BTW, the 51515 hub has an issue with pitch readings. When I tilt the hub along the pitch axis and you are almost perpendicular with the ground, the readings will go 80, 81, 83, 83, 83, 83.....then goes to 90.
I've mentioned this 3 times to LEGO and either I get.."We will fix this on the next update" or I they reply that they don't understand what I'm talking about.
Anyone else seen this on their hub?
