Brushless motors and Scale RC Boats
Вставка
- Опубліковано 21 жов 2016
- I take a tried and true scale model boat which already works flawlessly and give it a heart transplant. Out goes the 545 motor and in with a brushless motor the size of the 20 cent coin. I have some exacting requirements for success, so take a look and I hope you find it helful.

Drawing up plans for a 46'' stern wheeler, looks like you've given me the power sys. Thank you Sir.
Ironic, I bought all the stuff to make an R/C stern wheeler myself last year around Christmas and as it does life cropped up. But I am dusting off the parts and starting work on it again. good luck!
I watched this video earlier this year and took your experience to power a 1970 cica Swedish lifeboat these brushless motors are so incredible I used a belt drive from Amazon 2.5:1 and it all went very well crazy sailing time and super seed control. Thanks for the push I needed.
what a work you done here. Nice work.
Fascinating Captain!
Good boat and a very quiet piece of water for it.
Great video, just viewed it in November 2021. I like the idea of using the LiPo battery and lighter motor to save weight... this should make it easier to trim heavier ballast if needed deeper in the hull and help get the Center of Gravity lower in the hull where it will do the most good!
She is a beauty. thanks for the video.
Great video, Thanks for sharing :)
Great Video
Great job!
sweet set up
Nicely done.
Wow!...And yes it is very helpful....
Great video. I’m building a moderate size scale tug and will use a 750kv BL motor. As low as I can find that fits. I used a high kv BL in a test run. That just does not matches the torque that I nees instead of high rpm.
Where did you find the belt drive?
Nice work. You will loose lots of efficiency with a gear reduction. The trick is to choose a very low KV motor and to run a lower voltage with a large lipo battery. Perhaps a 2S? As long as you have an esc that can run well at 2s, it is always good to get a slightly larger esc than you need.
Nice conversion. If efficiency is not a problem then there is no need to change anything.
Good advice. Even more efficiency!
Reading this in 2021 and this is the plan I had in mind. Im just learning hope Im good with a 320kv motor
@@stpatr3k If you want very low speeds with high torque you might also consider a brushed motor but some of the crawler ESC's can be setup to run very low speeds these days.
@@izzzzzz6 I saw that, the one with the reduction gear. Anyway the 320kv is on its way, Im just gonna try that first if it doesn't work, I will try the brushed one. Thanks!
@@stpatr3k Don't forget to play around with prop sizing.
How do you adjust the ESC to be able to go forward and backwards? It comes with the ESC, or you had to do something?
Great job!
Tank you!
You use a ESC for cars. It has revers built in. Not all, but most do.
Great report, very informative.
Any chance you're planning to try it with a tug towing load?
No that is not an idea I have planned for. Sorry!
I used to sell those electronize speed controllers here in Melbourne and these can be adjusted for slow speed or faster depending on the use needed. To be honest, it all depends on the motor used, I use printer motors on my model boats and they use stuff all power and I can have them just very slowly turning over and have full control. These motors you are using do not like 6v gel cell batteries and I use them for power and ballast. Each to their own I guess.
Any links on how to hook that up. I have a few dead printers
To hook what up ?? the printer motor or the speed controller ??
well both I guess, could be a popular video. many people have old printers.@@TimsBitsnPieces
No need for drive reduction with brushless motor. With more rpm, your creating more heat with causes a decrease in performance and productivity. Heat is the enemy of performance. Also with a good remote, you can set the maximum amount of drive speed you want and also have a cruise control as well. Would work good with your driving style.
Thanks for your thoughts, and for others to read also
Hello, can you please advise the model names/partnos of the; esc, motor, battery and gearbox spec. Many thanks. Mike
Where did you buy the new motor etc from please.
Can Anybody suggest me plz 545 dc motor similar bldc motor
um "there is two issues"??
Why anyone would recommend an outrunner motor for a boat is beyond me, one bit of water on it & you're motor is toast.
They run under water. No brushes and lacquered wires. UA-cam it up. A splash wont bother it.
Outrunners are designed for torque. You can spin a large diameter propeller without the need of a reduction drive. Innrunners are high rpm motors that will need a reduction system, and in some cases cooling.
