So, a few words about this FC: There is a known hardware defect that prevents the use of bidirectional Dshot. The manufacturer already knows and has released V2 of this board but for some reason keeps selling bad V1 boards. If you search for it on the internet, you will find many complaints about it. The manufacturer said bad in principle, do you want a discount on our v2 version with this corrected version? This is also not bheli firmware on escs. I wanted to love this FC so much but it never flew and I tried every workaround I could find. Even following the recommendations, I can get by with different firmware combinations, but still can't get going. Stay away from iflight from now on.
