Looking for the missing prop

Working Progress:

• Continued search in the morning for the missing prop, in vain

• Michelle estimated drag polar from data, which agrees with theory reasonably well

Remaining Issues:

• Need to estimate V_stall and some stability derivatives from relevant segments of log data

• It would be nice to write a python script that, by calling sdlog2_dump.py, not only converts the .px4log to .csv file, but also calculate flight duration and distance

e.g. $convert.py log.px4log > log.csv

Flight duration is ()s.

Flight distance is ()m.

time in seconds = TIME_StartTime*1e-6

t_takeoff: ADAT_Dgps starts to decrease (negative)

t_landing: ADAT_Dgps

integrate V = || ADAT_u,v,w || from t_takeoff to t_landing
