Logging Rate in BIN File is not Sufficient

Hi, I am using a Kakute H7 controller with a Holybro M10 GPS in an aerobatic model airplane.

I am using the new Blackbox feature in ArduPilot Plane (custom firmware), designed to disable most functions for drones, but to record data from the controller and GPS module to a microSD card.

The goal is to evaluate the data on the SD card post-flight using FlightCoach and FlightScore.

Now, when I open the BIN file for evaluation with FlightScore, I get the message: “The logging rate in this BIN file is not sufficient for FCScore (15Hz; we expect about 20Hz)…” (see the picture above).

In theory, the logging rate is controlled by the parameter: LOG_FILE_RATEMAX

This parameter was set to 30Hz. Then I increased it to 40 Hz with no change.

The log-rate insufficiency message does not seem to be dependent on the microSD card.

I tried several of them at high speed, with no change. I am currently using an 8GB Kingston U3V30 card.

Has anyone had this type of problem? And if yes, how has it been solved?

Thank you very much!
