Report for week of 9/17

  • Monday 9/17 was holiday.
  • We optimized the trim mass on the SF to get more balance torque with less total mass. We now have a reserve of 480 g for the yaw pico.
  • We set the SF damper gap to 6 mm.
  • We set the SR2 pitch with the optic lever, aligned the IRM, and set all the OSEMs to have good clearance and midrange output.
  • We locked the SR2 suspension, craned it into the tank and hooked the LBB damper rings (but not the LBB yet).
  • With help from Ohishi-san, we removed the First Contact from SR2.
  • Mark did an audit of all the electronics boxes and updated the item list and S-number file cards on JGWDoc.
