I am using my APM 2.6 as a "smart" data logger for a vintage rail dragster which i am on the team for as their "engineer". I have some experience using the APM with RC planes and quadcopters and decided this would be a good way to get some velocity and acceleration data with the benefit of gps location thrown in. it's nice to get IMU and GPS accel and velocity data both. we used the device on 15Mar14 for the first time and i overwhelmed the log storage capacity of the APM so i am looking at ways to either increase that or reduce the number of parameters that are saved.
I would like to limit the parameters being save to what i need or be able to turn the logging on or off using the MAVLINK telemetry. any suggestions would be greatly appreciated.
