BSC Unit 3 Twist: The Retwistening
It was discovered last night that an actuator link block had been left on one actuator. This part was likely responsible for the reduced twist on unit 3 after the last round of tinkering. We now have a rather large twist(not sure of the size just yet), but it is in the opposite direction from what we had previously. It appears that this rotation is very sensitive to Stage 0-1 flexure position. For the moment, we plan on readjusting the flexure position in one corner only, maybe we can tune the rotation one corner at a time.
