Hi all. Done a few calibrations in the past just by reading the instructions in the go 4 app. When it comes to the second part, it says to point the spark nose down and rotate 360, no problem there, but, the picture description, has the spark showing in a horizontal not vertical position. Which one is correct? Sometimes it takes 2 full 360 turns with the camera pointing down for it to say calibration complete. Cheers in advance.
