    "CAT"astrophic day on the lake

    Well, !!!!! For those who followed my "is 40 too much to ask for" thread on my 32" cat on BJ26 motor and esc, its over for a while. I hadnt run the boat in about 2 weeks. I peaked out my 2 and 3 S batts this afternoon for a "quick" run. It turned into a 2 hour deal. Boat was runnin fantastic and for about 1 minute. Then it stopped dead, about 15 feet out from where I was standing. Wind was blowing towards me, but of course, it seemed all wind died as soon as the boat stopped. This happened before. A motor wire came undone out of the bullet. (motor side of the bullet on a BJ motor) Turns out one fell out and one came apart after I pulled on it. I re-soldered those 2 and left one alone. All that was 3 weeks ago. That my fellow boaters was my mistake. If 2 break, chances are the 3rd isnt far behind. Today, the other wire let go.. well, lets back up. As I said, the boat goes dead 15 feet out. I stood there for 30 seconds laughing because at the exact time the wind dies. 15 more seconds and I here a whistling sound and the deck of my hull begins to swell. 3 more seconds, the seem at the front lets go, big bang and A LOT of smoke. I quickly ran the 150 yards to the house, grabbed my rescue rig and dashed back to the scene. Smoking at settled, still above water line. I threw the rescue in and retrieved it. grabbed the hull out of the water and it was very hot. I slowly pulled the lid and was greeted w/ a lot more smoke and the most awful smell. The entire inside was covered in soot. Soot, is that how you spell that? Anyway, I expected to see a turnigy battery all puffed... but nope. Batts looked fine... Esc caps? Looked good. Wire popped out of the bullet I did not repair and also the positive wire had come out of the ESC. There was a nasty black glue like substance all over where the ESC was mounted. I dont know what happened? Perhaps it had something to do with the wire coming out. I was wiggling the steering servo just before it started whistling. And I tried throttling it 5 or 6 times. I dunno but this sux!!!! My kick butt boat is now in pieces, it stinks and the hull is blown apart in the front.

    Heres some pics....

    oh and Im also wondering if it had anything to do with not running an external BEC. It was on 5S. I ran it twice like this before w/ no problems.. no heat issues or anything. Then I added a bec. Then it was giving me lip so I took it out. Something today went amiss.

    Oh, oh and... and... I burnt my brand new gps!!!! Son of a........

    Heres another pic. You can see the black goo nastyness that was left behind from the ESC. (top right corner of the wooden tray I had in there)

    Ive stripped it all apart. Cleaned everything as best I could. I submerged the hull in a garbage can in a degreasing solution and water for a few hours. It cleaned up pretty well. Ive got to fix the hull where it blew apart. I dunno. Im thinking about completely stripping the stringers out. I dont like the system thats in there. Not that its given me problems, just seems bulky to me. So I may strip it, carbon fiber the hull, install a new motor mount and get her back together. But it wont be anytime soon.... well, I can carbon it because I have it, but motor mounts and certainly an ESC is not around the corner. This unemployment thing is really screwin me now... the heck witht the house and truck and boat payments... MY FE is down.... man that sux

      Heres as she sits now... What direction do you all think I should go on this? Just get it back together, or build it better?

        Sorry to hear about all this. It doesn't look too bad. You can epoxy the front back together. To save money, I would just put it all back together after the clean-up and repairs. If you want to continue with the 5s or higher, I would get a himodel ESC (cheap and appears reliable), waterproof and watercool it. You should be back in business fairly quickly...Oh here is the link to the himodel. http://www.himodel.com/electric/HiMo...-200A-BEC.html

          Nah its not bad.. but it sux. No worries on the hull... its the components thats gettin me. I havent got to test anything, so hopefully the ESC is the only thing that I lost. The side of my reciever got pretty cooked. 2.4 Futaba fasst. That may hurt.

          I know someone who has a X-power 100A ESC that he may want to part with... I will be talking to him soon.


          Anyone know any good ways to get the "stinch" out of the hull? Soaking it in degreaser and washing it several times didnt help. I pulled all the foam and all the velcro etc, anything that could hold the smell. It reaks nasty.

            Were you running the BEC or a reciever pack?

              Denatured alcohol works pretty well in removing the black goo and much of the stink, but some odor will probably always remain in the hull. Toss out any floatation and scrub all the components as clean as you can with the alcohol - use plenty, it's cheap.

              The front seam blew because it was very weak - it is tough for the makers to get much glue or 'glass in there. Tape the seam closed well, mix up some epoxy and pour it across the leam. Thicken it with some microballoons or similar to help keep it in place as it cures. It may take two pours, the second after the first cures.

                Thanks Fluid.. and HA... look at my edit in my last post? I did use alcohol to clean the esc, servo etc. I kinda thought it may always smell from here on out. Like a constant reminder of not so good times. Im not so concerned w/ the front crack in the tunnel, its getting into the sponson tips (on the insides of the sponsons) that I cant figure out how Im going to get to. I could probably get my hands close to in there but the stringers are in the way. Thats another reason I was thinking of tearing it all out and starting over.

                  I was running it off the ESc's BEC. I was having issues with my reciever pack so I took it out.

                    From what I understand, the xpower is a decent ESC but is more like 70 amps continuous. I have the Pulso 100a (samething) and I won't push it to more than 60a myself. You'll also need a programming box to program it fully.

                      It says it can handle 5S which is what I want to continue to run. And thats another thing.. I have no idea what kinda amps Im pulling. I really want a eagle tree logger as well. Just one more thing to the list..... Im not liking being in the dark anymore. I want to know whats going on under the hatch.

                      Perhaps I will just take my time, get it done when it gets done, do it "right" and mess with the SV until then.

                        Spray it Febreze every few days and that will help with the smell, also leave the hatch off.

                          When I split the seam in one of my cats, I did what Jay suggested. I mixed up a good amount of epoxy, poured it from the inside till it started seaping thru. Then I wiped off the excess and clamped it closed (paper clamps) No leaks and you can't even see the repair. I also used long q-tips and fondue sticks to spread the epoxy inside. I'm cheap.

                            I don't think it would be a good idea to run an ESC to it's max ratings. You want some headroom as the load on the ESC is dynamic and may spike beyond it's average. I understand about the money issues. That's why I was suggesting the himodel.
