This test is a repeat of the December test (linked here) to verify the segmented-preburning-preheater success was not a fluke.
According to thrust_curve_tool this is an
7 second burn
Looks good. The motor came up to pressure quickly and cleanly. The difference in performance from December is the use of a dip tube in the previous test to conserve Nitrous. No dip tube was used this time.
Time to fly!
