We are showing modalai at the largest formal aerospace conference in Africa.
 We have purchased a sentinel 2 dev kit and our coders are learning the code and commands. However, we don't think we will do your product justice in time for the conference.
 Is there anyway u can share a “wow” piece of code to showcase your product. For now we are planning to just use the figure 8 flight path modalai preprogrammed with purchase. But we both know this is very basic compared to what your drone can do. Any help would be appreciated.

On another point; one of our coders messed up the calibration. The drone footage flashes with the light intensity fluctuating. Could you possibly send us a flash to get the unit back to original calibrated  purchase from you.

Hi Boyzie, maybe you could run the figure 8 with [voxl-tflite-server](https://docs.modalai.com/voxl-tflite-server/)?

Can you please share the serial number of your drone? We can try to find the calibration files

What light is flashing? Can you share a video?

If the unit needs to be reflashed, you should install the [system image](https://docs.modalai.com/voxl2-system-image/) and then perform [camera calibration](https://docs.modalai.com/calibrate-cameras/)
