Started to test T-Motor MN3110-17 700KV with 12X40 Tiger CF props for my new Y6 build, but my 30A simonk flashed ESC was getting so hot on 3S lipo and after trying 4S it got cooked. ESC32 was next in the test and performed well no heat and no problem running with this motor, but its too big to fit inside the center plates, looked around for something much smaller and Felix and Paul from flyduino.net had exactly what I was looking for.
It is small, even with the capacitor it's half the size of regular 20-30A esc, (now I'm thinking about using 20mm tubes and fitting esc inside)
Did few tests here and on 4S without any cooling it won't go over 20°C.
Another cool feature is the Configurator (Google Chrome extension so it will run on any OS ,not mobile )
And the best feature is Spin Direction option so no more resoldering :)
Also if someone looking for experimenting with 3D copters, this esc will run in reversible mode with modified props.
Here is warthox going crazy as usual:
