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😉

So, here's my current project in the works. I got a nice 25-inches Deep-Vee fiberglass hull a while ago and now (finally) have a concept for it. Almost by accident I came across a plan for an American bass boat which in turn reminded me of a boat that caught my attention when I was a kid while reading a boating magazine. The boat is a 28-footer from a now defunct firm named Uniflite. it was a small deep-sea sports fisherman called "Salty Dog". Uniflite was very well known within the American boating circles during the 60s, 70s, and 80s. Uniflite created and supplied PBR river patrol craft to the US Navy between 1965 and 1972 for rivers in Vietnam using an already existing pleasure boat hull and adapting jet nozzles for propulsion. So, I just created a prototype template of the cabin so more to follow 😎.

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.

Acquired as an empty hull a year ago. it measures 5'6" from stem to stern and was steam powered. it is carved out of one piece of timber. Now electric powered and using 12v invalid battery. if I can extract the picture from the computer I will include it !! if I can't you can do your own research.

Ramura Hull - wooden boat from 1960's use to have an Ohlsson and rice engine but now runs Kawasaki 26cc Flymo engine.
New homemade carb and also tried running on glow fuel and a glow plug, instead of petrol and the electronic ignition.
Not used any more IC engine's banned at our POOL.😱

Trying to reply to your query about Huntsman power plant, cant find the right place.... anyway cant give you a sensible answer as I dont know. it's an old brushed motor given to me. Will operate up to 24 volts and I'm running it on 14. I think its just right.
Cheers

a 30"scratch built pt. boat, I built hull from .8mm ply using a resized eezebilt 20" plan.
the deck fittings were copied as best as I could from photos and drawings found on line. powered by 2- 2200kv brushless out runner motors through 2 20 amp speed controllers. twin contra rotating props twin rudders fast and light a pleasure to build

I hope this helps if not let me know & I will take more pictures
i was able to put a high deck in because of the size of the hull
it might be difficult to do this with the smaller hull take a look on SLEC they do the River Police Launch (last picture)it appears to to be risen at the front to take the motor etc
The Vintage Model Boat range are now being produced by SLEC Ltd. All our kits come with all parts cut by CNC router or laser, plus all the necesary strip wood is included, along with building instructions and plan.
The River Police Launch has been based on the old Veron Kit from the 1960's that we all loved at that time. The model is not a scale model but embraces the boat design of that era. The kit is now fully laser cut so all parts are pre-cut and most of the parts are now made out of high quality ply, so obtaining a good finish is easier to achieve. The model can be powered by a 7.2 volts standard buggy battery pack or ic power of .5-1.5 cc engines which is not in the kit, also we have not included any running fittings as we feel a lot of modellers will have or would like to choose for themselves, but we can supply these fittings if required.

By the way, you may get some Viagra (10.8v Nihm battery) on Ebay. You will find them with either AA-type cells and C-type cells. I do prefer the C-type cells. Expect to pay around $45-50 USD. I bought some from a German store named "www.Conrad.de", but it seems they no longer offer them.

nearly there i think a few tyres around the hull will complete it what a pity the model shop do not sell them 🤔

Original design "Express Cruiser" type boat. Old home-made fiberglass hull built in UK in the 1970s and rescued from previous owner's garage. Model built during April-July 2015. Approx. 1/24 scale. in trying to emulate a Bertram Bahia Mar boat, I ended up with an originally fictitious design. Real life boat could be a 32-footer (9.75m) yacht. 3mm 9v LED navigation lights system. Runs on Mtroniks G2 3A Hyper BEC 6-12V 15A Constant controller, Biao123 A2122 brushless motor, and a NiMH 10.8v battery.

Original design "Express Cruiser" type boat. Old home-made fiberglass hull built in UK in the 1970s and rescued from previous owner's garage. Model built during April-July 2015. Approx. 1/24 scale. in trying to emulate a Bertram Bahia Mar boat, I ended up with an originally fictitious design. Real life boat could be a 32-footer (9.75m) yacht. 3mm 9v LED navigation lights system. Runs on Mtroniks G2 3A Hyper BEC 6-12V 15A Constant controller, Biao123 A2122 brushless motor, and a NiMH 10.8v battery.
Model kit made on or about 1969 by defunct German firm Robbe based upon Chris Craft Roamer motor yachts of the era. Hull appears to be inspired on 1950s Chris Craft Constellation series. Model tried to emulate a 46 feet version. I got this one half-built and adapted as a gift for my child inspired in the "My Little Pony" characters. Approx. 1/20 scale. Authentic Chris Craft Roamer 46 measured 46 x 15 feet. it runs with a 4-bladed 40mm metal propeller, 320A 7.2V-16V ESC 30A constant, a NiMH 9.6v battery, and a Mabuchi 540 Motor.

Looks like a Graupner 'Commodore'. I built one in the 70s and looks identical (see pic)

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 🤔
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 😎
