Hi!
I am relatively new to RC and had built my first F450 drone 1-2months back. I used FS-I6x transmitter and it had been working well and suddenly started throwing error "Warning, Place all switches in their up position and lower the throttle" even though all switches are up and throttle down. I had tried cutting 1-2mm from the throttle stopper but still, the error is thrown. Any help would be wonderful. Thank you.
