This seems to be well made. At least, the package (Shrink tubing around the board) is very nicely done and the label is well made and placed nicely. I have used this with a 50mm EDF using 4S batteries and it performs well. I used an ifrared thermometer to check the temperature after an almost all full-throttle flight to and it only logged 130 degrees. I have tap water in my home that hot!

Can't give a full honest review as I have not even flown my RC plane with this ESC in it but I've used it and other planes of a different size and seem to work fine

Good ESC for whatever you want to use it for.The slim profile and long cords allow for use in RC cars as well as drones.

Horrible ESC! Turned on with 3s after a minute later it started smoking. Would never buy again.

Soldering quality is bad and larger heatsync and better heatsync compound is required to not release the magic smoke near a sustained 30 amps.. I'd guess they're actually rated for 20-30 sustained with 40A burst. But for the price I'm willing put in the work to preemptively fix the shortcomings before the FETs go out in a blaze of glory.

Needed a speed controller for my drone and this one worked out of the box!

im giving this 3 stars because the other esc works great and I'm replacing the defective. But I have major concerns about the lifespan of this esc. 1 of them broke after maybe 20 minutes of testing. Remember, i used the same motor, transmitter, and battery for both escs. I was not stress testing nor were the motors even mounted to anything of use, I was simply to see if a signal would be supplied and if the motor would turn. At least the esc is being replaced by amazon, but what happens a few weeks into ownership when an esc gives out for being asked, well, to do simple esc things?

I have gotten 2 of these. Each time it would work for a bit, then it would not "arm". it will beep twice, then all other servos work, but the motor will not throttle. I have over 25 ESC's, and only these 2 don't work. I have tried to set throttle levels, different rx, rebinding, nothing.
