    Stock ESC burned up

    Hey everyone, I was running my MG yesterday when it just stopped working. I charged batteried to make sure I didn't have a bad battery, blah blah blah the usual check over stuff. I took it out, and it was definitely burned. Smells like a burnt esc does. Anyone else have any problems? I am going to send it off and get a new one I hope, because it is still under warranty. I will probably put a different one in, but what is a good replacement ESC?

          * Any binding in the drive shaft & proper direction flex cable?
          * Properly lubed shaft?
          * Gap between the drive dog and the strut?
          * Any half throttle or less then full throttle running the majority of the run?
          * Any excessive turning/hard constant turning where the boat would be on/off plan often?

          Any/All of those could lead to esc failure.

            well, i mean i have to turn it, but not excessively, and no binding, the boat was running fine the last 3 of 4 runs, and everything was how it should be.

              Yea I hope your turning lol. What I mean by excessive turning is a lot of new guys like to make super tight turns like trying to make the boat do a donut or tight figure 8 or something and it's just horrible for the esc.

              You may be the 1 out of 100 that got a bad one. Horizon should cover it no problem, there customer service is awesome!

                Yeah, I've dealt with their C.S. before, we fly planes, and we have bad stuff here and there, and they take care of it no problem! Thanks Diesel!

                      Yeah, I'll give them a call tomorrow, and I've never had a problem with them.
                      and Jim, I would run it until it started driving really slow, but I had the ESC programmed with slow cut-off, lipo, and I had greased the flexshaft. It was probably time to re-grease it, but it was running just fine and then cut out. I'll send it to them.

                          If you get a new esc from HH sell it and get a SK180..Especially if you plan on 5s running.. If you decide to keep the new esc and you dont have a programmer I have a stock esc programmer for sale..

                              you can run 5s on the stock esc
                              It's easy with the card. http://www.horizonhobby.com/ProdInfo...ing_Module.pdf

                              Also set the motor timing to "HIGH" with the stock motor and make sure throttle curve is "LINEAR"

                              Yup you can run 5s. I been doing it for a while. Dis-able the bec and run a rx pack and change all the bullets over to 5.5mm or higher (stock 3.5mm & deans won't handle it)
