So just to be clear, I'm not reading the horizon wrong, it appears to be off by 90 degrees, and this is a prebuilt arris 250 and the FC came installed this way. The wiring does not easily allow a 90 degree rotation. I did flash new firmware to the FC and set everything else up successfully. Is there anyway to rotate the artificial setting horizon without re-wiring the body? Could an incorrect firmware be the issue?
