I had the FET in the transmit voltage booster. Short out. Basically putting a 9 Ohm coil from raw +12 volts to ground. Though in that case it was accompanied by some smoke and the +12 was very low.
Was a fatal flaw in the original 2.4 firmware. Seems during a Factory Reset. The FET was turned On continuously and shorted.
