was almost too fast for the hull, tight turns caused it to nose dive, and plane/wobble badly on its side. Great fun and cheap to run.
That video was from 9 years ago and that was the camera on the latest phone for the time. Since power boats are banned at our pool this is the only video i have of the model running, sorry.
Posted for posterity. MY other boat 26cc kawasaki engine was same time pre IC's ban.
