Outstanding/key items:

• LTC6820 demo board availability is poor for steering module control boxes. Liverpool has 4 on order but delivery has slipped to DEC 16.
• Tile/vPDU testing status? Current estimate is that vPDUs will be made available for the cold test stands in January.
• vPDU vacuum bagging
