Well this started off brushless but it had no soul or character, I bought an Os 40 fourstroke and converted it to be water cooled, I then made my own reverse gearbox and clutch assembly and fitted a water pump so the engine will keep cool while stationary. it has nav lights and a working searchlight that I can move while running.
Extremely impressive, a water-cooled four stroke with reverse. You must have some great metal working abilities and nice equipment. Video was fun to watch! Joe
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 .
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.
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.
This is my 6 month in build of a fully working fishing boat .she has a real I have modified and put a 20kg winch servo so u can real in and out and have drill a hole in to the real and put another servo so u can lock the reel out to.made a back plate on the end of a cut off rod and bolted in to the hull. She has full fpv from the wheel house with a 360 spin HD camera and have even put a digital amp meter so u can look at to and see how mUchida power u have left full running lights controls off hand setc to twin brushless motor water cooled and a large 100 amp esc with air fan and own power supply going to take her out tomorrow for her maiden voyage. Witch has bin a real long time coming and a lot of blood sweat and stress to get it all to work but finally I'm there hope u all enjoy and like what I have dun thanks for reading my post Ben
Its maiden voyage took place at the Knap at Barry South Glamorgan. with the VGMBC.
It's a Robbe kit "San Diego" built by a chap on this website "sharpy1071"
Leopard 4074-1400Kv water-cooled motors 100A Mystery ESC's.
After a few teething problems with transmitter setup, everything went fine.
Maiden voyage of American Enterprise on Poole Park Lake 10/2/15. Leopard 4074-1400kv x 2 Mystery 100a ESC x2 all watercooled. 4 cell lipo 6500MA. Went very well until one brand new ESC packed up! Second one to do this, bit iffy I reckon. Turns a treat and very scale like in running.
Another winter project for myself this time. Twin brushless motors/ESC's all water cooled. interior and deck lights got some figures for deck then onto the lake when the weather breaks.
Thank you figtree7nights, up for sale now!! it's stupid on 4 cells, mad on three but behaves very well on two. I sail it mainly on three cells as I have more 3 than anything else.
A winter project for a friend who hasn't the resources to build, so I helped him out. nearly ready for the lake. Twin brushless motors/ESC's all water cooled and a few interior exterior lights.
This looks very similar to mine. I bought it as a damaged boat and it will undergo restoration also with two brushless motors etc. it should be quite fast as I imagine yours is. However it will probably be mid 2016 before its completed as my new workshop is yet to be completed and all my boats are in storage> 😟 😯
Water cooled 2815 Outrunner brushless motor. 50A water cooled brushless ESC
Top speed: 45 km/h. Powerful 37g rudder servo. CNC aluminium alloy rudder. Shaft drive system: 3mm flex cable drive. Twin blade nylon propeller.
Length: 740mm (29.13"). Beam: 180mm (7.09"). Weight: 1140g (2.51lb) (Model only).
Hull materials: ABS injection moulding
Get about 35 minutes out of a 11.1 v 2200 mah lipo
But most of all good fun 😊
Built from a kitishack kit 56" it runs on two Hobby King 750kv brushless motors I used brake pipe to make the motor cooling coils two 200a water cooled esc,s, I got the 5mm shafts & 42mm brass props and couplings from SHG models the power is supplied via two 14.8v lipos this is a really powerful boat
I think with two beefy out runners, 42mm props on 14.8 lipos it should be a very powerful boat. However I like big boats properly engineered. Well done. 😀
