Using these on a quad-copter using Quanum MT Series 3510 360KV motors on 6s. the setup i have could be a bit big for these but they are performing very well so far after 5 flights. I did install small vga heat sinks on them as i was a bit worry about the heat but that is now solved, placed them in the prop wash, running cool now.. the esc seem responsive, no need to flash them..Purchased three of these for a HV 6S tricopter. They are tiny compared to other lower voltage ESC's. Soldering quality is excellent and they do the job. They get warm very quickly on 6S. I am not sure if i want to run 6S for to long on these sec's. Have been using 3S most of the time. They are very smooth to fly, and perform well for my application. Found that the heat sink will fall off the chip sets when you remove the head shrink, make sure to put it back on before sealing them up again after soldering motor and power wires to them. So far so good. Have not changed any settings just yet so can not comment on the correctness of the manual in the files tab. Just soldered them in and went flying. Good no fuss SC.
