There could be a couple things going on that I can think of. I’m not as familiar with the hub though because I’ve only dealt with batch 2 before the hub was introduced. But I have the new hub schematic in front of me right now. It could be one of the following:
a) there is a disconnect on any of the lines between the throttle and the hub. For example, it could be a disconnect on one of the communication lines inside your throttle, possibly on the connector inside the throttle.
b) there is a disconnect between the hub’s PWM or GND and the ESCs. This would be less likely because it would mean all four ESC’s have a disconnect. Or it means you plugged all the ESCs into the hub backwards. Don’t go flipping them around just yet though, because that may damage your ESCs.
Are you able to open up your throttle and inspect the connector to make sure none of the pads have lifted?
