ther emust have been some kinda symoltanious failure.
so by coincidence after you updated the firmware there might have been a stack on your previous run....might have allowed some arking from the main power board to get onto the BEC board
bad luck :(

the porthole from the noob world an here has been opened!! that's how i got in.
This weekend I ran the first 2 qualifiers with the previous Firmware and then the 3rd qualifier and main race with the updated firmware.
No problems.
The throttle response felt "smoother" to me with the update.
