  • I think my viper 10 blew up

    I bought a 3.5 dual motor sub driver and a viper sub 10 controller. I am in the process of putting all the equipment together. I connected all the electronics together except for running the wires from the controller to the two motors. I used a dean connector from my 11. 1 lipo and made sure I had proper polarity. the controller led flashed and supplied power to my reciver and servos which worked properly. my snort pump which is connected directly to the battery was functioning properly. I un plugged the battery then connected the two wires from the controller too the two wires from the motors. I then plugged the battery back in and the controller did nothing no flashes no power for the bec. I then unplugged the battery and cut the motor wires. I replugged in the battery and the system is still dead. What should I do now and what should me meter read across the two motors to prove that they are good or bad. Did my motors blow up the controller?

    Robert,

    A very similar thing happened to Mr. Caswell -- he managed to blow up his Viper-10 ESC in a like arrangement. Very unsettling to say the least. Hope we don't have a systematic problem here.

    (Mike is my resident 'Angel Of Death' -- I send new product to him, if he can't screw it up in four-hours, then I know I have a bullet-proof product that can be release to the general public with good assurance it won't fail).

    My first guess is that there is a short somewhere in the wiring between the motors and the output of the ESC -- check for that.

    Did you forget to re-plug the three-wire lead from the ESC into the receiver channel-3 port?

    A continuity check of the motors is a waste of time, you'll only read one set of pole windings at a time. Best just to hook up the battery straight to the motors and see if they run (after checking your motor wiring clean of any shorts) -- do not do this with the ESC hooked up, you'll kill the ESC for sure.

    But, it sounds like your ESC has lost the magic smoke. Hook up a 4.5 (receiver) battery to a receiver port to insure all the devices still work (take the ESC plug out of the receiver for this test -- better yet, cut its input wires).

    We'll walk you through this. Get back to me after performing the above.

    David,

      David,
      I was going to write my standard reply to this sort of retort from The Wizard, but then my wife told me I couldn't use that particular phrase here.

      Oh! Yes, and I also managed to break that really flimsy Snort manifold on top of my sub-driver. The little brass tube had about 1/96" or resin around it. **** poor design - not idiot proof! Umm What did I say? Err I mean - not well designed - even for the discerning modeler.
      Stop messing about - just get a Sub-driver!

        Good job, Mike. Between your posts and mine we just chased away the last of our prospective customers.

        Oh ... and you forgot to mention to the guys: the cylinders, in a cost savings effort suggested by you, are now fabricated from gelatin. And all power cabling is now bare wire aluminum conductor, not that expensive insulated stuff.

          I seem to recall you posted the following about one of my posts that was somewhat similar to this.

            motors work great off the battery. rx battery plugged into the reciver makes everything work fine. The leds on the esc would not light up when it first died and now since it is not connected at all it will never light up again. I tried connecting power straight back into it and got no leds

                  Plug in a new ESC. Seriously.

                      No. Honestly, Robert, no warranty on the ESC's. They are subject to this sort of thing. I too suffer the occasional ESC failure, and the only thing for it is to replace the unit.

                        I'd like to see what Mtronics has to say about this. Do they want to look at these units? Lets find out.

                          they are usually pretty bullet proof, you sure it was connected correctly
                          Next time someone points out it takes 42 muscles to frown, point out it will only take 4 muscles to b1tch slap them if they tell you how mnay muscles you need to smile:pop

                            I followed the directions to a T the primary test before connecting the motors into the circuit went great, it powered up the reciever and the servos fine. I unplugged the battery and connected the two wires that ran off my motors to the two motor connectors for the esc. I then plugged in the battery and the esc was toast. I have tested the motors off the battery directly and they both run well.

                              We have sold a lot of these units and never had a problem until this weekwhen I blew one up as well. So, I've never challenged Mtronics about warranties - I've had no need. I can't say it was my wiring because Mr. Merriman did the wiring, so maybe we do have a batch problem. Having said that, I wired in a new unit and so far, it's behaving perfectly.
                              Lets see what Mtronics say, hopefully they can get back to us on Monday. Maybe we'd best send the units back for their inspection?
