Thank you for your reply. No, the Nazgûl has the Blitz Mini and the TanqS has the Goku AIO. I did get the Nazgûl to arm. I restored Betaflight from a backup. The TanqS, I unfortunately didn’t have a backup of. I was going to see if Rotor Riot had the file. It did seem that when I recalibrated the sticks on the RC3 is when the Nazgûl armed?
