If I could I would give this ESC a negative 5. Pure garbage. I purchased two, being the optimist. $30 down the drain. The first one didn't make it off the test/programming bench. While I was attempting to program "soft timing", the sound output, to the motor got very faint and almost not audible. Then about 30 seconds later, it started smoking. The second one... smoked during minute 4 of the second flight. Luckily, I was just hovering.

I got this ESC a week ago and had it hooked up to a 1400KV motor with a 3S lipo that was pulling 30 AMP. It immedialte whent up in smoke. HK support told me to take a video and send it in. I asked if they were really asking me to hook it back up and then they said no. They advised me to Email their support email. For 3 days I have no response other than. "We received your email." ESC is crap and so is the service. I guess you get what you pay for.
