Apparently, most Tiny Whoop pilots fly autolevel. This was news to me, but hey, when in Rome... so I fly my Betaflight Newbeedrone Acrobee in Angle mode.
If you use Betaflight angle mode, but your quad doesn't hover level when you center the sticks, I'm going to show you how to fix it. You need to calibrate and trim your accelerometer.
If you have a Betaflight-based Whoop, you MUST check out Project Mockingbird. I haven't tried it myself yet, but I've been told by one pilot that it comes as close as possible to Betaflight matching an Inductrix-based Whoop's handling.
