decent motor (some vibration and some run-out, but I did not measure it yet)
very bad controller.
the power input wires became disconnected during testing =>
the 12V DC/DC converter blew up and took out the H bridge driver - and that one is impossible to find
luckily the MCU escaped, the input voltage was just 20V and the MCU's regulator was able to handle that.
now it's time to try and fix it
