Brushed or Brushless Motors
Chris F What size is the boat in your picture with outrunner kv? I'm trying to do the same thing with a S&G Gentleman's runabout.

Brushed or Brushless Motors
Outrunners are generally more torquey than the equivalent sized inrunner. So for a large model, say 3-4 feet in length, and outrunner would be my 1st choice. In comparison, as Chris says, for a small, fast, lightweight model, I'd go for an …

Brushed or Brushless Motors
Hi Chum - no that's an outrunner. I'm using them in all seven of my Fairey builds. The only inrunner I've got is for my non-Fairey water-jet project which needs a higher revving motor and they are more effectively water-cooled using a water …

CF, are you using an inrunner in the boat you mentioned?

Brushed or Brushless Motors
Hi - I've heard that mentioned a couple of times but as long as a decent quality ESC is used then it isn't a problem. I'm not talking expensive here as I use HobbyWing Quicrun and with my Overlander motors my boats can pull away smoothly at …

Brushless Motor
Some weeks have passed and I have had one or two opportunities to further test and experiment with the power train set-up. With the three fuses between motor and ESC removed I carried out trials using a watt meter, and different size props. …

Re: Brushless motor sync problems
Thanks DG. To answer Doug and Isaac's points. One factor that I had omitted to include is the displacement which is 8.5Kg. ie it is a heavy boat. My wish was to make this boat seriously fast, but not like one of the super-fast electrics. La …

Heartily agree Isaac I'm also deeply disappointed that, despite all the informed and qualified advice that he received in this thread, he still insists on using the 3 fuses in the motor leads️ What possible "scientific" advice he could have …

Re: Brushless motor sync problems
Recall me questioning your use of 5S battery? In my opinion a 3S battery for that size boat is all you need. I think the over voltage of the 5S battery has overwhelmed the ESC and it went into some sort of defensive mode and cut the power t …

Re: Brushless motor sync problems
DG - from what I know of the 800 and 850 motors the first is low revving (4280 rpm) whilst the 850 is higher revving at 8310 rpm. I have seen the 800 used for tugs and similar slow moving craft that require lot of torque. I used an 850 in a …

Re: Brushless motor sync problems
Hello DGoss99 and thank you for your input. I will try to answer your questions. 1. I left the 3 motor fuses in place. The fuses are 25Amp. 2. I should have mentioned the main breaker is rated at 40 amps, and the ESC at 90 amps. 3. I have n …

Re: Brushless motor sync problems
Hello all, This morning I borrowed a watt meter to find out more about my boat set-up. By finding out the amps and watts when at full throttle I have compared these figures with the specification of my motor to see whether I can safely incr …

Hello Alessandro, and thank you for your latest submission. You raise some interesting points and I now hope to be able to answer some of these. One or two club members at LBMBC have given me information that should help me understand how I …

Re: Brushless motor sync problems
Flaxby.. You have done this all this pretty much by the book. As I commented before, I would replace the 3 blade fuses in the Motor Phases with links as they are an extra single point of failure and maybe a liability rather than a help. The …

Re: Brushless motor sync problems
Thanks for the info DGoss. Not having any previous experience of handling large lipo batteries I asked people reading this site for their recommendations. The majority response appeared to favour fuses on each of the three motor leads, in a …

Re: Brushless motor sync problems
Fuses ? I asked the question whether to use a fuse or fuses and the best information received suggested a total of four fuses, viz. one between battery and ESC, then three between ESC and motor. I have installed a 40A circuit breaker for th …

Doug, thanks for the advanced "skip" warning. Seems like there is enough words posted on this topic to write a book. Also seems to me that for scale model boats powering a model is not that difficult. Basically supplying power to a motor th …
