Angel, thanks for trying. Pretty funny video, impressive it still flies at all. Speeds faster than 230K baud may improve it -- I'm not sure what the practical limit is on the UART.
Regarding the i7 laptop (and M4/USB), have you tried running the sim with different sensor output rates? That's the "-rs <Hz>" option. Bumping it to 800 Hz may help.
Cheers,
