Yesterday 01/04/11, we removed 425g of addable mass from the Main Chain UI mass on Quad 2. The remaining addable mass (114g on the top and bottom Turrets, total 228g) was placed to reestablish symmetry on the UI. The Quad is now sitting at 20.5mm above the LS frame. The Quad has been rebalanced and aligned. Mark Barton is running transfer functions.
