So I am building a multi-rotor, an octo. It has 8 RC Hobbies ESC 70A Brushless Motor Speed Controller and 8 RC Hobbies ESC 70A Brushless Motor Speed Controller, both from rctimer. I wired everything up but when I put power to it, one of the ESCs began smoking. At first I assumed I must have had a wire crossed, but after going over the model carefully with a voltmeter and doing continuity checks, I found the only place was that particular ESC. With that in mind, I disconnected it and tried again. At first it seemed fine, but when the transmitter was turned on one motor, completely separate from the bad ESC mentioned previously, released smoke and briefly caught fire before the battery could be unplugged. After carefully re checking every thing and leaving the damaged motor and ESC disconnected, I tried once more. This time a capacitor on yet another esc blew out. I have checked my wiring system visually and with a voltmeter and no short circuit is apparent. anyone else ever had similar troubles? Thoughts?
