I have never tried to use the flight log on the GPS so I have not seen what the data looks like. I am wondering if it records each lat and long that the copter moves. Seems that would be a big list. If it does not have that ability does anyone know of a way to achieve this? I see some GPS data loggers out there but they record every 5 seconds and others are 10. The copter will have moved quite a bit in that time frame. I would like to have the data for every change of a say a meter.
