3 Speed controller stopped working...

[DrekeRc]

I now have 3 controls that I can't longer power on, the first of Hobbyking, a month or 3 ago, suddenly stopped working, soldered the switch again, but that did nothing out. Then I bought a new 2nd hand VTX10r, a Viper, which did it for 3 rounds, and could still steer, but didn't give any motor anymore, and the lights did it too, I also felt nothing special or not normal behavior for that, so I don't think it will have been the motor sensor? Bought a new viper again, this time I got a new one, after 1 race, stopped driving, turned him of NORMAL with the switch ! Wan't to turn him on again, but can't get reaction, looks exactly like the lipo is not connected, just no reaction, tested with diffrent Lipo's aswell ! No clue why

Now I wanted the first Viper to test one more time, beacuse that was the only one I still could turn on. But than, I also couldn't turn that one on anymore, all that in such a short period of time.

I have a suspicion that this is not a "coincidence". I also don't know what kind of things can cause this ...

Does anyone know what this can be? Still coincidence? Bad Lipo batteries? Hard impact? or bad sensor plate on motor? (even though I felt nothing, and the last of which went with a new motor was)

I now have a new HW v3.1 bought, I would like to know if there are things that can cause this, so I can avoid it on the new one.

The weird thing is that this happens is with 2 different types of esc's. Have also been tried with different lipo packs ...

Someone more on this? Hopefully? Thanks

The last one is the wierdest, so I would really like to know what it is with this one, no solution because he is broke I think, but just a reason why...
