Where can I get the v19 software from? I can only find download links for the new v20? I have a similar issue with mine, where the motor sounds like its running rough when the sensor wire is connected. I've tried every possible combo (even tried muchmore v20 software on the esc) and it still does it.
Runs rough (and noticably loud) at mid rpm, but if I back the throttle right off the rotor eventually stops spinning and whines.
Doesnt occur when running sensorless.
