After reviewing the tech specs on the esc of the BJ 29, I read it could handle a 6s setup in 30c. I was in the local Proboat dealer today to get my 2, 3s lipos. When in there I met another guy who was the first to buy the BJ 29 from that store, I was the 2nd. He saw me buying the lipos and said "I just got those lipos last week, man that thing is fast. Unfortunately I lost my boat to fire after running them". I said "whoa, wait, your boat caught fire with these?" He said it had nothing to do with the lipos but that there was a malfunction in the esc he believes since the fire was in the connector that goes out to the motor. The store owner also felt it wasnt the batteries but the malfunction. Even proboat said the same and is sending him a new boat.
So, comforted, I went ahead. I put the batteries in and ran that baby 6s for the first time. It is sick fast! However, about 4 mins in, i lost power. I sent my Miss Elam out on a recovery mission. When I got my BJ 29 in, I removed the top to get a plume of smoke in my face and a foul smell. I was fortunate. There was alot of smoke but the only thing that had happened was the cable from the esc to the motor was melted and separated on the "crimp" in the middle between the two. Im not sure what it is called or what purpose it serves but its like a wire crimp (though I think it serves a different purpose).
Anyways, it was hot (the wire) and even left a burn mark on the interior wood but fortunately no fire, just a ton of smoke and now a dead line. The rudder still worked and when I pressed the accelerator i could hear it try but it wouldnt do anything I guess since that wire was melted apart. It is the black wire.
This is 2 out of 2 boats sold from that store (the first two) that have now caught fire (in a sense) when going 6s (staying in spec). i'm new to this hobby so IM just curious if anyone knows what could be causing this. Should I upgrade my esc? It is wiring? The motor? The batteries (Speedpack 5300, 2s, 30c)?
Im taking it in this week to get it fixed as those guys do a good solder job, but IM curious if (before I get it in MOnday) anyone has any input. Can i Just resolder that wire myself and go back to 2s until I figure it out? What is that thing in the middle, will it need replacing?
Thanks guys!
