Yes, available on steam.
Use a btfl_00x.bbl file corresponding to one full flight. (one LiPo). See the full guide here. Simply try another one if you are not happy ! It’s best to have a good run without crashes or wind. Ideally :
Accelerometer should be on, else extraction cannot works.
Logging frequency of 500Hz is best : extraction will only be longer with higher frequencies without any gains.
No need for any DEBUG settings.
