Hi, I have an PNP HM x12 fc in a 3 inch 2s toothpic build running beatflight 4.3. When using a 1s lipo it flies nice. When using a 2s lipo it frieks out on arming.I have updated ESC's to bluejay. I have changed pids and rates. I noticed when I disable bidirectional dshot it will fly but not good. I have tried HM Bassline dump file. I have contacted Happy Model and they said they dont no why this happens. I have two x12 FC's and this happens to both. Anyone have a idea why this happens? I have spent a lot of time on this but cant figure it out. THANKS
