- Travis, Cheryl MC1 had significant bias settings in both pitch and yaw after aligning it to get the mode cleaner flashing. These were zeroed by moving the pitch adjustment mass, and tweaking the blade springs. OSEMS were recentered. MC3 OSEMS were recentered. This morning I'll get a good MC alignment while I have access in HAM2 if needed, and verify the health of the changes we made yesterday in regards to alignment.
