The UBEC seems to be the culprit for the start-up voltage dip. If the battery is first connected to the UBEC and only after that it itself is connected to the rest of the circuit, everything works ok. So it seems the UBEC needs settle for a moment before it can properly supply the whole circuit. Unfortunately the servo doesn't care for such tardiness and resets immediately.
