I have a stock boat with 2S, 30C 4500 Lipo's & Octura X642, ESC was re-programed to run LiPo's. I may have an ESC problem & I wanted to get an opinion.
I was running my Elam for only the 3rd time & it seemed OK for 2 min. or so but then stopped dead in water. I turned transmitter off & then on & I was able to get it going again. I confirmed there was water cooling as I could see outlet flow. Then 1 min again it stopped & I could barely bring it to shore with the prop turning a few very slow revolutions.
Question; do most ESC's have a temp cutoff before they overheat, is this what could have stopped boat ?
When I got it to shore ESC & Motor were very hot (sorry no temp sensor). I Let it cool down & hooked up batteries & no motor function, perhaps ESC may be dead ?
If the ESC is dead are there any recommendations to replace the stock Proboat ESC, I think it is 45A or so.
Thanks in advance to any comments or suggestions.
