I have discovered the logfinction of my APM 2.7 flightcontroller.
It is great to be able to evaluate the behaviour of your quad.
I am only having a problem. Flight time with my battery is about 22 minutes.
It seems that the memory capacity of the APM is not enough to keep the whole 22 minute flight.
Does somebody know how much memory there is in the APM?
Can I change settings to get my whole flight in the memory?
Is there a possibility to expand the memory with for example a memory card?
