problem with 200amp swordfish esc

[roost28]

I have a 200amp swordfish esc in my impulse with a leopard 4074 2150kv motor running on 4s and the esc keeps shutting down after 2 laps like the lvc is turning on. I set it all the way down to 5v cuttoff and it still does it. any ideas?

thanks

Set everything to Automatic or factory defaults and try a short run. I ran one in my Whiplash 40 with a TP Power 4070 motor, 1250 KV on 6S2P and it worked fine. I mean, it worked until I pushed it so hard the motor lead melted off the esc. I ran mine on all Auto settings from factory, all I did was calibrate the throttle and then ran...

Not sure why people are having these issues. I still need to call a buddy about his 220 to help troubleshoot the same problem.

What cells exactly are you running? 1P or 2P??

Check for water flow too, it could have thermalled but, not likely... I made mine thermal once on first run after 4.5 laps but, that was a BIG prop.

It's not thermaling, I am running 4s2p with an m445 prop, it's not even warm

I'll try the auto setting and see what it does.

So I got it running and everything seems to be good now, I ran it for about 5m and the temps were all fairly cool but the caps on the esc were around 140 degrees Fahrenheit. Is this normal or should I try a smaller prop? I am currently running an m445 with a leopard 4074 2150kv.
Thanks

That is close to normal temps (high) but, the 5 minute run has a bit to do with it.

Did you set it to Auto and see an improvement?? This is odd IMO, we should be able to choose our own settings and not have a problem instead of using Auto mode.

An extra cap bank may help with temps for 5 minute runs.

I tried the auto setting and it was choosing 5s, indicated by 5 beeps after powering up. So I did it manual and it worked fine after that. Maybe I just didn't do it right the first few times I tried to set it.

I'll time a 3m run and see what temps I get, I guess these boats really hog power.

Swordfish esc are junk i had a seaking 180 never any issues always cool. I hooked cables up backwards one day and blew it up. Bought a swordfish 240 that lasted 100 feet. So bought the 200 a and that works but my batts just get puffy i have a leopard 4082 2 3s packs x442-x445 prop. I used to run x448 with my seaking no issues. Owner of ose wont help me out a bit. With my seaking set up i got 100+ runs destroyed 1 batt in one year. Swordfish setup used 5 times destroyed 2 batts in 1 week. Unless owner of ose makes things right im done with toy boats i cant afford to destroy any more batts

I can remember when I first started at FE RC boats. Way back an esc was $200 and it would only handle 70 amps, motors were around $300 and batteries, well, sky was the limit.

Basically, I'm saying if what you think you are spending today is big bucks, you have no clue. Another person has noticed that you have slammed these esc's in at least 3 threads so far. This isn't going to help you with anything. If you want help, ask for it after your first problem like your SF240 that you say lasted 100 feet. Was it new? Used? Did you calibrate throttle, did you ask for help before it all blew up? There are so many questions unanswered before you even got the SF200. You need to start off small. I've been at this for at least 15 years, more like 20 and I've never built a boat that needed a 240 amp esc until 2 or 3 years ago. Some times you need to crawl before you walk or run.

Any unanswered questions you can find in other thread.

With all due respect in reading your posts it's clear that the "owner of ose" is not the source of your problem. You've been given some good advice, take it and continue to learn not to burn.

Good luck!

Look in the mirror, then you will see the root cause of your problem.
