    Thats some pretty bad damage there... that sucks. So the Esc is done? No smoke, nothing? Just stopped working out of the blue afterwards?

    Yea no smoke. As soon as the boat came up it didn't work. It's epoxy coated do it shouldn't be a water issue. But like I said earlier I think the esc is hurt. I've had some anomalies in my runs and the fact that it only would pick up 5mph on 7s vs 6s has me scratching my head. I have another one of these escs brand new in the box anyway. Just gotta fix my hatch and wait on another motor mount side plate. I had those custom cut longer for the long motor.

      Didn't you have a similar incident before? Rudder wasn't it?

        Why not try the SF300 instead ?

          Yea, I watched that video again and it was very similar. The rudder bracket is bent. Not sure if that happened before or after. I'm not so sure that was my original issue. It's done this same thing three times on two boats. Almost like it lets off for a split second and then full throttle again upsetting the boat. I just went back and watched the video over and over. I don't know. It just got upset for some reason. The rudder has no damage (besides being bent) and the prop is unscathed. Not sure (scratching my head). I just put the Rivercat back together. I'll go see if I can make to break it too tomorrow.

            What? Have you read any of this thread? Looked at any pics? Lol. I've only had a sf300 in it the whole time. I think I even mention it. You no pay attention do you? Lol

              Yep. Esc died. I tried to pull the logs from it and nothing. Saying device open failure. I cut the shrink off and nothing is damaged or burnt. This one I evidently didn't coat but they do coat them lightly from the factory. Maybe I can get it fixed. I'll email them.

                If it locked up the motor even briefly that would cause the upset. I also had a very similar mishap with the Fantasm when I had an early MBP collet slip. You may recall it. You could see the one side come up at the rear and stuff the opposite sides nose in. A singly could easily do this as well.

                    Now that's possible and what I think was going on with that controller for it to do the same thing in two different boats with three different motors.

                      Whew was it! Dead stop from 98. I thought it was gone. Very surprised the hull isn't hurt or split. On my fast builds there will be some motor mount changes for now on. The parts where the brackets slide will be reinforced. I think I'll be doing it on this boat too.

                        Okay, so you weren't using the castle esc with this shocker... The issue is with SF300 then?

                        I dunno man, you keep switching between threads and your boats look exactly the same... its a bit hard to keep track of what you're doing to them lol.

                          Well I don't talk about the other boats in different threads, only about the boat the thread is pertaining too. The shocker has a green top, Rivercat has a white top. I HAD a river at with a green top but it sank.

                          Only thing I said about the Rivercat in this thread is I was gonna go see if I can break it too, today. You'll have to read the 4s rivercat thread to find out what happened.

                              Yes I used the small hvlp touch up gun. I'll have to repaint it now that I broke it.

                                Here's where I'm at on the repair. That a piece of carbon plate flush mounted into the top (top is pretty thick). I'll repaint it when done
