The only thing I happened to notice from the pictures is that the controller has the black BEC jumper intact, which suggests that you are using the controllers BEC. It is in fact rated for 12 cells, but the xl motors can "ask" for a lot of power, which in conjunction with the "heat" generated by the bec could be heating things up pretty badly. Despite the 12 cell rating, it is usually best to run a receiver pack or UBEC when using 8 or more cells, due to the heat generated by the excessive voltage (bec is trying to "get rid of" the extra 8 or so volts). The gearing shouldn't be too far off at all, actually. I would try a receiver pack as the first step.
As for the steam....well I don't know. If the caps vented, that could be considered very bad. If they didn't vent, then steam suggests moisture, which is also considered bad! Try a receiver pack(and remove the controller's bec jumper) and report back.
