I don;t know. Maybe it is possessed after all (although the BT7 that carries this controller has Russian icons for extra protection). http://s148.photobucket.com/albums/s30/ChrysKane/BT-5/?action=view¤t=BT7driverwicons.jpg http://s148.photobucket.com/albums/s30/ChrysKane/BT-5/?action=view¤t=Bt7wricons.jpg Or maybe I should take the icons out, in case I went blasphemic trying to be historically faithful ! This is a new ESC. The older one just fried when a cable got stuck in the tracks, and drew tons of amps . Quite spectacular, actually (I added fuses after that). The older ESC was doing the same trick on this tank with the same RC receiver.
If it is affected by vibrations and shocks, it has to be suspended from springs. Do ESCs need to be suspended from springs? I think I have seen this somewhere, in Neal's tanks? Could be wires running close to it, or just a cage effect. All of my tanks are metal. The Saber ESC sits on spacers, on a wooden table with an MDF plate and has a large hole under the ESC itself. Plus teh 12 V fan. Anyway, it is not a major major problem. When teh confused ESC goes nuts, I run and kill teh power, and it resets.

All of the sudden, and even when teh batteries are fully charged, it goes insane. Usually what it does is it goes reverse at full speed and jams there. If I kill the power from teh killer switch, it resets and is "collaborates" with my RC. I installed a 12 V fan on 18V current blowing air on the ESC and still does teh same unpredictable tricks. I now wonder if it is affected by shocks and vibrations or if there is a short circuit somewhere . I checked for teh latter again and again. Couldn't find a leak. Chrys we had a similar problem in my dad's one submarine, the rudder servo would just peg all the way over to one side BUT this only happened when we were testing it in the one neighbor's pool, but if i went to another neighbor's pool, there was no problem. it only happened in the one pool. is it possible something in your tank is effecting it? maybe some rare fluke with your radio system or main power feeds? any other wires come close to the speed controller unit or the wires leading to it? did you try this unit in something else to see if it still does it? possessed tank?
