Hello @moldover!
Yep, you found a bug!
Tested and found the same thing, seems we didn’t test it aggressively enough before 
I tried a pretty simple fix and it seems to work for me, but please if you still find something glitchy let me know: ytx-v2-firmware-0-21-dead-zone-0-fix.bin (111.5 KB)
It’s a firmware to be used with the latest Firmware manager, and if you haven’t yet upgraded to v0.20, it’ll be mandatory to follow the steps to upgrade firmware AND configuration described in this post
Cheers!
