Which Cube will withstand high g-forces?

I’m developing a flight recording system and visualisation application for aerobatics in full sized aircraft. This is a purely a recording device and I’m using Ardupilot’s logging functionality.

Competition aerobatic aircraft can pull upto +10g and (obviously fly inverted). Ardupilot’s EKF system works very well at low g forces (4g) with cheap flights controllers, but at higher g forces, the EKF shows step corrections and in bad cases becomes unstable . I’m not sure if it’s the GPS or the flight controller.

I can’t find any mention of maximum acceleration values in the documents. What g-force will the various cubes handle?
