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
Taped some plastic on the hull to protect it and took it for a skid round the back yard, (you can see boredom is setting in😀). Can't wait to try it on the big sports fields (maybe bolt some wheels on it😁) and the big estuary down the road. Bit loud at the mo due to the wooden prop. More than enough power! Could do with more rudder travel and maybe a bit more area.
Super tug and steering wonder. Bought as a kit and made from wood and plastic.
There was no instructions, and without them a nightmare.eventually getting them put the basics into perspective, eventually building the boat.i changed the motor to a 480 and made my own propshaft on the lathe, also a brass rudder, which is operated by mini servo.The esc is a 10 amp m.troniks which works great small but powerful, turns in its own length to port and starboard either astern or forwards
💡Scratch built from plans. Plank on frame. Large brushless motor,150 amp esc,length is54 inches custom made propshaft ballraced at each end and middle. Has running lights,and large very bright searchlight. Flack Mats were made by better Half. Everything else was scratch built by myself.
" Elsa ", is a steam dredge barge built by Buxton Model Boat Club member Dean Ratcliffe.
She is roughly 1.24 scale, approximately 43 inches by 8 inches and is made from recycled and up cycled materials wherever possible. She has a single rudder and propeller, powered by a single motor from a drill, and two 6v lead acid batteries. She is a totally freelance design.
Found a way of pulsing the water using the pump of a dead smoker (Hen Long smoker that is) In this test I used a pump to prime the smoker pump (smoker pump on 2s) and the rest is just syphoning through the pump to the smoker. You can vary the amount of 'spitting' from the exhaust by running the pump at low voltage or maybe using a peristaltic pump with a small flow.
I did not connect the fan powered smoker unit as I ran out of silicone tube, but the result should be the same as the last vid but with 'spitting' water. Using the smoker pump for water is not perfect as it would need sealing properly, and it's cumbersome, but you will get the idea. I have ordered a couple of small air pumps, so might have another crack when they come. I'll use them at the exhaust to disrupt the water flow if they are powerful enough, rather than use the smoker pump.
Re - As the saying goes good one Cyril
Thanks peter, not quite perfect but it's certainly heading in the right direction. At least it might get people thinking about something different to try with their boats, which if tuned right, might give them extra Brownie points at the pond. Would also be even better with a good sound unit! I'm sure someone will come up with a good idea to refine it sooner or later, (probably on the long drop at 2 in the morning!😁😂!) If I can refine it more, I'll post the results.

Made this in about 6 weeks for my son who was not interested so I now use it for general on water filming etc. It was scratch built from a few photos and is all balsa construction, sealed and painted. Powered by a single 12v 380 motor with a 28mm 3 blade prop. Runs flat out at around 15,000 rpm.
I haven't run nitro boats for a number of years now Doug, same with the planes, everything has been converted to electric long ago, (all the nitro planes included.) No more mess and smell of burnt fuel in the house, no having to take a roll of paper towels and soap sprayer and wash your plane or boat before putting it in the car, and no more having to put a plastic 'nose bag' on the planes to hang them up so you don't get oil dripping on your carpet!
Re- Graupner 'Premium Line', certainly sounds like their quality has dropped, you couldn't fault them in the 70s, gone the way of all the others due to competition from the home of Oolong tea by the sound of it.
"everything has been converted to electric long ago"
Know what you mean John.
I've still got a 5ltr canister of pepped up glow fuel kicking about in the cellar.
Probably degenerated into uselessness by now🤔
Maybe I'll stick in the car or use it to start the barby😊
Re Premium line-
Belfast wasn't so bad, but had the same crappy plastic props held on with grub screws.
So she's getting threaded shafts and brass props from Raboesch 😉
On Graf Spee though I noticed a lot of resin casting faults, evidence of air bubbles and smudged detail, as well as over / under-spray in the painting and lifting of the wooden decks.
Had to inject liquid CA glue round the edges to stop it peeling ☹️😠
Best thing on both ships were the faultless hulls with double skinning!😉
One thing surprised me with Belfast though-
the recommended SLA batteries don't fit! I couldn't get them in any which way 🤔
Not to worry, they go in my 1:72 destroyer with ease 😊
BTW I prefer lapsang souchong 😋
This is my latest build and first time at scratch building. Other than the hull I've done everything else so far and learned a great deal in scratch building. The hull was built for me by John Elsy of Newcastle as I had no experience of lifting details from the basic layout plan I had, but will learn this soon. Various stages in the build to date. it has a Graupner 500 ECKO motor pulley drive. Motor sits above the propshaft on special engine mount and the shaft has an oiler. 2 ch Futaba `T2ER 40 MHz radio which is all hidden under the false planked aft working deck. it will run on a 12v 7amp gell cell battery with a FR30HX Electronize ESC. Currently building one of the cranes.
here's a short clip of my RTTL tearing up the lake :-) she has 2 MTroniks 600s driving 30 ml brass props both rotating in the same direction as in the real boats and she has 2 x 4300 mAmp ni-cad batteries in. Lasts for about 15 mins full chat :-)
Hello !
Som more Pictures of my Fairmount Alpine , A little bit forward on the deck
propshaft and rudder is mounted
the towing winch is mounted and working
more
pictures is comming
