Mg fire!!!

[hobie]

Hello all...
Well, can anyone tell me how to get the burning smell out if my hull?? I am NOT impressed with the electronics in this boat!!!!! Yesterday, I was running on 4s when it just stopped working. I got my buddy to loan me his bj esc, and on 4s in about 3 min, the boat was on fire!!!!! Smoke eveywhere. I must say it did look cool, if only I was having a bond fire!!!! After getting it back, I noticed the esc had popped, blew up! Now we both don't have boats to run.
I have taken everything out. Esc is dead, fancy digital servo is wonky, and I'm not sure if anything else will work. I did have the BEC removed, had run it on 5s a couple of times. But I was trying out some new 5200 7.4 team Orion lipo's, so I wasn't even loading up the esc. It took 5s the day before with not even a temp of over 83???

My question, to a seasoned person at proboat.... Andy or Darrin, is this normal, and is this a warranty thing? Or am I out a speed control?
I emailed Proboat last week to ask about a crack in the hull. They said to bad, should have looked at it beore you took it out of the box.
I am not looking forward to thier response.

Guess I get to run ol faithful.... The good old P1.

OMG!!! I can't stop rolling around on the floor!!
Funny you should ask, it's the replacement one from PB last week.

I will post a pic a soon as I get home. I forgot I took one when it happened.

What prop?

Sorry to hear you are having issues. You'll have to work with the Horizon customer service department to figure out what they might be able to help you with. I have no idea how that end of things works.

However, and this is just my opinion, if you had TWO ESCs fail in the same boat, then it points to something OTHER than the electronics being an issue. Could be a driveline issue, could have something to do with removing the BEC cicuit, could have something to do with running a 4S ESC on 5S... ProBoat ESCs just don't typically go up in flames... In fact, it's rare that they stop working without REALLY over loading them.

Might be too late to find out now, but was the driveline TRUELY free? When you put in the new shaft, did it go cleanly and without ANY binding go into the coupler, indicating good motor alignment? Did the stub fit into the strut without any binding?

Again, it would be EXTREMELY rare to have TWO ESCs fail in a row, without something else being the culprit. Not impossible, but it's certainly not something one hears about with these ESCs...

I was running 447 prop. Motor was temping at 75, same as the esc. All nice and cool. Or at least I think. Never had it hit over a 100.

Darin, yes, the new shaft went in with no problems, free and clear, the only thing was it was a tad long, and to solve that, I just moved the motor back. But it was running so sweet and very cool with the setup I had. Seemed very odd the first one would stop and be very cold to the touch. The second one just blew up, I heard the pop from the shore.
But that's the first thing I looked at, and motor was ice cold. Shaft still spins freely

I thought you were joking about the flex cable thing!! Sounded like it cause of all the troubles people have had! Lol!

It's fine, just greased it yesterday before the mess happened.

Inside is clean for the most part now, I sanded everything down and put a new layer of clear coat over it all. Smell is still there, I'm assuming it's up where I can't get at.
I will get a new esc from here, and try again. I'm thinking 120 amp minimum?? Don't want any issues down the road. A decent one should be able to handle all the new packs I got for 5s setup. Will keep posting my results.

[Rumdog]

If you ran the x447 on 5s, you seriously over amped that esc.

[hobie]

How come the esc was only 85-90 degrees?

[ray schrauwen]

How long did it take you to retrieve the boat? Doesn't take long to cool off ...

In future try to use Eagle One tire & rim cleaner, rinse out with hot water in shower, no mess, no smell !!

[hobie]

Didn't take long, it was only 15 feet from the shore when it popped. By the time I turned around to put the rescue craft in the water, I could reach it with my oar.
The one that caught fire was got for 10 min or so, the previous one was cold, 73 by the time I got it. But the motor was warmer. 90 maybe. Tried another little motor, made the motor smoke. Hooked it back up to factory one... Moved it, but was making a banging sound, and would only spin for a second and then stop. Hooked up a new esc to factory motor, all was good. Or so I though.
I'm going to start changing all my speed controls out to at least 120 amp or greater. These 40's and 60's are for the little toy boats from what I'm learning.

where is that promaced pic? i have seen a few cars on fire but never a boat!!!!!

[Rumdog]

What? Now you've been running different motors? I give up. It's making my head spin.

[hobie]

Sorry, almost home.
Fire was out when I took the pic. Surprised to are there wasn't more burnt area
