johannesjuergens Yes, same problem - on hard corners there are problems with roll. Most of the time it ends in a crash. Found a comment on Jhemcu Facebook page of a user with same problem.

johannesjuergens i think the answer "No, the output pins do not work on these LEDs, so they can't be used in series" is not correct. I have done a messurement with a continuity tester and found that the output-side labels are not correct. The one that is labeled as "Output" is not output, that is GND! And the one that is labeled as GND is the real signal-out. I havent tested it yet because my quad is not ready, but i think that could be the problem. After soldering correctly they possibly should work with betaflight
